What is the full form of IBM 360?
IBM System/360
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.
What type of computer is IBM S 390?
The IBM System/390 is the discontinued fifth generation of the System/360 instruction set architecture. The first ESA/390 computer was the Enterprise System/9000 (ES/9000) family, which were introduced in 1990. These were followed by the 9672 CMOS System/390 mainframe family in the mid-1990s.
When did the IBM 370 Model 145 come out?
IBM System/370 Model 145 Manufacturer International Business Machines Corporat Product family System/370 Generation Third Release date September 23, 1970 ( 1970-09-23)
What kind of memory does the IBM 370 use?
IBM System/370 Model 145 uses silicon memory chips, rather than the magnetic core technology. Monolithic circuitry also is used throughout the Model 145’s central processor to perform all of the system’s arithmetic and logic functions.
How much does it cost to rent an IBM 370?
Monthly rental for typical configurations of IBM System/370 Model 145 will range from about $14,950 (with 112,000 characters of main memory) to $37,330 (512,000 characters), with purchase prices ranging from about $705,775 to $1,783,000. Initial customer shipments will be scheduled for late next summer.
What kind of memory does the IBM Model 145 have?
The use of monolithic memory technology, with its very high circuit density, allows IBM to offer Model 145 users more than a half-million characters of high-speed storage in about half the space that would be required by core planes for an equivalent amount of memory.
