At the present time, with the advancement of technology, the types of computers and the most prominent information about them have become a matter of concern to many of those interested in technological development. Computers are one of the most important and indispensable devices, as they are used daily for many tasks, and through the website Moments News The most important types of computers will be presented, divided according to their size, use, and operating principle.

Types of computers according to size

Computers vary in the size over which they have been developed over the years. To become smaller and lighter and to suit the nature of users' work, computers are divided according to their size into the following:

Supercomputer: It is the largest type of computer in terms of size and the highest in price. The supercomputer consists of one device or several devices that work together. This type is characterized by high specifications and the willingness to perform a very large and enormous number of calculations at one time, and it is used in huge scientific experiments. Such as space tracking, nuclear testing, weather forecasting, and the National Oceanic and Atmospheric Administration.

A large mainframe computer is a device that supports a number of users at the same time. It is characterized by its large size and high-quality specifications. It is also very expensive. Large companies and institutions use it to set transaction rules, applications, and large commercial databases. This requires a high degree of security compared to small computers.

Small computer: Small computers include all the features of a large computer, but they are smaller and lighter, ranging from 12 inches to less than 7 inches. They are multi-use and have high processing power, but they are not greater than the processing power found in supercomputers and mainframes. Microcomputers exist in several forms, including mobile phones, small desktop computers, and MP3 players.

Types of computers according to use

There are many types of computers, and each type has its own characteristics. With specifications In particular, the following are the types of computers divided according to use:

Desktop computer: This is a type of computer that is used in offices. It is very similar to a personal computer, but with higher specifications and capabilities. It is characterized by a large storage capacity and has multiple uses, but in recent years, its use has decreased. Smartphones and computers have become more widely used and dominant due to their availability at affordable prices for most consumers.

Personal computer: It is the computer of only one individual and is not used by anyone else. Its specifications are somewhat low, and it exists in different forms. Some of them have all types of connections that include Wi-Fi and Bluetooth, and some of them contain working screens. Touch method, and personal computers operate on the Windows operating system.

Tablet computer: This type is a touch screen with all the computer components inside it, and its specifications are specific. Its price is fairly cheap, and it is cheaper than a laptop computer, and it works very similar to smart phones, through which games, pictures, and drawings can be downloaded. On the screen using a special stylus that comes with it, and its storage capacity is small compared to other types of computers.

Laptop computer: This type is characterized by its small size and light weight compared to other types, which allows it to be carried anywhere and is similar in shape to a book. It combines all its components—the screen, the keyboard, the memory processor, the trackball, and the hard disk—in a special battery-powered package. It is characterized by the fact that it works for a limited period of time without the need to connect it to the electrical current, as it is equipped with a rechargeable battery.

Personal Data Assistant Computer: It is a small computer, light in weight, usually does not contain keyboards, and relies only on touch-screen technology, mainly to enter information and take notes. This type operates with a battery that lasts for several hours and is then recharged.

Workstation computer: It is a computer with very high specifications because it contains central processing units and hard drives distinguished by their large capacity. For this reason, it is used in fields that require processing large amounts of data, high performance, and showing results. This type is also used. In 3D graphics, game development, and video game play, workstation computers are available at a high price.

Server computer: It is the main device used in large companies and institutions, medical, security, educational, and factories. The specifications of the main server in it come with high precision. It also contains powerful processors, large-capacity memory, and large hard drives, and its price is somewhat expensive. Compared to other types, this type is indispensable in companies with a large number of employees and administrators.

There are many types of computers, each type of them is characterized by special specifications, and the following are the types of computers divided according to the use:

Types of computers according to the principles of operation

Computers differ in terms of their operating principles into two types: Computers Digital and analog computers, and the following is the definition of each of them:

Analog computers: They are among the oldest computers that were developed over the years. This type stores continuous data, such as temperature, speed, pressure, and weight, and performs calculations using measurements because it does not need to convert the data into symbols and numbers.

This type of computer is the most complex and uses the flow of electricity and mechanical movement. Analog computers were used until digital computers appeared.

Digital computers: They are computers that help process information accurately in a few seconds by using the binary number system 0 and 1, where information written in English is converted into that binary language, which creates a language of communication between humans and computers.

The digital computer consists of three parts: the input, which is the data that the user enters; the processing of the input using a specific intrusion; and the output, which is displayed after the processing is complete.

Hybrid computers: They are computers that combine an analog computer and a digital computer, as they are designed in a way that makes their components fast and accurate through the use of powerful analog units in calculations. It also features digital memory and efficient processing speed. Hybrid computers are used in industries and companies. The big one.

By reaching the end of the article, it will have been realized that computers are among the most important and indispensable devices, as they are an integral part of daily life, by mentioning the multiple types and uses of computers.
