Suppose end system A wants to send a large file to end system B, the large file is first divided into smaller chunks.
Each chunk is then assigned a header forming a packet. Multiple packets are being generated with each of the packet containing a unique destination address in its header.
When a packet arrives at the packet switch, the switch uses the unique destination address that is attached in the header of the packet to determine the link onto which the packet is to be forwarded.
Packet switching is transfer of small pieces of data across various networks. These data chunks or the “packets” allow for faster, more efficient data transfer.
It is the method by which the internet works, it features delivery of packets of data between devices over a shared network. For example school web server sending you a webpage over the internet or you sending an email to a friend.

If end system A wishes to send a large file to end system B, the file must first be broken up into smaller pieces.
Describe how end system a creates packets from the file. when one of these packets arrives to a router ?After that, a header is given to each chunk, creating a packet. A distinct destination address is included in the header of each of the multiple packets that are being generated.
What information in the packet does the router use to determine the link onto which the packet is forwarded?The unique destination address in the packet's header is used by the packet switch to determine the link onto which the packet is to be forwarded when it arrives at the switch.
Why is packet switching in the internet analogous to driving from one city to another and asking directions along the way?The transfer of small amounts of data between various networks is known as packet switching. The "packets," or data chunks, make it possible to transfer data more quickly and effectively. It is how the internet works, and it involves sending data packets between devices over a shared network.

YES: A ball deflected by a defender is received by an attacker who is offside at the time of a teammate's touch. This is an offside offense.
Explain the term offside offense?In plain English, a player gets offside if they're in the offensive half as well as closer to the goal line of the opposing team than the ball and the player after them.
Any part of a player's head, body, or feet that is inside of the opponent's half (outside of the halfway line) or that is closer to the opponent's goal line than both ball and the last opponent are considered to be in an offside position.Example: When the ball is passed, the red attacking player has already passed the final defence.

a folder contains nencrypted files of which one is a special file. an attacker has access to the folder and withdraws kof these files one at a time. each selection is equally likely to be any one of the remaining files at the time. what is the probability that the intruder withdraws the special file?
The probability that the intruder withdraws the special file is 1/k.
What is the probability that the intruder withdraws the special file?The probability that the intruder withdraws the special file is dependent on the number of encrypted files in the folder and the number of files the intruder withdraws. If the folder contains n encrypted files and the intruder withdraws k of them one at a time, then the probability of the intruder withdrawing the special file is (1/n)^k. This means that the probability that the intruder withdraws the special file is increasing as the number of files in the folder decreases and the number of files the intruder withdraws increases.For example, if the folder contains 10 encrypted files and the intruder withdraws 5 of them one at a time, then the probability that the intruder withdraws the special file is (1/10)^5 or 0.0009765625. This means that the chances of the intruder withdrawing the special file are quite low, but not impossible.In general, the probability that the intruder withdraws the special file is inversely proportional to the number of encrypted files in the folder and proportional to the number of files the intruder withdraws. Therefore, the more files the intruder withdraws, the higher the probability that the special file will be withdrawn. Conversely, the more files that are in the folder, the lower the probability that the special file will be withdrawn.To learn more about dividing probability refer to:

Assuming a growth function f(n) exists, f(0) denotes the growth function's starting point (n). To put it another way, f(0) stands for the general cost of running the algorithm on an empty input.
What is a growth function in data structures?Growth functions are used to predict how many steps an algorithm will take as its input increases. The order of growth of an algorithm provides a rough estimate of the amount of time needed to run a computer program as the quantity of the input rises.
The sequence of growth ignores the constant factor required for fixed processes in favor of the operations whose output size grows proportionately. Exponential algorithms are only effective for minor issues since exponential functions expand rapidly.

which sharing method should you use if you want to configure share and ntfs permissions for a user in a single process?
Answer:
If you want to configure share and NTFS permissions for a user in a single process, you should use the Security tab in the Properties window for the shared folder.
To access the Security tab:
Right-click on the folder you want to share and select Properties
Click on the Sharing tab and then click on the Advanced Sharing button
Click on the Permissions button to access the share permissions
Click on the Security tab to access the NTFS permissions
By using the Security tab, you can add or remove users and groups, and set their corresponding permissions for both the share and NTFS levels. This allows you to configure both types of permissions in a single process, rather than having to do them separately.
Note that while this method allows you to manage both permissions in one place, it's important to keep in mind that Share and NTFS permissions are different and that the most restrictive permission will always apply. It's important to test and ensure the correct permissions are set up.
