Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records. If a2 has the address of a student record, if using indexed addressing mode, what is the index value X such that X(a2) addresses the course mark?

The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records. If a2 has the address of a student record, what is the location of the next record in the array / data area:
What memory blocks will be in the cache after the last address has been accessed?
ALSO: What is the hit ratio for the memory accesses (Round to the nearest percent.)
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.

Assignment/Lab 9 In this lab, your task is to develop a simple address book tool. The tool maintains contact information of people. For each person, the tool maintains name and date of birth. Contact information consists of physical address and phone number. For physical addresses, the system must be able to maintain current and previous addresses. Current/active address information should have starting date and no end date, previous addresses must have a starting date and an ending date. A person cannot have multiple active physical address. For phone number, the system must maintain active phone numbers only, no previous phone numbers. For implementation, use MySQL database system. MySQL is open source and is available for Linux as well as Windows. For software application, use Python. The tool/application must support the following functionality: 1- Search current contact information by last name, the user enters last name, the system must locate active physical address and phone…
Answer this question please.
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. a) Suppose that the OS uses a two-level page table. Draw the page table. (Assume that frames 7 through 221 are free, so you can allocate space for the page table there.) In addition, suppose that the page-table directory storage comprises a whole number of consecutive full frames. (For examples: if the directory entry is 2 bytes, the entry’s storage comprises 1 frame; if the directory entry is 260 bytes, the entry’s storage comprises 2 consecutive frames.) b) What is the size of the two-level page table c) Now, translate the virtual addresses shown in question I(e) to physical addresses for the two-level page table. Show how you obtain your answers. 0x0389 0xDF78 0x0245 0x8012
1. Suppose an array with six rows and eight columns is stored in a row major order starting at address 20 (base 10). If each entry in the array requires only one memory cell, what is the address on the entry in the third row and fourth columns? What if each entry requires two memory cells?
Select problem below. Your post must include: The problem statement. A description of your solution highlighting the use of the split(), join(), lists and the different list operations involved in solving the problems. Include line numbers from your program. please make it simple and DONT use Java Create a program and reads a MAC address and determines whether it is syntactically correct or not. Assume the format of the MAC address is dd-dd-dd-dd-dd-dd where dd represents a 2-character hexadecimal number (each character is a digit or a letter between a and f). Use the `split function to access the values in the input MAC address.
cache.xls (or it can be a google sheet that you share with me in a cache.txt with the url in it )= a spreadsheet showing the cycle counts of a cached and non-cached machine. Also, you need to show the cache as the memory accesses progress in your program marking the hits and misses (misses in RED). You should have cells to show how many hits and how many misses your program has, and details on what is the cache replacement policy you implemented. Here is code: void c_cache_for_badge() { int na = 8, nb = -3, nc = 10; // pointers int *npa; npa = (int*)malloc(sizeof(int)*84); // init integer pointers for(int i = 0; i < 84; i++) { npa[i] = i; } // integer pointers for(int i = 9; i < 70; i= i + 3) { nb += npa[i % 5] + npa[i % 3] + npa[i % 6]; } } void main() { c_cache_for_badge(); }
