5 Computer Types
  • Supercomputers
  • Priced from 1 million to 350 million
  • High-capacity machines with thousands of
    processors
  • Multi-user systems
  • Mainframe Computers
  • Workstations
  • Microcomputers
  • Microcontrollers

25
5 Computer Types
  • Supercomputers
  • Mainframe Computers
  • Until late 1960s, the only computer available
  • Cost 5,000 - 5 million
  • Multi-user systems accessed using a terminal
  • Terminals only have a keyboard and monitor cant
    be used alone
  • Workstations
  • Microcomputers
  • Microcontrollers

26
5 Computer Types
  • Supercomputers
  • Mainframe Computers
  • Workstations
  • Introduced in early 1980s
  • Expensive, powerful personal computers
  • Used for scientific, mathematical, engineering,
    computer-aided design (CAD), computer-aided
    manufacturing (CAM)
  • A less-expensive alternative to mainframes
  • Microcomputers
  • Microcontrollers

27
5 Computer Types
  • Supercomputers
  • Mainframe Computers
  • Workstations
  • Microcomputers
  • Personal computers that cost 500 to 5000
  • Used either stand-alone or in a network
  • Types include desktop, tower, notebooks, or
    Personal Digital Assistants (PDAs)
  • Microcontrollers

28
5 Computer Types
  • Supercomputers
  • Mainframe Computers
  • Workstations
  • Microcomputers
  • Microcontrollers
  • Also called embedded computers
  • Tiny, specialized microprocessors inside
    appliances and automobiles
  • They are in microwaves, programmable ovens,
    blood-pressure monitors, air bag sensors,
    vibration sensors, MP3 players, digital cameras,
    e-pliances, keyboards, car engine controllers,
    etc.

Discussion Question Now, how many of you would
say you have NOT used a computer today?
29
Why become computer savvy?
  • Know what computers can do for you
  • Know the limitations of computers
  • Know how computers can harm you
  • Know how to solve computer problems
  • Know when how to get help

30
Common Computer Uses...
  • Supermarket Checkout
  • Automobiles
  • CD Player
  • Microwave Ovens
  • Video Games
  • Home Computers
  • Check Processing
  • And Many More...

31
Importance of Computers
  • Speed
  • Accuracy
  • Consistency
  • Reliability
  • Storage Capacity

32
Computers help to
  • Make us more productive
  • Make better decisions
  • Reduce costs

33
The Revolution
  • Stone Age
  • Bronze Age
  • Industrial Revolution
  • Information Age
  • Information Society

34
The Information Age
  • Information
  • Has value
  • Is bought and sold

35
Computers and Information
  • Computers make
  • Data collection easier
  • Production of information easier, faster, better
  • Information available in more useable forms
  • Help us be more effective

36
DATA and INFORMATION
  • DATA - Raw, unprocessed facts, not very useful
    in their current form
  • INFORMATION - The result of processing the
    DATA - more useful to us

37
How Computers Work
  • Processes data into information
  • Uses hardware software
  • Operates by performing
  • Input - Output
  • Processing - Communications
  • Storage
