CHAPTER 1.1

The central components of mainframe computer systems are processors. MVS runs on processors that are members of system/360-370 family.MVS is nothing but "MULTIPLE VIRTUAL STORAGE" this we will discuss in another chapter because it is a vast subject. Processors of mainframes are frequently asked interview questions so i am discussing it earlier. So please be careful while telling the answer in interviews here is it i will explain.

  • SYSTEM/360-370 FAMILY INCLUDES
  • SYSTEM/360 MODELS IN 1960'S
  • SYSTEM /370 MODELS OF EARLY 1970'S & 3030 MODELS OF LATE 1970'S
  • THE 4300 AND 3080 MODELS OF EARLY 1980'S & 3090 MODELS OF LATE 1980'S
  • RECENT MEMBERS OF THIS FAMILY ARE ES/9000,S/390 AND Z-SERIES SYSTEMS.
Some installations still run under 4300,3080 and 3090 systems.These processors which we discussed above are popular processors.

I think now you are able to explain the answer.
