Main Functions of Computer

The word ‘Computer” is abstracted from the word “Compute” which, means calculate. But if we restrict computer definition that computer is a device, which, helps us in solving our mathematical problems, it would be injustice with the computer. Though, there is no doubt that computer helps us to solve our mathematical problems but to solving and helping in our mathematical problems is just one of the works, performed by computer. So, we can say that computer is device, which can help us in:
Programming, Processing and storing the data we can develop programs according to our requirements and needs. We can process our data on computer to make it information and computer stores data, which is also very important role. All these functions of computer are very important and play very vital role to create “Global Village”. It takes the data for processing then process it, stores it and shows/provides information. These mentioned tasks of computer are called “Input”, when we enter some data in computer it called “Input” after inputting the data, next step is process (we can store the unprocessed data too) then it process the data. It called “Processing” and next it gives results after processing, which called “Output”. And finally, computer stores the data for future use.
There are two major parts of computer.
1) Hardware
2) Software

So, we can say that computer is the combination of hardware and software and it takes inputs give results after processing and stores data for future use
