f I am running 100 applications on my computer with a 2-level page table, how much memory do I have to keep in RAM at all times to be able to access all applications’ data? Choose the correct answer. >400MB (need the full page table for each application) >4KB+4KB (need the 1st level page table and one 2nd level page table) >400KB (just need the 1st level page table for each application) >800KB (need the 1st and 2nd level page table for each application)

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
