What is IT and why do we need it? 
Basically, IT or Information Technology is the combination of Hardware (computer systems) and Software (Applications) which manage the information. That information is processed by the hardware and stored locally or in a Central location.

A computer system (or desktop computer) pretty much consists of a monitor, a main box (containing the hard drive, memory, mother board and DVD/CD drive) as well as a keyboard and mouse. An alternative to this is a laptop, which is a much smaller version of a desktop computer and contains all of the above components in one portable unit.

Both of these systems do have their benefits depending on what it is that you need. A desktop computer would obviously be confined to just the one spot in the office, however the laptop is very flexible and mobilized. Being a battery-run machine it can be carried if needed both around the office and outside of it.

Despite their differences, each of these systems requires software to function. Without the other both hardware and software are basically rendered useless.
