That can include processing power, memory allocation and computer storage access, among other things. As you run applications on your computer, the OS allocates the resources necessary to complete the task.

It's the job of the OS to monitor what software needs and what the hardware can provide. Operating systems are like the manager for a computer. To do the same with hardware would mean switching out physical chips and circuit boards. Software is more malleable than hardware - you can make changes through software patches and version updates.

That's why operating systems like Mac OS X and Windows are software. But such an operating system would be inflexible. This would require building electrical pathways using millions of logic gates. You could design an operating system by physically programming it into a computer's circuits. Only the hardware's physical properties and our own imaginations can limit what programs can do. The operating system allows complex programs to access the capabilities of the hardware to get results.
But personal computers need to be more versatile. Some simple computers have no need of an operating system because they only perform a specific task. We define these rules using things like logic gates, which take input and produce an output in a predictable way. The hardware behaves according to strict rules.
It takes input in the form of zeros and ones - bits - and channels them through various circuits and processors. Without it, your computer would just be a paperweight.Īt its heart, a computer is a number-crunching device. The OS acts as a platform for all other applications on your machine. The operating system interacts with a computer's hardware on a basic level, transmitting your commands into language the hardware can interpret. What's the big deal about operating systems in the first place? What do they actually do? An operating system is the level of programming that lets you do things with your computer.
