b-node
A NetBIOS implementation that uses broadcast NetBIOS name queries for name registration and resolution. See also network basic input/output system (NetBIOS).
backup domain controller (BDC)
A domain controller running Windows NT Server 4.0 or earlier that receives a read-only copy of the directory database for the domain. The directory database contains all account and security policy information for the domain. See also Active Directory; primary domain controller (PDC).
Backup Operators group
A type of local or global group that contains the user rights you need to back up and restore files and folders. Members of the Backup Operators group can back up and restore files and folders regardless of ownership, permissions, encryption, or auditing settings. See also auditing; global group; local group.
backup set
A collection of files, folders, and other data that has been backed up and stored in a file or on one or more tapes.
baseline
A range of measurements derived from performance monitoring that represents acceptable performance under typical operating conditions.
Basic authentication
An authentication mechanism that is supported by most browsers, including Internet Explorer. Basic authentication encodes user name and password data before transmitting it over the network. Note that encoding is not the same as encryption . Also known as plaintext authentication . See also Anonymous authentication; Digest authentication.
basic input/output system (BIOS)
On x86-based computers, the set of essential software routines that test hardware at startup, start the operating system, and support the transfer of data among hardware devices. The BIOS is stored in read-only memory (ROM) so that it can be executed when you turn on the computer. Although critical to performance, the BIOS is usually invisible to computer users.
bootable CD
A CD-ROM that can be used to start a computer. An automated installation uses a bootable CD to start a computer. See also automated installation.
BOOTP
See definition for bootstrap protocol (BOOTP).
bootstrap protocol (BOOTP)
A protocol used primarily on TCP/IP networks to configure diskless workstations. RFCs 951 and 1542 define this protocol. DHCP is a later boot configuration protocol that uses this protocol. The Microsoft DHCP service provides limited support for BOOTP service. See also Dynamic Host Configuration Protocol (DHCP); Transmission Control Protocol/Internet Protocol (TCP/IP).
bottleneck
A condition, usually involving a hardware resource, that causes a computer to perform poorly.
browser
Software that interprets the markup of files in HTML, formats them into Web pages, and displays them to the end user. Some browsers also permit end users to send and receive e-mail, read newsgroups, and play sound or video files embedded in Web documents.
built-in groups
The default security groups installed with the operating system. Built-in groups have been granted useful collections of rights and built-in abilities .
In most cases, built-in groups provide all the capabilities needed by a particular user. For example, members of the built-in Backup Operators group can back up and restore files and folders. To provide a needed set of capabilities to a user account, assign it to the appropriate built-in group.
See also group.
