Advantages and disadvantages of paging in operating system

Answer 1

Advantages of single user operating system:Supports one user at a time:-In these systems one user is only active at a time. So there will be no other user interfering with the applications. And in these systems all computer resources are used by a user requests.Easy to maintain:-These systems uses less resources and complexity of them is less so it is easy to maintain and debug. In multi user operating system there are higher resources needed and resources are in use most of time. Disadvantages of single user operating system:Tasks take longer time to complete:-As you know if no multiple tasks run at a time then many tasks are waiting for the CPU. This will make system slow and response time is higher. So these systems response to processes at higher time.Idle time is higher:-If only one task is running and this task don’t require memory or I/O use then these devices remain idle. But other tasks need thosedevices.So only one task run at a time then other tasks have to wait till first task is finished. So CPU, memory and disk I/O not used properly.
