An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.

Time-sharing #operating_systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

Operating system Full Course: https://youtu.be/mXw9ruZaxzQ

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

The modern periodic table is based on the periodic law: "The chemical properties of elements are a periodic function of their atomic number." Let's see how is this different from Mendeleev's periodic table and how this solves for its predecessor's limitations.

Country is not just a fad of “singing cowboys”. Country has affirmed its name over time, it's a solid foothold, distinctive colors and loyal fan base of all ages.

Despite all the time mixing with other genres, the flickering guitar sound, the rattling sound of the banjo combined with the fiddle and harmonica has always remained a very solid spiritual representation of the "Western" culture. America" - a genre of music that comes from the United States, but not only America but also a culture that is admired by the whole world.
