When you write HTML code, you use tags to describe the structure of information on a webpage. These tags are represented by the following symbols <>. All of HTML is written using different types of tags such as <body>, <main>, <div>, <nav>, etc. Each of these serves a different purpose but are all used for structuring the specific information on a website so that the information is well organized and is not all on top of each other. This also allows for specific sections to be easily targeted and styles separately from the other sections.

The steps are:
Reconnaissance: This is when hacking begins.Three different kinds of scanning are involved.Gaining Access: During this stage, an attacker enters the system or network using a variety of tools or techniques. Keeping Access Open Clearing the Way:Changing the subject: How do hackers obtain information?One method is to use spyware, which sends data from your device to others without your knowledge or consent, to try and obtain data directly from an Internet-connected device. By tricking you into opening spam email or into "clicking" on attachments, images, and links in it, hackers may be able to infect your computer with spyware.
Note that Hackers may write programs that look for unprotected entry points into computers and network systems. By infecting a computer or system with a Trojan horse—a tool designed by hackers to steal sensitive data secretly from a victim—hackers can gain backdoor access.

John Doe, the Netcare Hospital's IT director, is in charge of network management. He has asked
for your assistance in developing a network solution that will meet the needs of the hospital. The
hospital is expanding, and the management of the hospital has made funds available for network
upgrades. The medical staff would like to be able to access medical systems from any of the
patient rooms using laptop computers. Access to patient medical records, x-rays, prescriptions,
and recent patient information should be available to doctors and nurses. John purchased new
servers for the data center and installed them. The wireless LAN (WLAN) has about 30 laptops,
with another 15 due in six months. The servers must be highly available. The hospital's patient
rooms are located on floors 6 through 10. Doctors should be able to roam and connect to the
network from any floor.
According to a radio-frequency report, a single access point located in each communication closet
can reach all of the rooms on each floor. The current network is comprised of ten segments that
connect to a single router that also serves the Internet. Routing Information Protocol Version 1
is used by the router (RIPv1). The new back-end servers are housed in the same segment as those
on floor 1. John mentions that users have complained about slow server access, he would like to see a proposal for upgrading the network with faster switches and providing faster access to the
servers. The proposal should also include secure WLAN access on floors 6–10. Include an IP
addressing scheme that reduces the hospital's reliance on Class C networks. He wishes to reduce
the number of Internet service provider-leased networks (ISP).

1. Mean : A group of numbers added together divided by the total number of numbers in the
group
2. Mode : Among a set of numbers, the one that pops up most frequently.
3. Median : The intermediate number among several numbers (half the numbers in the group are higher than the median and half the numbers in the group are lower than the median
4. Minimum : The lowest value in a group of values, eliminating any outliers, is known as the statistical minimum, or h.
5. Maximum: The highest value in a group of values, eliminating any outliers, is known as the statistical maximum, or h.
6. Range: The difference between the greatest and smallest values in a collection of data—the range is calculated by deducting the sample maximum and minimum.
8. Quartile: Three values called quartiles divide sorted data into four equal portions with the same amount of observations in each.
14. T-test : The t-statistic in statistics measures how far an estimated value of a parameter deviates from its hypothesised value in relation to its standard error.
9. Inter-quartile range: The spread of the data is measured statistically by the interquartile range (IQR).
15. Analysis of variance: To examine the variations in means, analysis of variance is a group of statistical models and the corresponding estimation techniques.
10. Variance : The variance is the mean squared difference between each data point and the distribution's mean as determined by each data point.
16. Regression : Regression analysis is a statistical method for connecting a dependent variable to one or more independent (explanatory) variables. A regression model can demonstrate whether variations in the dependent variable are related to variations in one or more explanatory variables.
11. Standard deviation : The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.
12. Standard error : The population mean and sample mean are likely to deviate from one another, and the standard error of the mean, or simply standard error, shows how likely this is.
7. Confidence level : Another term for probability in statistics is confidence.
13. Confidence interval: If you repeat your experiment or resample the population in the same manner, the confidence interval is the range of values you expect your estimate to fall within a specific proportion of the time.
Therefore, mean, mode, median, minimum, maximum, range, quartile, t-test, inter-quartile, Analysis of variance, variance, regression, standard deviation, standard error, confidence level, confidence interval are some functions of statistics.

And office now has a total of 35 employees 11 were added last year the year prior there was a 500% increase in staff how many staff members were in the office before the increase
Answers
There were 5 staff members in the office before the increase.
To find the number of staff members in the office before the increase, we can work backward from the given information.
Let's start with the current total of 35 employees. It is stated that 11 employees were added last year.
Therefore, if we subtract 11 from the current total, we can determine the number of employees before the addition: 35 - 11 = 24.
Moving on to the information about the year prior, it states that there was a 500% increase in staff.
To calculate this, we need to find the original number of employees and then determine what 500% of that number is.
Let's assume the original number of employees before the increase was x.
If we had a 500% increase, it means the number of employees multiplied by 5. So, we can write the equation:
5 * x = 24
Dividing both sides of the equation by 5, we find:
x = 24 / 5 = 4.8
However, the number of employees cannot be a fraction or a decimal, so we round it to the nearest whole number.
Thus, before the increase, there were 5 employees in the office.

Arrays of structures ________. Group of answer choices None of the above. are automatically passed by reference cannot be passed by reference are automatically passed by value
Answers
Answer:
are automatically passed by reference.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
This ultimately implies that, parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.
This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.
A character positions in arrays start counting with the number 0 not 1.
Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
Generally, arrays of structures are automatically passed by reference through the use of a REPLICATE function.
