Textbook Question
Chapter 6, Problem 6.24HW
Suppose that a 2 MB file consisting of 512-byte logical blocks is stored on a disk drive with the following characteristics:
| Parameter | Value |
| Rotational rate | 15,000 RPM |
| Seek | 4 ms |
| Average number of sectors/track | 1,000 |
| Surfaces | 8 |
| Sector size | 512 bytes |
For each case below, suppose that a program reads the logical blocks of the file sequentially, one after the other, and that the time to position the head over the first block is Tavg seek + Tavg rotation.
- A. Best case: Estimate the optimal time (in ms) required to read the file over all possible mappings of logical blocks to disk sectors.
- B. Random case: Estimate the time (in ms) required to read the file if blocks are mapped randomly to disk sectors.

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forward
