- Nevertheless , they can be divided into several categories on the basis of cost and performance : the personal computer or microcomputer , a relatively low - cost machine , usually of desktop size ( though “ laptops ” are small enough to fit in a briefcase , and “ palmtops ” can fit into a pocket ) ; the workstation , a microcomputer with enhanced graphics and communications capabilities that make it especially useful for office work ; the minicomputer , generally too expensive for personal use , with capabilities suited to a business , school , or laboratory ; and the mainframe computer , a large , expensive machine with the capability of serving the needs of major business enterprises , government departments , scientific research establishments , or the like ( the largest and fastest of these are called supercomputers )
然而，根据成本与性能，它们可分为几类：个人计算机或微型计算机，一种成本相当低的机器，通常只有桌面大小（尽管“膝上型计算机”小到能够放入公文包，而“掌上型计算机”能够放入口袋） ；工作站，一种具有增强的图形与通信能力、从而使其对于办公室工作特别有用的微型计算机；小型计算机，一般就个人使用而言太昂贵，其性能适合于工商企业、学校或实验室；以及大型机，一种大型的昂贵机器，具有满足大规模工商企业、政府部门、科研机构或者诸如此类机构需要的能力（其中体积最大、速度最快的称为巨型计算机） 。
