Appendix A: Terms and Glossary
TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP was originally developed by the Defense Department of the US to allow
dissimilar computers to talk. Today, as many of us know, this protocol is used as
the basis for the Internet. Because it must span such a large distance and cross
multiple, smaller networks, TCP/IP is a routable protocol, meaning it can send
data through a router on its way to its destination. In the long run, this slows
things down a little, but this ability makes it very flexible for large networks
DHCP (Dynamic Host Configuration Protocol)
It’s a method for assigning a permanent Internet Protocol (IP) addresses or on the
fly to individual computers in an organization’s network. Usually is performed by
a DHCP server.
FTP (File Transfer Protocol)
This is a method of moving files from system to system using TCP/IP with FTP
application.
DHCP IP
A dynamic IP address is assigned to your computer by your ISP’s server so that
other computer servers can find your computer when you are connected to the
Internet. This IP address changes because whatever your computer reconnects
to the Internet, a different IP address will be assigned to your machine.
Static IP
It is an IP address assigned to your computer permanently. It’s a series of digits
used to identify your computer and looks something like this: 185.182.12.4
PPPoE (Point-to-Point Protocol over Ethernet)
The Point-to-Point Protocol over Ethernet (PPPoE) feature allows a PPP session to
be initiated on a simple bridging Ethernet connected to the client. The session is
transported over the ATM link via encapsulated Ethernet-bridged frames. The
session can e terminated at either a local exchange carrier central office or an
Internet service provider (ISP) point of presence.
