PC Networking: How It All Began

Computing and the advances that led to the modern personal computer go as far back as the human race itself, way back to devices such as the abacus (500 B.C.) and the Jacquard loom (a nineteenth-century mechanized loom that used a series of punch cards to create a particular weave). While our focus in this book is the networking of the personal computer, a little background information on the evolution of modern computing makes sense. To start, we can jump ahead to the 1950s.

Mainframes and Miniframes

Although there were a number of super computers created prior to 1950, the early mainframe market (which was not all that huge because of the size and cost of these computers) was dominated by International Business Machines (IBM). The IBM Model 701, which used vacuum tubes, was created in 1952. IBM also led the field in mainframe innovations and introduced the first computer disk storage system, as well as developed the FORTRAN programming language.
