Even Parity : The sending computer counts the 1's in the data part of the packet ; if the number of 1's is even, the Parity bit is 0 this makes the total number of bits even. Odd parity : This works on exactly the same way as even parity except that the total number of bits must be Odd.

Synchronous Communication sends data blocks at strictly timed intervals that are monitored at both ends. Modems operating at speeds up to 56kbps over standard telephone audio lines are usually synchronous devices.

Asynchronous &is any data transmission that does not link the two devices with a common data clock. A Signal called a start bit is sent at the beginning of each segment, & a signal called a stop bit is sent at the end, these let the receiving device note the baundries(beginning & end) of a transmission packet. Early PC modems were almost Asynchronous devices operating at speeds of no more than 18,000 bps.

A computer/modem/software combination that manages Internet traffic to and from a LAN. A proxy server can provide other features, such as document caching & asses control.

Protocol is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols exist at several levels in a telecommunication connection. On the Internet, there are the TCP/IP protocols, consisting of: Transmission Control Protocol(TCP), which uses a set of rules to exchange messages with other Internet points at the information packet level Internet Protocol(IP), which uses a set of rules to send and receive messages at the Internet address level Additional protocols that include the Hyper Text Transfer Protocol (HTTP) an d File transfer Protocol (FTP), each with defined sets of rules to use with corresponding programs elsewhere on the Internet.

POTS stands for "Plain Old Telephone Service" A common term that donates the basic analog phone network as compared to newer digital networks used for packet transfer of data.
