A Glossary of Intranet Terms

BOOTP - Bootstrap Protocol - A protocol that allows a machine to get its IP address dynamically.

DHCP - Dynamic Host Configuration System. Based on BOOTP this protocol also provides for dynamic address allocation in assigning IP address to workstations on a network.

DNS - Domain Naming System. This application maps IP addresses to the names assigned to machines on a network.

FTP - File Transfer Protocol. This protocol allows files to be downloaded/uploaded between TCP/IP sites.

HTML - Hypertext Markup Language. A subset of Standard Generalized Markup Language that creates platform-independent documents with hypertext links.

SMTP - Simple Mail Transfer Protocol. A TCP/IP-based messaging system for e-mail.

TCP/IP - Transmission Control Protocol/Internet Protocol. The underlying protocol of the Internet originally developed under contract with the Defense Department.TCP - A transport protocol that verifies that data is delivered accurately and in the proper sequence from sender to receiver.IP - This protocol defines datagrams the fundamental unit of transmission in the Internet. It also establishes the Internet addressing mechanism.

Telnet - This application provides for terminal emulation and host computer access.

UDP - User Datagram Protocol. This is TCP/IP's secondary transport mechanism which does not provide TCP's sender-to-receiver accuracy checks.
