The software
operating system
A contester to the micro computer was IBM’s
so-called Personal Computer or PC although is was much
pricier and did not find it’s way into normal homes straight away. was a much began to change as the
new IBM PC (PC for Personal Computer) entered the market. The IBM PC used a software operating
system. This had to load on startup, but made it easier to update - simply because you did not need
to buy a completely new piece of hardware. The OS (for Operating System) was called MSDOS, this was
short for Micro-Soft Disk Operating System (yes, they used a dash in their name in the early days).
The code was based on the UNIX operating system although greatly simplified.
