Computer Communications & Networks

The devices are called end devices or more correctly hosts; which are either the destinations or sources of information transmitted via a network so accessing a network or site remotely involves three elements; a source or sender, a destination and a medium which is the channel through which the data is transmitted. The data transmitted can be in the form of text, graphics, voice or video which are converted into a language the computer understands called binary bits (data is transmitted as a zero or a one: 0I). The bits are then ‘programmed’ or coded into signals or data packets that can be transmitted through a medium over a network. Now sending data as one continuous stream will mean that no other data or devices can use the medium while the data is being transmitted just like a pipeline; if it is delivering gasoline, it cannot at the same time deliver liquid petroleum gas; so the data is broken into smaller packets; a process called segmentation which allows many different data to be transmitted concurrently, this is called multiplexing and segmenting data enhances network reliability so data is not lost easily whenever a break in communication occurs (“3rd Symposium on Networked Systems design and Implementation (NSDI’06), San Jose, California”). ...Show more
