PCs and Mainframes

Paper Summary:

The paper explains that not only can PCs do almost everything that the larger mainframes can do, but also they can do it at a significantly lower cost. The author points out that there are legitimate uses for the higher mainframe power, especially when a company or institution needs to support hundreds or thousands of users at the same time. The paper relates that, even if many PC computers are linked together with the server, they still cannot compare the I/O capability of the mainframe, which makes all the difference in certain applications.

From the Paper:

"In addition to the advantages of a mainframe regarding reliability and speed is something known as "parallel sysplex." Parallel sysplex is a way of writing serial code that can work across more than one mainframe. Again, this may not be useful for all purposes, but in those industries that demand more functionality in their computer power, the mainframe continues to tower over the PC."
