- Suppose we have a computer system with 44-bit logical addresses, page size of 64KiB, and 4 bytes per page table entry. b. Suppose we use two-level paging and arrange for all page tables to fit into a single page frame. How will the bits of the address be divided up? (show your work) c. Suppose we have a program with a 4GiB address space. Counting the program and all page tables, using the two-level page table scheme from the previous question, how much memory, in number of page frames, is used?

Show all the possible floating-point numbers that can be represented in this 9-bit system. You need to compute all the floating point values that can be represented. Please post it here for a copy and paste.Consider finding a prefix code for a file that consists of the letters a, b, c, d, and e. Suppose that these letters appear in the file with the following frequencies. f(a) = 20; f(b) = 7; f(c) = 10; f(d) = 4 and f(e) = 18: Suppose each character was represented by four binary digits before compression. What is the total number of bits utilized by the data before compression? Apply the Huffman Encoding technique to compress the data and find the total number of bit required to represent the complete file after compression. What is percentage of space saved by the compression technique?Suppose the Vole communicates with a printer using the technique of memory-mapped I/O. Suppose also thataddress 0xFF is used to send characters to the printer, and address 0xFE is used to receive information about theprinter’s status. In particular, suppose the least significant bit at the address 0xFE indicates whether the printeris ready to receive another character (with a 0 indicating “not ready” and a 1 indicating “ready”). Starting ataddress 0x00, write a machine language routine that waits until the printer is ready for another character and thensends the character represented by the bit pattern in register 0x5 to the printer.
