Draw a block diagram of a computer system with control and data signals. Explain the three parts of a computer systems
Answers
Answer:
Mainly computer system consists of three parts, that are central processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). The CPU is like the heart/brain of the computer. ...
Answer:
Three parts of a computer system are :
- Input:
This is the process of entering data and programs into the computer system. You should know that computer is an electronic machine like any other machine that takes raw data as input and performs some processing that results in processed data. Therefore, the input device brings data from us to the computer for processing in an organized manner.
- Storage:
The permanent storage of data and instructions is called storage.The data must be entered into the system before the actual processing begins. Because the processing speed of the Central Processing Unit (CPU) is so fast, the data must be provided to the CPU at the same speed. Therefore, the data is first stored on the storage drive for faster access and processing. This memory unit or main memory of the computer system is designed to perform the above functionality.
- Processing:
The task of performing operations such as arithmetic and logical operations is called processing. The Central Processing Unit (CPU) takes data and instructions from the storage unit and performs all kinds of calculations based on the instructions given and the type of data provided.It is then sent back to the storage unit.
- Output:
This is the process of generating results from the data to obtain useful information. Likewise, the output produced by the computer after processing must be stored somewhere on the computer before it is delivered to you in human-readable form. Again, the output is stored on the computer for further processing.
