We discussed one type of cache system, a direct-mapped cache of words (DMCW), to which cache line would the word at the main memory address 0x16C map, i.e., what is the cache index? Fill in the blank with your answer, expressed as a decimal integer.
Continuing the previous question, what would be the tag bits for the word at 0x16C when it is mapped into the cache? Fill in the blank with your answer as a binary integer in the format bbb...b, e.g., where b indicates a bit and the ... part indicates the presence of zero or more bits, e.g., 110100110.
Answers
The word at main memory address 0x16C would map to cache line 0. The cache index and the tag bits for the word at the main memory address 0x16C in a direct-mapped cache of words (DMCW).
In a direct-mapped cache of words (DMCW), each word in main memory can only map to one specific cache line. The mapping is determined by taking the least significant bits of the main memory address (in this case, the last two bits), and using them as the cache index. Since 0x16C has a binary representation of 101101100, the last two bits are 00, which means it would map to cache line 0.
The tag bits are the remaining bits of the main memory address after the cache index bits have been removed. In a DMCW, the size of each cache line is equal to the size of a word in main memory. Since we are dealing with a 32-bit system, each word is 4 bytes, or 32 bits. Therefore, the total number of bits in a cache line is also 32. The cache index takes up the least significant bits, which leaves the remaining bits as the tag bits. In this case, the tag bits would be 10110, which is the first five bits of the main memory address 0x16C.

A circle surrounding the earth at the equator would consist of ___________ “degrees” of angular measurement.
90
Answers
Answer:
360°
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the Sun. Therefore, in a 24 hour period, the earth rotates 360 degrees about its axis and as such in an hour it rotates 15 degrees to create a 24-hours time zones.
When the earth's equatorial plane intersect with the surface of a celestial sphere, it results in the formation of a great circle which divides or cuts the earth into two equal halves known as celestial equator. This great circle divides the earth into a circumference having two (2) equal halves.
Hence, a circle surrounding the earth at the equator would consist of 360 “degrees” of angular measurement. Thus, giving rise to latitude (zones of latitude) which is north or south of the equator that includes equatorial, low latitude, mid latitude, tropical, subtropical and polar regions.

What would be the output of the following statements? char* value="hello"; printf("%c", value); Oh hello O value Hello O None of the above
Answers
The output of the following statements is None of the above. This is because the `printf()` statement has `%c` which is used to print a single character. However, `value` is a character pointer and not a character.
Therefore, the output is undefined and will depend on the compiler used and the content of the memory location pointed to by `value`.To print a string using `printf()`, we use the `%s` format specifier. Therefore, the corrected statement to print the string stored in `value` is `printf("%s", value);`. This will output "hello" without quotes.Note: If `%s` was used instead of `%c`, then the output would have been "hello".

What connection exists between literals and variables?Literals are unprocessed data or values that are kept in a constant or variable. Variables can have their values updated and modified since they are changeable. Because constants are immutable, their values can never be updated or changed. Depending on the type of literal employed, literals can be changed or remain unchanged.

You have a single level cache system with the following setup
CPU -- Cache -- Memory The system has the following properties Cache Access Time 278ns
Cache Hit Rate 62%
Memory Access Time 3,797ns What is the average memory access time? Report your answer to TWO decimal places.
Answers
To calculate the average memory access time, we will use the formula and after applying the formula the memory access time comes as 1,720.86.
Average Memory Access Time = (Cache Hit Rate * Cache Access Time) + (Cache Miss Rate * (Cache Access Time + Memory Access Time))
First, we need to calculate the Cache Miss Rate: Cache Miss Rate = 1 - Cache Hit Rate = 1 - 0.62 = 0.38 Now, we can plug in the given values into the formula: Average Memory Access Time = (0.62 * 278ns) + (0.38 * (278ns + 3,797ns)) Average Memory Access Time = (172.36ns) + (0.38 * 4,075ns) ≈ 172.36ns + 1,548.50ns Average Memory Access Time ≈ 1,720.86ns So, the average memory access time for the single level cache system is approximately 1,720.86 nanoseconds to TWO decimal places.

However, if adding 5 points to a student’s original grade causes the grade to exceed 100 points, the student will receive the maximum possible score of 100 points. The students’ original grades are stored in the list gradelist, which is indexed from 1 to n.

The code segments that can so that the program works as intended is option a)gradeList [i] ← min (gradeList[i] + 5, 100) and option b)gradeList [i] ← gradeList[i] + 5
IF (gradeList [i] > 100)
{
gradeList [i] ← 100
}
Why are the statement correct?Since min (gradeList[i] + 5, 100) returns the minimum of the two expressions, it returns gradeList[i] + 5 if this is less than 100 and 100 otherwise. The software will therefore increase each grade 5 point with this code if it does not result in a result greater than 100, and set it to 100 otherwise.
This code will first boost the value of each grade by 5 before verifying if the updated grade is more than 100 using an IF statement. If so, the IF block's code will execute, setting the grade's value to 100.
As a result, using this code, the program will increase each grade 5 point total if it does not result in a result greater than 100 and reset it to 100 in all other cases.
