Recognize the Structure of a Computer System and its Explanation [LENGKAP]

In this article I will explain the structure of a computer system and its explanation. As it is known that based on its function the components in a computer are divided into 3, namely input components process components and output components. The three components work together to produce an environment called a computer system.

The word system comes from the Latin "systema" which is a unit consisting of several components or elements that are interrelated with one another in achieving certain goals. 19659002] The main purpose of a computer system is to process data with support from hardware, software and users to produce information.

Computer System Structure  Computer system structure and explanation

The computer system itself has structures that are defined as the methods used so that each component in a computer is interrelated and works together in carrying out its functions properly. There are no specific provisions about how to structure a system in a computer.

In general, there are structures in a computer divided into 5 main parts, input devices, output devices, I / O Ports CPU and Memory. For more details, see the description of each of the following components.

1. Input Device  Computer System Structure - input device

Input devices are included in the computer hardware that handles the activity of receiving input from outside the system. The function of this input device is to enter data or commands given by the user into the system. Examples of devices that are part of the input device are keyboard, mouse, joystick, scanner, touchpad and many more.

2. Output Device  output device

Output device is hardware that handles output activities. The function of the output device is to display the results of data processing, either in the form of soft copy hard copy or sound. Examples of computer hardware included in the output device are monitors printers, speakers, projectors, etc.

3. I / O Ports  input-output port

I / O Ports are said to be connectors under the control of the processor to handle input and output activities. Or in other words, this port is used to connect every device that comes from outside the computer, such as a printer, scanner, mouse or USB.

Usually, this port is located on the back of the CPU on the computer and inside the motherboard, while on a laptop The ports are on the right and left.

4. CPU (Central Processing Unit)

 Computer System Structure - CPU

CPU (Central Processing Unit) is a computer hardware called the brain of a computer system. Because, sooner or later the performance of a computer is determined by the technology and quality of the CPU used.

There are 3 types of components in the CPU, namely the control unit, register and ALU ( Aritmathic Logic Unit ). The control unit is a part that functions to regulate the course of the program, the register functions as a temporary storage place for the data being processed to proceed to the next processing. While the ALU has the task of carrying out arithmetic and logic operations based on the instructions given.

5. Memory  memory

Memory refers to devices that function as storage media in a computer system. There are two types of memory properties used, volatile is temporary storage where data will be lost when the computer is turned off, and non-volatile is permanent storage which will store data even if the computer is not turned on. [19659002] Based on its location, memory is divided into two parts, namely internal and external memory. This internal memory is said to be the main memory in a computer system, such as RAM ( Random Access Memory ) and ROM ( Read Only Memory ).

6. Control Bus

As the name suggests, contorl bus is part of a computer system that functions to control the use of access to data bus and bus address. In principle, data channels and address channels are used simultaneously by all components, so that a control bus is needed to control their use. This control bus is equipped with command signals specifying the operations to be formed.

7. Bus Address (Channel Address)

The bus address is related to the source or destination address on the data bus. In addition, this address bus is used to select a memory location or port to carry out write and read operations. In order for all devices to be connected to a computer system must have an address to be accessed. For example, the CPU will read a word from memory, then the CPU will put the data address on the address channel.

8. Data Bus (Data Channels)

Data bus is part of a computer system that becomes a path of transfer between data contained in a computer system module. The data will be moved from input devices to CPU, CPU to memory, or from memory to output devices. Bus width determines the amount of data that can be transferred once in a while. Typically, the data bus consists of 8, 16, 32, 64 or more parallel lines.

Thus information about the structure of a computer system and its explanation. Hopefully the above explanation is easy to understand and useful for you. Thank you for your visit.
