Windows' ancestor is MS-DOS, a text-based OS Microsoft released in 1981. We're going to briefly review each of them individually and later on compare all of them to identify their differences.
#HOW TO CODE UNIX ON MAC ANDROID#
And talking about mobile devices, around 75% run Android (which uses the Linux kernel) and 25% run IOs (which is Apple's mobile OS). Regarding servers, around 80% run GNU/Linux and 20% run Windows.
#HOW TO CODE UNIX ON MAC WINDOWS#
In the modern days, when speaking about personal desktop/laptop computers, the three most used operating systems are Microsoft Windows (with around 80% market share), Apple MacOS (with around 15% market share), and GNU/Linux based OSs (with around 3% market share).

This channel has an incredible crash course series about computer science too, I definetely recommend it! ) The Three Main OSs If you're interested in a more detailed explanation of how OSs work and their history, here's a great video about it. This made OSs shift from corporate-specific functions to general usage. Those later on had a big influence on GNU/Linux and MacOS, which we're going to review in a sec.īy the 1980's, computers performance, accessibility, size, and price had improved to a point where the general public could buy them and use them for personal tasks. Unix was hugely successful and inspired the creation of many other OSs with very similar characteristics. The most notorious of these projects was Unix, which was an OS developed in Bell labs at AT&T by developers Ken Thompson (who's currently working on the development of the Go programming language) and Dennis Ritchie (who also created the C programming language. It's amazing how low level things were at that time and the progress technology has achieved thanks to those early programmers.īy the 1960's industry giants such as IBM and AT&T started working on operating systems that could act as a layer of abstraction between hardware and software, which would simplify the implementation of new programs. It just blows my mind every time I think about it. Side comment: Do you ever stop and think about the work of a programmer back in those days? Programs were written in punch cards! =O There was no layer of abstraction between the running program and the actual hardware. If you wanted to execute the same program on a different computer model, programmers would need to write the whole program again because the hardware was configured in a different way. That means a program could run on one and only one computer model. In the old days (1940's-50's) programs were written to run on specific machines. Nowadays any given program can worry only about executing its core features and leave all basic system functionalities to the OS. OSs were created to simplify the use of computers. It will manage crucial basic tasks such as file management, memory management, process management, input-output management, and controlling peripheral devices. You can think about an OS as an "intermediary" program that stands between your computer and all other programs you run on it.
#HOW TO CODE UNIX ON MAC SOFTWARE#
"An operating system (OS) is software system that manages computer hardware, software resources, and provides common services for computer programs".

Hi everyone! In this handbook I'm going to give a brief introduction to operating systems and compare the three main OSs that are out there nowadays.įirst we're going to review what an OS is and little history about them.
