Explanation:

One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.

Fill a rectangular baking glass dish with water.

Place a plastic bag with ice in the water near the left edge of the dish.

Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.

Put a few drops of ink in the water.

The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)

Not enough ink was added.

Not enough water was taken.

The dish was too small for the experiment.

The lamp and the ice bag were at the same place.

Blocking ransomware

Explanation:

A ransomware is a malware that acts by encrypting the files of a victim after which the attacker demands for a ransom payment to be made by the victim before access is restored through the provision of a key to decrypt the encrypted files

There are different types of ransomware such as blockers, wipers and cryptors

A blocker ransomware is one that blocks access to the files stored on a computer or device by encrypting them and usually displaying a demand for payment message that comes up in front of the all opened windows

How is a UDP socket fully identified? What about a TCP socket? What is the difference between the full identification of both so

vekshin1

Answer:

Following are the solution to this question:

Explanation:

Two tuples were fully identified only with UDP socket.:

< IP address assigned, the port for destination >

Its two tuples have been used in UDP as demux, buttons to identify its UDP socket.

The IP address for the destination:

Its received data is directly provided by the IP address of its port.

Port number of the destination:

The function of the IP address of its port number whenever you obtain a UDP segment would be to control the IP addresses of a segment or send that segment to a port with the same IP address. Its port number for endpoint allows demultiplexing incoming information from its IP.

TCP socket is completely recognized by the following four tuples:

< source IP, port source, IP source, port location >

It tuples are being used to label the sockets by using a demultiplexing (demux) key.

IP address source:

The IP address is being used to identify the unique host that links to. It can assume that perhaps the source IP address shows us all the source Addresses of the sender.

Port number of source:

Its port number amount allows us to identify which section is arriving at which port.

IP address destination:

Its IP address of a destination is the IP address of a port accepting incoming information.

Port number of the destination:

It is port numbers number allows us to identify the facilities or section should be sent to.

Differentiation between TCP and UDP identifier:

As TCP ports (4 tuples) and UDP ports (2 tuples) are using demux keys to define socks, however, demux keys in UDP are unique from others in TCP for both the following reasons:

TCP uses a separate socket for every contact between both the server and client whereas UDP utilizes its same sockets to process all clients accessed by UDP servers with all communications, it maintains TCP is much more dependable and hence has to hold a different port.

Even so, UDP doesn't accomplish things apart from multicasting and demodulation, but no separate port is necessary by each link. Therefore the TCP socket becomes connection-driven as well as the UDP socket is direct link-free.

Design a loop that asks the user to enter a number. The loop should iterate 10

yarga [219]

There are actually a couple of questions in here. I'll try to answer them in Python, which kind of looks like psuedocode already.

1. Design a loop that asks the user to enter a number. The loop should iterate 10 times and keep a running total of the numbers entered.

Here, we declare an empty array and ask for user input 10 times before printing a running total to the user's console.

numbers = []

for i in range(10):

numbers.append(input("number: "))

print(f"running total: { ', '.join(numbers) }")

2. Design a program with a loop that lets the user enter a series of numbers. The user should enter -99 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.

Here, we declare an empty array and ask for user input forever until the user types -99. Python makes it really easy to get the min/max of an array using built-in functions, but you could also loop through the numbers to find the smallest as well.

numbers = []

while True:

n = int(input("number: "))

if n == -99:

break

numbers.append(n)

print(f"largest number: { max(numbers) }")

print(f"smallest number: { min(numbers) }")
