Abstract

In its most basic form, a computer is just a programmable processor, with some means for input and output of the treated data. More complex computers have a far more complicated architecture, with special units for contact with the environment, such as keyboards, displays, communication line interfaces, readers for special media like USB and DVD, etc. They often also contain large data storage areas, such as an internal hard disk. Today, computers are often connected via networks, such as specialized local networks, as in a car, or completely general networks like the Internet. The distinction between a single computer and a cluster of computers becomes more and more blurred. The shared property of all these diverse systems is that they are all technical systems for the treatment of information. Thus, today we often talk of a more general concept of information technology (IT) systems.
