The operating system is the type of software that is responsible for managing the processor time and also the memory allocation in the system. The operating system mainldeals with the processor time by scheduling the processor work done in the system.
The OS mainly controls the system and then schedule the execution of various types of function by the central processing unit (CPU). It also controls the memory allocation in the system.
System restore is a recovery feature that helps restore your system to the previous condition or point. Most computers have system restore disks which are an advantage to the users especially when the computer clashes.These disks are very effective when it comes to restoring the system to its initial state.
If an OS is using paging with offsets needing 12 bits, give the offset (in decimal or hexadecimal) to: the third word on a page the last word on a page.
