LAN (Local Area Network)
A network which is accessible only to its
members, unlike the Internet, which is
open to an unlimited number of people. A
LAN may be built for different purposes.
For example, you can build an office LAN
that is accessible only to members of the
same department or a home LAN that is
accessible only to family members.
TCP/IP (Transmission Control
Protocol/Internet Protocol)
TCP/IP is a networking protocol, a
common set of communications standards
that allow computers to communicate with
each other. Because the Internet uses TCP/
IP, a computer can only connect to the
Internet when the TCP/IP protocol is
installed on it.
