Microcomputers are programmable electronic information processing machines whose controlling circuits are combined into one solid state (entirely nonmechanical) component called a central processing unit (CPU). Microcomputers can perform complex...

Before the introduction of the personal computer or microcomputer to the general market in the 1970s, computers were physically large, complex, often unreliable, and expensive pieces of machinery. However, they operated in much the same way as they do...

Although there is no single definition, a microcomputer (in the 1970s and 80s sometimes shortened to micro[2]) is most often taken to mean a computer with a microprocessor as its CPU. Another general characteristic of these computers is that they occupy...

Microcomputers have evolved rapidly since their commercial introduction in 1976. Their popularity has been spurred by their strong computing power, their inexpensiveness and their simple operation. Developments in miniaturization have further increased the popularity of microcomputers, since they can now perform as efficiently as...

The learning experience of creating an audit protocol governing main-frame and expense computer systems is discussed. After establishing the specific objectives of the consulting task, the list of priorities includes: the identification of compliance level of micro users to existing guidelines and controls involving...
