Download file to see previous pages The motivation behind the creation of communication systems is due to the need for the improvement of transmission reliability. This is due to the reduction of errors in the process of sending and the reception of messages. Communications systems also increase the transmission capacity with the ability of sending large sizes of data in a single mode for a short time. In order to enable the exchange of information, there must be the transmission of the information from different devices, through a communication channel. There exists different communication media such as optical fiber and microwaves that possess unique characteristics for optimum performance. The integration of all the components of information technology forms a communication system (Beavin, p. 12).
There are various requirements for computer communication. Such components include computer hardware. These are the tangible physical components of the computer. For instance, a Modem is one of the hardware devices that have the ability to send signals from one computer to another over telephone signals. This comprises of the computer inputs for communication purposes. The other component is computer software. This controls the computer operations, according to the instructions of the users. The software allows computers to interact with other computers through the management of resources. Some of the utility software contains language translators for easy communication between computers. Another component is the availability of a database. This is the storage of related data in an organized manner. This enables users to retrieve information when they require, for communication purposes. Through the Database Management System (DBMS), users have the ability to create, maintain, and access a database. The other component is the availability of a network. Computers have the ability to converge telephone networks, in addition to other networks of communication that use both data and voice for ...Download file to see next pagesRead More

...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”). This allows data to be transmitted over alternate pathways in the event that some channels are congested using the segments. On reaching the destination, the data bits are then re assembled into a continuous data stream from binary bits into text or video that a human can read. The computer communicates with other computers in the...
