Google is your friend. Google system z and see what you can learn. And mainframes were around more than 20 years before PCs.

Also, look here at our sister site.

"Mainframe" computers first appeared around 1950. "Mini" computers first appeared around 1960. "Personal" computers first appeared around 1980.

If you cannot be bothered to do any research, why should we do your research for you? Use Google or Bing or whatever and start learning something on your own. The cheapest IBM mainframes run about $75,000 USD (depending on what you're wanting) and the cost can get up well over 10 million US dollars. Most companies buying a mainframe do so through an IBM partner and not directly from IBM.

Mainframe computers are used by something like 71% of the Fortune 500 companies. The last research I saw indicated that if you use an ATM machine anywhere in the world, there is a 95% chance that your data goes through a mainframe at some point. 96 of the top 100 banks in the world, 23 of the top 25 US retailers, and 9 out of 10 of the largest insurance companies in the world use system z. Mainframes are used in cloud computing, manufacturing, financial systems, inventory, human resources, and pretty much every area a company can need a computer for.
