  2. DISCOVERING COMPUTER Tuesday, September 9, 2014

  3. DATA • Data is the collection of Facts & Figures. • or • Collection of Information is called Data. INFORMATION • Information is the Required Result after Processing of Data. Tuesday, September 9, 2014

  4. TYPES OF DATA • Alphabetic or string (A-Z) and symbols like +, - \ @ # $ % / etc. • Numeric (0-9), • Alphanumeric (PIII, CG125) • Date or time (MM-DD-YY) • Graphics, pictures, images, video files, sound files etc. Tuesday, September 9, 2014

  5. DATA PROCESSING CYCLE In Collection Out Verification Calculating Processing Tuesday, September 9, 2014

  6. COMPUTER Computer is an Electronic Device, which Receive Data, Process It and Give Us Our Required Result. Tuesday, September 9, 2014

  7. Advantages of Computer • Accurate In Processing. • Very high processing speed. • Space saving. • Time saving due to high speed . • Transportation of data through CD or floppy disks or hard disk. Tuesday, September 9, 2014

  27. CPU (Central Processing Unit) A main part of the Computer where every process accomplish that we perform. It is also called brain of Computer. Tuesday, September 9, 2014

  28. CPU (Central Processing Unit) It is divided into three main parts • ALU • CU • Computer Bus Tuesday, September 9, 2014

  29. ALU (Arithmetic & Logic Unit) • All arithmetic and logical operations are performed by the ALU under the supervision of control unit • CU (Control Unit) • Control Unit controls the overall working of a computer and also co-ordinates between the different devices attached with the computer. • Computer Bus • Bus’s Are Electric Signals. Tuesday, September 9, 2014

  30. Types of Buses Data Bus It is used to transfer data from one device to another. AddressBus The address bus (sometimes called the memory bus) transports memory addresses which the processor wants to access . Tuesday, September 9, 2014
