Chapter 4, Problem P9P
Program Plan Intro
Datagram:
- In networking, a datagram is a transferring unit which is used to transfer the data from a source to the destination and it doesn’t provide guaranteed service.
- It includes fragmentation process which is defined as the division of the data packet into small one when the data packets are larger than the maximum length of a particular system.

Write a script using PHP that takes a link from the user and parses through its associated web page to print a list of every link embedded on that site. This program must work recursively, so for each link that gets printed, the program should automatically take each of those links as a new input and do the same for them until there are no more links left. If the same link exists twice on the same page, or if it exists on more than one page, the program should ignore all duplicate instances of the link.

My main piece of code thus far is n is an int please show me how to write the code for this.arrow_forwardWrite a Perl program that uses a hash and a large number of operations on the hash. For example, the hash could store people's names and their ages. A random-number generator could be used to create three- character names and ages, which could be added to the hash. When a duplicate name was generated, it would cause an access to the hash but not add a new element. Rewrite the same program without using hashes. Compare the execution efficiency of the two. Compare the ease of programming and readability of the two.arrow_forwardNote: Please answer in C++ Code An input string S of length N is transferred through the network using a special protocol. The protocol can send the string through a series of operations. In one operation, we can choose a lowercase english alphabet and do one of the following: Transfer 1 copy of C through the network. Transfer 2 copies of C through the network. Each of the above transfers take 1 unit of time. Find the minimum time in which we can transfer the entire string S through the network.

- You are the designer of a transfer protocol to send/receive a file between two computers. The sender divides the file into smaller frames to be sent sequentially to the receiver, and there are two options to make sure that receiver receives the file correctly: The sender can send frame n+1 if receives an ACK on frame n from the receiver (e.g., sender receives ACK on frame 2, so will proceed and send frame 3). The sender sends all the frames sequentially and the receiver will send only one ACK if the entire file is received successfully. Which approach, from your point of view, is efficient and why - If we have: noisy communication channel (there is high probability of more than one device speak at the same time, high probability of interference). non-noisy communication channel.arrow_forwardSuppose the alphabet is {I, V, X}.

Consider a communication system that uses 7 bits out of every byte to transmit data, and reserves the 8th bit (the one on the right) to transmit the parity of the other seven bits, for purposes of error checking. Below is the binary representation of some bytes that were transmitted using this system. For each one, tell whether there is a reason to suspect an error in transmission, giving the reason for your answer. 10110011 11101111 10101100 00110011arrow_forward

A Caesar cipher performs a shift ofall of the characters in a string (based on their ASCIIvalues, see Table 2.1), e.g.h e l l o → m j q q tThe example shows a shift with a distance of 5characters, i.e. h(ASCII:104) → m(ASCII:109)Write a C/C++ program that asks the user to input aline of plaintext and the distance value and outputsan encrypted text using a Caesar cipher, with theASCII values range from 0 through 127. Useunderscores (ASCII: 95) to represent spacecharacters.Underscore characters should not be encrypted,and any character that is encrypted may notbecome an underscore. In this case, the charactershould be changed to the next character in theASCII table.The program should work for any printablecharacters.NB: No strings (datatype) or library functions maybe used.See Figure 2.1 for example output.arrow_forward
- A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. • The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. • The script shiftRight performs the inverse operation. • Each script prints the resulting string. An example of shiftLeft.py input and output is shown below: Enter a string of bits: Hello world! ello world!H An example of shiftRight,py input and output is shown below: Enter a string of bits: Hello world! !Hello worldarrow_forward***Posting this for the second time as the previous solution was in correct. *** Please solve it correctly and please provide explanation of your answers. Answers to parts form (a) to (f) are given in bold for your convinience. Please answer from part (g). Please don't give incorrect answer. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was…arrow_forwardIn XOR Cipher, encoding is done by an XOR operation on two given strings. If the strings are of different lengths then the output should be the length of the shorter string. Cut the length of the longer string to the same size as the smaller string before XOR operation. Given two strings of msg1 and msg2, return the encoded message. Examples xor_cipher ("11", "22") "33" # 11 XOR 22 = 33 RUBY xor_cipher ("1020304", "403201") xor_cipher ("c611d9bdd9de38b9eb", "23a0745505d4d25494") "e5b1ade8dc0aeaed7f" "501231"arrow_forward
