Assume that a disk has 256 tracks, with each track having 64 sectors and each sector is of size 4M. The cluster size in this system can be assumed to be 4 sectors. A file having the name MCS012.txt is of size 128 M. Assume that disk has 16 free - continuous clusters of 8sectors each. How can this file be allotted space on the disk? Also show the content of FAT after the space allocation to this file. You may make suitable assumptions.


A computer has 4 GB RAM with each memory word of 64 bits. It has cache memory having
1024 blocks having a size of 128 bits (2 memory words). Show how the main memory
address (C1AAF0AB)h will be mapped to cache address, if
(i) Direct cache mapping is used
(ii) Associative cache mapping is used
8
(iii)Two way set associative cache mapping is used.
You should show the size of tag, index, main memory block address and offset in your
answer
Represent (-57.125)10 and (0.00000025)10 in IEEE 754 single precision and double precision
formats.
Assume that a source data value 1001 was received at a destination as 1101. Show how
Hamming's Error-Correcting code bits will be appended to source data, so this error of one
bit is identified and corrected at the destination. You may assume that error while
transmission occurs only in the source data and not the code.
Simplify the following function using K-map: F(A, B, C, D) = Σ (2, 4, 6, 7, 10, 14)
Draw the circuit for the function using NAND gates

Write a program that use the concept of jumping to perform one operation either ‘+’,

‘-’, ‘*’ or ‘/’ on any two user defined variable. Make separate function for each operation.

Use proper string messages to make your program readable.


Why microprocessor uses the binary number system and not the decimal or any other number system? How microprocessors deal with text, computer program, images, audio and video type of data using only binary number systems?
Make the sorting algorithm a separate .s file (subroutine).
Include the subroutine in the main file (i.e. Final2.s) and call (instruction BL) the subroutine to perform sorting, passing the argument (memory location of the data) through the stack (register SP).
Load the data into memory from the file list2.csv starting at 0x1000.
After sorting, take a screenshot of sorted results to prove your subroutine works correctly.
