Based on the information, it is clear that the web server at the IP address is reachable, yet there may be a DNS goal issue for its space name. Option A and E is the correct answer
How is the web server part of the problem?The problem can be understood in two ways based on the information provided:
A. The web server at 192.168.0.10 is reachable from the source.
This is not entirely set in stone by the fruitful ping order reaction to the IP address of the web server. Assuming that the web server was inaccessible, the ping would fall flat.
E. DNS cannot resolve the IP address for the server web-s1.cisco.com.
This may be induced by the truth that the specialist utilized the IP address (192.168.0.10) rather than the space title (web-s1.cisco.com) to test the network. On the off chance that DNS was working appropriately, the expert would have utilized the space name all things being equal.
As a result, we are able to conclude from the exhibit that the web server at the specified IP address can be reached; however, there may be a problem with DNS resolution for the server's domain name.

This topology configuration allows the distribution of many of these signals, although one of the connexons starts going down.This topology needs to connect each destination to any other end destination, thus creating a completely pointless channel.Word Separator
Write a program that accepts as input a sentence in which all of the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."
Answers
Answer:
Following are the code to this question:
value=input("Enter string value: ")#defining string variable for input value from user
val= ""#defining another string variable val
i=0#defining integer variable and assign value 0
for x in value:#defining loop for proving spacing in value
if x.isupper() and i > 0:#defining if block to check value upper and greatern then 0
val+= " "#proving spacing in string value
val += x.lower()#convert another value into lower case
else:#defining else block
val += x#hold value in val variable
i += 1#increment i variable value
print (val)#print value
Output:
Enter string value: StopAndSmellTheRoses
Stop and smell the roses
Explanation:
In the above python code, a string variable "value" is defined that inputs the value from the user end, and another variable "val" is defined for saving calculated value.
In the next step, for loop is declared, that uses if block to check input value and convert the input value first letter into uppercase and print all value with space. If the condition is false it will return the user input value.

A user reports that he cleared a paper jam and now cannot print. The technician reseats the paper and then prints a test page from the printer. A test page sent from the workstation does not print. Which of the following actions should the technician take first?
a. Check the printer connection
b. Stop and start the printer
c. Reboot the computer
d. Clear the print queue
Answers
Answer:
d. Clear the print queue.
Explanation:
If a user reports that he cleared a paper jam and now cannot print. Also, the technician reseats the paper and then prints a test page from the printer. A test page sent from the workstation does not print. The first and most appropriate action the technician should take is to clear the print queue.
In computer technology, a printer is an electronic output device (peripheral) that is used for the printing of paper documents (texts and images).
The print queue is the directory or location where the printing sequence for a printer is stored or backed up. If it was ensured that the power cord of the printer is properly plugged in, the paper jam is cleared and the papers are properly seated, then the next action to take is clearing the printing queue. Once, the printing queue is cleared and becomes empty, the printer will begin to print.

Answers
Answer:
Following are the code to this question:
def binarynumber(num):#defining a method binarynumber that accepts a parameter num
x=""#defining a string variable x
if (num!=0):#defining if condition to check number not equal to 0
while (num>=1):#defining a loop that check value is grater then equal to one
if (num %2==0):#defining if condition to check num is even
x=x+"0" #add string value 0 in num variable
num=num/2 #divide the value by 2
else:#defining else block
x=x+"1"#add string value 1 in num variable
num=(num-1)/2#first subtract 1 into num variable then divide the value by 2
else:
x="0"#assign string value 0 in num variable
return "".join(reversed(x))#return value
num = int (input ("Enter any number: "))#defining num variable that input the integer value
print (binarynumber(num))#using print method to call method binarynumber with passing num parameter
Output:
Enter any number: 12
1100
Explanation:
In the above python code a method "binarynumber" is declared, in which the "num" variable passes as the parameter inside the method a string variable "x" is declared that stores all converted values. Inside the method and if the block is declared that checks number value is not equal to 0 if this condition is false then it will add string value and reverse its value. Or if the condition is true it defines a while loop that calculates the given number binary digits and returns its value. At the last step, the num variable is declared that inputs the integer value from the user end and calls the method by using the print method.Which of the following statements are true? Select one or more: a. A socket is a kind of opening. b. A socket represents one endpoint of a network connection. c. A program uses a socket to communicate with another program over the network. d. Data written by a program to the socket at one end of the connection is transmitted to the socket on the other end of the connection, where it can be read by the program at that end.
Answers
Answer:
a. A socket is a kind of opening.
b. A socket represents one endpoint of a network connection.
c. A program uses a socket to communicate with another program over the network.
d. Data written by a program to the socket at one end of the connection is transmitted to the socket on the other end of the connection, where it can be read by the program at that end.
Explanation:
A socket is an endpoint in the network node of a computer network that serves the role of sending and receiving data written by a program across the network. The application programming interface specifies the attributes of a socket, through the socket descriptor. The socket address serves the purpose of making the socket identifiable by other hosts.
The socket address consists of the transport protocol, IP address, and port number. Just like a port serves as the endpoint in hardware, so does the socket also function as an endpoint in a network connection.
(x - 1) (x² + x + 1)
Answers
Answer:
x³ - 1
Solution 1: We are given two expressions: the first is (x² + x + 1) and the second (x - 1). We multiply the two term by term till all the terms in the first expression are exhausted. Start with the x² term from the first expression, multiply it by x of the second expression and put down the product. Next you multiply the same x² term by -1 of the second expression and write the result. Repeat the process for the other two terms ( x and +1) in the first expression. Having completed the multiplication process, simplify and arrive at the final result.
∴ (x² + x + 1) (x - 1)
= [x².x + x² (- 1) + x.x + x(-1) + 1.x + 1(-1)]
= x³ - x² + x² - x + x - 1 ,which after cancellation of equal terms,
= x³ - 1 (Proved)
Solution 2: Here we use the relevant formula which may be quoted verbally as follows: The difference of the two cubes of any two quantities is equal to the product of two expressions, one of which is the difference of the two quantities, and the other the sum of their squares increased by their product.
If the two quantities are x and 1,
Then the difference of the cubes of x and 1 = x³ - 1³ = x³ - 1
One expression = difference of x and 1 = x - 1
Other or second expression
= (sum of squares of x and 1 + product of x and 1)
= x² + 1² + x.1 = x² + 1 + x = x² + x + 1
∴ By the above theorem
x³ - 1 = (x² + x + 1) (x - 1)

Explanation:
Using if in this way will validate one by one, and finding a true value will not validate the rest of "else if"
score = 68
if (score < 50) --> print "F"
68 < 50 --> falseelse if (score >= 50 OR score < 55) --> print "D"
68 > = 50 TRUE .... (The OR operator displays a record if any of the conditions separated by OR is TRUE)As this condition is true the system will not validate the other conditions
