Data transmission standard that provides for up to 33,600 bits per second (bps) communications over telephone lines. It defines a full-duplex (two-way) modulation technique and includes error-correcting and negotiation. See also V.90.
Data transmission standard that provides for up to 56,000 bits per second (bps) communications over telephone lines. The transmission speed from the client-side modem is 33,600 bps, the same as for V.34. The transmission speed from the host-side modem, such as an Internet service provider (ISP) or corporate network, is up to 56,000 bps, with an average speed of 40,000 to 50,000 bps. When the host-side modem does not support this standard, the alternative is V.34. See also client; Internet service provider (ISP); V.34.
The area of the System Monitor graph or histogram display that shows last, average, minimum, and maximum statistics for the selected counter.
In programming, a named storage location capable of containing a certain type of data that can be modified during program execution. See also environment variable.
A font rendered from a mathematical model, in which each character is defined as a set of lines drawn between points. Vector fonts can be cleanly scaled to any size or aspect ratio. See also font.
The part of a TV transmission that is blanked, or left clear of viewable content, to allow time for the TV s electron gun to move from the bottom to the top of the screen as it scans images. This blank area is now being used to broadcast closed captioned and HTML-formatted information.
A format developed by Microsoft for storing video and audio information. Files in this format have an .avi extension. AVI files are limited to 320 x 240 resolution at 30 frames per second, neither of which is adequate for full-screen, full-motion video.
Software for Windows that manages a hardware or software system resource. The middle letter in the abbreviation indicates the type of device; x is used where the type of device is not under discussion.
An IP address that is shared among the hosts of a Network Load Balancing cluster. A Network Load Balancing cluster might also use multiple virtual IP addresses, for example, in a cluster of multihomed Web servers. See also IP address; multihomed computer.
A logical grouping of hosts on one or more LANs that allows communication to occur between hosts as if they were on the same physical LAN. See also local area network (LAN).
Temporary storage used by a computer to run programs that need more memory than it has. For example, programs could have access to 4 gigabytes (GB) of virtual memory on a computer's hard drive, even if the computer has only 32 megabytes (MB) of RAM. The program data that does not currently fit in the computer's memory is saved into paging files. See also paging file; Virtual Memory Size; virtual printer memory.
In Task Manager, the amount of virtual memory, or address space, committed to a process. See also virtual memory.
In a PostScript printer, a part of memory that stores font information. The memory in PostScript printers is divided into two areas: banded memory and virtual memory. The banded memory contains graphics and page-layout information needed to print your documents. The virtual memory contains any font information that is sent to your printer either when you print a document or when you download fonts. See also virtual memory.
The extension of a private network that encompasses encapsulated, encrypted, and authenticated links across shared or public networks. VPN connections can provide remote access and routed connections to private networks over the Internet. See also authentication; encryption; remote access; routing; tunnel.
A program that attempts to spread from computer to computer and either cause damage (by erasing or corrupting data) or annoy users (by printing messages or altering what is displayed on the screen).
Software used to scan for and eradicate computer viruses, worms, and Trojan horses.
A method for sending voice over a LAN, a WAN, or the Internet using TCP/IP packets. See also local area network (LAN); Transmission Control Protocol/Internet Protocol (TCP/IP); wide area network (WAN).
An area of storage on a hard disk. A volume is formatted by using a file system, such as FAT or NTFS, and has a drive letter assigned to it. You can view the contents of a volume by clicking its icon in Windows Explorer or in My Computer. A single hard disk can have multiple volumes, and volumes can also span multiple disks. See also file allocation table (FAT); NTFS file system; simple volume; spanned volume.
System objects in the version of NTFS included with Windows 2000 and Windows XP Professional that represent storage volumes in a persistent, robust manner. Volume mount points allow the operating system to graft the root of a volume onto a directory. See also NTFS file system; volume.
A volume that consists of disk space on one or more physical disks. A volume set is created by using Windows NT 4.0 or earlier. Windows XP Professional does not support volume sets. Instead, you must create a spanned volume on dynamic disks. See also basic disk; dynamic disk; partition; spanned volume; volume.
A volume that represents a duplicate of the original volume taken at the time the copy began. See also differential data; volume.
A tunnel that is initiated by the client. It tunnels PPP over IP from the client to the tunnel server, then the data is forwarded to the target host by the tunnel server. See also client; Internet Protocol (IP); Point-to-Point Protocol (PPP); tunnel; tunnel server.
