Answer:
The answer to this question can be given as:
Class definition:
public class Averager //define class Average.
{
private int sum = 0;
//define variable sum.
private int count = 0;
//define variable count.
public int getSum() //define function getSum().
{
return sum; //return value.
}
public void add(int x)
//define function add().
{
sum = sum + x; //calculate sum
count=count+1; //increase value of count.
}
public int add(int x)
//define function add().
{
return count; //return value.
}
public double getAverage() //define function getAverage().
{
return (double)sum/count; //return value
}
}
Explanation:
The above class definition can be described as:
- In the above class definition first we define a class that is " Averager". In this class we define two integer variable that is "sum and count" and assign a value that is 0. Then we define a functions :
- First we define getSum() function in this function we does not pass any value and the return type of this function is int that will return an integer value.
- Then we define add() function we use this function two times but both functions have different from each other.
- In first time implementation, we define this function and the return type of this function is void which means it does not return any value. In this function, we calculate the sum value and increase the value of the count variable by 1.
- In second time implementation, we define this function and the return type of this function is int which means it will return a value. In this function, we will return the count variable value.
- At the last, we define a getAverage() that calculates the average of the added values in the sum variable and returns its value.
Answer: Amazon DynamoDB
Explanation:
The database technology that is best suited to hold the session state in this example is the Amazon DynamoDB.
Amazon DynamoDB is a document database which helps in delivering high quality and fast cperformance at any scale. It can be used to scale to hundreds of thousands of concurrent users as it's multi-active, and has a durable database that has built-in security.
Answer:
No padding
Explanation:
64 bytes is taken as the minimum Ethernet frame, this encompass checksum as well as addresses in the Ethernet frame header and length field. while the maximum Ethernet frame is 1518 bytes, any minimumEthernet frame that is short compare to that will need receiving stations to interpret it as a collision. The question specified that the IP packet to be transmitted by Ethernet as 60 bytes long. The header fields here can occupy 18 bytes, Then total frame size becomes 78 bytes. With the total frame size of 78 bytes(60 bytes+ 18 bytes) we can see it has exceeded the 64-byte minimum. Hence there is no padding used.
