There are vents on the forward-facing, opposite, upper, left, right side panels of the event to let out hot air of the instance. Although in almost durable PC cases require bolts to hold gears together later this was modified to hold components together by using snap in the plastic railings and further methods so that gathering and alteration of workstation hardware became less time consuming. Using plastic screws made manufacturing cheaper also.

The most important component that is housed in the computer case is the motherboard which includes essential components.
In the computer field people talk of applications or apps. An application is a kind of a software that is used to accomplish specific tasks. Applications for a desktop or a laptop computers are titled desktop applications while applications used in mobiles are titled as mobile apps.
