The exercise is about filling in the gaps and is related to the History of the ARPANET.
What is the History of the ARPANET?From the text:
In 1972, earlier designers built the ARPANET connecting major universities. They broke communication into smaller chunks, or packets and sent them on a first-come, first-serve basis. The limit to the number of bytes of data that can be moved is called line capacity, or bandwidth.
When a network is met its capacity the user experiences unwanted pauses. When the network is "slowing down", what is happening is users are waiting for their packet to leave the queue.
To make the queues smaller, developers created mixed packets to move simultaneously.

Why do Linux administrators prefer to give sudo access to application teams instead of letting them su to root?
Answer:
Explanation:
some distros like ubuntu do not even allow su to switch to root. furthermore the su to root is dangerous because the user becomes the all-powerful administrative account, so no warnings are issued if the application team user tries to do something system-breaking.

s to write a Python-program that uses training data to choose the four ideal functions which are the
best fit out of the fifty provided (C) *.
i) Afterwards, the program must use the test data provided (B) to determine for each and every x-ypair of values whether or not they can be assigned to the four chosen ideal functions**; if so, the
program also needs to execute the mapping and save it together with the deviation at hand
ii) All data must be visualized logically
iii) Where possible, create/ compile suitable unit-test
* The criterion for choosing the ideal functions for the training function is how they minimize the sum of all ydeviations squared (Least-Square)
** The criterion for mapping the individual test case to the four ideal functions is that the existing maximum
deviation of the calculated regression does not exceed the largest deviation between training dataset (A) and
the ideal function (C) chosen for it by more than factor sqrt(2
Use the knowledge in computational language in python is possible write the data about a function and the summation.
How to define function in Python?In Python, a function is a sequence of commands that performs some task and that has a name. Its main purpose is to help us organize programs into chunks that correspond to how we envision a solution to the problem.
So in an easier way we have that the code is:

return a + b
class Summation(object):
def sum(self, a, b):
self.contents = a + b

Explanation:
A processor accesses main memory with an average access time of T2. A smaller cache memory is interposed between the processor and main memory. The cache has a significantly faster access time of T1
For any single memory access, the theoretical speedup to access a word stored in the cache rather than in main memory is given by:
[tex]Speedup=\frac{T_2}{T_1}[/tex]
Given the following data:
Access time = [tex]T_1 < T_2[/tex]
What is cache?Cache can be defined as a random access memory (RAM) that is used by the central processing unit (CPU) of a computer system to minimize (reduce) the average time taken to access memory (AMAT).
For any single memory access, the theoretical speedup that would be used by the processor to access a word stored in the cache rather than in main memory is given by:
[tex]Speedup=\frac{T_2}{T_1}[/tex]
Where:
[tex]T_2[/tex] is the time to access in main memory.[tex]T_1[/tex] is the time to access in cache.Read more on processor here: https://brainly.com/question/5430107

Ask user to enter the maximum number of racers allowed for the race
Use repetition structure (loop) to ask the user to enter race times (in minutes)
Exit the loop if the user specifies there are no more times to enter (sentinel value) or if the maximum number of racers allowed has been reached
At a minimum, within the loop, you should keep track of how many race times are entered, the fastest race time and the slowest race time.
After the loop is exited, display how many race times were entered, the fastest race time, the slowest race time and the overall average race time.
