Authentication
The process whereby a user or information source proves they are who they
claim to be; in other words, the process of verifying the identity of a user,
device or other entity in a computer system, often as a prerequisite to
allowing access to resources in a system. Authentication is any technique
enabling the receiver to automatically identify and reject messages that have
been altered either deliberately or by channel errors.
See also Encryption and Secure Sockets Layer (SSL).
Authentication Post Office Protocol (APOP)
Authentication POP is a challenge-response authentication scheme built on
top of the standard POP protocol. APOP is designed in a way that protects
your password from being sent across the network. To keep your password
safe, the server stores your password in a file on local disk drive. When your
mail client connects to the APOP server, a magic string is sent back. That
string contains a unique identifier for the current session based upon the
process id (PID) and current time.
Carrier sense
In a local area network (LAN), an ongoing activity of a data station to detect
whether another station is transmitting.
Carrier sense multiple access with collision detection (CSMA/CD)
A protocol that requires carrier sense and in which a transmitting data station
that detects another signal while transmitting stops sending, sends a jam
signal and then waits for a variable period of time before sending again.
Used in ethernet LAN technology.
CGI
See Common gateway interface (CGI).
