A computer is one of the most clever inventions of mankind. Thanks to the computer technology, i was able to achieve a competent storage and processing of data; we could rest our brains by employing computer memory capacities for storage from the information. Because of computers, we’ve been able accelerate daily work, carry out critical transactions and achieve accuracy and precision in work output. The computers of the earlier years were of the size of a sizable room and were required to consume huge amounts of electric power. However, using the advancing technology, information technology has shrunk towards the size of a small watch. Depending on the processing powers and sizes of computers, they have been classified under various types. Let’s explore the classification of computers.

Different types of Computers

Based on the operational principle of computers, they’re categorized as analog computers and hybrid computers.

Analog Computers: They are almost extinct today. These are different from an electronic computer because an analog computer is capable of doing several mathematical operations simultaneously. It uses continuous variables for mathematical operations and utilizes mechanical or electrical energy.

Hybrid Computers: These computers are a mixture of both digital and analog computers. In this type of computers, the digital segments perform process control by conversion of analog signals to digital ones.

Following are some of the other important types of computers.

Mainframe Computers: Large organizations use mainframes for highly critical applications for example bulk data processing and ERP. The majority of the mainframe information technology has the capacities to host multiple operating systems and operate like a quantity of virtual machines and can thus substitute for several small servers.

Microcomputers: Some type of computer having a microprocessor and its central processing unit is actually a microcomputer. They don’t occupy space around mainframes. When supplemented with a keyboard and a mouse, microcomputers could be called as pcs. A monitor, a keyboard and other similar input output devices, computer memory as RAM and a power supply unit come packaged inside a microcomputer. These computers can fit on desks or tables and serve as the very best selections for single-user tasks.

Personal computers are available in a variety of forms for example desktops, laptops and personal digital assistants. Let us look at all these kinds of computers.

Desktops: A desktop will probably be utilized on a single location. The spares of a desktop computer can easily be bought at relative lower costs. Power consumption is not as critical as that in laptops. Desktops are widely popular for daily use in workplaces and households.

Laptops: Similar in operation to desktops, laptop computers are miniaturized and optimized for mobile use. Laptops run on a single battery or another adapter that charges the computer batteries. They’re enabled by having an inbuilt keyboard, touch pad acting as a mouse and a liquid crystal display. Its portability and capacity to work on electric batteries have served as a boon for mobile users.

Personal Digital Assistants (PDAs): It is a handheld computer and popularly known as a palmtop. It has a touchscreen and a memory card for storage of data. PDAs may also be effectively used as portable audio players, browsers and smartphones. Most of them can access the web by way of Bluetooth or Wi-Fi communication.

Minicomputers: When it comes to size and processing capacity, minicomputers lie in between mainframes and microcomputers. Minicomputers will also be called mid-range systems or workstations. The word started to be popularly used in the 1960s to refer to relatively smaller third generation computers. They took up the area that might be needed for a refrigerator or two and used transistor and core memory technologies. The 12-bit PDP-8 minicomputer from the Digital Equipment Corporation was the very first successful minicomputer.

Supercomputers: The highly calculation-intensive tasks can be effectively performed by means of supercomputers. Quantum physics, mechanics, weather forecasting, molecular theory would be best studied by means of supercomputers. Remarkable ability of parallel processing and their well-designed memory hierarchy give the supercomputers, large transaction processing powers.
Wearable Computers: A record-setting part of the evolution of computers was the advance of wearable computers. These computers can be worn on the body and therefore are often used in the study of behavior modeling and human health. Military and health care professionals have incorporated wearable computers into their daily routine, as a part of such studies. Once the users’ hands and sensory organs are engaged in alternative activities, wearable computers are a big help in tracking human actions. Wearable computers are consistently functioning they do not have to be turned on and off and therefore are constantly interacting with the user.

They were a few of the various kinds of computers available today. Exploring the rate of the advancement in technology, we can definitely look forward to many more kinds of computers soon.
