使用する際の注意点

• Originally, the term personal computer was broadly applied to a broad spectrum of computers for personal use (including for example the Apple II), distinguishing such computers from mainframes and specialized microcomputers (such as those designed primarily for electronic games or controlling equipment). From the launch of the IBM Personal Computer in the early 1980s, the term became more often used specifically in subsense 1.1, and by the end of the 1980s, in subsense 1.2, in particular its acronym PC.

• Since then, sense 1.2 has become even much vaguer with the evolution of hardware and software. The term personal computer is often used for desktop computers or non-dedicated servers that may run multi-user software and be accessed by more than one person (for example: by means of a local area network). In the previous decades, the appearance of numerous models (and types) of computers and the two subsenses has made this term polysemous and vaguer, causing more precise terms (such as desktop, laptop, home computer, Linux workstation) or term combinations to be often preferred nowadays.
