Computer 20091205 (student preso)

  1. 1. Computer<br />
  2. 2. The history of computers starts out more than2000 years ago, at the birth of the abacus.<br />The scientists developed abacus step by step. Finally, Thomas of Colmar created the first successful mechanical calculator <br />History of Computer<br />
  3. 3. By 1822 the English mathematician Charles Babbage discovered a calculating machine, which he called the Difference Engine.<br />It could compute tables of numbers, such as logarithm tables, but it didn’t work well.<br />
  4. 4. Later on, he came up with a new idea, the Analytic Engine.<br />The two main parts of his Analytic Engine is the &quot;Store&quot; and the &quot;Mill”. In a modern computer, these are called the memory unit and the central processing unit (CPU).<br />In 1837, Charles Babbage was the first person to design a fully programmable computer.<br />
  5. 5. Scientists used Analytic Engine theory to develop more and more computer.<br />The first digital computer was the Atanasoff Berry Computer in 1937.<br />
  6. 6. The mathematician John Von Neumann invented the first Stored Program Computer.<br />In the past, computers were used for military purpose.<br />
  7. 7. Case: It has hardware inside<br />Power Supply: Full power, Normal kinds<br />Motherboard: where components reside. Such as video card, sounds card, and networking. <br />Components<br />
  8. 8. Microprocessor/CPU:This is the brain of your computer. It performs commands and instructions and controls the operation of the computer.<br />Memory - The RAM in your system is mounted on the motherboard. This is memory that must be powered on to retain its contents.<br />Motherboard<br />
  9. 9. Drive controllers - The drive controllers control the interface of your system to your hard drives. The controllers let your hard drives work by controlling their operation. On most systems, they are included on the motherboard, however you may add additional controllers for faster or other types of drives.<br />
  10. 10. Hard disk drive(s) - This is where your files are permanently stored on your computer. Also, normally, your operating system is installed here.<br />CD-ROM drive(s) - This is normally a read only drive where files are permanently stored. There are now read/write CD-ROM drives that use special software to allow users to read from and write to these drives.<br />
  11. 11. Monitor<br />Keyboard<br />Mouse<br />
  12. 12. BeOS - EPOC - IBM AIX - IBM AS400 - IBM Mainframe / OS/390 / zSeries / z/OS - Linux - Apple MacOS - Open Source - OpenVMS - Operating Systems - OS/2 - Real Time O/S - Unix - Windows 98/ME - Windows CE - Windows NT - Windows 2000 - Windows XP<br />Operating System<br />
  13. 13. 3D Graphics Modelling - AEC Design Tools - AutoCAD - Cartography - Computer Aided Design (CAD) - Computer Aided Manufacturing (CAM) - Computer Animation - Computer Graphics - Computer Imaging - Computer Simulation - Design Automation - Fractals - Geographic Information Systems (GIS) - Global Positioning Systems (GPS) - Image Processing - Mapping - MIDI - MPEG - Multimedia - Multimedia Authoring - Product Data Management (PDM) - Remote Sensing - Storyboarding - Streaming Media - Supercomputers - Virtual Reality - VRML<br />CAD, Computer Design, Graphics, Modelling and Multimedia<br />
