Final Exam CS 1313 HW

HOWMUCH will CodeLab cost?

$25 per student for the entire semester

1. WHY are floppy disks so expensive per MB, compared to CD-RWs and DVD-RWs?

(a) Because floppy disks are outdated, and no one is producing them because there are better mediums that are more efficient and cheaper to mass produce. Well, an individual BD-RE has much greater capacity than an individual floppy (25-100 GB versus 1.44 MB), and the costs of manufacturing the actual physical objects are similar. And, because floppies are much less popular than CDs, they aren't manufactured in high quantities - so it's harder to amortize the high fixed costs of running the factory. So, the cost of a floppy per MB is much higher.

NAME TWO EXAMPLES of optical secondary storage media, and give an advantage and a disadvantage of each.

(a) Blu-Ray • Advantage: it can be read from, and it can be addressed arbitrarily • Disadvantage: it cannot be written to (b) CD-RW • Advantage: it's nonvolatile • Disadvantage: much slower than ROM:

NAME TWO DIFFERENCES between main memory and cache.

(a) Cache is faster than main memory (RAM) (b) RAM is cheaper and bigger than cache

1. WHY do computers have cache storage?

(a) Cache is much faster than RAM, so the CPU doesn't have to wait nearly as long for stuff that's already in cache: it can do more operations per second!

NAME TWO EXAMPLES of magnetic secondary storage media and give an advantage and a disadvantage of each.

(a) Magnetic Tape • Advantage: It is one of the cheapest per MB secondary storage media type compared to others. • Disadvantage: It has a much lower latency compared to other media which makes it less efficient than other secondary storage media with a similar price range. (b) Cassette • Advantage: The secondary storage media can de written and it is portable. • Disadvantage: However, it is very outdated which means that it is very slow and does not have as much storage capacity as other media within a similar price range.

When data and instructions reside in the following kinds of storage, WHEN are they expected to be used?

(a) Registers: where data and instructions reside that are being used right now. (b) Cache: where data and instructions reside when they are going to be used very very soon or have just been used. (c) Main memory: where data and instructions reside when a program that is currently running is going to use them at some point during the run (whether soon or not). (d) Secondary storage: Where data and instructions reside that are going to be used in the future.

NAME TWO DIFFERENCES between magnetic media and optical media.

(a) Some optical media can be written only once, and some can be rewritten multiple times while magnetic media can always be written and rewritten multiple times. (b) Magnetic media can be erased by magnets while optic media cannot.

Which of the following is the correct way to calculate your overall percentage score for the semester?

Add together all your points for all assignments of all types, then add together all the maximum points for all assignments of all types, then divide the two sums?NO Add together all your points for all assignments of all types? NO For each assignment type (for example, quiz, programming project, CodeLab), do the following: For each assignment type, add up all your points for all assignments of that type. For each assignment type, add up all the maximum possible points for all assignments of that type. For each assignment type, divide the first sum by the second sum to get the fraction of points that you got for that assignment type.
