I have a global variable that I want to change and save in a function (in python). I have an if statement contained in a while loop where the code will pass the if and go to the elif part first, and runs the code with certain numbers, and changes some of them. Because of the changed numbers when the while loop runs again it should enter the if part, but it doesn't It uses the old values as if the function has not been run. FYI I am returning the values at the end of the function, it still doesn't work

Answers

From the above scenario, It appears that you could be facing a problem with the scope of your global variable. So It is essential to declare a global variable within a function before modifying it, to avoid creating a new local variable.

Why does the code  not work?

For instance, by using the global keyword within a function, such as my_function(), Python will know that the aim is to change the my_global_variable variable defined outside the function's boundary.

Therefore, When the my_function() is invoked in the while loop, it alters the global variable that is subsequently assessed in the if statement.

A hard disk drive has 10 surfaces, 10240 tracks per surface, and 512 sectors per track. Sector size is 4 KB. The drive head traverses 1280 track/ms and the spindle spins at 5400 r.p.m.
(a) What is the total capacity of hard disk drive (in GB)?
(b) What is the physical address of the sector whose logical block address (LBA) is 2312349 ?
(c) What is the longest time needed to read an arbitrary sector located anywhere on the disk?

Answers

(a) The total capacity of the hard disk drive is 10 surfaces * 10240 tracks/surface * 512 sectors/track * 4 KB/sector = 204800 MB = 200 GB.

What is the physical address of the sector?

(b) The physical address of the sector with LBA 2312349 is calculated as: surface = LBA/(trackssectors) = 2312349/(10240512) = 4; track = (LBA%(trackssectors))/sectors = (2312349%(10240512))/512 = 2512; sector = LBA%sectors = 2312349%512 = 85.

So, it's (4, 2512, 85).

(c) The longest time to read an arbitrary sector is from the outermost track to the innermost track (10240 tracks) at 1280 track/ms speed, plus one full rotation at 5400 RPM: (10240/1280) ms + (60/5400) s = 8 ms + 11.11 ms = 19.11 ms.

AMAT This is within .01 cycles of the correct answer which is 48.83 cycles.

What is Average Memory Access Time?

Average Memory Access Time (AMAT) is the amount of time it takes for a computer's processor to access data from memory. It is measured in nanoseconds and is typically much shorter than the time it takes to access data from a hard drive. The speed of memory access is critical to the performance of a computer, as it is one of the main factors in determining the overall speed of the computer and its ability to run programs. Memory access time is affected by the type of memory used, the speed of the memory, and the amount of memory available. Faster memory and larger amounts of memory will generally result in lower AMAT.

Average Memory Access Time = (L1 Hit Time x L1 Hit Rate) + (L2 Hit Time x (1-L1 Hit Rate) x L2 Hit Rate) + (L3 Hit Time x (1-L1 Hit Rate) x (1-L2 Hit Rate) x L3 Hit Rate) + (DRAM Access Time x (1-L1 Hit Rate) x (1-L2 Hit Rate) x (1-L3 Hit Rate))
Average Memory Access Time = (1 x 0.97) + (9 x (1-0.97) x 0.83) + (33 x (1-0.97) x (1-0.83) x 0.63) + (190 x (1-0.97) x (1-0.83) x (1-0.63))
Average Memory Access Time = 0.97 + 6.96 + 8.50 + 32.39
