  4. 4. 5-1 Electronic Data Processing<br />There are different types of data processing system and each performs one or more required operations on data by means of various devices.<br />Automatic Data Processing (ADP) – when the machine performs most of the required operations.<br />Electronic Data Processing (EDP) - when the machine is an electronic digital computer or simply as a computer system<br />
  5. 5. Types of Data Processing System<br />Automatic Data Processing<br />Electronic Data Processing<br />Hardware<br />Software<br />Peopleware<br />
  6. 6. 5-2 Hardware<br />It refers to the physical equipment or components of an electronic data processing<br />
  7. 7. 5-3 Software<br />Software commonly includes such programs as well as any operating aids that extend the capabilities of the computer.<br />Stored programs tell the computer what steps to take , what data to work on and what to do with the results.<br />
  8. 8. 5-4 Peopleware<br />It represents the personnel involved in system analysis, programming, computer operations, system maintenance, and the like.<br />Systems analysis and design are the jobs of the systems analyst.<br />Program development is the specialty of the programmer.<br />System development is carried out by computer operators , input data preparation staff and output preparation clerks.<br />
  9. 9. Advantages of Electronic Data Processing<br />Speed <br /><ul><li>Computers operate on data at such phenomenal speeds that they can produce results which would simply not feasible otherwise.</li></ul>2. Accuracy<br /><ul><li>The electronic circuitry of computers is such that, when the machines are programmed correctly and when incoming data is error free , the accuracy of the output is relatively assured.
  10. 10. Computers are considered 100% accurate.</li></li></ul><li>Advantages of Electronic Data Processing<br />3. Automatic Operation<br /><ul><li>An electronic computer can carry out sequence of many data processing operations without human intervention</li></ul>4. Decision Making Capability<br /><ul><li>A computer can perform certain decision instructions automatically.
  11. 11. Determine whether a certain statement is true or false.
  12. 12. Based on the result, choosing one or the other course of action out of alternatives included in the computer program.</li></li></ul><li>Advantages of Electronic Data Processing<br />5. Compact Storage<br /> Electronic data processing systems have the ability to store large amounts of data in a compact and easily retrievable form<br />6. Discipline it imposes<br /> To solve a problem with a computer you must first understand the problem and second , program the computer to give you the right answer.<br />
  13. 13. 5-6 The Stored-Program Concept<br />Before a computer can actually read data , process it and produce information , it must read set of instructions called program which actually indicates what processing is required .<br />Programs, like data, are stored in the computer<br />
