Controls, sometimes referenced as controllers, are software programs or hardware devices that manage or direct data between two entities. This could, therefore, mean the term controllers could be connected to a number of elements, examples include microchips, cards or external hard drives.
In its basic definition, a controller, in the context of computing, is either something or someone that manages communications between two systems to allow for the exchange of data. A particularly useful tool for businesses and professionals.
There are multiple controllers within the IT industry, and professionals’ knowledge of them will depend on their specialist skills and the tasks they need to complete using them. However, all IT professionals will require the use of a controller to complete their works.
