- checksum
- Many communications protocols, including TCP, UDP, and IP feature a mathematical error-detection mechanism known as a checksum. Essentially, a mathematical process is performed at the source machine using the payload data as input. The output of that process is stored in the checksum field of the protocol's header. The receiving machine performs the same process and compares its results with the results stored in the header. If the two match, it is relatively safe to assume that the payload has not been damaged in transit.
- CIDR
- Classless Interdomain Routing, or CIDR (pronounced cider as in the apple juice drink), is the system that is currently in use for IP addressing. CIDR enables you to define a network address at any bit in the 32-bit address. Previously, boundaries between the network and host address were limited to every 8th bit.
