System/360 - A family of computers.
Unlike past practice, IBM created an entire line of computers (or CPUs) from small to large, low to high performance, all running the same command set (with two exceptions for specific markets). This feat allowed customers to use a lower cost model and then upgrade to larger systems as their needs grew — without the time and expense of rewriting software. Many models (e.g. the 360/30) even offered the option of microcode emulation of the customer's previous computer (e.g. the IBM 1401 or the IBM 1620) s ...

System/360 - Key features of lasting impact.
The System/360 introduced a number of industry standards to the marketplace, such as:
The 8-bit byte (against financial pressure during development to reduce the byte to 4 or 6 bits)
Byte-addressable memory (as opposed to word-addressable memory)
32-bit words
Two's complement arithmetic
Segmented and paged memory
Commercial use of microcoded CPUs
The IBM Floating Point Architecture (until superseded by ...
