Explanation:
The expressions are done with Java in answer above.
Answer: Networking protocols are important as they define a set of rules to be used for exchanging information between computer nodes.
Explanation:
in terms of networking it is required for the source and the destination to have a set of predefined rules which enables the router to send and receive information across the network in such as way that both the ends are able to receive the messages.
The information exchange takes place first by the client by introducing itself to the remote server. the remote server upon receiving the information uses some form of handshaking and acknowledges the client of the receipt of the message.
besides this there are many routing protocols which tells us about the way how packets are sent from the client to the source. There are two types of routing protocols:
1. static routing protocols
2. dynamic routing protocols.
Answer:
//Define class
public class Main {
//define main method
public static void main(String[] args)
{
//declare and initialize the double type variable to 128
double mexico = 128;
//declare and initialize the double type variable to 323
double us = 323;
//declare and initialize the integer type variable to 0
int yr = 0;
//set the while loop to check which is greater
while (mexico < us)
{
//increment in the variable by 1
yr++;
//initialize in the variables acc. to the percentage
mexico *= 1.0101;
us *= 0.9985;
}
//print the following results
System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");
System.out.println("Population of the Mexico will be " + mexico + " million");
System.out.println("and population of the U.S. will be " + us + " million");
}
}
<u>Output</u>:
Population of the Mexico will be exceed the population U.S. in81 years
Population of the Mexico will be 288.88435953355025 million
and population of the U.S. will be 286.0198193927948 million
Explanation:
<u>Following are the description of the program</u>.
- Firstly, we define the class 'Main' and inside it, we define the main method.
- Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
- Declare integer data type variable 'yr' and initialize in it to 0.
- Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
- Finally, print the following results with the message.
1. Less picture less distraction, but where to put pictures ? At the start of your presentation just to initially get the attention of the audience.
2. Use bullets for texts, never use paragraphs. Use short text or even words only which captures the subject of the presentation.
3. In conjunction with point 1. Use less animations as well. Especially for formal presentations
Additionally : Make sure to know your audience, for professionals, make the presentations short and precise. For much informal audiences you can be playful but always keep in mind not to overshadow the attention from the speaker.
