An operating system is the software responsible for managing all the resources of a computer, from data processing to user interaction. It is the basis for other programs to run on the computer.
There are several types of operating systems, each with its specific features and functionality. The best known are:
- Windows: developed by Microsoft, it is the most used operating system in the world. It is known for its user-friendly GUI and ease of use.
- MacOS: developed by Apple, it is exclusive to branded computers. It is known for its stability and distinctive design.
- Linux: is an open source operating system, that is, it can be modified and distributed freely. It is mainly used on servers and by advanced users.
In addition to these, there are other lesser-known operating systems, such as FreeBSD and Android (used on smartphones and tablets).
The operating systems are responsible for managing the computer's resources, such as memory, processor, input and output devices, among others. They are also responsible for allowing other programs to run on the computer.
An operating system is made up of several layers, each with its own specific function. The lowest layer is the kernel, which is responsible for managing the computer's hardware. Above that are drivers, which allow communication between the kernel and hardware devices.
