1. Mjpru bareilly Department of B.Ed./M.Ed . Paper 17 (B) – computer education Assignment topic – classification of computers Assignment A ssignment Submitted to submitted by Dr. Pratibha sagar name - Ranjana Ma’m class- B.Ed. 2 year roll no. 237139040015

2. Classification of computers On the basis of size . On the basis of functionality On the basis of data handling .

3. On the basis of size. Micro computer Mini computer Mainframe computer Super computer

4. Micro computer  personal computer or  microcomputer , is a general-purpose computer for personal use. This type of computer comprises a CPU, memory, an input unit, and an output unit. This type of computer is appropriate for personal tasks such as watching a movie, completing an assignment, etc.

5. Mini computer   Minicomputers are smaller, less expensive, and less powerful than mainframes or supercomputers but more pricey and powerful than personal computers. These computers are multi-user systems with more than one user working simultaneously. These computers are primarily used for engineering and scientific computations, file management, business transaction processing, and other similar tasks.

6. Mainframe computer Mainframe computers have a large amount of memory and  processors  and can perform billions of transactions and simple calculations in real time. This type of computer is primarily used for transaction servers, commercial databases, and applications that require high  reliability ,  security , and  speed . These are the computers to have when ‘0’ downtime is acceptable.

7. Super computer Let's explain the type of computer known as a supercomputer and its significance in modern computing. Supercomputers are the  largest and fastest computers , capable of processing trillions of functions in seconds. These computers are primarily used for data-intensive and computation-intensive scientific tasks such as password encryption and decryption, weather forecasting, exploring the solar system, molecular modeling, etc .

8. On the basis of functionality. Servers Workstation Information appliances Embedded computers.

9. Servers Servers are nothing but dedicated computers which are set-up to offer some services to the clients. They are named depending on the type of service they offered. Eg: security server, database server. 

10. Workstation Those are the computers designed to primarily to be used by single user at a time. They run multi-user operating systems. They are the ones which we use for our day to day personal / commercial work.

11. Information appliances They are the portable devices which are designed to perform a limited set of tasks like basic calculations, playing multimedia, browsing internet etc. They are generally referred as the mobile devices. They have very limited memory and flexibility and generally run on “as-is” basis.

12. Embedded computers They are the computing devices which are used in other machines to serve limited set of requirements. They follow instructions from the non-volatile memory and they are not required to execute reboot or reset. The processing units used in such device work to those basic requirements only and are different from the ones that are used in personal computers- better known as workstations.  

13. On the basis of data handling Analog computer Digital computer Hybrid computer

14. Analog computer These types of computers process analog data. (Analog data is constantly changing data that cannot have discrete values.) These computers read the continuous change in input, process it, and then output it.  Analog computers can be classified into four types: slide rules, differential analyzers, castle clocks, and electronic analog computers. These computers also monitor real-world conditions such as temperature, wind, sound, and movement.

15. Digital computer These types of computers stores data in a numerical format (0 and 1) and performs operations on that data using mathematical manipulation. Any input given in any language is first converted into binary language, and then the computer processes the information.

16. Hybrid computer Now let's explain the type of computer known as a hybrid computer and its significance in modern computing. A hybrid computer is made after combining analog and digital computers. As a result, these computers are fast like analog computers and have memory and accuracy like digital computers.  These computers are commonly used in specialized applications requiring analog and digital data processing. A hybrid computer, for example, is used in hospitals to monitor patients’ heartbeats.
