U
1. ULSI (Ultra Large Scale Integration )
Integration of about ten million electronic components on a single chip.
2. UVEPROM (Ultra Violet EPROM)
An EPROM chip in which stored information is erased by exposing the chip for some time to ultraviolet light. .
3. Unbundled
Application software priced separately from hardware.
4. Unconditional branch statement
A branch statement that causes alteration in sequential flow of execution of a program without any condition test (such as go to statement).
5. Unconditional transfer
A program instruction that causes program control to flow out of normal sequence unconditionally.
6. Unicode
A universal character-encoding standard used for representation of text for computer processing. It provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language. It has the capacity to encode as many as a million characters.
7. URL (Uniform Resource Locator)
An addressing scheme used by WWW browsers to locate sites on the Internet.
8. UPS (Uninterrupted Power Supply)
A battery- supported power unit between an external power source and a computer system. It supplies clean and continuous power even during power failures.
9. Universal gate
A logic gate that is alone sufficient to implement any Boolean function. For example, NAND and NOR gates.
10. UPC (Universal Product Code)
A universal or standardized optical bar code that normally appears on retail packages, and is read by a laser beam scanner.
11. UDT (User Defined Data Type)
A composite data type whose composition is not included in language specification. A programmer declares it in a program where it is used.
12. USB (Universal Serial Bus)
It is used for connecting peripherals to PC (upto 127) off of a single port with the devices in a daisy chain.
V
1. VSNL
Videsh Sanchar Nigam Limited
2. VLSI (Very Large Scale Integration)
An electronic circuit with about 10,000 transistors fabricated on a single silicon chip.
3. VSAT (Very Small Aperture Terminals)
Smaller disk antennas having lower power transmitters and receivers, which can be installed at users sites. It enables a large number of users to benefit from satellite communication.
4. Volatile storage
A storage medium that loses its contents when power fails, or when power is switched off.
5. VAN (Value Added Network)
Some companies specialize in providing value added data transmission service. Value added over and above the standard services of common carriers may include electronic mail, data encryption/decryption, access to commercial databases and code conversion for communication between incompatible computer. These companies normally take dedicated lines of a common carrier on long term lease, do value addition to enhance communication facilities and then sell the enhanced service to users. This type of service is known as value added network service.
6. Veronica
Veronica is a tool to find information on a Gopher site via specified keywords supplied by the user. Veronica actually stands for very easy rodent oriented net wide index to computerized archives.
7. VESA (Video Electronics Standards Association )
It is responsible for graphics and local bus standards.
8. VGA (Visual Graphics array video adaptor)
It was introduced by IBM in 1987. A VGA monitor can display 640 X 480 pixels using 16 different colours or 320X200 pixels using 256 colours. These colours. These colours can be chosen from a table of upto 262,144 colours.
