typically use a program that uses SMTP for sending e-mail and either POP3 or IMAP for
receiving e-mail.
Subnet Mask
Once a packet has arrived at an organization's gateway or connection point with its unique
network number, it can be routed within the organization's internal gateways using the subnet
number as well. The subnet mask allows router know whether two IP addresses belong to
the same subnet.
TCP/IP
TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet
Protocol (IP) to send data in the form of message units between computers over the Internet.
While IP takes care of handling the actual delivery of the data, TCP takes care of keeping
track of the individual units of data (called packets) that a message is divided into for efficient
routing through the Internet.
WEP
WEP is the short form of Wired Equivalent Privacy. It is a security protocol for wireless local
area networks (WLANs) defined in the 802.11b standard. With less secure physical structure
than LAN, WLANs are more vulnerable to tampering. WEP is to provide security by
encrypting data over radio waves from one end point to another.
