Syeda Mustajab Zahra

TOPIC:-1. Types of Computer.

2. Difference b/w computer professional & computer user .

(or) Difference b/w computer Literate

& computer competent .

Types of Computer

There are divided in to following three types of computer .

Analog computer Digital computer Hybrid computer

Types of Computer

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.

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.

Characteristics of the Analog Computer

Continuity in working Fewer function.

Analog Computer Uses:-

Used in engineering & Science, Used to calculate analog quantities.

Example:-Thermometer, Speedo meter,

Sphygmomanometer etc,

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.

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.

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 .

Digital Computer

Uses:- Used in all filed of life. Used in all calculation of mathematically

Example:-

Score Bore , apple Macintosh, Digital petrol pump 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.

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.

Hybrid Computer

Uses:- Used in hospital (ICU) . Scientific laboratories . Used in petrol pumps . Used in industrial unit.

Example :-

ICU hospital computer .

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 .

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.

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.

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.

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.

Difference b/w Computer literate & Computer

competentFor 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).
