Contrast Mainframes and Personal Computers Overview Mainframes and personal computers have evolved over the years but their core functions have stayed the same. The mainframe is used connect multiple users for large organizations while personal computers are generally used for a single users. The more drastic changes for mainframes and personal computers have been speed and size. Mainframes use to be the size of buildings. Now they are the size of a textbook. Personal computer ’s origins

Mainframe/PC Evolution The evolution of mainframe computing to personal computing began with the invention of the mainframe for businesses and government use. The Personal Computer (PC) evolved from companies wanting the same information from scaled down version of the mainframe and dumb terminal. Though they both consist of data storage‚ processors‚ input and output devices. However‚ they have their differences. Mainframes The mainframe was invented in the 1950’s. One of the first mainframes

Mainframe Operating Systems At the high end are the operating systems for the mainframes‚ those roomsized computers still found in major corporate data centers. These computers differ from personal computers in terms of their VO capacity. A mainframe with 1000 disks and millions of gigabytes of data is not unusual; a personal computer with these specifications would be the envy of its friends. Mainframes are also making something of a comeback as high-end Web servers‚ servers for large-scale
