Computers differ based on their data processing abilities. They are classified according to:
- Purpose
- Data handling
- Functionality
These are designed to perform a range of tasks. They have the ability to store numerous programs but lack speed and efficiency
General-purpose computers
These are designed to handle a specific problem or perform a specific task. A set of instructions is built into the machine
Specific-purpose computers
Employ electrical parameters, such as voltages, resistances, or currents, to represent the quantities being manipulated. They measure continuous physical magnitudes and do not deal directly with numbers.
Analog Computers
Operate with information, numerical or otherwise, represented in a digital form. They process data into a digital value (in 0s and 1s) and provide results with greater accuracy and speed.
Digital Computers
incorporate the measuring feature of an analog computer and the counting feature of a digital computer. For computational purposes, they use analog components, while for storage, they use digital memories.
Hybrid Computers
These use continuous physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.
Analog Computers
Perform calculations and logical operations using quantities represented as digits, usually in the binary number system.
Digital Computers
Capable of inputting and outputting both digital and analog signals, offers a cost-effective method for performing complex simulations.
Hybrid Computers
The most expensive of all computers. These are large, general-purpose computers capable of executing more than 10,000 million instructions per second and have storage capacities of millions of bits per chip. They are used to solve complex multivariate mathematical problems, such as atomic nuclear and plasma physics, seismology, aerodynamics, etc.
Supercomputer
Very large in size and offer maximum computing power. A large number of peripherals can be attached to them, are generally used in large networks of computers with the mainframe being the central point of the network. They use satellites for networking.
Mainframe Computer
Smaller versions of mainframes. They offer the same computing power as their bigger counterparts but are cheaper in cost, smaller in size, and more reliable. They do not require air conditioning and can be operated at room temperature.
Mini Computer
A computer whose CPU is a microprocessor, where all components are on a single integrated circuit chip.
Microcomputer
Designed for individual use, whether for personal use, small business automation, or professional work, versatile and can be used for a variety of applications, including computer literacy, fun and games, business applications, programming, etc.
Personal Computer (PC)
