Write a program that prints out the last few lines of a file. The program should be efficient, in that it seeks to near the end of the file, reads in a block of data, and then goes backwards until it finds the requested number of lines; at this point, itshould print out those lines from beginning to the end of the file. To invoke the program, one should type: mytail -n file, where nis the number of lines at the end of the file to print.

tegan works for an isp and has been asked to set up the ip addressing scheme for a new region of the city they are providing with internet service. she is provided the class b address of 141.27.0.0/16 as a starting point and needs at least 25 subnets. what is the custom subnet mask for this, how many networks does this allow for, and how many hosts will be available on each subnet

Answers

The custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.The custom subnet mask would allow for four (4) subnets.There are 16 host bits available on each subnet.

What is a custom subnet mask?

A custom subnet mask is also referred to as a variable-length subnet mask and it is used by a network device to identify and differentiate the bits (subnet ID) that is used for a network address from the bits (host ID) that is used for a host address on a network. Thus, it is typically used when subnetting or supernetting on a network.

Given the following data:

Class B address = 141.27.0.0/16Number of subnets = 25.

Since the IP address is Class B, there are 16 bits for the subnet ID (141.27) while 16 are for the host ID. Thus, the custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.

2. The custom subnet mask would allow for four (4) subnets.

Which statement is true of Voice over Internet Protocol (VoIP)? a. Callers can be screened even with blocked caller IDs. b. Calls cannot be forwarded by users. c. Voicemails are not received on the computer. d. Users often experience busy lines.

Answers

Answer:

a. Callers can be screened even with blocked caller IDs.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. Some of the most widely used communication channel or medium over the internet are an e-mail (electronic mail) and Voice over Internet Protocol (VoIP).

Voice over Internet Protocol (VoIP) is also known as IP Telephony and it's a type of communication technology which typically involves the use of broadband connection for the transmission of voice data between two or more people. Thus, it requires the use of internet enabled devices such as smartphones, computers, IP phones, etc.

Blocking a number with the VoIP technology prevents the blocked user from calling or contacting your line. However, you can still screen or carry out some investigations with respect to the blocked number through Voice over Internet Protocol (VoIP).

Hence, the statement which is true of Voice over Internet Protocol (VoIP) is that, callers can be screened even with blocked caller IDs.

Brianna Watt, a consultant doing business as Watt Gives, wants a program to create an invoice for consulting services. Normally, she works on a project for five days before sending an invoice. She writes down the number of hours worked on each day and needs a program that asks for these amounts, totals them, and multiplies the amount by her standard rate of $30.00 per hour. The invoice should include Brianna’s business name, the client’s business name, the total number of hours worked, the rate, and the total amount billed. The information will be displayed onscreen. Using pseudocode, develope an algorithm to solve this program. Include standard documentation and comments.

Answers

Answer:

The pseudocode is as follows:

Total_Hours = 0

Input Client_Name

Rate = 30.00

For days = 1 to 5

      Input Hours_worked

      Total_Hours = Total_Hours + Hours_Worked

Charges = Rate * Total_Hours

Print "Brianna Watt"

Print Client_Name

Print Total_Hours

Print Rate

Print Charges

Explanation:

This initializes the total hours worked to 0

Total_Hours = 0

This gets input for the client name

Input Client_Name

This initializes the standard rate to 30.00

Rate = 30.00

This iterates through the 5 days of work

For days = 1 to 5

This gets input for the hours worked each day

      Input Hours_worked

This calculates the total hours worked for the 5 days

      Total_Hours = Total_Hours + Hours_Worked

This calculates the total charges

Charges = Rate * Total_Hours

This prints the company name

Print "Brianna Watt"

This prints the client name

Print Client_Name

This prints the total hours worked

Print Total_Hours

This prints the standard rate

Print Rate

This prints the total charges

Print Charges

Explanation:

In the code provided, we are creating an array of size 6 to store integer values. The objective is to populate this array by taking input from the user for specific indexes chosen randomly.

To achieve this, we have defined two methods: populateArray and printArray.

The populateArray method takes an array as a parameter and fills it with values provided by the user. Here's how it works:

We create an instance of the Random class to generate random numbers and a Scanner object to read user input.We also create a boolean array called filledIndexes of the same size as the main array. This array will keep track of the indexes that have already been filled.Next, we use a loop to iterate six times (since we want to fill six elements in the array).Inside the loop, we generate a random index using random.nextInt(6). However, we want to make sure that we don't fill the same index twice. So, we check if the index is already filled by checking the corresponding value in the filledIndexes array.If the index is already filled (i.e., filledIndexes[index] is true), we generate a new random index until we find an unfilled one.Once we have a valid, unfilled index, we mark it as filled by setting filledIndexes[index] to true.We then prompt the user to enter a value for the chosen index and read the input using scanner.nextInt(). We store this value in the main array at the corresponding index.This process is repeated six times, ensuring that each index is filled with a unique value.

The printArray method is responsible for printing the contents of the array. It uses a for-each enhanced loop to iterate over each element in the array and prints its value.

**By separating the population and printing logic into separate methods, the code becomes more modular and easier to understand.**

Create a program that will compute the voltage drop across each resistor in a series circuit consisting of three resistors.

All values should be accompanied by appropriate messages identifying each. Submit a printout of your program and the printed output to your instructor

Answers

Answer:

The program in Python is as follows:

R1 = int(input("R1: "))

R2 = int(input("R2: "))

R3 = int(input("R3: "))

   

Rt = R1 + R2 + R3

Vs = int(input("Circuit Voltage: "))

It = Vs/Rt

V1= It * R1

V2= It * R2

V3= It * R3

print("The voltage drop across R1 is: ",V1)

print("The voltage drop across R2 is: ",V2)

print("The voltage drop across R3 is: ",V3)  

Explanation:

The next three lines get the value of each resistor

R1 = int(input("R1: "))

R2 = int(input("R2: "))

R3 = int(input("R3: "))

This calculates the total resistance    

Rt = R1 + R2 + R3

This prompts the user for Circuit voltage

Vs = int(input("Circuit Voltage: "))

This calculates the total circuit voltage

It = Vs/Rt

The next three line calculate the voltage drop for each resistor

V1= It * R1

V2= It * R2

V3= It * R3

The next three line print the voltage drop for each resistor

print("The voltage drop across R1 is: ",V1)

print("The voltage drop across R2 is: ",V2)

print("The voltage drop across R3 is: ",V3)
