Implementation of data link layer

In a transmission system, any inconvenient may arise such as overflow of data, error, lost or damage frame. Therefore, many functions have been established in order to assure the reliability and efficiency of data transmission. These functions are flow control, error control and error detection which is defined in the Data Link layer.
Many problems have been occurred during the development of networking in the past. Developers kept asking questions during their research to find out the solutions for those problems that they had to face with. They want to know the way how the network handles data. Some of the problems may be about the sender and receiver. The receiver should receive data at an efficient pace that will allow enough time to handle data. Another problem may be about the speed of the network. The total time to transmit data from point A to point B depended on many different factors. Some of these factors that affect the speed are transmission time defined as “the time it...
