- GLOSSARY:
-
- 56K Leased Line
- A digital, dedicated 64 kbps circuit with 8kbps used for
- signaling. Sometimes called DDS or ADN.
-
- Archie
- A search mechanism that works in conjunction with anonymous FTP
- archives, allowing users to search for files on multiple anonymous
- FTP archives.
-
- Channel Service Unit/Digital Service Unit (CSU/DSU)
- Connects to the Telephone Company "channel" (56K or T1) and
- provides a connection to network equipment such as a router.
-
- Dedicated Line
- A permanently connected private telephone line between two
- locations. Leased lines are typically used to connect a local area
- network to an Internet service provider.
-
- Dialup Line
- A method of connecting to a computer by calling it up on the
- telephone. This is typically the same type of line used to place
- normal voice telephone calls.
-
- Domain Name System (DNS)
- A distributed database system for translating computer names into
- numeric Internet addresses, and vice-versa. DNS allows access to
- the Internet using more easily remembered names as opposed to
- cryptic numbers.
-
- Gopher
- A protocol developed at the University of Minnesota that provides
- for unified presentation of Internet services such as WAIS, Telnet,
- and FTP. Gopher is a distributed document retrieval system which
- retrieves information based on user requests
-
- FOSSIL Driver
- A set of interface routines written for the IBM PC's serial port,
- in order to compensate for the lack of decent ROM BIOS support for
- serial communications on the IBM PC. Stands for "Fido/Opus/SEAdog
- Standard Interface Layer."
-
- FTP
- File Transfer Protocol. FTP is a machine and operating system
- independent protocol for the exchange of files that is very popular
- among machines connected to the Internet.
-
- Internet Protocol (IP)
- The most important protocol on which the Internet is based. It
- allows a packet to traverse multiple networks on the way to its
- final destination.
-
- IP Address
- A unique Internet Protocol identifier given to each computer on
- your local area network that allows it to be addressed over the
- Internet.
-
- Leased Line
- See dedicated line.
-
- Netware, Novell
- A dedicated server based product from Novell for sharing data over
- a local area network.
-
- Netware Loadable Module (NLM)
- A software program that runs directly on a Novell Netware server.
- Once running, the program becomes a functional part of the server.
-
- Packet
- A bundle of data. On the Internet data is broken into small
- chunks, called "packets"; each packet traverses the network
- independently.
-
- Point of Presence (POP)
- The closest location for a network or telephone company. Vendors
- will charge you based on how far you are from their local POP.
-
- Point to Point Protocol (PPP)
- PPP is a multiprotocol standard defined in RFC 1171 which provides
- for the transmission of packets over serial lines. Since PPP is
- more complex than SLIP, it has not been as widely implemented.
-
- Protocol
- A definition for how computers will act when talking to each other.
- Standard protocols allow computers from different manufacturers to
- communicate; the computers can use totally different software,
- providing that the programs running on both ends agree on what the
- data means.
-
- Request For Comments (RFC)
- A set of papers in which the Internet's standards, proposed
- standards and generally agreed-upon ideas are documented and
- published.
-
- Router
- A device that connects two or more networks, also called a gateway
- in TCP/IP terminology. Routers typically have a TCP/IP address for
- each physical medium to which they are linked. A router connected
- to a SLIP link as well as an Ethernet would have two TCP/IP
- addresses. Routers function based on information in their routing
- tables, which can be configured statically (common for BBSs) or
- dynamically via routing protocols.
-
- Serial Line Internet Protocol (SLIP)
- SLIP is a simple "nonstandard" for transmission of Internet
- Protocol datagrams over serial lines. Since SLIP is a simple
- protocol by nature, it is easy to implement and widely available.
- It does not provide error correction or negotiation of connection
- characteristics; such features are provided for in Point to Point
- Protocol (PPP).
-
- Simple Mail Transfer Protocol (SMTP)
- The Internet standard for the exchange of electronic mail messages.
-
- T1 Leased Line
- A dedicated line that provides 1.544 mbps service.
-
- Transmission Control Protocol (TCP)
- One of the protocols on which the Internet is based. TCP is a
- connection oriented reliable protocol.
-
- Transmission Control Protocol/Internet Protocol (TCP/IP)
- see Transmission Control Protocol and Internet Protocol
-
- Terminal Server
- Created to allow for simultaneous logins to a TCP/IP-based network,
- terminal servers have become increasingly sophisticated devices,
- recently adding support for SLIP and PPP. In their simplest form,
- a terminal server accepts connections from serial devices such as
- modems and allows those devices to communicate with a network.
-
- Telnet
- The Internet standard for remote login, is and application protocol
- that runs on top of TCP/IP. In short, telnet allows you to use
- your local keyboard and monitor to control authorized actions on a
- remote machine.
