- ADO.NET
- Access Data Objects (.NET version) – the suite
of data access technologies included in the
.NET Framework class libraries.
- analog
- The form of data comprising a full range of
possible variable values, represented in a signal as a changing value
over time. Compare with digital.
- ANSI
- American National Standards Institute – a voluntary, non-profit
organization of U.S. business and industry groups formed in 1918 for
the development of trade and communication standards. ANSI is the American
representative of the International Standards Organization and has developed
recommendations for the use of programming languages including FORTRAN,
C, and COBOL.
- API
- Application Programming Interface – the interface
formed by a set of programming language constructs or statements which
can be coded in an application program to invoke the specific functions
and services provided by an underlying operating system
or service program.
- ASCII
- American Standard Code for Information Interchange - a coding scheme
using 7 or 8 bits that assigns numeric values to up to 256 characters,
including letters, numerals, punctuation marks, control characters,
and other symbols. ASCII was developed in 1968 to standardize
data transmission among disparate hardware and software
systems.
- ASP.NET
- Active Server Pages (.NET version) – the framework
for building server-based Web applications. An evolution of ASP into
the managed code space.
- assembly
- A collection of functionality classes, built, versioned, and deployed
as a single implementation unit (one or multiple files). An assembly
is the primary building block of a .NET application.
All managed types and resources are marked
either as accessible only within their implementation unit or as exported
for use by code outside that unit. In the runtime,
the assembly establishes the name scope for resolving requests and the
visibility boundaries are enforced. The runtime can determine and locate
the assembly for any running object because every type is loaded in
the context of an assembly. See AssemblyManifest.
Compare with namespace.
- assembly manifest
- An integral part of every assembly that
renders the assembly self-describing. The manifest
metadata establishes the assembly identity,
specifies the files that make up the assembly implementation, specifies
the types and resources that make up the assembly, itemizes the compile-time
dependencies on other assemblies, and specifies the set of permissions
required for the assembly to run properly. This information is used
at runtime to resolve references, enforce version
binding policy, and validate the integrity of loaded assemblies. The
self-describing nature of assemblies also helps makes zero-impact install
and XCOPY deployment feasible.
- asynchronous operation
- 1. A process in a multitasking system whose execution can
proceed independently, or in the background. Other processes may be
started before the asynchronous process has finished.
2. A data transmission method that allows characters to be sent
at irregular intervals over a line by preceding each character with
a start bit and following it with a stop bit.
Compare with synchronous operation.
- attribute
- A descriptive declaration that annotates programming elements such
as types, fields, methods, and properties. Attributes are saved with
the metadata of a .NET
Framework file and can be used to describe code to the runtime or
to affect application behaviour at run time.
- audio frequency
- The frequency at which a sound wave is audible to the human ear
in the range from 150 to 20,000 cycles per second (HertzHz).
- AV
- Audio Video the general name to describe equipment and
devices which support audio and/or video capabilities.
Often used to describe cables and connections between compatible equipment
for the transmission of video and audio signals.
- bandwidth
- 1. The difference between the highest and lowest frequencies
that an analogue communications system can pass. For example, a normal
telephone line accommodates a bandwidth of 3,000 Hz, which is the difference
between the lowest (300 Hz) and highest (3,300 Hz)
audio frequency range it carries.
2. The data transfer capacity of a digital communications system.
- BIOS
- Binary Input Output system a
- bit
- Binary digIT a single basic unit of binary data
represented as being either on or off in a digital
signal or stored on digital media.
- build environment
- The state of the development workstation and the directory structure
when an application build begins. Compare with runtime.
- cache
- A special memory subsystem in which frequently
used data values are duplicated for quick access.
A memory cache stores the contents of frequently accessed
RAM locations and the addresses where this data is
stored. When the processor references an address in memory, the cache
checks to see whether it holds that address. If it does hold the address,
the data is returned to the processor; if it does not hold the address,
a regular memory access occurs. A cache is useful when RAM accesses
are slow compared with the microprocessor speed, because cache memory
is always faster than main RAM memory.
- CD
- Compact Disc – the lightweight, removable and portable 12cm standard
optical disc media for storing
digital data. (Note the spelling
using "c" in 'disc', as apposed to 'disk' used to describe magnetic
media.) CDs were designed to replace records and
tapes as audio storage media, and require the use of special hardware
equipment known as CD players. More recently, re-recordable CD media
and CD recorder devices were made available allowing for custom data
storage.
- client
- 1. In object-oriented programming, a member of a class (group)
that uses the services of another class to which it is not related.
2. A process, such as an application or task, that requests a
service provided by another application. For example, a word processor
that calls on a sort routine built into another application. The client
process uses the requested service without having to know any working
details about the other application or the service itself.
3. On a local area network or the Internet, a computer that accesses
shared network resources provided by another computer, called a
server. The client primarily presents data to
the user. As a rule, the client (or front end) does not perform any
calculations; instead, the client sends requests for data to a server,
and then formats and displays the results.
- CLS
- Common Language Specification – a defined set of
.NET Framework language features, designed
to allow objects to fully interact with other objects regardless of
the language they were implemented in, by exposing to callers only those
features that are common to all the languages they must interoperate
with.
- COFF
- Common Object File Format – in 32-bit programming, a format for
executable and object files that is portable across platforms. The Microsoft
implementation of COFF is derived from the UNIX specification for COFF,
but includes additional headers for compatibility with the MS-DOS and 16-bit Windows operating systems. The Microsoft
version is also called the portable executable (PE)
file format.
- COM
- Component Object Model – an open architecture for cross-platform
development of client/server applications supporting infrastructure
for building, using, and evolving component software in a robust manner.
COM is an object-based programming model designed to promote software
interoperability. It allows two or more applications or components to
easily cooperate with one another, even if they were written by different
vendors at different times, in different programming languages, or if
they are running on different machines running different operating systems.
COM defines the interface, similar to an abstract base class, IUnknown,
from which all COM-compatible classes are derived.
- COM port
- Communications Port – the logical address assigned by MS-DOS versions 3.3 and later, and Microsoft Windows, to
each of the four standard serial ports on an IBM personal computer or
an IBM PC-compatible computer.
- common language runtime
- The engine at the core of managed code
execution. The runtime supplies managed code with services such as cross-language
integration, code access security, object lifetime management, and debugging
and profiling support.
- CRT
- Cathode Ray Tube the HMI technology used to create
TV and computer monitor display
devices involving the use of a custom shaped and
sealed vacuum glass tube containing a matrix of coloured phosphors at
the viewing end, which would emit light when struck by electrons fired
from the other end of the tube and aimed using powerful electromagnets
within the tube. The combined effect of the very many phosphors emitting
light at very nearly the same time across the viewing screen formed
a visual image for viewing by humans. The three phosphor colours found
to be most practical were Red, Green and Blue, which when positioned
very closely and combined in different intensities, produced the optical
illusion of nearly any colour and intensity.
CRT TVs were totally self contained including power supply, CRT, electronic
control circuitry, and TV signal decoder. When CRT monitors were created
for computer displays, a higher resolution (than standard TV resolution
of the day) was required in order to display finer detail when viewed
close-up (as monitors were placed on the desktop directly in front of
the human—not viewed from across the room as TVs typically are). The
TV tuner and circuitry was removed, a higher resolution CRT was used,
and the higher resolution RGB signal was sourced externally from the
computer graphics card. The analog
RGB signal was sent directly between the computer
and the monitor using a special RGB cable, and connected directly to
the analog monitor display circuitry with no tuning or signal processing
required by the monitor.
CRT display devices cannot be connected to signal sources using
AV cables as they do not contain video interfaces
or video control circuitry hardware.
- DAT
- Digital Audio Tape a magnetic tape used to store
data in a digital format
media, most often used for digital audio recordings.
- data
- The raw (uninterpreted) symbols or facts suitable for processing
by computer or transmission over a communication medium, often in the
form of bits grouped into bytes representing
ASCII text characters arranged into strings. When
interpreted with meaning, produces information.
- design-time
- Design-time functionality refers to the display and behaviour of
a component or control in a visual designer. Design-time tasks include
showing a component or control in a tool box, displaying a component
on a design surface, showing properties and events in a property browser,
automatically generating code, and so on. Compare with
run-time.
- device
- In the context of computing, networks and communications, a device
is a machine or piece of hardware serving a particular purpose. For
instance: a PLC, a computer, a communications port,
a storage disk drive.
- digital
- The form of binary data comprised of ones and
zeros, represented in a signal as a single bit being
either on or off. Compare with analog.
- display
- The HMI device creating
an emission of light to form a visual image upon its display surface
for human interaction. Analog displays use
CRT technology, whilst digital
displays use PDP (plasma) and LCD
display technologies.
- domain-neutral
- The practice of loading an assembly without
specifying a domain in which the assembly is to run. Loading an assembly
in a domain-neutral manner enables the assembly's code and associated
run-time data structures to be shared among all application domains
within a process.
- DOS
- Disc Operating System – the operating system originally designed
for IBM PCs to allow for file read/write operations
of data and programs to and from disk for computers
to compute. See OS.
- DVI
- Digital Video Interface – is a new form of video interface technology
made to maximize the quality of flat panel LCD monitors and high-end
video graphics cards. It is a replacement for the P&D (Plug & Display)
standard, and a step up from the older DFP (Digital-only Flat Panel)
format. DVI is becoming increasingly popular with video card manufacturers,
and most cards purchased include both VGA and DVI output ports.
There are three types of DVI connections:
1. DVI-A (Analog)
2. DVI-D (Digital)
3. DVI-I (Integrated Analog and Digital)
DVI digital and analog formats are non-interchangeable. This means that
a DVI-D (digital) cable will not work on an analog system, nor a DVI-A
(analog) on a digital system. Make sure that you know which format each
device can support before you purchase any DVI cables. Only equipment
with a DVI port labeled 'DVI-I' will accept both a DVI-D or DVI-A source
signal (but not both at the same time, and not from one to the other).
- DVI-A
- DVI-A (Analog) format is used to carry an analog
DVI signal to an analog display, such as a CRT monitor or an HDTV
equipped with a DVI-A or DVI-I input. This allows
for connectivity between analog video source devices and compatible
digital display devices using analog signals. DVI-A transmits a higher
quality picture than standard VGA. Compare with DVI-D
and DVI-I.
- DVI-D
- DVI-D (Digital) format is used to carry a digital
DVI signal to a digital display, for direct digital connection between
source video (namely, video cards) and digital LCD (or rare CRT) monitors.
This provides a faster, higher-quality image than with analog (DVI-A), due to the nature of the digital format. All
video cards initially produce a digital video signal, which is converted
into analog at the VGA output. The analog signal travels to the monitor
and is re-converted back into a digital signal. DVI-D eliminates the
analog conversion process and improves the connection between source
and display.
- DVI-I
- DVI-I format is an integrated cable which is capable of transmitting
either a digital-to-digital signal or an analog-to-analog signal, but
it will not convert signals from digital-to-analog or analog-to-digital
between devices.
- executable file
- A file in portable executable (PE) file format
that can be loaded into memory and executed by the operating system
loader. It can be either an .exe or a .dll file. In the
.NET context, a PE file must be translated by the
common language runtime into native code before it can be executed by
the operating system.
- expression
- Any combination of operators, constants, literal values, functions,
names of columns, controls, and properties that result in a single value.

view, dialog box, or button, that permits the object to receive keyboard
input from the user.
- framework
- See definition for .NET Framework.
- FTP
- File Transfer Protocol – the protocol used for copying files to
and from remote computer systems on a network using a Transmission Control
Protocol/Internet Protocol (TCP/IP), such as the Internet. This protocol
also allows users to use FTP commands to work with files, such as listing
files and directories on the remote system.
- file system
- In an operating system, the overall structure in which files are
named, stored, and organized. A file system consists of files, directories,
and the information needed to locate and access these items. The term
can also refer to the portion of an operating system that translates
requests for file operations from an application into low-level, sector-oriented
tasks that can be understood by the drivers controlling the disk drives.
- GC
- Garbage Collection – The process of transitively tracing through
all pointers in the .NET environment to actively
used objects to locate all objects that can be referenced and then arranging
to reuse any heap memory that
was not found during this trace. The runtime
garbage collector also arranges to compact the memory that is in use
to reduce the working space needed for the heap.
- GUID
- Globally Unique IDentifier – a 128-bit system-generated identifier
that is guaranteed to be unique across all network
systems for all time. See Network Identifier.
- HD

or 720-line (1280x720) in 16:9 aspect ratio.
- HDD
- Hard Disk Drive – the mechanical magnetic disk drive
media used to store digital
data. (Note the spelling using "k" in 'disk', as
apposed to 'disc' used to describe optical media.)
- heap
- A portion of memory reserved for a program
to use for the temporary storage of data structures whose existence
or size cannot be determined until the program is running.
- HMI
- Human Machine Interface – the physical means of interaction between
humans and machines allowing for machines to request input from humans,
and for humans to input an instruction, selection or command; also the
use of hardware items such as buttons, keyboards, mice, indicator lights,
display screens, disk drives, remote controls, and software items such
as online forms, touch screen buttons, notification windows, etc. for
humans to interact with.
- HTML
- HyperText Markup Language – a subset of SGML
used to create hypertext documents that are portable from one platform
to another. HTML files are simple ASCII text files
with codes embedded (indicated by markup tags) to indicate formatting
and hypertext links. The formatting language used for documents on the
World Wide Web. For a complete description of tags, attributes, and
extensions, see the HTML specification:
http://www.w3.org/pub/WWW/MarkUp/.
- HTTP

port, and to a communication protocol standard.
- interface
- A programming interface is a related group of function calls. These
function calls are also referred to as "methods" or "member functions."
All interfaces are named. By convention, interfaces are given a name
starting with capital "I", such as IUnknown. This given name
has symbolic meaning to source-level programming tools. Each interface
is also assigned an interface identifier (IID). The
IID is a system-generated 128-bit globally unique identified (GUID)
that unambiguously identifies the interface. The system uses this GUID
at runtime to uniquely identify the interface.
- IID
- Interface IDentifier – a system-generated 128-bit globally unique
identifier (GUID) that unambiguously identifies
an interface. The system uses the GUID to uniquely
identify an interface at runtime.
- ISO/OSI model

purpose to produce ideas, thoughts, and beliefs, through the intelligent
use of comparisons, consequences, connections, and conversations.
- LAN
- Local Area Network – a group of computers
and other devices dispersed over a relatively
limited area and connected by a communications link that enables any
device to interact with any other device on the network. LANs commonly
include microcomputers and shared resources such as laser printers and
large hard disks. The devices on a LAN are known as nodes, and the nodes
are connected by cables through which messages are transmitted.
- LCD
- Liquid Crystal Display – the technology used to control the passage
of light through an electronic matrix display. See
monitor. Compare with CRT.
- lifetime
- The time period that begins when an object is allocated in
memory and ends when the garbage
collector deletes the object from memory.
- managed code
- Code that runs under a "contract of cooperation" with the
runtime. Managed code must supply the
metadata necessary for the runtime to provide
services such as memory management, cross-language integration, code
access security, and automatic lifetime control of objects. All code
based on Microsoft Intermediate Language (MSIL)
executes as managed code.
- markup tags
- SGML, XML &
HTML are ASCII text files consisting
of markup tags surrounded by angle brackets (<>), interspersed with
text. A markup tag may have one or more attributes associated with it.
These attributes modify the layout or behaviour of the tag, or provide
additional information about the source or extent of a given element
of the document. For example, a typical HTML document contains the paired
HTML markup tags <HTML><HEAD> ... </HEAD><BODY> ... </BODY></HTML>,
which define the start and end of the document, it's header information,
and the body content.
- media
- The physical device used to store
data. Digital storage media
includes CD, DAT, DVD, floppy disk, HDD, and memory sticks, whereas
analog storage media includes record and tape. Magnetic storage is used
on tapes (analog and digital), floppy disks, and hard disk drives (both
spelt with a "k" in 'disk'), whereas optical storage is used on compact
discs and Digital Versatile Discs (both spelt with a "c" in 'disc').
Memory sticks store their data in microchip (electronic) memory.
- memory
- In electronic devices, memory refers to the
storage of digital electronic
data in a silicon-based microchip. Temporary storage is achieved
using RAM chips, and permanent storage is achieved
using ROM chips. Memory is referenced using addressing
and is accessed using the underlying BIOS.
- memory stick
- The general group name describing any type of a removable and portable
storage devices using flash memory chip technology or similar in an
ultra-thin design for the storage and transfer of
digital data between compatible
devices. Typical examples for computer usage are
fitted with USB plugs, whilst newer thinner versions for digital still
cameras and mobile phones use ... [COL: list types
here].
- metadata
- Data used to describe other data. For example,
in HTML, a metadata tag holds the description of the HTML topic, and
is used by search engines to categorize and list the content of the
topic in the search engine's database.
In the Microsoft.NET environment, metadata is information
that describes every element managed by the runtime:
an assembly, loadable file, type, method, and
so on. This can include information required for debugging and
garbage collection, as well as security attributes,
marshalling data, extended class and member definitions,
version binding, and other information required by the runtime.
- module
- A loadable unit, which can contain type declarations and type implementations.
The module contains enough information to enable the runtime to locate
all implementation parts when the module is loaded. The format for modules
is an extension of the Windows portable executable
(PE) file format. When deployed, a module is always contained in
an assembly.
- monitor
- Typically, a monitor is the sole and primary
display device for a PC.
Monitors have traditionally been constructed using
analog CRT technology, however, have recently
been constructed using digital
PDP (plasma) and LCD display technologies.
Computer monitors are designed for RGB signals. When
using a display device as a computer monitor, the image will always
look best when displayed using the RGB source input and with the resolution
output of the computer graphic card set to the resolution of the display
device.
- MSIL
- Microsoft Intermediate Language – a language used as the output
of a number of compilers and as the input to a
JIT compiler. The runtime includes several
JIT compilers for converting MSIL to native code.
- namespace
- A logical naming scheme for grouping related types. For example,
the .NET Framework uses a hierarchical
naming scheme for grouping types into logical categories of related
functionality, such as ASP.NET application framework,
or remoting functionality. Design tools can
use namespaces to make it easier for developers to browse and reference
types in their code. The concept of a namespace is orthogonal to that
of an assembly: a single assembly can contain
types whose hierarchical names have different namespace roots, and a
logical namespace root can span multiple assemblies. In the .NET Framework,
a namespace is a logical design-time naming convenience, whereas an
assembly establishes the name scope for types at run time.
- native code
- Code that has been compiled to processor-specific machine code.
- .NET
- (pronounced dot NET) Microsoft's 32-bit based software development
solution for the next generation of micro-processing hardware to replace

a faster (and more powerful) development and operating environment.
See .NET Framework.
- .NET data provider
- A component of ADO.NET that provides access
to data from a relational database.
- .NET Framework
- A platform for building, deploying, and running Web Services and
applications. It provides a highly productive, standards-based, multi-language
environment for integrating existing investments with next generation
applications and services, as well as the agility to solve the challenges
of deployment and operation of Internet-scale applications. The .NET
Framework consists of three main parts: the common language
runtime, a hierarchical set of unified class
libraries, and a componentized version of ASP called
ASP.NET.
- .NET Framework class library

television system standard which displays in a 4:3 aspect ratio, using
525 horizontal scan lines at 60Hz interlaced. Every second line
is refreshed per cyclealternatingto present a complete screen (frame)
refresh every two (60 Hz) cycles, resulting in a frame rate of 30Hz
(frames per second). NTSC is used in Japan, Taiwan, Korea, Philippines,
Pacific Islands, Canada, the United States, Mexico, the Caribbean and
the Americas. NTSC uses FM audio. Compare with PAL.
- OS

data connectivity, communication, and control between
electronic devices such as microprocessors,
memory, disk drives, and data input
and output devices. Compare with DOS and
.Net.

in a 4:3 aspect ratio, using 625 horizontal scan lines at 50Hz interlaced.
Every second line is refreshed per cyclealternatingto present a complete
screen (frame) refresh every two (50 Hz) cycles, resulting in a frame
rate of 25Hz (frames per second). PAL is used in most countries
which don't use NTSC or SECAM, including most of Europe, Asia, Africa,
Oceania, the United Kingdom and Ireland. Compare with
NTSC.

4. In file storage, the route followed by the operating system
in finding, sorting, and retrieving files on a disk.
5. In graphics, an accumulation of line segments or curves to
be filled or overwritten with text.
- PC
- Personal Computer – the original design principle of IBM computers
(of mainframe history) for a small desktop sized (personal) computer
encompassing the principle of individual component construction using
(common) standards for design function and interconnectivity. This future
encompassing concept allowed for the subsequent development of third
party (not IBM) PC hardware and software. This also directly led to
the establishment and subsequent success of Microsoft (who entered into
an initial software OS supply agreement with all IBM
PCs).

any recordable media).
- reference type
- A data type that is stored as a reference to
the value's location. The value of a reference type is the location
of the sequence of bits that represent the type's data. Reference types
can be self-describing types, pointer types, or interface types.
- regular expression
- A concise and flexible notation for finding and replacing patterns
of text. The notation comprises two basic character types: literal (normal)
text characters, which indicate text that must exist in the target string,
and meta-characters, which indicate the text that can vary in the target
string. You can use regular expressions to quickly parse large amounts
of text to find specific character patterns; extract, edit, replace,
or delete text substrings; or to add the extracted strings to a collection
in order to generate a report.
- remoting
- The process of communication between different operating
system processes, regardless of whether they are on the same computer.
The .NET remoting system is an architecture designed
to simplify communication between objects living in different application

with an application. A resource might be displayed in an application
as error messages or as part of the user interface. Resources can contain
data in a number of forms, including strings, images, and persisted
objects.
- RGB
- Red-Green-Blue – the colour combination of light emitting
devices like monitors used
to create any display colour through varying the intensity of each red,
green, or blue element. Can be used to create white colour when all
three are used at their maximum value. RGB is also used to describe
the type of connection between computers and their display devices using
an RGB data cable which carries the signal strength of each individual
RGB element in the image signal. RGB cables are commonly terminated
in a 15 or 9 pin D-Sub type connector. The signal is frequency modulated.
- ROM
- Read Only Memory silicon based microchips
used to permanently store data which retain the
data placed in them even after an external power source to the chip
has been removed. Compare with ROM.
- run-time
- See definition for common language
runtime. Compare with design-time.
- runtime host
- The environment, such as ASP.NET, Internet
Explorer, or the Windows shell, in which the runtime is typically started
and managed. Runtime hosts create application domains in which to run
managed code on behalf of the user.
- SCADA
- Supervisory Control and Data Acquisition – an industry-standard
term that is used to describe any system or tool that monitors and collects
data for a production or manufacturing process.
SCADA systems provide a high level of supervision enabling operators
to monitor activities of the production process and influence them accordingly,
to maximise production levels.
- Schema
- A description of the organisation or structure of a data source.
In a SCADA data source, the term schema refers to the list of Tags,
Alarms and Trends that the database contains. In a relational database
it refers to a list of tables and views and their structure.
- serial communications
- A communications method which transmits data one bit at a time.
Compare with parallel communications.
- serial cable
- A cable that connects to a serial port.
It is used to transfer information between two devices.
- serial port
- An input/output location (channel) that sends and receives data
to and from a computer or a communications device one bit at a time.
Serial ports are used for serial data
communication and as interfaces to peripheral devices, such as mouse
devices printers, PLCs, etc. Compare with parallel
port.
- server
- 1. On a local area network (LAN), a computer running administrative
software that controls access to the network and its resources, such
as printers and disk drives, and provides resources to computers functioning
as workstations on the network.
2. An application that responds to requests from another application
or task. See also client.
- service
- A Windows service is a program, routine, or process that performs
a specific system function to support other programs, particularly low-level
system operations. A network service is an application that makes data
or operations available to network clients. Services are generally non-interactive
(with no user interface) and run in the background. Typically, Windows
services are started automatically with the start-up of the operating
system.
- SGML
- Standard Generalized Markup Language – an information-management
standard adopted by the International Organization for Standardization
(ISO) in 1986 as a means of providing platform-independent and application-independent
documents that retain formatting, indexing, and linked information.
SGML provides a grammar-like mechanism for users to define the structure
of their documents and the tags they will use to denote the structure
in individual documents. Both XML and
HTML are derived from SGML.
- SOAP
- Simple Object Access Protocol – a simple, XML-based
protocol for exchanging structured and type information on the Web.
The protocol contains no application or transport semantics, which makes
it highly modular and extensible.
- SPC
- Statistical Process Control – is a set of mathematical tools used
to determine and monitor the level of statistical control demonstrated
by your production process.
SPC will show the capability of the process to:
- Produce within tolerance i.e. is the variability of the product greater
than the range between specification limits?
- Produce within specification i.e. does the distribution of the product
extend beyond either or both of the specification limits and by what
percentage of production?
- SQL
- Structured Query Language – an industry-standard language used to
create databases intended for query-based record retrieval.
- SQL Server
- A customisable file server dedicated to handling
SQL queries. Mainly used as
a common access point for multiple clients to funnel data to and from
an SQL database.
- S-Video
- Short for Super-Video, a technology for transmitting
video signals over a cable by dividing the video information into two
separate signals: one for color (chrominance), and the other
for brightness (luminance). When sent to an analog television,
this produces sharper images than composite video , where
the video information is transmitted as a single signal over one wire.
This is because analog televisions are designed to display separate
Luminance (Y) and Chrominance (C) signals. (The terms Y/C video
and S-Video are the same.)
To use S-Video, the device sending the signals must have an S-Video
output socket, and the device receiving the signals must have an S-Video
input socket. Then you use a special S-Video cable to connect the two
devices.
- Table
- A repository for information in a relational database in a pre-defined
structure.
- TCP/IP
- A protocol developed by the United States
Department of Defense for communications between computers. It is built
into the UNIX system and has become the de facto standard for data transmission
over networks, including the Internet. TCP and IP are transport and
address protocols; TCP is used to establish a connection for data transmission,
and IP defines the method for sending the data in
packets.
- tree
- A hierarchical display of labelled items. The top item in the hierarchy
is called the root. If an item has other items below it in the hierarchy,
it is also referred to as a parent. Items subordinate to parents are
called children. Child items, when displayed, are indented below their
parent item. The hierarchy may be expanded or collapsed at any level
to display or hide child items.
- URL
- Uniform Resource Locator The address of a resource on the Internet.
URL syntax is in the form protocol://host/localinfo, where protocol
specifies the means of returning the object, such as Hypertext Transfer
Protocol (HTTP) or File Transfer Protocol (FTP). Host specifies the remote location where the object
resides, and localinfo is a stringoften a file namepassed to
the protocol handler at the remote location.
- UNC
- The system of naming files among computers on a network so that
a file on a given computer will have the same path when it is accessed
from any of the other computers on the network. For example, if the
directory c:\path1\path2\...pathn on computer server is shared under
the name pathdirs, a user on another computer would open \\servern\pathdirs\filename.ext
to access the file c:\path1\path2\...pathn\filename.ext on server.
- verification
- A part of the compilation process in which code is checked for conformance
to a specific set of rules defined to allow proof of certain security
requirements. The runtime can verify Microsoft Intermediate
Language (MSIL).
- video
- See also S-Video.
- view
- A virtual table generated by a query whose definition is stored
in the database. For example, a view might be defined as containing
three out of five available columns in a table, created to limit access
to certain information. Views can be treated as tables for most database
operations, including Select queries, and under some circumstances,
Update, Insert, and Delete queries. Any operations performed on views
actually affect the data in the table or tables on which the view is
based.
- XML
- Extensible Markup Language a subset of Standard
Generalized Markup Language (SGML) that is optimized for delivery
over the Web. XML provides a uniform method for describing and exchanging
structured data that is independent of applications or vendors.
