What is computer?
Computer is an electronic that helps us to store and process our data and instruction at high speed and accuracy . It can receive the information perform basic operator like calculation & comparison and produce results according to the given instruction.
Know about the computer.
Computer is derived from the Latin language is “computare” which means to sum up, to count and calculate. The invention of computer who is the global scientist which named is “Charles Babbage”
, he is known as the father of computer and the mother of computer is “Lady Ada Augusta Love Lace”. The full name of computer is “Common Operating Machine purposely used to Technical and Educational Research”. It is easily to calculate sum, subtract, divide and multiply in BODMAS rule in mathematically also to manage our data with logical unit . It easily to transfer information and data from one device to another device.
Characteristics of computer.
- Speed – Computer works at very high speed. It can execute millions of instruction per second. It speed measure in “Hertz” Hz, KHz, MHz, GHz. ( 1 nano second = 10–9 second )
- Accuracy – Computer is an accurate machine, it doesn’t mistake by any chance ( except the system problem). It perform calculation without making any error and produce information in accordance to the data enter ( Gigo-Garbage In and Garbage out). That is if we input wrong information the computer will produce wrong result.
- Reliability – Computer is a reliable device. It doesn’t fail to produce result . It calculate exactly as per the given instruction work at place where human beings cannot.
- Versatility – Computer is a versatile in nature for example – it can work various kind of input and can reduce multiple kind of output like sound, graphics, text and animation etc. it is a single machine performing hundred types of tasks.
- Storage Capacity – A computer has very large memory store ( bit or giop). It can store large volume of data in small place which can be retrieved as and when required.
