Consider a 1Mbps transmission channel. The clock at the receiver has a drift of 1 second in one year. How long a sequence of bits (or frame) can be sent before the clock drift could cause a problem? Assume that the sender and receiver are synchronized at the beginning of each frame and that they cannot resynchronize during the frame. Also, assume that the receiver samples the received signal at the middle of each bit duration to detect if it is 0 or 1.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
