Encryption Key
IEEE802.11-compliant security system.
Using the Encryption Key as the
password, only client computers and
Access Points that have the same ID and
password may log onto the same wireless
LAN for file sharing.
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 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)
A network that interconnects remote
LANs through the Internet or telephone
lines.
