What was the IBM 360 used for?
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific.
How much memory did an IBM 360 have?
| System/360 | |
|---|---|
| Manufacturer: | International Business Machines |
| Clock Speed: | 1 μsec (Model 30) 60 nsec (Model 91) |
| Memory Speed: | 2 μsec (Model 30) 780 nsec (Model 91) |
| Virtual Address Size: | 24 bits (optionally 32 on the Model 67) |
Which generation computer is IBM 360?
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.
Which instruction format of IBM 360 uses index register?
Instructions in the S/360 are two, four or six bytes in length, with the opcode in byte 0. Instructions have one of the following formats: RR (two bytes). Generally byte 1 specifies two 4-bit register numbers, but in some cases, e.g., SVC, byte 1 is a single 8-bit immediate field.
How many general purpose registers are there for IBM 360 and 370?
General Purpose Registers The System/360 architecture calls for sixteen 32–bit registers, numbered 0 through 15. While these might be called “general purpose”, a few of the registers have dedicated uses. Registers 0 and 1 can be used as temporary registers, but calls to supervisor routines will destroy their contents.
Who is the inventor of IBM 370?

Who invented IBM 4341?
the intermediate systems group
The IBM 4341 Model 2 was developed by the intermediate systems group, and manufactured by SPD, in Endicott. Subsequent processors had development and manufacturing activities in Endicott, Havant, Boeblingen, Valencia, and Sumare.
What type of computer is IBM System or 360 Model 195?
System/360 Model 195, announced today, is the most powerful computer in IBM’s product line. It uses monolithic circuits, has a high-performance buffer memory and can perform many functions simultaneously.
What was the name of the IBM 7030 computer?
IBM called their machine “STRETCH” or, more formally, the “IBM 7030”. By about 1958, the lab ordered a STRETCH as well; the LARC was late for delivery. The LARC was, indeed, delivered about two years late. The STRETCH was also late, but only by a few months [1].
When did the IBM 7030 Stretch come out?
IBM did a deal with Los Alamos for a similar machine about two years later than the LARC contract. IBM called their machine “STRETCH” or, more formally, the “IBM 7030”. By about 1958, the lab ordered a STRETCH as well; the LARC was late for delivery.
What was the name of the IBM Stretch computer?
IBM built about ten STRETCH systems; one was a component of the Harvest that went to NSA. The STRETCH missed its original performance targets and was upstaged by the IBM 7090 that had aggressively adapted the STRETCH transistor technology and 2-microsecond core memories [3].
