Unit IV: Peopleware

Peopleware — the human element of computing — is considered the most important component of any computer and communications system. Without people, no hardware would be designed, no software would be written, and no output would carry any meaning. As ICT continues to evolve, a wide range of professional roles has emerged to design, operate, maintain, and use these systems.

Most professional ICT work falls into three broad areas: Information Systems / Information Technology, Computer Systems Engineering, and Computer Science.
