Long description

The figure shows the mapping of two blocks having sixteen and eight rows respectively.

Block 1: The virtual address space of the rows ranges from 0 K to 64 K in increments of 4 units. The rows labeled virtual page for each address space are labeled from bottom to top as follows. For 0 to 4 K, 2. For 4 K to 8 k, 1. For 8 K to 12 k, 6. For 12 K to 16 k, 0. For 16 k to 20 k, 4. For 20 k to 24 k, 3. For 24 k to 28 k, X. For 28 k to 32 k, X. For 32 k to 36 k, X. For 36 k to 40 k, 5. For 40 k to 44 k, X. For 44 k to 48 k, 7. For 48 k to 52 k, X. For 52 k to 56 k, X. For 56 k to 60 k, X. For 60 k to 64 k, X.

Block 2: The physical memory space of the eight blank rows from bottom to top are labeled from 0 to 4 k, upto 28 k to 32 k. The blank rows are labeled page frame. The rows of the two blocks are mapped as follows. Row 1 of block one is mapped to row 3 of block two. Row 2 of block one is mapped to row 2 of block two. Row 3 of block one is mapped to row 7 of block two. Row 4 of block one is mapped to row 1 of block two. Row 5 of block one is mapped to row 5 of block two. Row 6 of block one is mapped to row 4 of block two. Row 10 of block one is mapped to row 6 of block two. Row 12 of block one is mapped to row 8 of block two.
