    Appendix F Glossary 10/100 BaseTX An Ethernet connection over twisted-pair cables with a throughput of 10 Mb/s or 100 Mb/s. 10BaseT A 10-Mb/s baseband Ethernet specification using two pairs of twisted-pair cabling (Category 3, 4, or 5): one pair for transmitting data and the other for receiving data.
  • Page 208 Appendix F see Common gateway interface (CGI) Common gateway interface (CGI) A set of rules that describe how a Web server communicates with another application running on the same computer and how the application (called a CGI program) communicates with the Web server. Any application can be a CGI program if it handles input and output according to the CGI standard.
  • Page 209 Glossary Domain Name System (DNS) The Internet service responsible for translating a human-readable host name such as cobalt.com into a numeric IP address (111.123.45.67) for TCP/IP communications. Dynamic Host Configuration Protocol (DHCP) A protocol that provides a mechanism for allocating IP addresses dynamically so that an address can be reused when a host no longer needs it.
  • Page 210 Appendix F HTTP see HyperText Transfer Protocol (HTTP) HyperText Markup Language (HTML) A set of “markup” symbols or tags inserted in a text file intended for display on a World Wide Web browser. The markup tags tell the Web browser how to display a Web page’s content, words, and images. HTML is a subset of Standardized Generalized Markup Language (SGML).
  • Page 211 Glossary Internet domain An Internet domain is a host naming convention used to ensure that no two individual hosts on the global Internet have the same host name. An Internet domain should not be confused with an NT Domain. Internet Message Access Protocol (IMAP) Internet Message Access Protocol is a standard protocol for accessing email from your local server.
  • Page 212 Appendix F IP address A 32-bit address assigned to hosts using Transmission Control Protocol/ Internet Protocol (TCP/IP). An IP address belongs to one of five classes (A, B, C, D or E) and is written as four octets separated by periods (for example, 192.168.10.10), also called the dotted decimal format.
  • Page 213 Glossary Media access control (MAC) address A standardized data-link-layer address that is required for every port or device that connects to a LAN. Other devices in the network use these addresses to locate specific ports in the network, and to create and update routing tables and data structures.
  • Page 214 Appendix F Packet The unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. The packet includes a header containing control information and (usually) user data. Packets are most often used to refer to network layer units of data. see Peripheral Component Interface (PCI) Peripheral Component Interconnect (PCI) Peripheral Component Interconnect (PCI) is an interconnection system...

  • Page 217 Glossary Subnet mask A number that, in conjunction with an IP address, defines the set of IP addresses that are considered “local.” For example, if your IP address is 192.168.25.77 and your subnet mask is 255.255.255.0, then addresses between 192.168.25.1 and 192.168.25.255 are considered local. Also known as netmask.
