Computers
  • Computers are in widespread use today
  • Business
  • Education
  • Home
  • Computers used for many things
  • Office work
  • Science and Research
  • Games and Entertainment
  • Multimedia production
  • Data storage
  • and loads more...

Computer System
  • Computer System consists of two main areas of
    functionality
  • Hardware
  • Physical components to a computer system
  • Stuff you can touch and hold
  • Wires, transistors, keyboard, printer etc.
  • Software
  • Instructions given to the hardware
  • Programs or applications to run on the hardware
  • Sets of instructions
  • The stuff you can do useful things with
  • E.g.- Windows, Dreamweaver, MS Office, etc.

10
The Computer
  • The computer is a machine
  • TOM (Totally Obedient Moron)
  • Carries out instructions
  • Consists of electronic components
  • Performs three main tasks
  • Accepts INPUT
  • Performs a PROCESS on the input
  • Produces OUTPUT from the process

11
Hardware
  • Essential Hardware Components
  • Input
  • Keyboard, mouse
  • Processing
  • Central Processing Unit (CPU)
  • E.g.- Intel Pentium n, AMDAthlon
  • Output
  • Monitor, printer
  • Memory
  • Temporary data storage, with fast retrieval
  • E.g.- RAM (Random Access memory)
  • Permanent storage
  • A form of media to store data for a long term
  • E.g.- Hard disk drive
  • E.g.- ROM (Read Only Memory)

12
Input Process Output
  • Input
  • Telling the computer what to do
  • User Make me a cup of coffee!
  • e.g.- Mouse or keyboard
  • Process
  • Computer carries out a task in response to
    instructions
  • Computer Mixes water and coffee granules. Pour
    into cup.
  • e.g.- Processor
  • Output
  • Computer displays the results of task
  • Computer Hands user coffee cup
  • e.g.- Monitor
