Answer:
Hackers frequently spend long hours examining the types and structures of targeted systems because they must use guile, or fraud to bypass the controls placed on information owned by someone else.
Explanation
The perception of a hacker has evolved over the years.
The traditional hacker profile was a male, aged 14 to 18.76% of hackers are men whose ages are between 14 years (8%) to 50 (11%). The average age is 35 years (43%).A hacker is persevering, patient, creative, bright and having a passion for what he does.Hackers today can be expert or novices.The experts create the software and schemes to attack computer systems.While the novices merely use software created by the experts.Hackers used to be viewed as people who would sit in a place and try to remotely gain access to a computer. This perception has changed because, hackers can work with people in an organization, suppliers, or may even write a program to do the hacking.
Who is a Hacker?This is an individual or an organization who is very proficient with the use of the computer and who can use these skills to breach the cyber security of other individuals or organizations.
When a hacker does this to check the limitations and weaknesses of a cyber network so that it can be improved, it is called Ethical Hacking.

A new laptop was delivered to your home and left on the porch while you were at work. It is very cold outside, and you don't know how long it has been there. You unpack the computer and would like to know if it is working properly.
What should you do?
Answer:
Let the computer warm up to room temperature before turning it on.
Explanation:
The laptop has been shipped to the user's home when he were at work and found on the deck. Outside it is really cool and he don't remember how long it has been there. Then, the user open his laptop and want to know whether it is functioning properly. Instead, let the machine warm up while switching it on to room temperature.
When a computer is still in a cold climate, they have to let it heat up to room temperature apx. 6-24 hours before switching it on. Otherwise, its heat the elements generate could cause water moisture within the laptop. That water could then harm elements of the system.
Assume there is a variable , h already associated with a positive integer value. Write the code necessary to count the number of perfect squares whose value is less than h , starting with 1 . (A perfect square is an integer like 9 , 16 , 25 , 36 that is equal to the square of another integer (in this case 3*3 , 4*4 , 5*5 , 6*6 respectively).) Assign the sum you compute to a variable q For example, if h is 19 , you would assign 4 to q because there are perfect squares (starting with 1 ) that are less than h are: 1 , 4 , 9 , 16 .

Answer:
Option(d) i.e "storing a float in an int" is the correct answer for the given question.
Explanation:
Typecast is used for the changing the one datatype to the another datatype Their are two types of casting1 implicit
In this typecast we change the smaller datatype into the larger datatype.
For example
int to float
2 Explicit
In this typecast we change the larger datatype into the smaller datatype in an explicit manner.
For example
float to int.
in the given question we required the casting in the option(d) i.e "storing float in an int" That's why this option is correct and all other options are incorrect.Final answer:
A cast is required when storing a float in an int because this is a narrowing conversion that could lead to loss of information. Other provided options involve either automatic promotions or operations that already result in the correct type.
Explanation:
A cast is required in which of the following situations?
Using charAt to take an element of a String and store it in a char does not require a cast because the charAt method returns a char type.
Storing an int in a float does not require a cast because an int can be promoted to a float without loss of precision.
Storing a float in a double does not require a cast because a float can be automatically promoted to a double which has a larger range.
Storing a float in an int does require a cast because a float has fractional parts and an int does not, so this is a narrowing conversion with potential loss of information.
Therefore, the correct answer is 'd. storing a float in an int' requires a cast.
Which is true about POP3 and IMAP for incoming email?
Both keep email on an email server by default
IMAP keeps email on an email server by default
Neither keep email on an email server by default
POP3 keeps email on an email server by default.
Answer:
IMAP keeps email on an email server by default
Explanation:
IMAP and POP3 both are email receiving protocols. These protocols used to access the emails from the email server to client inbox.
In POP3 (Post Office Protocol 3) emails are received in the user inbox. This protocol removes the emails from email servers and keep in user inbox.
While in IMAP (Internet Message Access Protocol) the message is directly access form the email server, it will not stored on the local user device.
So, the IMAP is the only protocol in which email are kept saved on email serve by default.
Tier I (core) capital includes at least some part of which of the following? I. Common stockholders' equity II. Retained earnings III. Subordinated debt IV. Allowance for loan and lease losses
Answer:
I and II only
Explanation:
Tier 1 capital is the core measure of a bank's financial strength from a regulator's point of view. It is composed of core capital, which consists primarily of common stock and disclosed reserves (or retained earnings) —that appears on the bank's financial statements, but may also include non-redeemable non-cumulative preferred stock.
Tier 1 capital is the assets the bank holds in its reserves in order to keep it functioning through all the risky transactions it performs, such as trading/investing and lending. Tier 1 capital includes common stock, retained earnings, and preferred stock.
Thus, Tier I (core) capital includes common stockholders' equity and retained earnings among the options.
Answer:
I. Common stockholders' equity II. Retained earnings
Explanation:
Tier 1 capital is a primary indicator of the financial power of a bank from authority's perspective. It is comprised of main assets, consisting primarily of common shares and declared assets, but can also contain un-redeemable un-cumulative preferred shares.
The core parts of equity capital are identified as the tier 1 capital: bonds, non-disposable balance sheets and retained income of shareholders, earned through the bank's lifetime. This reflects the capital sum which enables a bank to bear deficits without impacting depositors ' interest.

Which of the following additional networking services uses common protocols like RIPv2 and STP to allow network devices to effectively communicate with each other or with other networks? a. Telephony b. Time synchronization c. Subscription d. Routing and switching
Answer:
D. Routing and Switching
Explanation:
The purpose of a network is to connect computers and peripherals using switches and routers. These two let the devices connected to your network communicate with each other as well as talk to other networks.
Routers are used to tie multiple networks together. For example, you would use a router to connect your networked computers to the Internet and thereby share an Internet connection among many users. The router will act as a dispatcher, choosing the best route for your information to travel so that you receive it quickly.
Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other. Through information sharing and resource allocation, switches save you money and increase productivity.

1. What are multiuser systems? Why are they successful? 2. What is the Free Software Foundation/GNU? What is Linux? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? 3. What is a shell? How does it work with the kernel and with the user?
Answer:
Explanation:
1)A multi user system is a computer operating system which allows multiple users to access the single system the single system with one operating system on it.it is generally used on large mainframe computer.
They are successful because of the powerful, efficient, stable and secure operating systems like LINUX. it has a capability of providing each user the same data ensuring total privacy from each user even while accessed by 100's of users simultaneously.
2)“Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. GNU is an operating system which is 100% free software. It was launched in 1983 by Richard Stallman (rms) and has been developed by many people working together for the sake of freedom of all software users to control their computing. Technically, GNU is generally like Unix. But unlike Unix, GNU gives its users freedom.
Linux is the best known and most used open source operating system,it is the software that sits underneath all of the other software on a computer,it receives request from those pros and relay these request to the computer hardware.
Linux systems tend to fall into several classes, each of which draw from a different set of components.
Each kind of system includes the Linux kernel and the tools necessary to support at least one Linux file system. Each kind of system includes other run time libraries, utilities and applications. The run time support and applications can be general purpose or they can be tailored to the system’s use.
1)Desktop systems are probably what most people think of when they answer this question. They are normally based on distributions and there are hundreds of distributions. It is normally possible to tailor a distribution but typically they have
a)POSIX compliant shared libraries and commands, often from the Free Software Foundation
b)A Windowing system, commonly X Windows, which is most often from X.Org
c)A Window manager system such as Gnome or KDE
d)A tailored set of applications depending on the user’s need. Development tools such as compilers and header files are included in developer distributions but not in others, for example.
2)Server systems are desktop systems from which the windowing system and window manager are typically removed, but otherwise are often from the same distributions as desktops, only configured differently at install time.
3)Purpose built embedded systems use something like Busy box rather than the FSF GNU tools, often omit the windowing system and window manager and often have very limited sets of utilities and applications. Routers often fall in this category
4)Custom run time systems are designed to replace the POSIX compliant run time system with one that is purpose built. They tend to have custom GUIS and are designed so that the user doesn’t normally access the system management tools. Roku’s streaming box and Android are well known examples.
3) A shell is a software interface that's often a command line interface that enables the user to interact with the computer. Some examples of shells are MS-DOS Shell (command.com), csh, ksh, PowerShell, sh, and tcsh.
It works with the kernel and the user by allowing the user to interface with the kernel from the command line.
Multiuser systems allow concurrent access by multiple users, and find success from maximizing resource utilization and promoting collaboration. The Free Software Foundation/GNU promotes freedom in computing and established the GNU operating system, while Linux is the kernel of the system. A shell interacts with the kernel to execute commands and relay results to the user.
Explanation:Multiuser systems are computing environments in which multiple users can access the system concurrently or at different times, often through networked terminals. They became successful because they maximize resource utilization and promote collaboration among users.
The Free Software Foundation/GNU is an organization that promotes freedom in computing by promoting and defending the rights to use, study, copy, modify, and redistribute software. This organization established the GNU operating system, which is a collection of free software. Linux is a free and open-source Unix-like operating system, which Torvalds initiated, with vast open-source community contributions. Linux is essentially the kernel, the core part of the operating system that interacts directly with the hardware. The remainder of the operating system, aside from Linux, primarily comes from the GNU project, including the GNU system utilities and the GNU Shell.
A shell is a software interface that allows users to interact with the operating system. The kernel, on the other hand, is the core of an operating system, managing the system's resources and the communication between hardware and software components. The shell communicates with the kernel to execute commands and present the result to the user.

Is it necessary that every autonomous system use the same intra-AS routing algorithm? Why or why not?
Answer:
NOT
Explanation:
Intra-AS refers to an internal autonomous system in which routing is internal to the autonomous system alone but completely invisible to those outside of it. That being said it is NOT necessary for every autonomous system to use the same intra-AS routing algorithm, because each one has administrative autonomy for routing within any autonomous system.
Final answer:
No, it is not necessary for each autonomous system to use the same intra-AS routing algorithm because each AS has different needs and requirements based on its network topology, traffic patterns, and policies.
Explanation:
It is not necessary that every autonomous system (AS) use the same intra-AS routing algorithm. autonomous systems are large networks or group of networks under a common administration that present a common routing policy to the internet. Each AS is free to choose the routing algorithm that best meets its own needs and policy requirements. For example, one AS may prioritize routing speed and efficiency, while another prioritizes security or cost-effectiveness.
Using the same intra-AS routing algorithm across different autonomous systems is not mandatory because each AS has different network topologies, traffic patterns, and policies. Optimal routing within an autonomous system depends on these factors, and therefore, the autonomy in selecting an intra-AS routing protocol is crucial. Common intra-AS routing protocols include RIP, OSPF, and IS-IS.
When you ran the Chkdsk command in this lab, it had to run during the startup process. Why was this necessary? What form of the Chkdsk command can you use in a command prompt window that does not require a restart to run?
Answer:
Because it has to check the disk that Windows is installed on.
Explanation:
The chkdsk program needs to check all structures on the disk, including ones the Operating System would be using if it was running on that disk. Therefore to check the disk that Windows is installed on chkdsk must run before Windows is started, so that those structures are not in use.

A mobile device user has tried to install a new app numerous times without success. She hasclosed all unused apps, disabled live wallpapers, and restarted the device in an attempt to getthe app to install. Which of the following steps should the user take next?1. Back up all user data and perform a factory reset.2. Check for sufficient available storage space. 3. The user needs to check to verify there is enough free storagespace to install the app. If not, unused apps can be uninstalled, and anapp to clean up space can be utilized.4. Disable full device encryption.5. Generate a new public key
Answer:
2. Check for sufficient available storage space.
Explanation:
Without sufficient storage space, no new installation or updating of previous application can occur because there is no space to house the new data. If there is lack of space after checking it's best to delete unwanted data to free up some space.
The next step for the user is to check for sufficient available storage space and free up space if necessary by uninstalling unused apps or using a cleanup app.
Explanation:If a mobile device user has tried several measures to install a new app without success, the next step she should take is to check for sufficient available storage space on the device. This involves ensuring that the device has enough free space to accommodate the new app. If there isn't enough space, the user can uninstall unused apps or use a dedicated app to help clean up and free up storage space. A factory reset should be a last resort as it will erase all data on the device. Disabling full device encryption and generating a new public key are not related to app installation issues and would not resolve the problem.

Answer: weak passwords are a problem
Explanation: one of the reason it becomes a problem is due to the fact that it gives access to hackers to infiltrate your information. So it is better to use a strong password.
Weak passwords are not solely the responsibility of IT. Individuals must take the initiative to create strong passwords. IT can provide guidelines and tools, but employees must make the right choices.
Explanation:In order to explain why weak passwords do not originate with IT, it is important to highlight that it is the responsibility of individual employees to create strong passwords. IT can provide guidelines and tools to help employees create strong passwords, but ultimately it is up to each individual to follow these guidelines. Weak passwords can originate from various factors such as lack of awareness about the importance of strong passwords, laziness, and human error. IT can implement measures like password complexity requirements and regular password updates, but they cannot control the choices made by employees.
For example, IT may provide a password policy that requires passwords to be a minimum of 8 characters long, include a combination of uppercase and lowercase letters, numbers, and special characters. However, if employees choose to use simple and easily guessable passwords like 'password123', '123456', or their own name, it undermines the efforts of IT to secure the organization's systems and data.
Ultimately, it is crucial to emphasize that strong password practices are a collective responsibility within the organization, and IT can play a supportive role by educating employees, implementing security measures, and enforcing policy compliance.

When we consider data quality, what are the differences among validity, reliability, and representativeness? How can you know the data have high levels of these characteristics?
Answer:
Validity is the degree to which the research measures what it has to measure. High validity = Proper Research Design.
Reliability is the measure to which research measurement techniques are free of error or mistakes. High realiability = Reasearchers know the sample fully understands the question asked.
Representativeness is the extent to which consumers in a study are similar to the larger group of interest. High representativeness = Sample is large and chosen in an unbiased way.
Final answer:
Validity, reliability, and representativeness are elements of data quality, referring to the accuracy of measurement, consistency of results, and degree to which a sample reflects the population, respectively. High levels are assessed by examining the data collection process, statistical relevance, and the representativeness of the sample. Investigators ensure these characteristics by careful design and rigorous testing of data collection methods.
Explanation:
When discussing data quality, it is important to differentiate between validity, reliability, and representativeness. Validity refers to how well the data measure what they are intended to measure. In other words, it is about the accuracy and appropriateness of inferences drawn from the data. Reliability, on the other hand, is about the consistency of a measure. A reliable dataset will yield similar results under consistent conditions or when repeated measurements are made. Lastly, representativeness pertains to the degree to which a sample mirrors the population from which it was drawn. It is critical to ensure that the findings from a dataset can be generalized to a broader context.
To ensure high levels of validity, one may look at the epistemological status of the data, considering how well the data corresponds to real-world phenomena. Ensuring high levels of reliability may involve examining types of reliability such as inter-rater reliability, internal consistency, and test-retest reliability. As for representativeness, researchers must consider who has been sampled, how they were sampled, and the purpose of the sampling.
Researchers and observers can ascertain these quality levels by questioning who collected the data, how and when it was collected, whether the data have been accurately classified, what the data resolution is, and their statistical relevance. Addressing these points helps in determining the credibility and trustworthiness of the data, which align with concepts of credibility, dependability, and confirmability in qualitative research.
