Introduction to Computers

• Lesson 4B

2
Central Processing Unit

• The computers primary processing hardware, which
  interprets and executes program instructions and
  manages the functions of input, output, and
  storage devices

3
Architecture

• A processors performance is dictated by its
  internal design, or architecture

4
Microcomputer Processors

• Intel
• Advanced Micro Devices (AMD) processors
• Motorola processors
• RISC
• Parallel processing

5
Extending the Processors Power to Other Devices

• Serial and parallel ports
• Specialized expansion ports

6
Examples of Specialized Expansion Ports

• SCSI
• USB
• IEEE 1394 (FireWire)
• Musical Instrument Digital Interface (MIDI)

7
Expansion Slots and Boards

• Allow users to adapt, or configure, the PC to
  their own needs

Plug and Play

• The Plug and Play standard makes it easier to
  install hardware via an existing port or
  expansion slot
