Types of computers based on different characteristics

Everyone utilizes computers daily, whether for work or personal reasons. However, we are unaware that we utilize different types of computers for different purposes. For example, a mainframe computer will be used by a doctor at the hospital, while a graphic artist will use a workstation computer at their office. Our usage varies depending on the type of machine.

The most basic classification of computer types is based on their intended use. General and special purpose computers are the two categories of computers.

  • General-purpose computers:

    Basic input/output functions such as arithmetic, smaller-scale data storage, and extremely basic activities are performed by general-purpose computers. Laptops, calculators. Desktop computers and mobile phones are examples of general-purpose devices.

  • Special-purpose computers:

    These systems, on the other hand, are designed to accomplish a certain task. Engineering computers for IT organizations, multimedia systems, and personal digital assistants (PDAs) the best examples.

The computers can be further differentiated based on their size and data handling capabilities beyond this basic segmentation. Let us try and understand them:

Computer classification based on data handling capabilities:

Analog computers:

These computers operate continuously, regardless of the input fluctuations such as instability in current, temperature or electric, and mechanical parts. Oscilloscopes, thermostats, and thermometers are the best examples of analog computers.

These computers can accept data directly from the devices without having to convert it to a numerical value. They continuously monitor physical amount changes and display the results on a dial or scale. Examples of this type include a speedometer and a mercury thermometer. Analog computers are divided into four categories:

  • Slide rules:

    This is the most basic analog computer, designed to solve basic arithmetic problems. It is made up of two rods, the first of which includes marks that move into place to line up with the second rod.
  • Differential analyzers:

    This is a particular device that uses a wheel and disc mechanism to perform differential calculations.
  • Castle clock:

    They could incorporate the display of time, zodiac, and solar and lunar orbits if it has the ability to save programming instructions.
  • Electronic analog computers:

    In these systems, the electrical signals travel between capacitors and resistors without any mechanical engagement.

Key features:

  • It is a real-time operating system that continually represents data at the same moment within a specific range.
  • Calculates without the need for third-party software to convert input/output to electronic form and vice versa.
