Answer:

In a broadcast network such as radio network for example a walkie talkie, the broadcasted transmission is received equally by all receivers indiscriminately which may lead to dissemination of classified information to an unauthorized receiver, therefore, the network layer is required is needed to ensure proper routing of the information

Similarly, when the all the broadcasters in one location are each trying to send messages to different receivers at another given location, there would be potential for network congestion and it would be difficult to send information through the network

When there is need for priority service the presence of a network layer is needed in the network

However, when the above functions performed by the network layer is not required, then, the network layer can be excluded, such as the communication between layers 4 - 7 of the OSI model

Summary In this lab, you declare and initialize variables in a C++ program. The program, which is saved in a file named NewAge.c
AVprozaik [17]

Answer:

<em>#include <iostream></em>

<em>using namespace std;</em>

<em>int main()</em>

<em>{</em>

<em>  int myNewAge;</em>

<em>  int myCurrentAge = 29;</em>

<em>  int currentYear = 2020;</em>

<em> </em>

<em>myNewAge = myCurrentAge+(2050-currentYear);</em>

<em />

<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>

<em>    return 0;</em>

<em>}</em>

Explanation:

The program is written in C++ language as required. firstly, we declare the three variables:

<em>  </em><em>int myNewAge;</em>

<em>  int myCurrentAge = 29;</em>

<em>  int currentYear = 2020;</em>

Then we calculate the new age as: <em>myNewAge = myCurrentAge+(2050-currentYear);</em>

Using multiple cout operators (<em> </em><<) we display the output nicely as required by the question with this statement

<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>

Answer:

You need to understand all the network typologies and the devices that we use in the Computer networks. You also use the techniques like routing, masking, firewalls, VPN, as well as the network protocol. And recently added is the PKI. And hence you need to make sure that you know all these, and you should also know ipv4 and ipv6. Rest you can consult Tanenbaum for further studies on Computer Network.

Write a Python program string_functions.py that defines several functions. Each function re-implements Python's built-in string
Svetach [21]

Answer:

def length( mystring):

   count = 0

   for i in mystring:

       count += 1

   return count

def reversed( mystring):

   strlist = []

   for i in range(length(mystring)):

       strlist.append(mystring[(length(mystring) - 1) - i])

       txt = "".join(strlist)

   return txt

string = 'Yolanda'

print(reversed(string))

Explanation:

The python module defines two functions 'reversed' and 'length'. The length function counts the number of characters in a string variable while the reversed function reverses the string variable value.
