Virtual memory factors
Not enough HDD space allocated to extend RAM
(page file too small - the page file is a section of the hard disk that is reserved as an extension of the RAM).
Heavy use of virtual memory relies on slow disc transfers rather than the very fast working memory
(RAM)
data transfers.
Operating systems require careful maintenance to keep them performing efficiently.
The operating system is what coordinates all the operations of your computer.
It manages all the resources on the computer, such as the CPU and RAM, and controls the software and hardware.
Without it, your PC would be useless
.
Types of Operating Systems
Real-time operating systems
(RTOS)
Inputs are processed and responded to instantaneously.
Single-user single task operating systems
One user can use the system at a time, and one application can run at a time.
Single-user multitasking operating systems
One user can use the system at a time, but many applications can run simultaneously.
Multi-user operating systems
Many users can use the system at the same time and can run many applications simultaneously .
