The purpose of this paper is to compare and contrast PCs and mainframes. The first part of the paper will compare the mainframe and the PC to each other. The second part of the paper will discuss the benefits of the mainframe versus the PC.

Until the 1980s, the traditional thought was that mainframes would be the primary source of computing power that companies needed to maintain data and store records (Bennett, 2000). PCs were still in their infancy stage and were running on 386 and 486 processors that were not capable of performing anywhere near the performance levels of a mainframe. If access was needed, someone had to sit at a computer screen that was built into the mainframe and enter a series of codes. Throughout much of the '90s, many in the high-tech industry thought the big machines had outlived their usefuln

In conclusion, I believe that mainframes have not outlived their usefulness and are still an integral part of mission critical systems. Mainframes perform more tasks and at a faster rate than an ordinary PC. PCs are mainly utilized for processing, spreadsheets, and other less demanding calculations. Mainframes can handle hundreds or thousands of users at one time and perform tasks or calculations at a faster rate than an ordinary PC.

ess (Bennett, 2000). There was a renewed interest in moving away from mainframe computing to smaller and less costly mini-computers with the introduction of the first Pentium processor in 1994. As smaller, less costly mini- and mid-range computers became more and more powerful, they could do much of the work companies previously bought mainframes to do, and at a fraction of the cost (Bennett, 2000). Mainframe dominance began to come
