Answer:
Normalization
Explanation:
From the options given :
Boxplot is a data visualization techniqye used for representing numerical data in the form of a box such that it adequately conveys the five number summary if the dataset which are the minimum, maximum, lower quartile, median and upper quartile, it also depicts the presence of outlines.
Scatter plot are used depict the relationship between two variables on the x and y axis of a graph. Each point is a representation of the (x, y) value pairs of the observation.
Tag clouds are usually used to represent word, metatdata and other free form text using different colors and font sizes to give information about the data.

Answer:
TRUE
Explanation:
In telecommunication and computing, there are different units of data storage. The most commonly used units are the bit and the byte.
A bit is the capacity of the system having only two states.
Whereas, the byte, also known as octet, is equal to eight bits. The unit symbol for Byte is B. In many computers, it is the smallest addressable unit of memory.
Therefore, <u>the given statement is TRUE</u>.
Answer:
a. 100%
b. 50%
c. 66.6%
Explanation:
a.
The memory references D6, 58, D8, 9A, DE and 5C all results in misses and the miss ratio is 100 (that is , 6 misses/ 6 references*100 = 100%)
b.
If fully associative cache is used, there will be a 3 cache misses with miss ratio of (3/6*100) = 50%.
c.
With a 2-way set-associative cache, 4 memory reference misses will occur, with a miss ratio of (4/6*100)= 66.6% misses.
A device, usually external to a computer that is plugged into a computer's communication port or is connected wirelessly. Common peripherals are keyboards, mice, monitors, speakers, and printers
