In this chapter, you will learn how to identify personal computer components, including the following:

  • Motherboards
  • Processors
  • Memory
  • Ports and cables
  • Cooling systems

Identifying Components of Motherboards

Motherboards (system board) The spine of computer

Types of System Boards

  • Nonintegrated System Board
  • Integrated System Board

System Board Form Factors (Design)

  • 1. AT
  • 2. Advanced Technology Extended (ATX)
  • 3. Micro ATX
  • 4. New Low-profile Extended (NLX)
  • 5. Balanced Technology Extended (BTX)

(AT)

2-Advanced Technology Extended (ATX)

Main changes from AT design

  • More cooler (Airflow)
  • More space for expansion card
  • Power switch
  • Power connection to the motherboard

2-Micro ATX(μATX)

  • Quantity of memory modules,
  • Quantity of expansion slots
  • ATX chassis bays
  • Integrated peripherals
  • Backward-compatible with ATX.

3-New Low-profile Extended (NLX)

Low Profile eXtension (LPX)

  • originally developed by

Western Digital in 1990 New Low-profile Extended (NLX)

  • proposed by Intel and

developed jointly with IBM, DEC, in 1997

use riser card in the center of the motherboard to reduced vertical space

slide-33
SLIDE 33

Balanced Technology Extended (BTX)

By lining up all heat-producing components between air intake vents and the power supply’s exhaust fan Compatibility with ATX products The heart of this design is an increase in airflow available to the components that produce the most heat, specifically the video card and CPU. With improved airflow the system will be able to run cooler and because of the added efficiency, quieter.

proprietary design motherboard.

  • There are other motherboard designs, but

Some manufacturers (such as Compaq and IBM) design and manufacture their own motherboards, which don’t conform to the standards.

  • This style of motherboard is known as a

proprietary design motherboard.
