XYZ Corp.’s facilities in Nashua, New Hampshire, are two office buildings 400 feet apart, each with its own LAN. To connect the

two networks, you plan to dig a trench and lay cable in conduit between the two buildings. You want to use fiber-optic cable, but your budget-conscious facilities manager wants to use 100 Mbps Ethernet over twisted-pair cable. Which of the following reasons can you use to justify fiber-optic cable in this case, and why?
a: Twisted pair won't span a 400-foot distance ·
b: Fiber-optic cable is cheaper and easier to work with than twisted pair
c: Twisted pair is a conductive cable and can, therefore, carry current based on the difference in ground potential between the two buildings.
d: Fiber-optic cable leaves more room for growth and future needs for · increased bandwidth than twisted pair does

Answer:

a: Twisted pair won't span a 400-foot distance.

Explanation:

The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.

Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.

What is the printout of the call nPrint("a", 4)?
satela [25.4K]

Answer:

aaaa

Explanation:

We have a function nPrint which return type is void, it means it returns nothing.

we declare the two parameters, one parameter is string type and the second parameter is an integer type.

Then, it has a while loop that executes the statement again and again until the condition not FALSE.

Let dry run the code:

First, call the function nPrint("a", 4) bypassing the value in the argument.

then, the value receives by the parameters, the message contains "a" and n contain 4. After that, while loop checks the condition 4 > 0, which is TRUE and the program starts executing the statement.

The program prints the message on the screen "a" and then decreases the value of n by 1. So, the value of n becomes 3.

The above process repeats for the value of n = 3, 2, 1

and print the message "aaaa".

then, the condition becomes false and the program terminates the loop.

Therefore, the answer is aaaa

list2 = [1, 2, 3, 4, 5, 6, 7 ];

print "list1[0]: ", list1[0]

print "list2[1:5]: ", list2[1:5]

<h3>What is Python Lists?</h3>

This is known to be a list that is seen as the a most versatile in terms of datatype that are known to be available in Python.

It is one that can be written as a list of comma-separated values that is found in between square brackets.

Hence Creating a list is very simple to do and it is done by putting a lot of comma-separated values in between square brackets.

Therefore, An example of Read values into a list is:

#!/usr/bin/python

list1 = ['math', 'chemistry', 1995, 2001];

list2 = [1, 2, 3, 4, 5, 6, 7 ];

print "list1[0]: ", list1[0]

print "list2[1:5]: ", list2[1:5]

Discuss the main characteristics of the database approach and how it differs from traditional file systems.
Firdavs [7]

The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.

The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.
