Connectivity
The type of connections vary from computer to computer and is critical in the connection type required to external peripherals and via bluetooth/wireless.

Screen Size
Important for laptop, tablet and all-in-one computers, the screen size determines the type of work you will be doing and what functions to operate.

Energy Use
The power or battery of a desktop and laptop computer determines the amount of energy used/saved for sustainability and reducing cost.
