Types Of Computers

A computer is a programmable tool. It accepts information in the form of digital data and manages it for some products on the basis of a program or a series of instructions on how the types of computers are processed.

It includes at least one processing element, usually a central processing unit (CPU) and some form of memory. The processing element performs arithmetic and logical operations and a command and control unit that can change the order of operations based on the information stored.

Types of computers:

Computers are also classified according to their physical structures and the purpose of their use. Depending on capacity, speed and reliability can be divided into four categories of computers:

Types of Computers
Types of Computers

Microcomputer: a small single-user microprocessor-based computer.

Minicomputer: a multi-user computer capable of supporting up to hundreds of users at a time.

Mainframe: a powerful multi-user computing system capable of supporting hundreds or thousands of users simultaneously.

Supercomputer: an extremely fast computer capable of executing hundreds of millions of instructions per second.


Microcomputer is an inexpensive processor with CPU as the primary business unit (CPU).Includes microprocessor, memory and input / output (I / O) functionality. Microcomputers became popular in the 70s and 80s with the advent of ever more powerful microprocessors.

A microcomputer or personal computer can be defined as a relatively inexpensive small computer designed for a single user. Companies use microcomputers for word processing, accounting, desktop publishing, and for running spreadsheets and databases administrative authority. At home, it is very popular to use virtual computer machines to play games and more recently to travel online.

Way to experiment

The term refers to a computer that stores power supplies, motherboards, and warehousing devices on top of each other in the cabinet. This is in contrast to gas regulation, where it is stored in the case of a battery. The main advantage of prototype towers is the less load space, which makes it easier to install additional hardware.

Desktop example

A computer designed to lie on a desk, usually with a monitor sitting on a computer. Computer graphics software is wide and low, but computer graphics software is narrow and long. Due to their features, computer graphics software is usually limited to three major storage devices. Graphic blocks are designed to be very small, sometimes referred to as small lines.

Fire computer

Computers are very familiar with computers. Women’s laptops weigh less than 6 pounds and are small enough to fit easily into a paper bag. Above all, the main difference between a notebook and a PC is the display screen. Laptops are using different techniques, called flat panel technology, to make light and seamless display. The quality of the notebooks makes the eyes look completely different. In terms of computing power, today’s computer systems are almost identical to PCs. They have the same CPUs, memory settings, and disk space. Computer systems have batteries that you can use without plugging them in.

Laptop computer

A small laptop small enough for you to sit on your lap. Today, laptops are more commonly known as note computers.

Subbook Computing

A laptop that is slightly lighter and smaller than a full-size laptop. Typically, subnotebook computers have a smaller keyboard and screen, but on the other hand they are the same as note computers.

Mobile computing

Laptop that is small enough to hold in your hand. Although extremely convenient to carry, notebooks have not been replaced by handheld computers due to their small keyboards and displays. The most popular handheld computers are those designed to provide PEM (information manager), such as a calendar and address book. Some manufacturers are trying to solve the little keyboard problem by replacing the keyboard with an electronic pen. However, these pen-based devices are based on handwriting recognition technologies, which are still in diapers. PDAs, pocket computers, and pocket computers are also known as laptops.


Compared to full-size computers, handheld computers are quite limited, but they are handy for specific tasks like phone books and calendars. Palm phones that use a stylus instead of a keyboard for inserts are called handheld computers or PDAs. Due to their small size, most pocket computers do not include disk drives. However, many have PCMCIA slots where you can install disk drivers, modems, memory, and other devices. PDAs, handheld computers, and pocket computers are called Palmtops.


Another type of computer is a microcomputer designed to support more than one user at a time but which can be used by one person at a time. This is a medium-sized computer between a microcomputer and a mainframe computer and includes a microprocessor, memory, input and output functions and is equipped with at least one type of data storage, usually RAM. Small computers are typically personal computers that are sold to small businesses for use in the general business and then to large businesses in a departmental business. Minicomputers are designed for control, instrumentation, human interaction and the transfer of communications that are different from calculations and record keeping. They have large storage capacity and work at high speeds. This is often used in places where multiple people have to work simultaneously, thus allowing many users to use the data simultaneously without difficulty.

Minicomputers are not only used in business organizations, but many minicomputers are also used as personal computers. It has a series of inexpensive silicon logic gates that allow utilities and kernels independent of the boot to be stored in microcomputers. These stored programs allow the minicomputer to automatically load more complex software than external storage devices without user intervention.


On the other hand, we have mainframe computers which are quite more expensive than mini-computers. In comparison, a mainframe computer works better than a mini-computer, it is capable of processing data at very high speeds, for example millions of instructions per second. Compared to ordinary PCs, mainframes usually have hundreds of thousands of times more online data storage space and can access them faster. They contain a large number of self-care functions, including integrated security features and high data management capability. Due to the mainframe’s ability to handle high-level data transactions, they are used by larger companies in almost all sectors such as banks, government agencies, and organizations that need to store large volumes of complex and important data at a high-security level, which means this is the safest compared to other types of computers.
