Hardware is the physical part of a computer — anything you can touch andanything you can see. The computer chassis, themonitor, the keyboard, themouse — that physical stuff is hardware.

Airflow
Components can get very hot, and good airflow is needed to get that heat away from thecomponents.There are three main airflow models :Negative Pressure―sucking all the hot air out of the case.Positive Pressure―pushing hot air out of the caseEqualised Airflow―equal air intake and exhaust.
Power Supply
The power supply is the heart of the computer.It provides all of the other components in the computer with power.

Motherboard
A motherboard is also called a main board or just “The Board”.
The First Motherboard―Apple II (1977)

Motherboard Size
Standard ATXHaving six or sevenexpansion slots and often have more SATA and IDE ports than on a Micro-ATX motherboard.
Micro-ATXThe only real differencebetween ATX and Micro-ATX motherboards is the number of expansion slots and the amount of space on the boards.
Mini-ITXMini-ITX motherboardsusually have very few SATA ports, rarelyhave an IDE port, and typically only one expansion slot.
ChipsetsComponents which are connected to themotherboard are controlled and connected by the chipset.This usually comprises of a northbridge chip and a southbridge chip.
Chipset Map
NorthbridgeThe northbridge chip allows the CPU, RAM and Graphics Card(s) (via PCIExpress lanes or, before that, AGP lanes) tocommunicate between each other.The northbridge no longer exists as a chip on the motherboard on newer systems; instead the PCIExpress and RAM controllers have been incorporated into the processor itself.
SouthbridgeThe southbridge is responsible for thecommunication between the other components, external devices, audio and the network.
