Types of Computer
![Page 5: Presentation 1](https://reader033.fdocuments.in/reader033/viewer/2022052701/55d0a8e2bb61ebb9218b465c/html5/thumbnails/5.jpg)
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.

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.

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 .

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.
![Page 14: Presentation 1](https://reader033.fdocuments.in/reader033/viewer/2022052701/55d0a8e2bb61ebb9218b465c/html5/thumbnails/14.jpg)
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.

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.
![Page 18: Presentation 1](https://reader033.fdocuments.in/reader033/viewer/2022052701/55d0a8e2bb61ebb9218b465c/html5/thumbnails/18.jpg)
Difference b/w Professional & User Computer
Professional computer :-
The computer professional is the one who made the software’s applications, etc.

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.
![Page 20: Presentation 1](https://reader033.fdocuments.in/reader033/viewer/2022052701/55d0a8e2bb61ebb9218b465c/html5/thumbnails/20.jpg)
Difference b/w Computer literate & Computer
competentComputer 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.
