  1. Computer Hardware Objective 2.01: Classify computer components

  2. Essential Question: • What are the parts and features of a computer?

  3. What is a computer? • An electronic device that receives data, processes data, stores data, and produces a result (output)

  4. Types of Personal Computers • Desktop computer: designed to be used on a desktop • Laptop computer: portable computer designed to be small enough and light enough to be used on your lap • Tablet computer: portable computer primarily operated by touching the screen rather than using a physical keyboard

  5. Computer Components: Hardware Hardware – the physical equipment of the computer system that you can see and touch

  6. Monitor Computer Case (Processor inside) Floppy Disk Drive Keyboard Speakers CD ROM Drive Mouse USB Drive

  7. Input Devices • Used to put information into the computer • Allow you to communicate with your computer Webcam Mouse Keyboard Microphone Joystick Scanner

  8. Output Devices Speakers • Send information out of the computer • Allow the computer to communicate with the user Monitor – produces soft copy output Projector Printer – produces hard copy output Headphones

  9. Processing Device Central Processing Unit (CPU) – known as the heart or “BRAIN” of the computer, responsible for processing the information that has been entered into the computer

  10. Internal Storage- Allows you to store information inside of the computer Hard drive: Allows the fastest access to information RAM (Random Access Memory) – temporary storage ROM (Read Only Memory) – long-term storage External Storage- Allows you to use devices to store information outside of the computer Floppy disks CD-ROMs (Compact Disc ReadOnly Memory) CD-RW (Compact Disc ReadandWrite) DVDs (Digital Video Disc) USB/Flash drives Storage Devices

  11. The Information Processing Cycle

  12. What Does IPOS Stand For? • Input • Processing • Output • Storage

  13. What Happens During The IPOS Cycle? • Input when information is entered into the computer; the computer receives information • Processing when the computer processes the information that has been entered • Output when information leaves the computer • Storage when information is stored to be used later

  14. How the IPOS Cycle Works: Input Storage Processing Storage Output
