Answer and Explanation:
POLLING MODE: In polling mode in communication process the processor continually check UART port for data instead of UART port signaling the process through an interrupt when data is ready as is done in interrupt mode.
THE DISADVANTAGES AS COMPARED TO THE INTERRUPT MODE :
the disadvantages in polling mode is that the processor wastes time in checking the UART continually while in interrupt mode it is doing useful task
until the UART interrupt this
Answer:
Increased processor speed and multi core technologies.
Explanation:
The development of processors over the years is overwhelmingly fast. The CPU use to be cumbersome, expensive and computational speed was moderate.
As it evolves, the CPU was minimized to give rise to microprocessors.
Microprocessors are very fast, running millions of processes on its core. The multiple core processors helped to increase the speed of these processors.
When there are more than one core in a processor (dual, quad or octal core), it processes data in parallel reducing the time of execution compared to a one core processor.
A company having computers with single core would need to upgrade to a new computer with multi core processor to promote speed in data processing.
The answer is C. The third choice.
Answer:
* The code is in Python
def joinStrings():
join = ""
while True:
str = input("Enter a word or Q to stop: ")
if str == "Q":
break
else:
join = join + " " + str
return join
print(joinStrings())
Explanation:
Create a function called joinStrings
Initialize join variable to hold the strings that will be combined
Create a while loop that stops when user enters "Q". Otherwise, ask the user for a new string and join it to the join variable with a space
When the loop is done, return the join
Call the function and print the result
Nominal data is qualitative data; non-numeric data; observations are organized into categories without any recognition of order.
<h3>What is
qualitative data?</h3>
Qualitative data is information that cannot be counted, measured or easily expressed using numbers.
It is collected from text, audio and images and shared through data visualization tools, such as word clouds, concept maps, graph databases, timelines and infographics.
Qualitative data is the descriptive and conceptual findings collected through questionnaires, interviews, or observation.
Analyzing qualitative data allows us to explore ideas and further explain quantitative results.
For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire.
