In this second case, the gateway host would be used-if it had not been defined, the connect attempt would fail. If the subnet mask is not set explicitly with the Set/Define Server Subnet Mask command, the Server will assume a mask based on its IP address and thus the apparent network type. This mask will be 255.255.255.0 for most 19x.x.x.x and 2xx.x.x.x IP addresses. A point on the network backbone where other devices can be attached. If the network is thought of as a freeway, the taps on the network are the on and off ramps to the freeway (and like freeway access ramps, taps are usually where network problems occur). Taps may be of several types, including simple "T" connectors or "Vampire" taps that attach directly to a network cable. The standard network protocols in UNIX environments. They are almost always implemented and used together. TCP/IP is an extremely flexible protocol, allowing reliable access to over four billion possible nodes anywhere in the world. It also allows many protocols to run on top of it, notably Telnet, Rlogin, and TFTP. TCP/IP support may be integral to an operating system, as in UNIX, or it can be a separate product added later as on VMS machines. An application that provides a terminal interface between hosts using the TCP/ IP network protocol. It has been standardized so that Telnetting to any host should give you an interactive terminal session, regardless of the remote host type or operating system. Note that this is very different from the LAT software, which allows only local network access to LAT hosts. Thinwire network cable. Thickwire network cable. Fast Ethernet cable. It is similar physically to 10BASE-T, but capable of higher speeds. Ethernet running across Unshielded Twisted Pair (UTP) cable. Note that 10BASE-T is a point-to-point network media, with one end of the cable typically going to a repeater/hub and the other to the network device. Trivial File Transfer Protocol. On computers that run the TCP/IP networking software, TFTP is used to quickly send files across the network with fewer security features than FTP. TFTP is used by the Server to download a boot file in the UNIX environment. One of the major varieties of Ethernet cabling. Thickwire network cable is 1/ 2" diameter coax cable. It is generally found on larger networks where a cable may travel for long distances and usually connects multi-user computers to the network. It is harder to work with than Thinwire cable, but offers better noise and error protection and can be run much farther (up to 500m/1500 ft. without repeaters). Connections to Thickwire networks are usually made with 15-pin connectors. Glossary-7

Telnet
An application that provides a terminal interface between hosts using the
TCP/
IP
network protocol. It has been standardized so that Telnetting to any host
should give you an interactive terminal session, regardless of the remote host
type or operating system. Note that this is very different from the

higher speeds.
10BASE-T

10BASE-T is a point-to-point network media, with one end of the cable
