This paper will attempt to define and contrast the following terms:
a. Synchronous and asynchronous
b. Analog and digital
c. XON and XOFF
d. Simplex and duplex
e. Serial and parallel transmission
f. Baseband and broadband
g. Serial Line Internet Protocol (SLIP) and Point-to-Point Protocol (PPP)
h. Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP)
i. Transmission Control Protocol (TCP) and Internet Protocol (IP)

Control characters are used when sending data to a printer, monitor, modem, or other device. XOFF (usually referenced by CTRL+S) is used by the transmitting side at the end of the data pulsed to say that the transmission batch is complete. XON (usually referenced by CTRL+Q) is used to start the transmission, and is found at the beginning of the data pulse. (ComputerHope, 2004)

Simplex and duplex
A simplex data transmission is only sent one way and without control characters or error signals. An example of a simplex transmission would be the alarm codes that are sent to officials at a burglar alarm company.
A half- duplex transmission can send a signal and then receive a signal, but cannot send and receive at the same time. An example would be a CB radio that can send a message, and then listen for the response.
A duplex data transmission is capable of sending and receiving data at the same time. A telephone line is an example of a full duplex transmission system. (Eserver, 2004)

Serial and parallel transmission
Serial transmission is the consecutive transmission of the signal. The characters are transmitted in a sequence over a single line, rather than simultaneously over two or more lines, as in parallel transmission.
Parallel transmission are packets of data sent at the same time, usually over more than one transmission line. This results in faster transmission of data. Many times, this data is sent sporadically, and start and stop
