How many floating point registers are there in IBM 360?
Short precision addition or subtraction takes 3.81 microseconds; long precision takes 6.32 microseconds. Operations are executed in any of four 64-bit floating point registers.
What generation is IBM 360 computer?
Third generation computers
Third generation computers. The computers introduced in the mid 1960s, such as the IBM 360 family, were called “third generation” computers. Third generation computers were important because each computer in a family had the same architecture.
How much did an IBM 360 cost?
The IBM 360 was the “jewel” of the office Once on the market, the IBM 360 didn’t come cheap. “The models cost around $2 million, so most businesses rented them for around $20,000.” But the price was worth it.
What is the significance of the IBM 360?
The most significant contribution of the IBM System/360 to the world of computing was its commitment to compatibility. It was the first product family that allowed business data-processing operations to grow from the smallest machine to the largest without the enormous expense of rewriting vital programs.

What are the limitations of OS 360?
OS/360 MFT (Multiple Programming with a Fixed Number of Tasks) could run several programs but only after partitioning the memory required to run each; its limitation was that if one program was idle, memory devoted to it was inaccessible by other programs.
How many general purpose registers do IBM 360 machine have?
General Purpose Registers The System/360 architecture calls for sixteen 32–bit registers, numbered 0 through 15.
How many various data formats do IBM 360 machine have?
The IBM System/360 is a 32-bit machine with byte addressability and support for a variety of data types: byte, halfword (16 bits), word (32 bits), doubleword (double-precision real), packed decimal, and unpacked character strings.
How much did the IBM 360 cost?
Once on the market, the IBM 360 didn’t come cheap. “The models cost around $2 million, so most businesses rented them for around $20,000.” But the price was worth it. “The IBM 360 was a major status symbol.”
Can a computer work without a software?
You can, but your computer would stop working because Windows is the operating system, the software that makes it tick and provides a platform for programs, like your web browser, to run on. Without an operating system your laptop is just a box of bits that do not know how to communicate with one another, or you.
Which technology is used in the machine IBM 370?
Monolithic System Technology
All models of the System/370 used IBM’s form of monolithic integrated circuits called MST (Monolithic System Technology) making them third generation computers.
How much RAM does a mainframe have?
They can provide up to 12 parallel 650 MHz processors, 32 GB memory, and several terabytes of disk storage. Compare that to a typical PC with a single 500 MHz processor, 64 MB of memory, and 10 GB of disk storage!
What is IBM System 370 architecture?
The System/370 Extended Architecture (S/370-XA), first available in early 1983 on the 3081 and 3083 processors, provided a number of major enhancements, including: expansion of the address space from 24-bits to 31-bits; facilitating movement of data between two address spaces; and a complete redesign of the I/O …
