前言
一种比较势利的??观点来划分计算机，其实是根据大小。我们用的笔记本、台式机其实应该叫做 minicomputer
计算机进化史
按照从大到小
Mainframes and super computers are the biggest computers – million dollar machines, as big as a refrigerator or bigger. An example is the IBM model 390.
Minicomputers are large, powerful machines which are often found at the centre of networks of “dumb” terminals and PC’s. For example, IBM’s AS/400. A definition that was used in the past, was that minicomputers cost between $10,000 and $100,000.
Workstations are very powerful user machines. They have the capacity to execute technical/scientific programs and calculations, and typically use a UNIX variant or Windows NT as their operating system. Workstations used to be equipped with powerful RISC processors, like Digital Alpha, Sun Sparc or MIPS, but today workstations can be configured with one or more of Intel’s more powerful CPU’s.
The PC is the baby of the family: Small, cheap, mass-produced computers which typically run Windows and which are used for standard programs which can be purchased anywhere.
但是有趣的是，PC这个计算机家中的baby长大了，其性能不比Workstations 、Minicomputers差多少。
