SS1 DATA PROCESSING NOTE SECOND TERM (FIRST TOPIC)
Computer classification according to purpose can be classified into two different types, namely:
- General Purpose Computers.
- Special Purpose Computers.
General Purpose Computer.
These computer systems are specially designed and developed to work with standard functions and applications of computers.
These computers are mutitasking computers, very fast computers with enough memory to save data and information.
These computers are inexpensive compared with special-purpose computers.
A computer that performs everyday tasks and operations given to it falls in the category of general-purpose computers.
Examples of general-purpose computers are Personal computers such as notebooks, tablets, laptops desktop, smartphone, etc.
Special Purpose Computer.
These computer systems are designed and developed to perform particular tasks and operations and derive necessary results with great speed, accuracy, and consistency.
These computers have more processing power, storage capacity, and speed than general-purpose computers.
These computer systems allow additional devices and components to connect for better performance and enhanced functionality.
These systems can have multiple CPUs [Central Processing Unit] for more speed and handling power.
They are widely used in the following areas:
- Scientific Research.
- Military.
- Weather forecasting and Predicting Earthquakes.
- Cryptocurrency Mining.
- Space Science.
Examples of special-purpose computers are:
- Super Computers.
- Workstations.
- Servers
- Automated Teller Machine.
- Point of Sale.
- Ultrasound machine
- ECG machine

Classification of Computer According to Size
Computer classification according to size can be categorized into four different types mentioned below:
- Micro Computer.
- Mini Computer.
- Mainframe Computer.
- Super Computer.
Super Computer.
Supercomputers, with excellent storage capacity, are considered the fastest computer in data processing and handling.
They are big and have multiple CPUs [Central Processing Units] for faster data and information access and processing.
The supercomputer also uses parallel processing for better functionality, performance, and processing.
A speed is measured or counted in “FLOPS” (Floating Point Operation per Second). It can perform a speed of over 1 billion per second.
The supercomputer is designed and developed for special purposes like:
- Scientific Research.
- Weather Research
- Weather Forecasting
- Military and Defense
- Genetic Engineering
- Nuclear Engineering
- Solving complex numerical problems
- Animated Graphics
- Quantum
Examples of Super Computer..
- IBM Seirra
- Sunway Taihu Light
- Frontera Dell C640 Dell EMC
- Trinity Cray XC40
- Super MUC-NG
- Lassen IBM Power System
Supercomputers are faster machines and emit lots of heat and energy; therefore, it is mandatory to use an air conditioner to keep the devices and components of the computer cool and avoid physical damages like burning and overheating.
The supercomputer work and manages applications with tremendous speed. The supercomputer is a million times faster than mini, mainframe, and microcomputers.
The supercomputer’s speed is because of thousands of processors installed on them that make them extraordinary.
Mainframe Computer
These computers are small in size compared to a supercomputer. Mainframes are fast and can store a massive amount of data and information.
They have extremely impressive data processing and handling abilities, and hence the number of users can connect to them quickly for better data sharing and functionality.
They support tens of thousands of remote computers and can work as a “Host Computer”; they are pretty good when considering working with different operating systems.
They can store data and deliver millions of instructions and guidelines per second.
Uses of Mainframe computers
- Banking.
- Government Databases.
- Airline and Railway Reservation.
- Population Database.
Some Examples of Main Frame Computer are as follows:
- IBM Z890.
- Hitachi’s Z800.
- CDC Cyber Series.
- IBM 4381.
- ICL39 Series.
Mini Computer
Minicomputers are considerably smaller in size compared to supercomputers and mainframe computers.
Minicomputer consists of more than 1 CPU [Central Processing Unit], making them faster than microcomputers and costlier than microcomputers.
Mini computers work slower than mainframe computers. Minicomputers are called “Workstation” or “Midrange Computers”.
Mini computers are extensively used in small businesses and medium-sized companies.
Examples of Minicomputers.
- Micro VAX
- IBM AS/400
- VAX
- Texas Instrument TI-990
Micro Computers.
Microcomputers are compact in shape and size and use a microprocessor, processor, or CPU for processing and calculations.
They are comparatively relatively smaller than other computers.
The microprocessor is cheaper than the technology used by [Mini, Mainframe, and Super].
This computer can be accommodated inside a briefcase and placed on a desk. Therefore this tiny computers are called “Microcomputers”.
CLICK TO WATCH THE CLASSIFICATION OF COMPUTER ACCORDING TO TYPE
The primary function of the microprocessor is to perform arithmetic and logical operations at high speed with great accuracy.
Microcomputers can perform trillions of operations per second. The speed of the microprocessor can range from megahertz to gigahertz.
There are different types of microprocessors, they are:
- Single core processor
- Dual Core Processor.
- Quad Core Processor.
- Hexa Core Processor
- Octa Core Processor
- Deca Core Processor
Microcomputers are also called “Personal Computers” [PC]. This is because they can only be used by a person at a time.
They are extensively used and utilized in small businesses for file handling, word processing, and spreadsheets, and they are also called general-purpose computers.
Examples of Microcomputers include
Laptops, desktops, smartphones, embedded systems, PDAs, Palmtop etc.
