Answer:
Time plot.
Explanation:
A time plot, also known as a time series can be defined as a graphical representation of a pre-defined value (data) against time.
If we recorded the average U.S. Housing Price every month for the next year, the graphical display which is most appropriate to display the data is a time plot.
Generally, when representing data that changes with respect to time or that are random in nature; a time plot is considered to be the most effective graphical display to use.
In this scenario, the average U.S. Housing Price that is observed should be plotted against the time of occurrence (months) over a year.
Answer:
The correct answer is option (D) Identify the impact on safety of the property
Explanation:
Solution
In every Business Impact Analysis, the first and the most important step is for the CISO is to identify and estimate the impact of the aftereffects on the business and property of an organization that may be occurred from the disaster.
Physical security is very important, but it is not noticed by most organizations. It is important if you do not want anyone to take away your information or destroy it, in case of natural calamity. the reason could be that, the intruder is doing it for his personal achievement, financial gain,or seeking revenge or when one is taken unaware and becomes a target. If this security is not maintained properly all the safety measures will not be useful once the attacker gets through by gaining physical access.
Example of property can be software, equipment, facilities, company’s assets.
Answer:
Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
- Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
- External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
- Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.
<u>Answer:</u>
<em> </em><em>Modem is an hybrid device,</em><em> which is responsible for modulating and demodulating information. </em><em>It is a transmission medium and also it is a hardware tool used for connecting to internet.</em>
<u>Explanation:</u>
What is modulation?, let us understand. The <em>process of converting analog to digital signal is called modulation and demodulation is vice-versa.</em> The computer connects internet classically using telephone wire.
The <em>telephone wire understands only analog signal and a computer understands only digital signal.</em> So Modem’s role is to take care of this aspect while <em>connecting to the internet.</em>
