Definition and Meaning
Classification Of Computer Based On Size And Capacity refers to the grouping of computers according to their physical size, processing power, memory capacity, and storage capabilities.
- Size refers to the physical dimensions of a computer system.
- Capacity refers to the processing speed, memory, and data handling ability.
- Computers are commonly divided into Supercomputers, Mainframe Computers, Mini Computers, and Micro Computers.
- They can also be classified as Analog, Digital, and Hybrid Computers based on data handling.
How It Works
The working principle of computers in this classification depends on their processing power and storage capacity. Larger computers can handle more users and complex calculations compared to smaller systems.
- The computer receives input data from users or devices.
- The CPU processes the data according to instructions.
- Memory and storage capacity determine how much data can be handled.
- The processed output is delivered to users or other systems.
The difference lies in the scale. For example, a microcomputer handles single user tasks, while a supercomputer performs billions of calculations per second.
