a)
DNS:
DNS stands for Domain Name System. It is the way that internet domain names are located and translated into internet protocol address.
TCP:
TCP stands for Transmission Control Protocol which is a standard that establishes and maintain a network conversion with the use of application programs.
Round Trip Time (RTT):
The length of time it takes for a signal to be sent along with the length of time to be acknowledged is called the round trip time.
There are “n” DNS servers in the connection.
Amount of elapsed time:
While clicking on a link to open a web page, the IP address of the associated web page is not cached in the local host and hence a DNS lookup is used to identify the local host.
As the webpage is not cached and therefore must be found before the file can be requested and then received by the contacting host.
It is given that visits to “n” DNS servers to find the site occur a round-trip time (RTT) which adds up to “RTT1, RTT2,… RTTn” ,in which the numbers of RTT represents the DNS number.
- Therefore the total time it takes for the host to obtain the IP address can be denoted as: “RTT1+RTT2+RTT3+…RTTn”.
Given Data:
The HTML file references eight very small objects on the same server.
To Find:
Non Persistent HTTP with no parallel TCP connections:

- Can you please show me how I can do this on google sheets. For the spreadsheet you need to create a multi page sheets thing that uses all the techniques of counts/sums and graph showing how many contracts have been returned for each grade...you can make up the data (let's say in grade 9 I got 15 contracted back with fake data that I want you to show me how to create on google spreadsheet) For grade 10 i got 20 contracts signed, for grade 11 I got 16 contracts and for grade 12 I got 25 contracts back. Can you help me pls. Thanks so much. Make sure you have graphs on the page and also the sum written as a formula and the numbers filled in the columns.arrow_forwardI need help with this problem and an step by step explanation of the solution from the image described below. (Introduction to Signals and Systems)arrow_forwardGoal: Understand how to build a concurrent server and deal with signals Description: Use TCP socket programming in C to implement a pair of client and server programs. The client simply asks the user to enter a string (null-terminated), and then displays a menu for the user to select an operation on that string. The string and the type of operation are sent to the child server which performs the required operation and returns the result back to the client. That is, the server (parent) creates a child for each request of the client (you need to print the port and IP address of the client on the server terminal). Then it waits for the child to finish processing client's request and prints the process ID of the terminated child. The connection between your client and server should stay open, so that the client can send another request. However, the exit will happen when the user sends the client program the SIGQUIT signal. The handler will print a notifying message (for example, "Good…arrow_forward
