Client
A computer system or process that requests a service from another computer
system or process (a "server"). Typically, a client is an application that runs on a
personal computer or workstation and relies on a server to perform some
operations.
Collision
In Ethernet, a collision occurs as the result of two nodes transmitting
simultaneously. The frames from each device impact and are damaged from the
impact.
CRC
Cyclic Redundancy Check. A data transmission error-checking technique in which
the frame recipient calculates a remainder by dividing frame contents by a prime
binary divisor and compares the calculated remainder to a value stored in the frame
by the sending node.
CSMA/CD
Carrier Sense Multiple Access with Collision Detection. A multi-user network
allocation procedure in which every station can receive the transmissions of all
others. Each station waits for the network to be idle before transmitting and each
station can detect collisions by other stations.
Data Link Layer
Layer 2 of the OSI reference model. The Data Link Layer is responsible for physical
addressing, network topology, line discipline, error notification, ordered delivery of
frames, and flow control.
DHCP
Dynamic Host Configuration Protocol. A protocol for assigning dynamic IP
addresses to network devices. With dynamic addressing, a device can have a
different IP address every time it connects to the network. In some systems, the
device's IP address can even change while it is still connected. DHCP also supports
a mix of static and dynamic IP addresses.
Domain
A group of computers and devices on a network that are administered as a unit with
common rules and procedures.
