Ethernet
Ethernet is the most widely-installed local area network (LAN)
technology. Specified as IEEE 802.3.
Fast Ethernet
Fast Ethernet or 100BASE-T provides transmission speeds up to 100
megabits per second and is typically used for LAN backbone systems.
Firewall
firewall is a set of related programs, located on a network gateway
server, that protects the resources of a private network from users from
other networks. (The term also implies the security policy that is used
with the programs.) An enterprise with an Intranet that allows its
workers access to the wider Internet installs a firewall to prevent
outsiders from accessing its own private data resources and for
controlling what outside resources its own users have access to.
FTP (File Transfer Protocol)
File Transfer Protocol (FTP), a standard Internet protocol, is the simplest
way to exchange files between computers on the Internet.
Gateway
A gateway is a network point that acts as an entrance to another
network. On the Internet, a node or stopping point can be either a
gateway node or a host (end-point) node.
Internet
Internet, sometimes called simply "the Net," is a worldwide system of
computer networks - a network of networks in which users at any one
computer can, if they have permission, get information from any other
computer (and sometimes talk directly to users at other computers).
IP Address
The Internet is really the interconnection of many individual networks
(it's sometimes referred to as an internetwork). So the Internet Protocol
(IP) is basically the set of rules for one network communicating with any
other (or occasionally, for broadcast messages to all other networks).
Each network must know its own address on the Internet and that of
any other networks with which it communicates. To be part of the
Internet, an organization needs an Internet network number, which it
can request from the Network Information Center (NIC). This unique
network number is included in any packet sent out of the network onto
the Internet.
LAN (Local Area Network)
Local area network (LAN) is a group of computers and associated devices
that share a common communication line or wireless link and typically
shares the resources of a single processor or server within a small
geographic area (for example, within an office building). Usually, the
server has applications and data storage that is shared in common by
multiple computer users. A local area network may serve as few as two or
three users (for example, in a home network) or as many as thousands of
users (for example, in an FDDI network).
