A computer system has 6 page frames. The table below shows the time of loading, thetime of last access, and the R and M bits for each page (the times are in clock ticks).Frame Loaded Last accessRM018031010125275112153001131902251041202150159020001The system has to load two new pages into RAM, so it has to remove two of those pagesthat are already loaded. For each of the algorithms below, determine which two pages aregoing to be replaced:(a) not recently used (NRU);(b) least recently used (LRU);(c) first-in, first-out (FIFO);(d) second chance.All answers should be justified!

Task #2 - Write a MIPS program where you prompt the user for an integer a. Then, set bit 9 and 20. Finally, display the value of that integer after modification. Sample Run of the task Sample Run of the task Enter a: 96 Result = 1049184 Enter a: 4112 Result = 1053200
File sizes are measured in bytes (8 bits). A 24 megapixel camera's recording chip might have a 4000 X 6000 grid of pixels-- that's 24 million pixels. if each uses 8 bits for each color, (red gren blue), each image will produce a 72 megabytes file. Q:
3. Draw the memory map for 8 bytes starting at 0x2000_0030 as shown in the form given above.
As the error-detection and correction capability of a code increases, we would expect in general the overhead bits to protect a group of data bits to decrease remain the same increase
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…
A certain moving arm disk storage, with one head, has the following specifications. Number of tracks/recording surface = 200 Disk rotation speed = 2400 rpm Track storage capacity = 62,500 bits The average latency of this device is P msec and the data transfer rate is Q bits/sec. Write the value of P and Q.
Student information is stored in a data area, and each student entry is formatted as follows:The first nine bytes are the student ID in ASCII format.The following byte is the course score.The following phrase is the section identifier. There are over 300 such student records in memory, which have been loaded consecutively beginning at address $10000. To indicate the conclusion of the records, the last record loaded is a dummy record with a section identifier of $FFFF. Create an assembler subroutine GetMax that searches the complete list for the highest mark. If there is a tie, the student with the highest score on the list should be found. The beginning address of the subroutine should be returned.
A certain disk can read data at a rate of 515.2 MB/s. How many books can be read in 4 seconds if an "average" book has69 pages,20 lines per page,9 words per line,6 characters per word,and each character is one of 100 different characters where the fewest number of bits are used to represent each character?
It is common practise to divide computer memory into many categories using bytes, each of which consists of 8 bits. How many dist values can a tell? How many distinct valueytes may be represented by two separate bytes?
