Read the following and answer the questions : Consider a machine with 16 GB main memory and 32‐bits virtual address space, with page size as 4KB. Frame size and page size is same for the given machine.
Find number of pages required for the given virtual address space
2 20
The virtual space contains \(2^{32}\) bytes and each page contains \(2^{12}\) bytes. Hence the number of pages is \(\frac{2^{32}}{2^{12}}=2^{20}\).
Important Questions from Frame Allocation - Teaching
If a process of size 34KB is to be executed on this machine, then what will be the size of internal fragmentation for this process?
- The number of bits reserved for the frame offset is ______
For the machine described in the passage, assume byte addressing and a single-level page table containing one 4-byte entry for every virtual page in the complete 32-bit virtual address space. Each entry includes the physical frame number and control bits. What is the page-table storage size, excluding any additional overhead?
Use binary units: 1 KB = \(2^{10}\) bytes, 1 MB = \(2^{20}\) bytes, and 1 GB = \(2^{30}\) bytes.
