Classification of Computer System:: The Computer is an electronic device that can store a gigantic amount of data and information.
They are capable of performing numerous calculations and various tasks and jobs given to them instantly with rapid speed and incredible accuracy.
There are special computers for specific tasks and operations for example for space investigation, exploration, nuclear science, and genetic engineering special types of computers are designed and developed.
For Example : Supercomputer
Supercomputers are used and utilized for performing special, specific tasks and operations that require amazing processing power and data storage capacity.
Personal Computers or Desktop Computers are moreover used for entertainment, watching movies, playing songs, online games, graphics, and some applications software that are used in day-to-day life.
For administrators, executives, representatives, and businessman laptop use is common and is utilized broadly and widely because of its mobility and portability.
Laptops are used with the assistance of a battery available inside every laptop and it can also perform each and every task like a Desktop or Home PC (Personal Computer).
Therefore different classifications of computers can be done with the help of some features that are size, functionality, capabilities, and speed.

Three Types of Computer
The Computer are classified into three main types
- Analog Computers
- Digital Computers
- Hybrid Computers (Analog + Digital)
1. Analog Computers.
Analog computers measure “Physical Quantities” for example Temperature, Voltage, Pressure, and Electric Current.
These are the quantities that are continuously varied and persistently change from one measurement to another, just like the temperature of a human being or individual.
They process the given data or instruction or information into analog data or simple data.
They are equipped for measuring instead of counting or checking.
They are also specifically designed for measuring and can perform arithmetical calculations upon numbers where numbers are indicated by physical quantities or physical amounts.
The Analog computer is used in scientific and industrial ventures, where they have to screen temperature, voltages, and electric currents.
Examples of Analog Computer
- Speedometer
- Thermometer
2. Digital Computers.
The “Digital Computers” can complete or perform Arithmetic and logical operation when given to them in a type of binary number system.
These types of computers are not for measuring physical quantities such as temperature, electric current, and voltages.

They are high-speed programmable machines or computers which can play out numerous mathematical calculations and can store data or information.
When any instruction or direction was given to them they convert that instruction or data or information into a machine-readable form that is 0s or 1s which is called a “Binary Number System”.
Examples
- Desktop Computer OR Personal Computer (PC).
- Laptop.
3. Hybrid Computers (Analog + Digital)
They possess both the qualities and features of Analog and Digital computers.
They can measure or gauge physical quantities as well as count or check and are generally used for scientific and medical use.
Just, for example, there are some machines that can calculate the heartbeats and temperature of the human body and convert or change them into numbers.

The computer is an advanced electronic device or tool that can perform numerical tasks and jobs at incredible speed and accuracy.
Various computer systems are designed and developed to complete special tasks and operations.
The computer system is categorized and distinguished based on its size, processing powers, applications, and other features and characteristics.
Compact-size computers are used as personal computers like desktop computers, tablets, smartphones, and laptops.
The computers are also categorized and classified according to their use and purpose.
Classifications of Computers With Examples
The computer system is considered one of the most important inventions ever.
The modern computer system is a crucial part of our lives, and it is almost impossible to imagine our lives without its use and utilization.
The computer system with an internet connection has made our lives more comfortable and peaceful. The task and daily work can be done with just a few clicks.
Computer systems are more versatile and reliable compared to other devices. Depending on your needs and preferences, they can be used as personal computers, laptops, or tablets.
Various computer systems are available in the market, some of which are mentioned below.
- Desktop Computer.
- Laptops.
- Palmtop.
- Tablets.
- Mobile Phones.
What are the Different Classifications of Computer Architecture
Depending on configurations, preferences, and specifications, various computers are available in the market.
Before buying any computer or laptop, you must check the configuration your computer manufacturer provides.
It would help to consider some of the features your computer or laptop should possess. They are mentioned below.
- The CPU is considered the Brain of the Computer. Therefore, it is highly recommended to choose an advanced processor before buying, as the speed of the computer system entirely depends upon how powerful your processor is.
- Secondly, RAM [Random Access Memory] is also a key component or device that plays an important role in computer speed. It is commonly said that the more RAM, the speedier your computer will work. The latest applications like spreadsheets, word processors, and games need more memory to function properly. RAM also enhances the overall performance of the computer system.
- The latest computer motherboard is also key to computer speed and performance. The motherboard is a device that enables all the other components, like CPU, RAM, Hard Disk, etc., to attach itself, helping them to receive power from SMPS [Switching Mode Power Supply]. Before buying, you need to check the compatibility issues that commonly arise when buying a motherboard.
- Hard disk drives permanently store huge amounts of data and information. Insufficient hard disk space results in inconvenience while working on the computer. The latest software needs huge space for installation as its size is enormous compared to the previous software.
