Operating Systems: Crash Course Computer Science #18

So as you may have noticed from last episode, computers keep getting faster and faster, and by the start of the 1950s they had gotten so fast that it often took longer to manually load programs via punch cards than to actually run them! The solution was the operating system (or OS), which is just a program with special privileges that allows it to run and manage other programs. So today, we’re going to trace the development of operating systems from the Multics and Atlas Supervisor to Unix and MS-DOS, and take at look at how these systems heavily influenced popular OSes like Linux, Windows, MacOS, and Android that we use today.

What makes an OS perform well or faster?

I studied computer science and was supposed to learn all of these at school but hated it back then. Because they didn't tell it like Carrie Anne.

"Half of a computer's memory just to run the OS"

So, Windows Vista?

"fasta, and fasta, and fasta…"

actually, os is more like a library

These days, if you have 2-8GB of memory and are running the latest version of Windows, you can also find that half of your memory has gone to your OS.
