2. Type of computer
Digital computer Analog computer Hybrid Computer
Micro Computer
Main frame
Computer
Super Computer
Home PC
Mini Computer
3. Analog computer
Analog computer measures and answer the
questions by the method of “HOW MUCH”.
The input data is not a number infect a
physical quantity like tem, pressure, speed,
velocity.
Signals are continuous of (0 to 10 V)
Accuracy 1% Approximately
High speed
Output is continuous
Time is wasted in transmission time
5. Digital Computers
Digital computer counts and answer 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 level of (0 V or 5 V)
Accuracy unlimited
low speed sequential as well as parallel
processing
Output is continuous but obtain when
computation is completed.
6. Micro Computer
Micro computer are the smallest computer
system. There size range from calculator to
desktop size. Its CPU is microprocessor. It
also known as Grand child Computer.
Application : - personal computer, Multi user
system, offices.
7. Mini Computer
These are also small general purpose system.
They are generally more powerful and most
useful as compared to micro computer. Mini
computer are also known as mid range
computer or Child computer.
Application :- Departmental systems, Network
Servers, work group system.
9. Main Frame Computer
Mainframe computers are those computers that
offer faster processing and grater storage
area. The word “main frame” comes from the
metal frames. It is also known as Father
computer.
Application – Host computer, Central data
base server.
10. Super Computer
Super computer are those computer which are
designed for scientific job like whether
forecasting and artificial intelligence etc. They
are fastest and expensive. A super computer
contains a number of CPU which operate in
parallel to make it faster. It also known as grand
father computer.
Application – whether forecasting, weapons
research and development.
12. Hybrid Computer
The combination of features of analog and digital
computer is called hybrid computer. The main
example are central national defense and
passenger flight radar system. They are also
used to control robots.
13. Classification of Digital computer
Desktop
Workstation
Notebook
Tablet PC
Handheld computer
Smart Phone
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 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
operation. In the hybrid types of computers the
Digital counterparts convert the analog signals to
perform Robotics and Process control
20. Apart from this, computers are also categorized on the basis of physical
structures and the purpose of their use. Based on Capacity, speed and reliability
they can be divided into three categories of computers:1. The Mainframe
Computer – These are computers used by large organizations like
meteorological surveys and statistical institutes for performing bulk
mathematical computations. They are core computers which are used for
desktop functions of over one hundred people simultaneously. 2. The
Microcomputer – These are the most frequently used computers better known
by the name of “Personal computers”. This is the type of computer meant for
public use. Other than Desktop Computer the choice ranges as follows:
Personal Digital Computer Tablet PC Towers Work Stations Laptops Hand Held
Computer 3. The Mini computer – Mini computers like the mainframe computers
are used by business organization. The difference being that it can support the
simultaneous working of up to 100 users and is usually maintained in business
organizations for the maintenance of accounts and finances.
