Answer:
c) search operators
Explanation:
Words or symbols that help you narrow down your search are called search operators. This ultimately implies that, search operators are commands and special characters (words or symbols) which help users to filter and refine their search engine results by making the search more precise and specific in nature. Thus, search operators only provide search engine results that are relevant to what a user is searching for or it narrow down the focus of a search.
Hence, search operators comprises of commands and special characters (words or symbols) such as AND, OR, NOT, "", -, +, *, .., :, etc used for narrowing down search engine results.
For instance, typing "file.mp3" in a search engine would only present results that are in mp3 formats.

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.
Normalization is the odd option out as it is used to restructure data in other to promote integrity of data.
Answer:
Digital logic circuits made of cascaded flip flops.
The different types of Bit Shift Registers are; Serial-In Serial-Out, Parallel-In Parallel-Out, Serial-In Parallel-Out, Parallel-In Serial-Out.
Shift registers can be used as converters to translate data, as delay circuits or counters.
Explanation:
Shift Registers are digital logic circuits made of cascaded flip flops. Their main function is to shift their contents (bits) to the right or to the left one bit at a time. Bit Shift Registers can process data either parallelly or serially. So the different types of Bit Shift Registers are;
- Serial-In Serial-Out
- Parallel-In Parallel-Out
- Serial-In Parallel-Out
- Parallel-In Serial-Out
Because of their ability to convert data from parallel to serial, shift registers can be used as converters to translate data. Some of their other applications are also delay circuits or counters, storing and manipulating data etc.
I hope this answer helps.
