The default subnet mask for a Class C address in classful addressing is 255.255.255.0.
Class A, Class B, Class C, Class D, and Class E are the five categories into which IP addresses are divided in classful addressing. Each class has a default subnet mask, which is used to distinguish between the parts of the IP address that indicate the network and the host.
The default subnet masks for Class A addresses are 255.0.0.0, Class B addresses are 255.255.0.0, and Class C addresses are 255.255.255.0. For Class D and Class E addresses due to their unique functions, there is no default subnet mask.
By applying the default subnet masks, classful addressing determines the range of IP addresses that can be used on a particular network. Classless addressing, which employs variable-length subnet masks, has taken the role of classful addressing in order to promote flexibility and improve the utilization of IP addresses (VLSMs)

Which of the following characteristics differentiate a rainbow table attack from a brute force attack? (Select two.)
A.
Rainbow table attacks greatly reduce compute cycles at attack time.
B.
Rainbow tables must include precomputed hashes.
C.
Rainbow table attacks do not require access to hashed passwords.
D.
Rainbow table attacks must be performed on the network.
E.
Rainbow table attacks bypass maximum failed login restrictions.
The two characteristics that differentiate a rainbow table attack from a brute force attack are Rainbow tables must include precomputed hashes and Rainbow table attacks bypass maximum failed login restrictions
B. Rainbow tables must include precomputed hashes: In a rainbow table attack, precomputed hashes are generated and stored in the table for quick lookup. These tables contain a set of precomputed hashes derived from a large number of possible passwords. The attacker compares the hashed passwords in the target system with the precomputed hashes in the rainbow table to find a match. This significantly reduces the compute cycles required during the attack compared to computing hashes on the fly.
E. Rainbow table attacks bypass maximum failed login restrictions: Rainbow table attacks can bypass maximum failed login restrictions because they involve comparing precomputed hashes rather than actually attempting login with different password guesses. This allows the attacker to quickly match the hashed passwords from the target system with the precomputed hashes in the rainbow table without triggering any failed login restrictions.
Therefore, the correct options are B and E.

differentiate between the purpose and results of meiosis i and meiosis ii
Meiosis is a type of cell division that typically only happens once in the lifespan of a eukaryote and is essential for eukaryotic organisms to reproduce.
What is Meiosis?Meiosis creates gametes, or sex cells, by rearranging and combining genetic information. This process guarantees that offspring (children) are genetically unique and that the gene pool has a suitable range of individuals.
Meiosis requires two division stages, known as meiosis I and meiosis II, because it starts with one diploid parent cell and finishes with four haploid daughter cells. Meiosis I is when genetic reassortment takes place.
Reductional division also occurs during the first meiotic stage, when a diploid parent cell divides into haploid daughter cells, resulting in a shift in ploidy. Because Meiosis II is an equational division, it lacks a change.
Therefore, Meiosis is a type of cell division that typically only happens once in the lifespan of a eukaryote and is essential for eukaryotic organisms to reproduce.

Explanation:
what code would be used to call a function called repeat every 3 seconds? A. settimeout(repeat, 3) B. setinterval(repeat, 3000); C. setinterval(repeat, 3)
D.; settimeout(repeat, 3000)
B. setinterval(repeat, 3000); To call a function repeatedly with a specified time interval, we can use the setInterval function in JavaScript. The correct code to call a function called "repeat" every 3 seconds is setInterval(repeat, 3000);.
In JavaScript, the setInterval function is used to repeatedly execute a function at a specified time interval. It takes two parameters: the function to be executed and the time interval in milliseconds.
Option A (setTimeout(repeat, 3)) is incorrect because setTimeout is used to execute a function once after a specified delay. In this case, the delay is only 3 milliseconds, which is too short for a repeated execution.
Option B (setInterval(repeat, 3000)) is the correct choice. It calls the function repeat every 3000 milliseconds (or 3 seconds), creating a recurring interval.
Option C (setInterval(repeat, 3)) is incorrect because the time interval is set to only 3 milliseconds, which is too short for a noticeable delay between function calls. This would result in a very high frequency of function calls.
Option D (setTimeout(repeat, 3000)) is similar to Option A, but it would only execute the function repeat once after a delay of 3000 milliseconds, rather than repeatedly every 3 seconds.
Therefore, the correct code to call the function "repeat" every 3 seconds would be setInterval(repeat, 3000);.

uppose that a tcp segment has a lifetime of 2 minutes in the network. calculate the maximum transmission speed (bits/second) at which a host can send out 1460-byte tcp segments so that there will not be two tcp segments from the same sender with the same sequence number in the network, i.e., without having the tcp sequence numbers wrap around?
The maximum transmission speed at which a host can send out 1460-bytes TCP segments from the same sender with the same sequence number in the network exists at 10 bits per second.
How to estimate the sustained maximum data transfer rate?If the bandwidth exists at 10 Gbps, the link will be (10/8) 109 bps = 1.25 109 bps.
120 seconds is the maximum segment lifetime.
The amount of data transferred in 120 seconds exists equivalent to 150 1.25 109 bps / 120. 1.5 x 1010 bytes Equals 109 bytes
The TCP will generate a 1.5 1010 sequence number in the 120 seconds.
One is required to transfer data at the highest speed to make a 1.5 × 1010 unique sequence.
= ceiling(log(1.5 1010)
= ceil(log(1.5) + log(1010))
= ceil(0.1761 + 10)
= ceil(10.1761) (10.1761)
= 10 bits in the field for the sequence number.
Therefore, a sustained maximum data transfer rate of 10 bits per second exists required between two hosts.

which of the following are ways in which tcp detects congestion? (check all that apply) group of answer choices the destination host sends an icmp message to the sender when the network is congested. congestion is inferred when there are too many timeouts on sent packets. congestion can be detected only after congestion collapse has occurred. tcp monitors the network utilization, and infers congestion when utilization exceeds 80%.
The ways in which TCP detects congestion are: Congestion is inferred when there are too many timeouts on sent packets: When packets are lost or not acknowledged within a certain timeout period, it is an indication of network congestion.
TCP interprets these timeouts as a sign of congestion and adjusts its congestion control mechanism accordingly.
TCP monitors the network utilization and infers congestion when utilization exceeds 80%: TCP keeps track of the network's available bandwidth and compares it with the current utilization. If the utilization exceeds a certain threshold, typically around 80%, TCP assumes that congestion is occurring and reacts by reducing its sending rate.
So the correct options are: Congestion is inferred when there are too many timeouts on sent packets.
TCP monitors the network utilization and infers congestion when utilization exceeds 80%.

To write a Java program to find the maximum and minimum numbers without using arrays, you need to follow the following steps:
Initialize the maximum and minimum variables to the first number.Read the numbers one by one from the user and compare them with the current maximum and minimum numbers.If a new maximum or minimum number is found, update the corresponding variable.
Print the maximum and minimum numbers as output.In the above program, the user is prompted to enter the first number. This number is then used to initialize the max and min variables. The program then enters a loop where it reads more numbers from the user and updates the max and min variables as necessary.
The loop continues until the user enters 0, at which point the program prints the maximum and minimum numbers.

this superclass has the following abstract method: public abstract int getvalue(); write a getvalue method that could appear in one of its subclass and returns the integer val.
Subclasses must implement abstract methods of their superclass. In this case, the subclass can define its own implementation of the "getvalue" method that returns the desired integer value.
If a superclass has an abstract method named "getvalue" that returns an integer, any subclass that extends this superclass must implement the "getvalue" method. To do so, the subclass can define its own implementation of the "getvalue" method that returns the desired integer value, such as:
public class Subclass extends Superclass {
// other class members here
public int getvalue() {
int val = 42; // or any other desired integer value

Can the laptop receive a memory upgrade and if so, how much will it cost?
Due to the laptop's dual-channel memory arrangement, which allows it to use two SO-DIMMs simultaneously, Windows reports 8 GB of memory.
Each SO-DIMM in this instance is delivering 4 GB of memory, making a total of 8 GB available. The OS and the game are considerably more knowledgeable about how the RAM should be maintained and what assets should be moved where than you or I am.
High RAM use is in no way harmful. You don't pay for 8GB to utilize only 2GB, do you? In that case, purchase 2GB instead. Never worry about RAM utilization unless an unknown app is using too much and preventing the use of other system features or capabilities.
