Answer:
TDMA: Time-division multiple access (TDMA) will operate effectively.
CSMA: Carrier-sense multiple access (CSMA) will NOT operate properly.
Slotted Aloha: Slotted Aloha will NOT perform effectively.
Token passing: Token passing will operate effectively.
Explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Suppose you were charged with putting together a LAN to support IP telephony (only) and that multiple users may want to carry on a phone call at the same time. Recall that IP telephony digitizes and packetizes voice at a constant bit rate when a user is making an IP phone call. How well suited are these four protocols for this scenario?
TDMA:
CSMA:
Slotted Aloha:
Token passing:
Provide a brief explanation of each answer.
The explanation of the answers is now provided as follows:
TDMA: Time-division multiple access (TDMA) will operate effectively in this situation because it provides a consistent bit rate service of one slot every frame.
CSMA: Because of collisions and a changing amount of time to access the channel, Carrier-sense multiple access (CSMA) will NOT operate properly in this situation. Also, the length of time it takes to access a channel is not limited.
Slotted Aloha: Just like CSMA, Slotted Aloha will NOT perform effectively in this situation because of collisions and a different amount of time to access the channel. Also, the length of time it takes to access a channel is limitless.
Token passing: Token passing will operate effectively in this case because each station has a turn to transmit once per token round, resulting in a service with an effectively constant bit rate.

Write a program that randomly chooses among three different colors for displaying text on the screen. Use a loop to display 20 lines of text, each with a randomly chosen color. The probabilities for each color are to be as follows: white 30%, blue 10%, green 60%. Suggestion: Generate a random integer between 0 and 9. If the resulting integer falls in the range 0 to 2 (inclusive), choose white. If the integer equals to 3, choose blue. If the integer falls in the range 4 to 9 (inclusive), choose green. Test your program by running it ten times, each time observing whether the distribution of line colors appears to match the required probabilities.

b. CIDR address format represents a Class C network only used within an intranet.
c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.
Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.
What is an IP address?A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.
Only C is correct, rest other statements are incorrect because:
a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.
b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.
Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);
Answer:
The true statements are :
A. assertEquals(student1,student2)
C. assertSame(student1,student3)
Explanation:
AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.
Methods are collections of named code segments that are executed when evoked
The assertion method that will return true for the given code is: assertEquals(student1,student2)
The code segment is given as:
Student student1 = new Student();
Student student2 = new Student();
Student student3 = student1;
In Java, the assertEquals() method returns true if two objects have equal values.
Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

Write a program that reads in an integer, and breaks it into a sequence of individual digits. Display each digit on a separate line. For example, the input 16384 is displayed as 1 6 3 8 4 You may assume that the input has no more than five digits and is not negative.
Answer:
The program in Python is as follows:
num = int(input())
for i in str(num):
print(int(i))
Explanation:
This gets input for the number
num = int(input())
This converts the number to string and iterates through each element of the string
for i in str(num):
This prints individual digits
print(int(i))
I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?
a. hard drive is full
b. photos were taken in a different country
c. USB port is broken
d. the file structure of the 2 hard drives are not compatible
The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.
The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.
Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:
JPEGPNGJFIFAny external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.
The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false
Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:
"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.
