Classification of Motherboard
Integrated Motherboard
Non-Integrated Motherboard
Motherboard and It’s Classification
Integrated Motherboard

• Components are in built in the

motherboard.

• Designed for simplicity.

Draw backs

• When one component in the

board is broken or stops
working you have to replace
the whole board

• Cheaper to produce but more

expensive to repair.

Motherboard and It’s Classification
Non-Integrated Motherboard

• The major assemblies like Video

circuitry, disk controllers, and
accessories are installed on the
Computer as expansion cards.

• Can easily Identify the

Non-integrated motherboards
by their expansion slots usually
occupied by one of the components.

How Motherboards Work

• A. Three primary characteristics
• 1. Form factor determines size of the motherboard and general location of the parts.
• 2. Chipset defines the type of processor and RAM supported.
• 3. Built-in components determine functionality and expandability of the system.
• B. The motherboard contains traces or wires through which the data and commands flow. Motherboards typically have traces on multiple layers of the board.

How Motherboards Work

• C. Form factors

1 What is a form factor?

a) Industry standardized shapes and layouts

b) Allows standardization of cases and power supplies. Cases are designed so that when the motherboard is properly mounted, motherboard connectors are available externally.

2. AT motherboards are old-style form factors and currently obsolete. Each features a large keyboard plug and two connectors called P8 and P9 from the power supply.
