Section 1 – Mainframe Computing
Out of all the technologies leading up to what we know as cloud computing now, Mainframes maybe the closest thing we have to modern day Cloud Computing although it’s several decades old. We say this because it’s a large centralized infrastructure and many clients connect to it with almost all the data processing happening on the Main Frame itself.
What is a Mainframe?
A Main Frame is a massive computer capable of running the operations of a large entity such as:
- large business
Mainframes were designed to run the operations of a large business or government and processed all the computations on is own hardware while allowing terminals to connect to it to interact with the applications and data. The terminals were usually a single color and did not computational work on their own. They were often referred to as dumb terminals as they were really just a window into the applications running on the mainframe.
Examples of Mainframe Computers
Mainframe computers were made by several firms but IBM is a notable Mainframe manufacturer during the Mainframe era. ‘
