Networking Terms
Session
A connection to a network service.
SNMP
Simple Network Management Protocol, allows a TCP/IP host running an SNMP application to
query other nodes for network-related statistics and error conditions. The other hosts, which
provide SNMP agents, respond to these queries and allow a single host to gather network
statistics from many other network nodes.
Source Code
Programs in an uncompiled or unassembled form.
Switch
Multiport Ethernet device designed to increase network performance by allowing only essential
traffic on the attached individual Ethernet segments. Packets are filtered or forwarded based
upon their source and destination addresses.
TCP/IP
Transmission Control Protocol (TCP) and Internet Protocol (IP) are the standard network
protocols in UNIX environments. They are usually implemented, used together, and called
TCP/IP.
Telnet
Telnet is 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 one 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
only.
10Base-T
Ethernet running on 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.
100Base-TX
Specifies 100-Mbps operation using the CSMA/CD protocol over two pairs of category 5 UTP
cable.
Terminal Server
A concentrator that facilitates communication between hosts and terminals.
TFTP
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.
Throughput
The amount of data transmitted between two points in a given amount of time, e.g., 10 Mbps.
