Computers have ingrained themselves into our daily lives due to the fast advancement of technology. However, have you ever questioned how a computer operates? What procedure is taking place there?
Like every other machine, a computer has a fundamental architecture. It consists of several components. These components handle the input and generate the intended outcome. Let’s look at the Block Diagram of Computer. You’ll then comprehend how each component contributes to the whole operation.
Input

The input unit receives all data sent to the computer. The input unit consists of many gadgets. Similar to a keyboard, mouse, scanner, etc. To put it another way, each of these gadgets serves as a liaison between users and computers.
The data to be processed is fed into the input unit. The computer accepts binary-formatted raw data. Following the data’s processing, the intended output is generated.
In the Block Diagram of Computer following are the input unit’s primary purposes:
- Consider the user-processable data.
- Create a machine-readable format for the data provided.
- After that, send the transformed data to the computer’s main memory. Connecting the user and the computer is the only goal. Additionally, this makes communication between them simple.
Central Processing Unit

The Central Processing Unit, or CPU, is frequently referred to as the “Brain” or “Heart” of the computer. A Central processing unit is a physical, electronic device that can conduct various activities such as arithmetic and logical computations. It can carry out all calculations, comparisons, and procedures inside the CPU.
- CPU operations
- Bring up every instruction from memory.
- Take care of the order of each instruction
- To establish communication between all external devices
- Manage the transfer of all information and commands from one component to another.
- Conduct the calculations required by the software application.
- The Central Processing Unit is divided into the arithmetic logic and control units.
Arithmetic logic unit (ALU)
All arithmetic and logical operations are carried out by the Arithmetic logic unit (ALU), which analyzes information through input devices and stores it in the central memory storage unit.
An arithmetic unit can handle the simple operations of addition, subtraction, division, and multiplication. A logical unit can control the AND, OR, EQUAL, GREATER THAN, LESS THAN, and other logical operations.
The Logical Unit can also carry out other tasks like choosing, matching, comparing, and combining data. Logical Units can also conduct bit-shifting operations, such as left shift represented by the operator and right shift represented by the >> operator.

Control Unit (CU)
As its name suggests, the control unit is responsible for managing all tasks, operations, and activities. The computer performs all of this.
- The memory unit transmits a series of instructions to the control unit.
- The control unit transforms those instructions after that.
- These instructions are then transformed into control signals.
These control signals aid in the prioritizing and planning of tasks. As a result, the control unit in the Block Diagram of Computer system coordinates the work inside the computer in tandem with the input and output units.
Memory Unit
The memory unit houses all the data that has been processed or needs to be processed. All of the data is concentrated in the memory unit. When necessary, it communicates it to the relevant area of the computer.
The CPU and memory module operate simultaneously. It facilitates quicker data access and processing.
Hence expediting and simplifying procedures.
There are two kinds of computer memory:
- Primary memory
- Secondary memory
1. Primary Memory
This kind of memory is unable to hold large amounts of information. It is thus only employed to hold current data. It just stores transitory data. When the power is turned off, it might delete it; consequently, it is sometimes referred to as primary or transitory memory.
RAM is an illustration of first-hand recollection. The CPU may directly access this memory. It is employed for both reading and writing. Data must be transmitted to the RAM and then to the CPU to be processed.
2. Secondary Memory
Temporary data is kept in the main memory, as previously mentioned. As a result, future access is impossible. Secondary memory is employed for long-term storing needs. It is also known as supplementary memory or persistent memory. A hard disc is an example of secondary memory. Even during a power outage, data is not simply deleted.
Output
What the output block in the Block Diagram of Computer is used for should come as no surprise. The user then receives any data given to the computer for processing via an output device. The output block is followed by devices like projectors, printers, and monitors.
The output block displays data as digital or printed copies. Printer for copying paper. Only displays are made on the monitor. The output block accepts binary-formatted data from the computer. It then changes it to a format that is readable by others.
