Wildcards

2011-11-03T12:13:00.000-07:00

A keyboard character that represents one or more characters in a string, usually for specifying more than one file by name. The question mark (?) matches any character in a specified position, and the asterisk (*) matches any number of characters up to the end of the filename or extension.

Warm Boot

2011-11-03T12:12:00.000-07:00

The process of restarting a computer that is already running by holding down the Ctrl, Alt, and Delete keys simultaneously. It can also refer to choosing a Shut Down And Restart option in Microsoft Windows 9x or Windows NT.

WAN (Wide Area Network)

2011-10-30T12:40:00.000-07:00

A network that spans a large geographical area. The network is connected by means of telephone lines, ISDN (Integrated Services Digital Network) lines, DSL, cable, radio waves, or satellite links.

Define Volts

2011-10-30T12:39:00.000-07:00

The unit of electromotive force, or the potential energy, that will produce a current of 1 ampere when steadily applied against a resistance of 1 ohm. Voltage is also considered the potential energy of a circuit.

Virtual Memory

2011-10-30T12:36:00.001-07:00

Hard disk space that can be used as additional memory for holding data not immediately required by the processor.

Virtual Control Program Interface (VCPI)

2011-10-30T12:35:00.000-07:00

A memory management specification that accesses extended memory for MS-DOS-based applications. It allows only one application to control extended memory and does not support multi-tasking. Windows is not compatible with the VCPI specification.

VGA (Video Graphics Array)

2011-10-27T11:45:00.000-07:00

A graphics adapter that offers 16 colors at a resolution of 640 pixels × 480 pixels. To gain more colors, VGA uses an analog video signal instead of a digital signal. With the analog signal, the VGA standard is able to provide 64 distinct levels for each color, giving users 643 or 262,144 possible colors. It uses a 15-pin, three-row, female DB-type connector.

Vertical Refresh Rate (VRR)

2011-10-27T11:40:00.000-07:00

The speed at which a monitor completes all vertical traces.

Usenet

2011-10-27T11:39:00.000-07:00

The vast collection of discussion groups and newsgroups on the Internet.

USB (Universal Serial Bus)

2011-10-27T11:38:00.000-07:00

A new external expansion bus that is popular for use with low-speed mass storage devices such as Zip drives, modems, and printers.

UPS (Uninterruptible Power Supply)

2011-10-26T13:40:00.000-07:00

Acts as both a surge suppressor and a power leveler to provide the computer with a constant source of power. It also provides power during a power failure or interruption so the user can safely save data before shutting down.

Upload

2011-10-26T13:37:00.000-07:00

The ability to transfer (send) a file from one computer to a remote computer.

UMB (upper memory block)

2011-10-26T13:35:00.000-07:00

Unused spaces in upper memory that can be divided into blocks. These empty blocks have no RAM associated with them and are simply reserved space. This unused space is valuable because, unlike expanded and extended memory, MS-DOS can run programs in UMB.

UMA (Upper Memory Area)

2011-10-26T13:30:00.000-07:00

The area from 640 KB to 1024 KB that is designated for hardware needs such as video RAM, BIOS, and memory-mapped hardware.

Twisted-pair Cable

2011-10-23T06:28:00.000-07:00

Consists of two insulated wires twisted around each other to form a pair. One or more twisted pairs are used in a twisted-pair cable.

TSR (terminate-and-stay-resident program)

2011-10-23T06:27:00.000-07:00

A computer program, also known as a memory-resident program, that remains in memory after being run so that it can be called up later. These extend the capabilities of the operating system or provide "pop-up" functions (such as a calendar or calculator) that can be brought up in the middle of another program without disturbing that program. These programs were popular in the days of MS-DOS, but lead to numerous problems due to memory usage conflicts.

Transistor

2011-10-23T06:25:00.000-07:00

An electronic device that allows a small current in one place to control a larger current in another place; commonly used as amplifiers in radio and audio circuits.

Topology

2011-10-22T11:20:00.000-07:00

The layout scheme that describes the way in which network nodes are wired in relation to each other.

Define Telnet

2011-10-22T11:18:00.000-07:00

A terminal emulation program that allows you to log on to another computer system over the Internet. You can then run programs on that machine as though you dialed in directly.

Telecommunications

2011-10-22T11:17:00.001-07:00

The ability to transmit data over telephone lines to a remote computer.

Telecom Software

2011-10-22T11:15:00.000-07:00
