Historical Evaluation of Computer
➢ What is a computer? Why it is also known as a data processor?
A device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information is known to be a computer.
A computer is an electronic device which manipulates or transforms data. It accepts data, stores data, process data according to a set of instructions, and also retrieve the data when required. Hence it is known as a data processor.
➢ What is data processing? Differentiate between data and information. Which is more useful to the people and why?
A series of operations on data by a computer in order to retrieve or transform or classify information is called data processing.
| DATA | Information |
|1. Data is the piece of value that we can consider as single entity. |1. Information maybe considered as a data that has been organized and |
| |that are processed. |
|2. Data does not increase. |2. Information increases understanding. |
|3. Data can not be directly used for taking intelligent decision. |3. Information helps to take intelligent decisions. |
|4. Data is not collection of information. |4. Information is an organized collection of data. |
|5. Data comprises information. |5. Information does not comprise data. |
Between data and information, information is more useful to the people. As we know data is the raw material of a computer. On the other hand we can say data is un-organized or unprocessed information.
