Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.
