Pros and Cons of the Mainframe
There is an old saying that “You can’t teach an old dog, new tricks”. This stays good for Mainframe computers as well.
Mainframe can process humungous data in a best possible way. But it doesn’t provide you that visual and graphical user experience that a normal personal/mini computer provides today .Moreover, Mainframe computer doesn’t run on the click of a mouse. You have to give command for each operation. It comes with a black screen of 24X80 character (using 3270/3278 terminals) which is not fancy like others.
When we talk about Mainframe, Compatibility is also one of many major features. No other computer system/architecture can claim as much continuous, hick-up free evolutionary improvement, while maintaining compatibility with previous releases.
