Before computers there were not telephone answering machines‚ handheld calculators‚ fax machines‚ personal computers. People did what they had to do without these things. People wrote letter by hand or with a typewriter‚ they also kept track of data and numbers in ledgers. They were not texting each other‚ there was either in person or over the phone. . Computers are integral to our daily lives and there are millions used daily. Computers are used at home‚ work‚ and school. They are also embedded

PROCESSING OF DATA INTRODUCTION Data processing is an intermediary stage of work between data collection and data analysis. The completed instruments of data collection‚ viz.‚ interview schedules/ questionnaires/ data sheets/field notes contain. a vast mass of data. They cannot straightaway provide answers to research questions. They‚ like raw materials‚ need processing. Data processing involves classification and summarisal1on of data in order to make them amenable to analysis Processing of data requires

UNIT-I INTRODUCTION INTRODUCTION TO COMPUTER The term “Computer” is derived from the Latin word “Computare” which means “to compute” or “to calculate”‚ so it is considered to be calculating device. In fact‚ the main objective of inventing the computer was to create a fast calculating machine. But now-a-days more than 75% of non-mathematical or non-numerical work is carried out by the computers. Today‚ computer technology has spread to every sphere of existence of modern man‚ from railway

Data Input and Output Essay The methods of input of data may vary consistently. For instance‚ for printed questionnaires‚ the traditional method of input implies the use of computers’ keyboard by means of which the information that is supposed to be printed in a questionnaire is input. The same method may be used for long documents‚ though this may imply the use of different software applications. For instance‚ for printed questionnaires the simplest word processors may be used‚ while long documents

Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according
