What On Earth is a Mainframe?

Looking for a "Mainframes for Beginners" book? Need to learn about z/OS fast? Then this is the book you need.

This is the perfect introduction to IBM System z Mainframes and z/OS. Avoiding technical jargon, it gives you the basic facts in clear, light-hearted, entertaining English. You'll quickly learn what Mainframes are, what they do, what runs on them, and terms and terminology you need to speak Mainframe-ese.

But it's not all technical. There's also invaluable information about the people that work on Mainframes, Mainframe management issues, new Mainframe trends, and other facts that don't seem to be written down anywhere else.

What On Earth is a Mainframe is the closest you'll get to a "Mainframes for Dummies" book.

Programmers, managers, recruitment consultants, and industry commentators will all find this book their new best friend when trying to understand the Mainframe world.

David Stephens saw his first Mainframe in 1989, and can't seem to get away from them. After graduating with an Engineering degree from the University of Tasmania, he spent six months working as a Mainframe Network Operator before moving to z/OS Systems Programmer. Since then David has amassed over eighteen years of Mainframe technical experience - working on almost every aspect of managing and operating Mainframes. He also has six years experience working in Systems Software Development and Level 3 Software Support for IBM. 

When not working on Mainframes, David loves to travel the world, go walking for days in the wilderness, scuba dive, or some combination of these. He'll also happily drink your red wine collection dry. 

David currently works as a Systems Programmer Consultant with Longpela Expertise. He lives in Perth, Western Australia.
