How do you find a Block in a Cache? Tag is recorded by each place in the cache along with its data. The place in the cache might be unoccupied, so it usually maintains a valid bit. A specific position within a cache line is identified by an offset part. All of Above O The set that has the requested data is identified by a set part.

A good stack canary keeps an eye on both the memory that it produces and the memory that it uses.What prevents the intruder from reading the canary value and then inserting it into the payload overflow during a standard buffer overflow attack (e.g., using the gets() function)?
The following blocks are referenced by the CPU and to be fetched from the RAM to the cache sequentially: (i j k L L j m j n L m j m L k S j P i O k) Assume that the cache set is empty and all the above blocks can be inserted into the set. Use the LRU algorithm to fill in the following table that describes the status of the cache locations for each called block. Note : All numbers must be binary
Operating sys :In the following producer and consumer problem using semaphores, explain with an example (semaphore values), how a producer sends a signal to a consumer, so that the consumer does not have to check the buffer all the time. /*program, Producer/Consumer */ semaphore n = 0; /* no of items in the buffer */ semaphore s = 1; /* ME semaphore */ void Producer () { while(TRUE) { produce(); wait(s); append(); signal(s); signal(n); } } void Consumer () { while(TRUE) { wait(n); wait(s); take(); signal(s); consume(); } }

Which of the following statements best describes this code that is attempting to print the value of a disk block. Note that syntax of queue has changed slightly from the assignment to simplify it. void interrupt_service_routine(){ int* result; void (*callback) (int*); queue_dequeue(&result, &callback); callback(result); void printInt(int* i){ printf("%d\n", *i); free(i); void read (int blockno){ malloc(sizeof(int)); queue_enqueue(result, printInt); disk_read(result, blockno); int* result It has an error : it might print before the read has completed. X O It makes incorrect use of function pointers. O It has a dangling pointer bug. OIt has an error: it never calls interrupt_service_routine. It has a memory leak bug. OIt is correct. X 0%
A message slot is a cache line that contains status flags and the message itself. The state can be empty or ready, and communication occurs through a single cache line. Both the sender and the receiver write the message to the cache line. The receiver updates the state from empty to ready, then polls the cache line in a loop waiting for the sender to send a message. The sender waits in a tight loop until the receiver acknowledges the cache line, changes the state from ready to empty, and acknowledges receipt. Explain that the system uses a snooping cache coherence protocol and describe the cache-coherence transaction taking place on the coherence bus when a message transfer occurs.

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.
