The motherboard is the fundamental physical component in computers.
It generally contains:
CPU
Spaces for memory
Connectivity to power
Additional slots for system expansion
The entire process of using a computer begins and ends with the motherboard.
Motherboard Sizes and Layout
Different sizes available depending on requirements.
Basic layout includes:
CPU slots
Memory slots
Expansion slots
Variation in the number of expansion and memory slots based on motherboard size.
Power connectors are standardized for compatibility.
Choosing a Motherboard
Factors influencing motherboard choice:
Size of the computer case
Future expansion needs
Required airflow for system cooling
Over 40 different sizes/types exist, but only 2-3 are very popular.
Compatibility with different cases, with features and space being key differences.
Motherboard Application Examples
Full-size vs small form factor devices:
Full-size desktops have ample room for large motherboards.
Small form factors require smaller motherboards.
ComptiA exam focuses on selecting the right motherboard for specific tasks like media centers or thin clients.
Popular Motherboard Families
ATX Family
Standard in desktop computers, offering plenty of expansion and memory slots.
Advanced Technology Extended (ATX) standard since 1995.
Recent updates include 20-24 pin power connectors, with additional CPU power.
Example: Asus Maximus 7 Hero ATX motherboard.
ITX Family
Created by VIA Technologies in 2001 for small form factors.
Designed for small cases but can fit in larger ATX cases due to compatible screw holes.
Ideal for media centers and areas where space is limited.
Conclusion
Understanding the differences and applications of ATX and ITX motherboards is crucial for making informed decisions on computer builds and configurations.
Applying this knowledge to real-world scenarios enhances the ability to select the appropriate motherboard for specific needs and environments.
