A hard disk has 32 sectors/ track, 10 platters each with 2 recording surface and 1000 cylinders. The address of a sector is given as where c is cylinder no., h is for surface no., s is for sector no. Thus the 0th sector is addressed as <0, 0, 0>, 1st sector as <0, 0, 1> and so on. Then the address <200, 8, 20> corresponds to which sector no.?

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

A hard disk has 32 sectors/ track, 10 platters
each with 2 recording surface and 1000
cylinders. The address of a sector is given as <c,
h, s> where c is cylinder no., h is for surface no.,
s is for sector no. Thus the 0th sector is
addressed as <0, 0, 0>, 1st sector as <0, 0, 1>
and so on.
Then the address <200, 8, 20> corresponds to
which sector no.?

There is an application that requires the following hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables and a Data RAMs of 8Kx8. The memory map of the design: Program ROM should start at address 0000H. Then, the Data ROM should come above the Program ROM. Finally the Data RAM must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs. Show the design’s address space on a memory map, starting with 0000H at the bottom and FFFFH at the top.
Consider the following table that represents part of the memory of a 16-bit address space that has an addressability of 2 bytes (like LC-3): ADDRESS OxFFFF OXOCOE OXOCOD Ox0C0C OXOCOB OXOCOA 0x0C09 0x0000 CONTENTS 1111 1111 1111 1111 1111 1110 1101 1100 0001 1011 1100 0101 0110 0101 1000 0111 1100 0000 0100 0000 0011 0001 0101 0010 0000 1100 0000 1101 0000 0000 0000 0000 The table above shows the addresses in hex (base 16) and the contents at the corresponding address in binary (base 2).

A computer manufacturing company is involved in memory design. They need to develop a proper plan before entering into the production part. The objective is to design a memory based on five partitions of varied sizes. The sizes are as mentioned below: 100 KB, 300Kb, 500KB and 600 KB. With these varied partition sizes available, the allocation should be made to four processes of sizes 112KB, 212KB, 426 KB and 462 KB. The three available allocation algorithms called First Fit, Best Fit and Worst Fit, perform the allocation of the processes
Computer Science Write an 8051 assembly language program to determine if a sequence of bytes is a palendrome. The number of bytes in the sequence will be stored in memory location 0x20 and the sequence starting at location 0x21. For example MOV 0x20 #0x05 MOV 0x21 #0x00 MOV 0x21 #0x10 MOV 0x21 #0x20 MOV 0x21 #0x10 MOV 0x21 #0x00 could be used to set up the data. Upon completion register R0 should contain a value of 0x01 if the sequence is a palendrome and 0x00 if it is not. Make sure you test your code on various input sequences (length 0, length 1, even length palendrome, even length non-palendrome, odd length palendrome, odd length non-palendrome.

Suppose a computer system uses 16-bit addresses for both its virtual and physical addresses. In addition, assume each page (and frame) has size 256 bytes. How many bits are used for the page number? How many bits are used for the offset? 8 bits each. With this system, what’s the maximum number of pages that a process can have? 256 Suppose that each entry in the page table comprises 4 bytes (including the frame number, the valid bit, and miscellaneous “bookkeeping bits”). An OS uses an array to store the page table. What is the size of the page table? 1024 Bytes Furthermore, suppose the first 6 pages of a process map to frames 222 to 227 (as decimal numbers), and the last 5 pages of the process map to frames 1 to 5 (also decimal numbers). All other pages are invalid. Draw the page table, including the valid bit and the frame number. DONE Translate the following virtual addresses to physical addresses, and show how you obtain the answers. (Hint: You do not need to convert…
Recently, a computer system was designed by Adam. He considered a paging system assured with a page table stored up in the memory. It was observed that when he used the associative registers, the references made to page tables were around 80 percent. During the whole process, the memory reference taken was about 150 ns. Adam was not sure what was the time taken for paged memory reference. Your task is to help Adam to compute the time for paged memory reference and the time taken for effective memory reference.
There are many parameters that could be used to describe disk performance; among them are: number of bits per track disk capacity (in bits) number of disk surfaces rotational speed rotational latency transfer rate tracks per surface sectors per track blocks per track sectors per block seek time speed of disk arm block-read time number of blocks Some of these parameters are independent, and others are (approximately) linearly related. That is, doubling one doubles the other. Decide which of these parameters are linearly related. Then, select from the list below, the relationship that is true, to within a close approximation. Note: none of the statements may be true exactly, but one will always be much closer to the truth than the other three. Also note: you should assume all dimensions and parameters of the disk are unchanged except for the ones mentioned. a) If you divide tracks into half as many blocks, then you double the read time for a block.…

Problem DescriptionThe Tower of Hanoi ProblemTower of Hanoi is a mathematical game consisting of three pegs (P1, P2 and P3) and a stack of disks of different diameters. Disks can slide onto any peg. The game starts with all disks stacked on P1 and ends at the point where all disks stacked on P3. The game player is required to move all disks from P1 to P3 using P2 as a buffer. Three rules must be followed when playing the game(1) Only one disk may be moved at a time.(2) Each move involves taking a disk on the top of a peg and place it on the top of another peg. (3) A disk of a larger diameter should never be placed on top of a disk of a smaller diameter. The diagrams below demonstrate the starting state and goal state of the game with 5 disks.Starting state Goal stateP1 P2 P3 P1 P2 P32RequirementsIn this assignment, students are required to solve the Tower of Hanoi (with five disks) using state space search algorithms implemented in Python.Two state space search algorithms: (1) a blind…
