Operating Systems

Operating Systems

1. Multitasking

   • By giving the processor a small time slice for each task means that all tasks to be executing at the same time.

2. The user interface

   • the user interface provides a means of communication between the user and the operating system.The user-interface layer is above the kernel so one operating system kernel can provide a range of user interface.

3. Memory management

   • The OS allocates memory between the different programs that are open at the same time.programmers and users do not need to know where in memory data is being held it is the purpose of the operating system to do this

4. Drives

   • A piece of software used to control a piece of hardware.Drivers allow a peripheral device to be connected to a computer and it is
     • used by an operating system.

5. Peripherals management

   • Operating systems manage the way in which hardware interacts with software.A peripheral is a piece of hardware that is not directly conenected to the CPU-such as a keyboard a mouse or even a hard disk drive

6. File management

   • like memory management the operating system must identify where files are stored for long term storage on for e.g. the hard disk drive or a solid state drive.
