Access Methods

The Function of Access Methods

Traffic Control on the Cable
Multiple computers must share access to the cable that connects them. However, if two computers were to put data onto the cable at the same time, the data packets from one computer would collide with the packets from the other computer, and both sets of data packets would be destroyed. Figure 3.1 shows what happens when two computers try to access the network at the same time.

If data is to be sent over the network from one user to another, or accessed from a server, there must be some way for the data to access the cable without running into other data. And the receiving computer must have reasonable assurance that the data has not been destroyed in a data collision during transmission.
