It manages the amount of hardware being used especially when there are a number of uses trying to access the different components of hardware at the same interval of time. This means that it prevents the system from being overloaded or from a less load. The operating system acts as a Resource Manager. That means these points tell us the functions which are essentially done by the operating system: The following points describe the functionality of an operating system. Secondly, this operating system provides convenience to the uses and a throughput which makes it an essential component of the system. It reduces the work load of the user and makes the access to the hardware as easier task. This is the place where the operating system acts as the master. This is a difficult task for the user to keep devising the programs every single time they want to use the hardware. Hence, for every single command of a user, a separate program should be devised in order to make the hardware understand and make it perform the task given to it. Instead some program should be written in order to instruct the hardware about what is the next step to be done. In this situation, the user cannot give a direct demand of performing some action to the hardware. Let’s consider an example where there is no operating system and there is a direct contact between the user and the hardware. We all might think a common thing which is that “What makes the operating system so essential for a system to work”? The answer to this question is very simple. The hardware normally consists of the CPU (also known as the brain of the computer), the input/output devices (which consist of the keyboard, mouse, scanner, printers etc…), the RAM (the Random Access Memory which is also the main memory of the system) and the hard disk (which is known as the secondary memory of the system). This operating system acts as an INTERFACE between the user and the system’s hardware.
