. What are the different types of digital computers? Explain each type?
Answers
Answer:
Different types of Digital Computer
Digital computers are a device that needs to be programmed in order to receive the desired output.
It uses electronic technology to generate, store and process different types of data.
Based on the size and type of the device, these digital computers are classified into four categories.
Microcomputer
Minicomputer
Mainframe computer
Supercomputer
Microcomputer
A Microcomputer is not really expensive and it comes with a microprocessor as its Central processing unit and input/output devices.
These computers are generally called personal computers and few of the examples are IBM pc, Apple, Dell.
Minicomputers
Minicomputers are known as mid-range computers that contain one or more processors.
They support multiprocessing which means these multiple processors share the same computer memory and other required peripheral devices to perform the given task.
Minicomputers are generally used for processing transactions, file handling, managing database.
Mainframe computers
Mainframe computers are generally large size computers mainly used for storing large amounts of data and processing. It is known for a high level of reliability.
These machines are used by an organization which requires crucial application such as census, customer statistics for large calculation which requires a high volume of data processing.
Super Computers
Supercomputers are very expensive and the world’s fastest computers available.
These computers have thousands of processors that perform trillions of calculations per second and hence the fastest known ever.
Supercomputers are used extensively in enterprises and organizations that require massive calculations.
Digital Computer Micro computer Supercomputer Mainframes Minicomputer4. A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and input/output devices.
