Classified of Computers based on Configuration🖥💻 :

Based on performance, size,cost and capacity, the digital computers are classified into four different types:
🔅Super computers
🔅Mainframe computers
🔅Mini computers
🔅Macro computers

Super Computers:

🌟The mightiest computers but at the same time, the most expensive ones are known as Super computers.
🌟Super computers process billions of instructions per second.
🌟In other words, Super computers are the computers normally used to solve intensive numerical computers.
🌟Examples of such applications are stock analysis, special effects for movies, weather forecasting and even sophisticated artworks.

Mainframe Computers:

🌟Mainframe computers are capable of processing data at very high speeds- hundreds of million instructions per second.
🌟They are large in size.
🌟These systems are also expensive.
🌟They are used to process large amount of data quickly.
🌟Some of the obvious customers are banks, airlines and railway reservation system, aerospace companies doing complex aircraft design, etc.

Mini Computers:

🌟The Mini computers were developed with objective of bringing out low cost computers.
🌟Ther are lower to Mainframe computers, in term of speed and storage capacity.
🌟Some of the hardware available in Mainframe were not included in the Mini computer handled by hardware in Mainframe computers were done by software in Mini computers.


🌟Hence the performance of Mini computers is less than that of the Mainframe.
🌟However, the Mini computer market has diminished somewhat as buyers have moved towards less expensive but increasingly powerful personal computers.

Micro computers:

🌟The invention of microprocessor (single chip CPU)gave birth to the micro computers.
🌟They are several times cheaper than mini computers.
🌟The micro computers are further classified into,
🔅workstation
🔅personal computers
🔅 laptop computers
🔅smaller computers

🌟Although the equipment may vary from the simplest computer to the most powerful, the major functional units of the computer system remain tha same :
🔅input
🔅processing
🔅storage
🔅output

Workstations:

🌟Workstations are also desktop machines mainly used for intensive graphical applications.
🌟They have more processor speed than that of personal computers.
🌟Workstations use sophisticated display screens featuring high – resolution colour graphics.
🌟Workstations are used for executing numeric and graphic intensive applications such as Computer Aided Design (CAD), simulation of complex systems and visualizing the results of simulation.

Personal Computers:

🌟Today the personal computers are the most popular computers systems simply called PCs.
🌟These desktop computers are also known as home computers.
🌟They are usually easier to use an more affordable than Workstations.
🌟They are self-contained desktop computers intended for an individual user.
🌟Most often used for word processing and small database applications.

Laptop Computers:

🌟Laptop computers are portable compilation fit in a briefcase.
🌟Laptop computers, also called notebook computers, are wonderfully portable and functional, and popular with travelers who need a computer that can go with them.

Getting Smaller Still:

🌟Pen-based computers use a pen like stylus and accept handwritten input directly on a screen.
🌟Pen-based computer are also called Personal Digital Assistant (PDA).
🌟Special engineering and hardware design techniques are adopted to mske the portable smaller and light weight computers.
