A synchronous data transfer is displace in a continuous, single stream of characters, grouped into buffered bits. onward the transmission is sent, synchronous characters are sent that set the sending and the receiving ends to the same time. Once affirmation of the syn pulse is returned, the stream is sent to the receiving end. An asynchronous data transfer consists of start and stop bits at the get down and the end of the pulses that are sent. (Modem, 2004)Analog and digitalAn analog signal is an exact replica of the fit or read being transmitted. An analog wave signal is a signal that consists of changing amplitudes of frequencies. An analog transmission is used oer telephone lines to transmit voice frequencies over a carrier frequency through the telephone line. An electric current reproduces the frequency for transmission, then it is converted at the other end back into the sound wave.A digital signal is a square wave signal consisting of a voltage and then a lack of voltage. Digital transmission involves laser lights that flash on and off and are carried through fiber optic lines. This is a very fast transmission rate (approximately 450 flashes per second) and can result in two fiber optic transmission lines to be able to transmit almost 15,000 conversations at the same time. Digital transmission is faster than analog, and also is to a greater extent stable, as less noise or other interference can disrupt ... ...es non really say such about what happen here, pretermit to point out that the host has draw to the communicate using some protocol so it can transmit IP packets over it. This protocol is not specified and varies from host to host and network to network. From http//www.buzzle.com/editorials/text8-24-2004-58325.aspReferencesComputerHope.

A synchronous data transfer is sent in a continuous, single stream of characters, grouped into buffered bits. Before the transmission is sent, synchronous characters are sent that set the sending and the receiving ends to the same time. Once affirmation of the syn pulse is returned, the stream is sent to the receiving end. An asynchronous data transfer consists of start and stop bits at the beginning and the end of the pulses that are sent.
