2 Ka answer
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit. It includes a microprocessor, memory and minimal input/output circuitry mounted on a single printed circuit board
2 type of micro computer
There are 7 types of microcomputers given in the following :
Desktop computer. The desktop computer belongs to the category of the microcomputer. ...
Laptop. A laptop, laptop computer, or notebook computer is a small, portable personal computer (PC) with a screen and alphanumeric keyboard. ... Laptops are folded shut for transportation, and thus are suitable for mobile use. Its name comes from lap, as it was deemed practical to be placed on a person's lap when being used.

1. Micro Computer
The personal computers, laptops, tablets, and mobile phones that we use in our daily life fall under the category of microcomputers. These type of computers consist of microprocessor and various input/output devices embedded on a printed circuit board. They are less complex and comparatively inexpensive. Microcomputers are advantageous because they are flexible, portable, and loaded with features.
2. Mini Computer
Minicomputers are most popular for their quality of multiprocessing. It means that mini computers can use multiple processors connected to a common memory and the same peripheral devices to perform different tasks simultaneously. Minicomputers have greater complexity than microcomputers. These are also known as mid-range computers and are generally used for applications like engineering computations, data handling, etc.
3. Mainframe Computer
Mainframe computers were first introduced during the early 1930s and were properly functional in the year 1943. They are known for their exceptional data handling capacity and reliability. This quality is used in applications where bulk data handling and security are of main concern. For example, in banks, during the census, etc. Harvard Mark 1 was the first mainframe computer.
4. Super Computer
A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

1. Micro Computer :
Micro Computer, as name suggests, is a personal computer that is specially designed for personal use and generally consists of single chip that is CPU, data memory, I/O buses, etc. It can be used by one person at a time. Its type includes tablet and smartphone microcomputers, desktop micro computers, workstation and server microcomputers, etc.
Example : Laptop, desktop, IBM-PC, etc.
2. Mini Computer :
Mini Computer, as name suggests, is a type of computer that offers most features and capabilities that large computer generally offers. It generally supports multiple users at a time so one can say that it is a multiprocessing system. It is a smaller computer designed for business applications and services, and also can do time-sharing, batch processing, online processing, etc.
Example : AS/400 computers, Motorola 68040, MV 1500etc.
