Digital, analog, and hybrid computers are the three main types. Digital computers operate using binary digits while analog computers represent continuous values. Hybrid computers have qualities of both. The document also distinguishes between computer professionals and users, as well as literacy and competency. Professionals have advanced degrees and create software, while users operate existing programs. Literacy means basic understanding and tasks, while competency performs simple operations without full understanding.

2. TOPIC:-
1. Types of Computer.
2. Difference b/w computer
professional & computer user .
(or)
Difference b/w computer Literate
& computer competent .

3. Types of Computer
There are divided in to following three types of
computer .
 Analog computer
 Digital computer
 Hybrid computer

4. Types of Computer

5. Analog Computer
 The computer which
provide us information
in continuous form are
called analog
computer.
 Analog computer
represent physical
quantities such as
voltage pressure
speed temperature
 Its output is usually
displayed on a
graphs.

6. Characteristics of the Analog
Computer
There are following characteristics of analog
computer.
 Speed.
 No state (1) & (0).
 easy to develop & small memory.
 Calculate analog quantities.
 Result not reliable.
 Give output in the form of graphs.

7. Characteristics of the Analog
Computer
 Continuity in working
 Fewer function.

8. Analog Computer
Uses:-
 Used in engineering & Science,
 Used to calculate analog quantities.
Example:-
Thermometer, Speedo meter,
Sphygmomanometer etc,

9. Digital Computer
 A digital computer work
with digits.
 Everything is described
in two states i.e. either
on or off .
 The number 1
represents on & 0
represents the off
states.
 Given output in digital
format.

10. Characteristics of The Digital
Computer
These characteristics are following below
 Speed.
 Big memory.
 Reliable result.
 Calculate mathematical.
 Given output in digital format.
 Difficult to develop.
 Less electric power.

11. Digital Computer
These computer are
further divided into
difference types such
as,
 General Purpose:-
e.g. of
digital watch ,digital
cameras , PCs .
 Specific Purpose:-
e.g. use in
restaurants
,automobiles etc .

12. Digital Computer
Uses:-
 Used in all filed of life.
 Used in all calculation of mathematically
Example:-
Score Bore , apple Macintosh, Digital
petrol pump etc.

13. Hybrid Computer
 The computer
which have qualities
of both digital &
analog computers are
called hybrid
computer.
 Hybrid computer has
the speed of analog &
the accuracy of digital
computer.

14. Characteristics of Hybrid
Computer
There are the following characteristics of hybrid
computers.
 Reliable & Provide accurate result.
 Work fast & Speedy.
 Helpful in hospitals.
 Given output in both graphic & numeric
form.
 Both qualities in these computers.

15. Hybrid Computer
Uses:-
 Used in hospital (ICU) .
 Scientific laboratories .
 Used in petrol pumps .
 Used in industrial unit.
Example :-
ICU hospital computer .

16. Difference b/w Digital & analog
Computer
Analog Computer :-
 Slow Speed.
 Low memory.
 No State.
 Difficult to use.
 Less reliable.
 Use in Engineering &
Science.
 e.g. Analog Clock ,&
thermometer etc .
Digital Computer :-
 Fast speed.
 Big memory.
 Two State.
 Easy to use.
 More reliable.
 Use in all field of life.
 e.g. Digital Laptop &
Digital Camera etc .

17. Difference b/w Professional &
User Computer
Professional Computer :
 Someone who is an
expert in the field of
computer science.
 A person with an
advanced degree in
computer science &
computer engineering
User computer :-
 A person who uses
computers for work or
entertainment or
communication or
business.
 Computer user dose
not advanced degree
in computer science
& computer
engineering.

18. Difference b/w Professional &
User Computer
Professional
computer :-
 The computer
professional is the
one who made the
software’s
applications, etc.
 Some examples: A
software engineer
working in Microsoft is
a computer
professional.
User Computer :-
 The computer user is
the one who uses the
things produced by
the computer
professional.
 Some example: A
computer user using
the applications like
MS office; computer
games etc.

19. Difference b/w Professional &
User Computer
Example:-
Those
types of person who
dealing with computer
at least 2 or 3 years
or they have a
degree. Degree is a
most important part
for a computer
professional.
Example :-
Those
types of person who
dealing with computer
since 10 years but on
one program they are
the computer user.
Like WORD, POWER
POINT etc.

20. Difference b/w Computer literate
& Computer competent
Computer literate :-
 Computer literacy means
the knowledge of
computing ideas and
terms and the ability to
perform basic tasks using
the computer .
 The computer
literate understand
the basics of
computer operations:
Computer Competent :-
 Computer competent
perform simple tasks with a
computer. Email, research,
interaction with others via
the internet.
 It requires some definite
level of expertise on one or
more aspect of computer &
dose not understand
computer operations.

21. Difference b/w Computer literate
& Computer competent
For Example: -
Turn on
power; use a
keyboard; run
an application; send
an email, surf the
web, etc.
For Example: -
. Email,
research, interaction
with others via the
internet. Creating and
editing documents,
spreadsheets and
maybe a slide
show (PowerPoint).
