How to calculate virtual memory in 80286 microprocessor?

In: Intel Microprocessors [Edit categories]

Answer:

Virtual memory does not exist physically but it is available in the system
The procedure of fetching the chosen pgm. Segments or data from the secondary storage into the physical memory is called swapping
So it can address 1GB

Physical address calculation in PVAM

It uses 16-bit content of a segment register as a selector to address a descriptor stored in physical memory
The descriptor is a block of contiguous memory locations containing information of a segment
Privilege levels prevent unauthorized accesses
Maximum segment size will be of 64kb
