Mainframe computers are large, powerful machines that big organizations use to process lots of data and handle multiple users and applications at the same time. They're essential for tasks like handling transactions and managing data for large businesses. Examples are IBM zSeries and Unisys ClearPath.ChatGPT can make mistakes.

State two purposes of mainframe computers.

The business computing world has gone through several computer cycles. For example, years ago we used mainframe computers with “dumb” terminals that didn’t do much processing on their own and, instead, relied entirely on the mainframe server to work. We then moved to individual and personal computers, each running their own separate programs and doing their own processing. This was followed by the use of central servers that all computers pointed back to for file storage, applications, processing, and databases. Today, it seems that we have almost gone full circle and returned to “dumb” terminal functionality with systems, such as cloud computing and mobile apps. Do you agree or disagree with this last statement? How does the use of cloud computing services resemble “dumb” terminal functionality? Where does it differ?
