Consider a user program of logical address of size 6 pages and page size is 4 bytes. The physical address contains 300 frames. The user program consists of 22 instructions a, b, c,... u, v. Each instruction takes 1 byte. Assume at that time the free frames are 7, 26, 52, 20, 55, 6, 18, 21, 70, and 90. 1. Draw the logical and physical maps and page tables 2. Allocate each page in the corresponding frame 3. Find the physical addresses for the instructions m, d, v, r 4. Calculate the fragmentation if exist
