A computer system is a system of hardware and software that is able to take a set of inputs, process them and create a set of outputs. Any device capable of this can be classified as a computer system, so this definition includes phones, almost all electrical appliances and even simple devices such as calculators.

There are a lot of computers in the world. A lot of important things are done with computers, like storing money and controlling nuclear weapons The internet exists, which wouldn't be the case without computer systems. So many tasks in the modern world are done with computers, indeed it is unlikely that the world as we know it could exist without computers

There are people who rely on computers to live. Important tasks like flying planes and controlling nuclear weapons are done with computers. If computers fail, often systems that rely on them are damaged. In the modern world, this means most systems.

The need for adherence to professional standards

It is important that computers should be compatible with each other, so that any new software or hardware developed can be used in most systems. To this end, professional standards are put in place to restrict the development of new hardware/software to conform as much as possible to existing standards. For example, USB is used very commonly as a means of connecting devices, as most devices are compatible with USB connections.
