Learn Computer Basic @ Ease
Computer knowledge is a must to every individual, there are many school providing the computer basic knowledge to students, but learning at ease is not possible due to lack of time scheduled in the academic curriculum. In India computer literacy program has been implemented since 1996, under the supervision of NCERT. Many of the local governing body, like states government, local bodies, NGO, Central government has taken part in Computer Literacy Program. This is one of the good step that Government has taken.
NASSCOM an autonomous institution is one of the key institution to implementing the Computer Literacy Program in various part of India. NASSCOM has now focused to run IT-es (Information Technology Enabled Services ) business in rural parts of India, with the help of local entrepreneur. In India it is said that almost every fifth Indian is computer literate in one or the other ways. We all see that each and every sector is updated with computers usage. Parents need to think over and update their siblings with computer knowledge at the learning are. Computer learning is totally based on Fun and Learn concept, where awareness of computer is easily introduced to kids. Computer Learning process is non-stop process, beginners can start at any age, should start at the age of primary education.
Today lets take the first topic
What is Computer?
It is said that "Computer man-made machine, but faster than Man"
Word "computer" is derived from latin wor compute (means count or calculate), Its an electronic Device that manipulates information or "data". It has capability to store, retrieve and process data within a fraction of minute. Initially Charles Babbage is known as father of Computers. Commonly can be use to handles spreadsheets, darfting, accounting, database management. slide show, gaming. If one realize, now-a-days, Computers are used in large amount in sectors like, share trading, online booking of tickets, ATM in Banks, engineering field to design huge jobs, structure of buildings, Medical reporting. Various task are performed through computers. Computer can interpret the large amount of data in fraction of seconds.
Further Computer can be simplified this way: Basically computer is divided in two parts. Hardware and Software. Hardware is a part that has physical components such as Monitor, keyboard, mouse, printer. Software is a set of instruction or commands provided computer works according to these instruction. The basic structure of Computers can be classified as, Computer Machine is divided into five basic parts
A. Input Device
B. CPU - Central Processing Unit
a. Storage Unit - Data is Stored
b. Control Unit - Manages the information
c. ALU - Process the information
C Out Device
How does the computer works?
Initially, computer works as per information provided by the user via "Input Device" (Key Board, Mouse), the information is raw data to computers. After receiving the instruction, computer the computes and interprets the data logically and sends the result, which we can see on Monitor or screen, also print the output.
Basically, examples of Input Device are Keyboard, Mouse. CPU - Hard Disc, floppy disc, compact disc. mircoprocessor, ram access memory, read only memory and Output Device are Monitor, Printers, compact disc, floppy disc, hard disc.
Storage Device further can be classified - Primary Storage and Secondary Storage, Hard Disc, floppy disc, compact disc. mircoprocessor, ram access memory, read only memory are the parts of Storage device.
Types of Computers
Computers are classified in two types:
1. Personal Computers: Home computers are known as personal computers, small business unit, these computers are used for personal use like learning, performing day-to-day activities, internet surfing. Ideally its a single user computers. PC can be Desktop Computers or laptop/palm top computers.
2. Mainframe Computers or Super Computers: Mainframe Computers or Super Computers are used used in Space & Science technology, Big Corporate House, Search engines like google, yahoo, windows live, msn.
