Common gateway interface (CGI)
A set of rules that describe how a Web server communicates with
another application running on the same computer and how the
application (called a CGI program) communicates with the Web server.
Any application can be a CGI program if it handles input and output
according to the CGI standard.
Collision
In an ethernet network, a collision is the result of two devices attempting
to transmit data at exactly the same time. The network detects the
"collision" of the two transmitted packets and discards them both.
Collisions are a natural occurrence on an ethernet network.
Ethernet technology uses carrier sense multiple access/collision detect
(CSMA/CD) to allow devices to take turns using the signal carrier line.
When a device wants to transmit, it checks the signal level of the line to
determine whether another device is already using it. If the line is
already in use, the device waits and tries again, perhaps in a few
seconds. If the line is not in use, the device transmits.
However, two devices can transmit at the same time in which case a
collision occurs and both devices detect it. Each device then waits a
random amount of time and retries until successful in getting the
transmission sent.

Domain name
The location of an organization or other entity on the Internet. For
example, the address www.cobalt.com locates an Internet address for
the domain name "cobalt.com" at a particular IP address and a particular
host server named "www."
