Three components form the basic computer structure and function. These three components are input devices, the control processing unit (CPU), and output devices. The central processing unit (CPU) can also be divided into two parts that form the basic structure of computers. These two parts are the arithmetic logic unit (ALU) and the control unit (CU). The control unit is responsible for controlling CPU operations. The arithmetic logic unit is responsible for processing data functions.
Structure of computer
All computer types have the same basic computer structure and function. They all follow basic operations. These operations are responsible for converting raw input data into some information that is useful for the users of computers. This basic structure includes an input unit, CPU (central processing unit), and output unit.
Input unit
Input units are the components or devices of the computer by which we can enter any data into the computer. Input devices are responsible for translating all the information that we add to the computer into a form only understood by the computer. All computer types have an input unit.
The central processing unit (CPU)
The central processing unit or CPU is known as the computer’s brain. The CPU plays an important role in forming the basic structure of computers. CPU. It does all the data operations. The CPU is responsible for storing data, intermediating results, and instructions of programs. The central processing unit controls the operations of every part of the computer.
A CPU has three components. These three components are
Control unit
The memory unit
ALU or arithmetic logic unit
Output unit
The device that helps us get all the required information from the computer is known as the output unit. The output unit acts as a linkage between users as well as computers. Output devices are responsible for translating the computer’s output into a form that is understandable by the users.
Serial number | Operations | Description of operations |
Take input operation | This is the process in which users enter data as well as instructions into the system of computers. | |
Processing data operation | This is the process in which operations like logical operations as well as arithmetic operations are performed. They convert all the required data into useful information. | |
Store data operation | In this process, data and instructions are stored so that they are available or present during processing if required. | |
Control the workflow operation | Control of the workflow means the direction of the manner as well as the sequence in which all the operations are performed and used. | |
Output information operation | This is the process in which all the useful information is produced. All this information or results are produced in such a way that they are in the form of a visual display or a printed report. |
Memory unit
Another important component of all computer types is the memory unit. A memory unit is a place where all the data, such as programs as well as files, are stored. It becomes easy as well as quick for a CPU to access all the information through the memory unit.
Two types of memory units are main. These two types are RAM or random access memory and ROM or read-only memory.
RAM is responsible for storing data when used, whereas ROM is responsible for retaining data when power is not provided. The type of memory and the size of memory determines the performance of the system of computers. They also form the basic structure of computers. How quickly a program can be loaded is also based on the memory unit. It is important to have enough RAM because of all the projects and changes made on them.
Control unit
Everybody knows of the central processing unit (CPU), but there is one more component that affects the processing of data. This unit is known as the control unit. The control unit does not receive any form of input from users; rather, it is responsible for sending commands to other computer components, for example, the instruction decoder and register. The computer’s control unit highly affects everything that happens inside the computer.
It handles everything from the execution of instructions to the running of programs. The control unit does not have any physical form, but still, it forms the basic structure of a computer.
Conclusion
The basic structure of computers is the components that are basic to the performance and functioning of the computer. It is a simple concept that describes how any data is entered into the central processing unit with the help of input devices, such as a mouse, scanner, keyboard, joystick, and others, and printed on the screen by the output unit. There are three components of the basic structure of a computer. These components are the control processing unit (CPU), an input unit, and an output unit. The memory units and a control unit also form the basic structure of a computer. The memory unit stores the data, and the control unit sends the commands. To get any task done on the computer, it is necessary to enter the data or instructions into the computer first. Computer function defines how a computer system works and acts based on the basic structure in a practical environment.
