Forms of computer system

What created by computer ?
To create a full-fledged computer, with two main parts are needed. That's are-

(1) The hardware

(2) Software.

1. Hardware: Computer hard goods that can be used to create all of the hardware. For example - monitor, CPU, keyboard, mouse, etc..

Mother board

The computer hardware can be divided into four parts.That's are -

(a) Input Unit  

(b) Central Processing Unite

(c) Memory Unit

(d) Output Unit.

(A) Input Unit : The part of the computer and the data are entered in the input Unite. Based on this information, the computer can perform all the work. Computer data is entered through a different medium that key-board, mouse, scanner, joystick, microphone etc..

(B) Central Processing Unite: All the information that the monitoring, analysis, and are processed by the Central Processing Unite. This part of the heart of the computer. Inside the gray matter of the brain, such as all kinds of functions, it is processed by the computer to control all the activities. Then sends it to the output of useful lessons.

(C) Memory Unit: That entered the computer can store all the information in the memory unit. See the results of his work on the computer, insert data is not the end, Storing it becomes necessary. These can be divided into two main computer memory. Such as -

(1) The Internal memory: The memory of the computer equipment in the container bearers to the memory of the memories inside. It's just the type two, for example -

 (a) Read Only Memory (ROM): That can be Read Only Memory between the information can not be changed, but this kind of memory is read only memory. The memory of the computer it is running. Generally, the manufacturer of the computer, the memory of some of the commands are permanent.

(b) Random Access Memory (RAM): The memory can be seen, read, and can be changed, Its called Random Access Memory, or RAM. This memory is temporary memory. Because it can be changed arbitrarily and can be removed.

(2) External Memory: Any information that is stored in the computer via the external memory. This memory computer memory to store all the data. Any help will be required memory for storing data. Such as hard disk, floppy disk, etc. The container market has some new and useful external memory. The CD, DVD, MO disk, Zip disk, super disks, etc. However, all of these different kinds of external memory drive is required if you want to use the container.

(D) Output Unit: The results are displayed in all the parts of the computer - this port of the Output Unit.  This is a very important part of your computer. In this section, the results are displayed on the computer all the work. The results show that the device of monitor the primary and significant. Monitor is the visual display unit.  Print the results to a paper in word, its need to the Printer. Listen to the result in sound its need to the Speaker.

2. Software : Dynamism of the computer software. The energy required to run the software in the computer.
Such as the hands, feet, ears, head, etc have not ‍all, its are complete run with the dynamism. Just like it do not have the hardware in the computer, it would run the software.
We have seen in hardware, but can not seen software. All the software used on the computer that they can be divided into three .

(I) system software: the computer to start as early as the type of software used in the system software. Generally, it has been called DOS, or disk operating system.

(B) Application Software: computer after the initial writing, drawing, listening to music, or any of the software used for the design, Its called of the application software. There are many types of computer software to be used. In Microsoft Word, MS Excel, Adobe Photoshop, Quarks Express, Quarrel Draw, Adobe page maker and application software are in use. Application software is very broad horizon. There's no end. Their work for the benefit of big companies withdrew their software., We play video games is also a software application.

(C) Utility Software: computer running when the user is facing some problems sometimes. To solve this problem are some useful software. The name of the software is utility software. Take away from the computer for viruses, such as: anti-virus.

There is also a kind of software that computer users are not comfortable at all. The name of this software is virus software.
