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.
