3. The Kernel
The kernel has the task of:
- Loading / Unloading applications from memory
- Scheduling tasks to run efficiently on the CPU
- Memory management
- File storage to and from secondary storage devices such as the hard disk
- File management
- Data security
As we have already mentioned, there are many different types of operating system. The kernel within each type of operating system might be responsible for a slightly different blend of tasks.
For example, a 'single user, single application' operating system does not have to deal with networking, whereas the kernel in a network operating system would have to.
On the other hand, a device such as a mobile phone will have to have an extremely efficient memory management kernel as memory is a very limited resource.
