Computer systems and software are an integral part of the world in which we live. Few areas of our working and personal lives remain untouched by technology. Well-engineered, reliable and usable systems are crucial to the survival of virtually all organisations today, to the functioning of the global economy and even for our entertainment.
Computing is an interdisciplinary subject, with historical roots in mathematics, physics and electronics. It provides routes into many different careers.
People who can build and maintain computer systems and software will be in continual demand in the future.
IT professionals have a crucial and challenging part to play in the effective application of computing technology to achieve effective processing of information. The ever-growing list of activities to which computing is applied - and the importance of information processing generally - have created excellent employment opportunities for those who obtain appropriate qualifications in IT.
Most professional IT work can be classified into three broad areas:
Individuals working in the information systems area are engaged in designing and implementing systems which collect, validate, store and report information from customers or other business transactions.
IT professionals in the computer system engineering field are involved in the application of computers in a wide range of industrial control problems. Computer systems of this type require the design of special computer hardware from supplied components, and the writing of specialised software to interact with the industrial control system.
The third main area is the field of computer science, where graduates may undertake research into the design of specialised hardware or software.
