245 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
255 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
265 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
275 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
285 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.
