On a computer with 32-bit addresses, suppose we have a 2 GB main memory, that is byte addressable, and a 512KB cache with 32 bytes per block.
What would be the format of the memory address for fully associative caching technique?
Answers
The format of the memory address for fully associative caching technique is option C: c) TAG= 13 SET = 14 WORD =5.
The definition of fully associative cacheA fully associative cache allows data to be stored in any cache block rather than forcing each memory address into a specific block. — Data can be stored in any vacant block of the cache when it is read from memory.
Note that the term "fully associative mapping" refers to a cache mapping technique that enables mapping of the main memory block to an openly accessible cache line.
Furthermore, data could be stored in any cache block with a fully associative cache. Every memory address wouldn't have to be confined to a specific block and option c best fit the statement above.

What is the difference between a while loop and a for loop?
Both the for loop and the while loop is used to execute the statements repeatedly while the program is running. The main distinction between the for loop and the while loop is that the for loop is used when the number of iterations is known, whereas the while loop executes until the statement in the program is proven incorrect.
Iteration refers to a single execution of the loop body. In the preceding example, the loop iterates three times.
If i++ were not present in the preceding example, the loop would (in theory) continue indefinitely. In practice, the browser provides methods to stop such loops, and we can kill the process in server-side JavaScript.
Any expression or variable, not just comparisons, can be used as a loop condition: while evaluating the condition and converting it to a boolean.
