Understanding Computer Operating Systems

Buy nowOur body couldn’t function without our brains. The brain tells the various pieces of our body how to work and how to interact. Without a brain, we wouldn’t be able to do anything at all. An operating system is kind of like the brain of a computer. You have a bunch of hardware like the CPU tower, the monitor, and the keyboard, but without a CPU, they can’t do anything but power up and turn on. The operating system organizes files and lets the hardware know what it should do.
An operating system – commonly referred to as an OS – is a set of computer programs that manage the hardware and software resources of a computer. The OS processes electronic devices with a rational response to commands that are approved by the system.
At the foundation of all system software, an operating system performs basic tasks like controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating the network, and managing files. The OS can also provide a graphical user interface for higher functions. Essentially, the OS forms a platform for other system software as well as application software.
The operating system is the most important program that runs on a computer. Without an operating system, your computer would not work. It would not be able to process requests for print, simple calculations, or any other function. It is really the brain that runs the equipment.
For larger system, the OS has great responsibilities than with a PC. In larger systems, the operating system is kind of like a traffic cop. It makes sure that different users and programs running at the same time on different systems don’t interfere with each other. It also acts as a security guard making sure that unauthorized users are not able to access the system.
