3. Analog Computer
Analog Computer
Analog computer measures and answers the questions by
the method of “HOW MUCH”. The input data is not a
number; it is a physical quantity, such as temperature,
pressure, speed, or velocity.
Signals are continuous (0 to 10 V)
Accuracy 1% Approximately
High speed
Output is continuous
Time is wasted in transmission time

5. Digital Computers
Digital Computers
Digital computer counts and answers the questions by the
method of “HOW Many”. The input data is represented
by a number. These are used for the logical and
arithmetic operations.
 Signals are two levels of (0 V or 5 V)
 Accuracy unlimited
 low-speed sequential as well as parallel processing
 Output is continuous but obtained when computation is
completed.

6. Micro Computer
Micro Computer
Microcomputers are the smallest computer
systems. Their size ranges from a calculator
to a desktop. Its CPU is a microprocessor. It
is also known as the Grandchild Computer.
• Application: - personal computer, multi-user
system, offices.

7. Mini Computer
Mini Computer
These are also small, general-purpose systems.
They are generally more powerful and more
useful than compared to microcomputer. Mini
computers are also known as mid-range
computers or Child computers.
• Application:- Departmental systems, Network
Servers, work group systems.

9. Mainframe Computer
Mainframe Computer
Mainframe computers are those computers
that offer faster processing and greater
storage capacity. The word “mainframe”
comes from the metal frames. It is also
known as Father Computer.
• Application – Host computer, Central
database server.

10. Super Computer
Super Computer
 Supercomputers are those computers that are
designed for scientific jobs like weather forecasting
and artificial intelligence etc. They are the fastest
and expensive. A supercomputer contains a number
of CPUs that operate in parallel to make it faster. It
is also known as grand grand-grandfather computer.
Application – whether forecasting, weapons
research, or development.

Hybrid Computer
The combination of features of analog
and digital computers is called a hybrid
computer. The main examples are the
central national defense and the
passenger flight radar system. They are
also used to control robots.

18. Types of Computers :
Types of Computers Analog Computers: The
analog computer is almost an extinct type of
computer these days. It is different from a
digital computer in respect that it can
perform numerous mathematical operations
simultaneously. It is also unique in terms of
operation as it utilizes continuous variables
for the purpose of mathematical
computation. It utilizes mechanical,
hydraulic, or electrical energy or operation

19. Hybrid computers:
Hybrid computers: These types of computers are,
as the name suggests, a combination of both
Analog and Digital computers. The Digital
computers, which work on the principle of the
binary digit system of “0” and “1”, can give very
precise results. But the problem is that they are too
slow and incapable of large-scale mathematical
operations. In the hybrid types of computers, the
Digital counterparts convert the analog signals to
perform Robotics and Process control
