How components connect.
WHAT THE MOTHERBOARD DOES
Connects every component, and provides the paths between them.
WHAT A BUS IS
A shared path carrying data between components.
WHAT EXPANSION SLOTS PROVIDE
The ability to add capability: graphics, storage controllers, network cards.
WHAT DETERMINES COMPATIBILITY
The processor socket The memory type The form factor Available slots and connectors
WHY THAT MATTERS
Components are not interchangeable across generations.
WHAT TO CHECK BEFORE ANY UPGRADE
What the board supports, by its documentation rather than assumption.
WHAT LIMITS UPGRADES
Maximum supported memory Available slots Power supply capacity Physical space
WHAT FIRMWARE ON THE BOARD DOES
Initialises hardware and provides settings.
WHAT TO KNOW ABOUT UPDATING IT
It can resolve compatibility problems, and a failed update can render the board unusable.
WHAT TO DO ABOUT THAT
Update only with reason, following instructions exactly, on stable power.
