What is the background processing?
Background processing can be best defined by its action. Simply performs tasks in the background of the computer while the user of the computer performs actions in the foreground of the computer. For example, when processing a background, a computer user can actively manipulate one application using a computer and screen screen, while separate operations are performed simultaneously and in the background. In many cases, the background processes work completely autonomously and the user does not even realize that the processes are carried out.
Data processing in the background of any computer is an integral part of the computer. The background can be compared to the application that the user works with the screen, high priority, priority of the same level or low level. As long as the background processing is achieved within an acceptable time frame and does not interfere with the user's activities or the overall function of the computer, it can be considered as a successenful.
one popularAn example of the background processing includes a common printer. When a computer user works on a text processor to enter a document, saves it and orders the computer to print it, the command is transferred to the printer via the background processes of the computer. This activity takes place independent of what is happening on the computer screen. In fact, a computer user can continue to make a document adjustment, open and enter a new document, or work in a brand new application while the computer deals with the background processing.
Lack of interaction between computer user and background processes should not be misunderstood that processes are not important. There are certain background processes that are as important as those applications that interact with in the forefront. Some computer to prefer tasks and regulate how much energy is devoted to everyone. In general, however, the background process is a relatively low priority and has a minimum output.
background processes can usually be categorized jako either a demon or a computing task. The average computer user will be more familiar with DAEMONS work because it helps to take care of common features such as E -mail transmission, web page serving and time synchronization. Their interactions are not with users, but with programs or other computers in the network. They use very small memory and do not store great emphasis in using CPUs, so computer users can work on the machine for years without realizing that these processes exist and actually take place while focusing on the task of the computer.
