These questions are hardly basic, and would require way too much to answer than could reasonably be provided in this forum. I would suggest that you read IBM's "ABC's of z/OS Systems Programming", which is a ten-volume collection of books, to help you answer some of your questions.

Here is a link to Volume 1: www.redbooks.ibm.com/redbooks/pdfs/sg246981.pdf

Hai,

MAINFRAME is a very big system means not one. It includes many processors like...

It executes more than million lines per second.

It provides more security and Access is very fast.


Already many applications are developed in Mainframes. They can migrate that applications to new technologies. But, it will take more time and very cost. They may loss data while migrating to some other technology.

That's why they are keeping the applications in mainframes itself....

Personally, I shun the use of the term "mainframe" and instead use the term "z/OS Server".

An IBM mainframe is a computer running z/OS, Linux, VM, or VSE.

Important features are:

1. Maximum reliable single-thread performance.
2. Maximum I/O connectivity.
3. Maximum I/O bandwidth.
4. Heavy-duty reliability.

* Mainframe is an industry term for large computer

* Mainframes used to be defined by their size, and they can still fill a room, cost millions, and support thousands of users. But now a days, mainframe can also run on a laptop and support two users. So today's mainframes are best defined by their operating systems: Unix and Linux, and IBM's z/OS, OS/390, MVS, VM, and VSE.
