-[PS/2] was originally the name of a new range of [IBM] computers
which were infamous for being the only
[IBM] compatiable not to be
[IBM] compatiable even though
they were made by
[IBM]!
+[PS/2] was originally the name of a new range of [IBM] [PC]s
which were not
[IBM] [PC] compatible.
[IBM] tried to reclaim the [PC] market from the clones with this move. Instead, it cost them whatever dominance
they had left. Nowadays the term is used to refer to the compact connection ports for keyboards and mice introduced with the
[IBM] [PS/2] line of computers, as opposed to the much larger XT/AT ports for keyboards and the serial connectors for mice. Now largely replaced by [USB] peripherals.
-In retrospect this was actually a good thing as then software became abstracted from the hardware which opened up increasing performance for PCs and scope for further evolution. For example in the GoodOldDays your game may have been unplayable
on a newer machine as it would be twice as fast if the processor was twice as fast...

-Nowadays it is used to describe the connection for keyboards and mice. Keyboards and mice were originally plugged into bigger ports (XT/AT and serial respectively) and the
[PS/2
] introduced the newer, smaller ports.

-Now largely replaced by
[USB] peripherals although [GRUB] (my version anyway)
still needs a
[PS/2] keyboard
to make selections which can be annoying on
the occasion that I want to use
[Windows
].
+Depending
on [BIOS
] support for
[USB] you may
still need so-called "legacy"
[PS/2] input devices
to interact with your BootLoader and
the [BIOS
] setup
.
