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.
PPPoE (PPP over Ethernet)
PPPoE is a software protocol that uses a
DSL modem to access the Internet.
With PPPoE, the client does not set a
static IP address. Instead, an IP address is
assigned dynamically whenever the client
accesses the Internet.
Protocol
The formal specifications that define the
procedures for computers to follow when
transmitting and receiving data.
TCP/IP (Transmission Control
Protocol/Internet Protocol)
TCP/IP is the network communications
protocol that is used to communicate over
the Internet. TCP is a connection-oriented
protocol for establishing reliable,
sequenced data transfer. TCP ensures that
data reaches its destination.
IP assembles and addresses data packets
for transmission to their network
destinations.

WAN (Wide Area Network)

LANs through the Internet or telephone
lines.

have the same ID and password may log
onto the same wireless LAN for file
sharing.
