Handheld & Personal Computers History

History of the PC (personal computer), handheld computers and PDA history. A personal computer (PC) is a complete microcomputer based on a microprocessor, a small semiconductor chip. Along with other integrated circuits, it is designed for a single user and usually includes a keyboard and monitor. Two of the chief measures of computing power are computer memory size and processing speed. The processing speed of PCs is commonly specified by the speed of the electronic clock that controls internal operations. Early PCs had clock speeds of one or two megahertz (MHz), but speeds of 900 MHz or more are possible in modern designs. The unit of memory is the byte.
