2 tcp segments will the side that initiates the connection send during a connection opening.
What is TCP?
Transmission Control Protocol (TCP) is a connection-oriented communications protocol that allows computing devices in a network to exchange messages. It is the most commonly used protocol in Internet Protocol (IP) networks; the two are sometimes referred to as TCP/IP.
TCP divides messages from an application/server into packets, which are then forwarded to the destination by network devices like switches, routers, and security gateways. TCP reassembles and numbers each packet before sending it to the application/server recipient. Because it is connection-oriented, it ensures that a connection is established and maintained until the exchange between the application/servers sending and receiving the message is complete.

You MUST use pointers and dynamic allocation to complete the following exercise to receive points. Write a program that takes a positive integer as input, indicating the number of integers (separated by whitespaces) that will follow. (1) Create a dynamic integer array with the size equal to the value of the first input integer to store the user input values. If the first input integer is not positive, the program will output "Invalid size!" and exit. (2) Find and print out the maximum even number and maximum odd number in the entered integer array. Ex: if the input is: 5 43 5 0 23 9 the program would output: The maximum even number is 0 The maximum odd number is 43 You MUST define and call the following two functions to return the memory addresses of the elements that store the maximum even number and maximum odd number, respectively.

You are testing a printer you just installed, so you use the operator panel on the printer to print a test page. Later, you use the printer properties on your computer to print a test page. Instead of a normal test page, you receive several pages with garbled characters on them. What is the most likely cause of the problem?
Wrong print drive.
Explanation
When you print a test page from your computer and it does not work properly, you most likely have an incorrect print driver or a printer cable that is not fastened properly. Memory or power supply problems are rare in printers. You would probably not be able to install an incorrect toner cartridge into the printer.
Since you are testing a printer you just installed, so you use the operator panel on the printer to print a test page, the thing that is the most likely cause of the problem is Wrong print drive.
What does the print driver do?The printer driver is software that is one that helps or enables communication between the computer and the printer and transforms computer data into a printable format.
Note that the program is downloaded from the creator and installed either on a single computer or on a server that will be accessed by many machines.The majority of printers need the most recent printer driver to function properly.
Therefore, based on the context of the question, If you print a test page from your computer and it does not print correctly, you probably have a bad print driver or a loose printer cord. Printer issues with memory or power supplies are uncommon. It's unlikely that you could put the wrong toner cartridge in the printer.

modify the lucsorter class (specifically the evenodd method) to reorder an array to have all the even elements followed by the odd elements. this will be similar to the selection sort algorithm (in this case, every odd element k found from left to right should be swapped with the first even number at the right of k). the even elements should be in the same order as they are in the input array, while the odd numbers are not required to be in the same order as in the input.
Pointers can be very useful when working with arrays.
What is Pointer Notation and Arrays?It's a frequent misperception that a pointer and an array can be used interchangeably. A pointer is not the name of an array. Although an array name can occasionally be treated as a pointer and pointers can be used with array notation, they are two separate concepts that are not always interchangeable. Knowing the distinction will help you avoid using these notations improperly. As an illustration, even if using an array's name alone would produce the array's location, we cannot use the name alone as the target of an assignment. A basic data structure that is included in C is an array. To create successful applications, it is essential to have a basic understanding of arrays and how they are used.This is demonstrated in the following code sequence where each row’s address and size is displayed:

Fill in the missing parts to produce the following output. Output: 0 1 2 3 num in range( ): print (num).
The answer is 4. For loops function a little bit differently in Python than they do in languages like JavaScript or C, as described in Python's documentation.
A for loop repeats the code in the body of the for loop for each value of the iterator variable, setting the iterator variable to each value in a given list, array, or string. The body of a for loop can also contain logic that is more sophisticated. In this example, we publish the outcome of a quick calculation using the iterator variable's value.
I believe that number 4 belongs in range (4):

Describe function.
A function is a segment of clean, reusable code that executes a single, connected operation. A higher level of code reuse and improved application modularity are provided via functions. Multiple aspects like printf() and main have already been shown to you (). These are referred to as built-in functions that the language itself offers, but we can also create our own functions, in the C programming language.

a study examined the average pay for men and women entering the workforce as doctors for 21 different positions.26 (a) if each gender was equally paid, then we would expect about half of those positions to have men paid more than women and women would be paid more than men in the other half of positions. write appropriate hypotheses to test this scenario. (b) men were, on average, paid more in 19 of those 21 positions. supposing these 21 positions represent a simple random sample, complete a hypothesis test using your hypotheses from part (a).
a) The hypothesis test is given as follows:
Null hypothesis: [tex]H_0: p = 0.5[/tex].Alternative hypothesis: [tex]H_1: p \neq 0.5[/tex]b) There is sufficient evidence to conclude that each gender is not equally paid.
What are the hypothesis tested?At the null hypothesis, it is tested if there isn't enough evidence to conclude that men and women are not equally paid, that is, the proportion is of 0.5, hence:
[tex]H_0: p = 0.5[/tex].
At the alternative hypothesis, it is tested if there is enough evidence to conclude that men and women are not equally paid, that is, the proportion is not of 0.5, hence:
[tex]H_1: p \neq 0.5[/tex].
We have a two-tailed test, as we are testing if the proportion is different of a value, with a standard significance level of 0.05, hence the critical value is of:
|z| = 1.96.
What is the test statistic?The test statistic is obtained by the equation presented as follows:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which the parameters of the equation are listed as follows:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.The values of these parameters are given as follows:
[tex]n = 21, \overline{p} = \frac{19}{21} = 0.9048, p = 0.5[/tex]
Hence the test statistic is of:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.9048 - 0.5}{\sqrt{\frac{0.5(0.5)}{21}}}[/tex]
z = 3.71.
There is sufficient evidence to conclude that each gender is not equally paid, as the test statistic is greater than the critical value for the two-tailed test.

The best method for analyzing network performance is to perform a baseline check on performance.
A system called an intrusion detection system (IDS) watches network traffic for unusual activity and issues notifications when it is seen.
While an IDS's major duties are anomaly detection and reporting, certain intrusion detection systems are also equipped to respond to suspicious activity or abnormal traffic by blocking traffic coming from suspect Internet Protocol (IP) addresses.
An intrusion prevention system (IPS), in contrast to an IDS, monitors network packets for potentially harmful network traffic. However, unlike an IDS, an IPS's main objective is to prevent threats after they have been identified.
