A computer is an electronic device that can perform operations according to a set of instructions called a program. There are several types of computers: digital computers operate on discrete data using binary digits and include microcomputers, minicomputers, mainframe computers, and supercomputers; analog computers use continuously variable physical quantities; and hybrid computers exhibit features of both analog and digital computers. A microcomputer is a small computer with a microprocessor as its central processing unit that became popular in the 1970s-80s; they are used in homes for education and medical applications like storing records.

2. A Computer is an
electronic device that
can perform a variety
of operations in
accordance with a set of instruction
called program.

3. Types of Computer:-
 DIGITAL
• Micro computer
• Minicomputer
•Mainframe computer
• Super computer
 ANALOG
 HYBRID

4. Digital computer, any of a class of devices
capable of solving problems by processing
information in discrete form. It operates on
data, including magnitudes, letters, and
symbols, that are expressed in binary form—
i.e., using only the two digits 0 and 1.

5. Micro Computer
A microcomputer is a small, computer with a microprocessor
as its central processing unit (CPU).Microcomputers became
popular in the 1970s and 80s with the advent of increasingly
powerful microprocessors.
Application
Home:- Families use microcomputers for education; software
can hold thousands of book volumes worth of information.
Medical uses:- The first microcomputer (dubbed the "Sac State
8008") was built specifically for storing medical records.

6. Mini Computers
A minicomputer, or colloquially mini, is a class of smaller
computers that evolved in the mid-1960s.
They use of transistors and core memory
technologies, minimal instructions sets and less
expensive peripherals such as the ubiquitous
Teletype Model 33 ASR.

7. Mainframe computer
The term referred to the large cabinets that housed the central
processing unit and main memory of early computers.
Modern mainframes can run
multiple different instances
of operating systems at the
same time.

8. Super computer
The fastest type of computer. Supercomputers are very
expensive and are employed for specialized applications that
require immense amounts of mathematical calculations. For
example, weather forecasting requires a supercomputer.
Application
1. Weather forecasting, aerodynamic research,
2. 3D nuclear test simulations,
3. Radiation shielding modeling,
4. Molecular Dynamics Simulation,etc.

9. An analog computer is a form of
computer that uses the continuously
changeable aspects of physical
phenomena such as electrical,
mechanical, or hydraulic quantities to
Model the problem being solved.
Application:-
1. Measuring temperature, pressure, speed,
Velocity,etc.
2. Communication,etc.

10. Polish Analog computer

11. Hybrid computers are computers that exhibit
features of analog computers and digital
computers.
Application:-
1. A petrol pump contains a processor that converts fuel
flow measurements into quantity and price values.
2. In hospital Intensive Care Unit (ICU), an analog device
is used which measures patient's blood pressure and
temperature etc, which are then converted and
displayed in the form of digits.

12. Example of Hybrid computer

13. A Personal computer is a desktop computer in a
form intended for regular use at a single
location, as opposed to a mobile laptop or
portable computer.
