Firmware. Software that has been has been permanently or semi-permanently written
onto ROM. Your ProxyServer supports flash ROM which means you can upgrade the
fimware in the ProxyServer very easily by obtaining a copy of the new firmware and
using the upgrade firmware function.
FTP (File Transfer Protocol). A protocol which allows a user on one host to access, and
transfer files to and from, another host over a network.
Intranet. The Intranet is the use of Internet technologies within a company. Intranets
exist only within organizations while the Internet is a global network open to all. Intranets
run on private networks within companies and between their branch offices.
IP (Internet Protocol). The Internet Protocol is the network layer for the TCP/IP Protocol
Suite. It is a connectionless, best-effort packet switching protocol.
IP Addresses (Referenced from www.pcwebopedia.com)
A Computer on the Internet is identified by it’s IP Address. A computer’s IP address is
like a telephone number because it identifies one address or in this case one computer
Device. Every computer or device on a network must have a different IP address. An IP
address consists of four groups of numbers called octets which are separated by
periods. For example, 213 .0 .0.1 is an IP address. An IP address consists of a network
portion and a host portion. The network portion identifies the subnet that the computer
belongs to. The host portion identifies the particular computer or node on that network. In
our example IP address, 213 . 0 . 0 . 1 refers to the network 213 . 0 . 0 with the computer
number 1. IP addresses can either be dynamic (temporary) or static (permanent, fixed). A
dynamic IP address is a temporary IP address that is assigned to you by a server
(Usually a DHCP server) when you turn on your computer. A static IP address is a
permanent IP address that you can set yourself in your computer. When the ProxyServer
dials-up your ISP your ISP can give it a fixed or dynamic IP address. Likewise when you
turn on your computer the ProxyServer can give your computer a dynamic or fixed IP
address.
ISDN TA. (Integrated Services Digital Network Terminal Adapter) ISDN is a high speed
digital telephone connection involving the digitization of the telephone network using
existing wiring. An ISDN Terminal Adapter can be though of like an “ISDN Modem”.
ISP (Internet Service Provider). An organization that provides Internet services. An ISP
is the company that will provide the connection from your computer or network to the
Internet. An ISP can offer a range of services, such as dial-up accounts, E-mail, web
hosting or News.
LAN (Local Area Network). A data network intended to serve an area of only a few
square kilometers or less. This often means a small private network in companies.
ML-PPP (Also called MP or MPPP) stands for Multilink Point to Point Protocol and is an
advancement of the PPP protocol that allows for the bridging or bundling of two ISDN or
analog channels for faster connections. What does that mean in practical terms? It
means that you can use one computer to use two or more modems to download a single
web page. For example, if I’m trying to access www.yahoo.com using two modems,
each modem will go get part of Yahoo, then your ProxyServer will bundle the information
together and then give it to your computer resulting in double the speed.
MAC address. The hardware address of a Device connected to a shared media. To find
out the MAC address of your computer please see Chapter 6 - Troubleshooting : Tool
