Your organization uses the following tape rotation strategy for its backup tapes: The first set of tapes is used for daily backups. At the end of each week, the latest daily backup tape is promoted to the weekly backup tape. At the end of each month, one of the weekly backup tapes is promoted to the monthly backup tape. What kind of backup tape rotation strategy is being used
Answer:
- Grandfather
Explanation:
In the given scenario, the 'grandfather backup rotation strategy' is employed to have the backup of the audiotape files. This is because the entire process is segregated into three distinct sections; daily backup that keeps the track of all the files recorded every day. It is followed by weekly storage of the audio files after the week wraps up in order to save it for future usage. Lastly, 'monthly' media is backed up in order to ensure that no data is left to be backed up that might be required later. This promotes a quicker, easier, yet complete strategy for backing up the desired data files in the systems. Hence, 'grandfather-son-rotation strategy' is the correct answer.

Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Data administration is a strategic process that is typically responsible for establishing information policy, data planning, data dictionary development, and monitoring data usage in the firm.
4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,
Answer:
[tex]\sigma_x = 5.68[/tex]
Explanation:
Given
[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]
Required
The standard deviation
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]
[tex]\bar x = \frac{64}{8}[/tex]
[tex]\bar x = 8[/tex]
The standard deviation is:
[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
So, we have:
[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]
[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]
[tex]\sigma_x = \sqrt{32.2857}[/tex]
[tex]\sigma_x = 5.68[/tex]

Answer:
A mouse.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, scanner, projector, mouse, etc.
A mouse is an input device that is designed and used to select specific menu options, drag and drop options and to draw something on screen.

Which statement describes how to insert the IF, COUNTIF, or SUM function into a cell?
Use the Insert tab and select the appropriate function from the Functions group.
Type an = sign in the cell, followed by the name of the function and the relevant arguments.
Right-click the cell to access the context menu to insert the function.
Use the View tab and choose the correct function from the displayed list.
Answer:
Type an = sign in the cell, followed by the name of the function and the relevant arguments.
Explanation:
Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents. There are different types of functions used in Microsoft Excel to perform specific tasks and these includes;
1. VLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized vertically. Thus, it's typically used for searching values in a column.
2. SUMIF function: it is an Excel function to sum cells that meet criteria such as text, dates and numbers. This function can be used with the following logical operators; <, >, and =.
3. COUNT function: it's an Excel function to find the total number of entries in a column. For example, to count the number of entries in B1:B15; COUNT(B2:B15).
4. IF function: runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to fail scores that are below 40; IF (A1 < 40, "Fail", "Pass").
5. HLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized horizontally. Thus, it's typically used for searching values in a column.
In Microsoft Excel, to insert the IF, COUNTIF, or SUM function into a cell, you should type an equal to (=) sign in the cell, followed by the name of the particular function and the relevant arguments.
For example, to use the SUMIF function, you should type; =SUMIF(A2:B5, "Peter", C1:C9).
why the internet is not policed
Answer:
The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work

An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions
"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.
Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.
⇒ There are two kinds of Buffer overflow attacks such as:
Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.Thus we can say that the correct answer is a Buffer overflow.

why is computer virus called destructive program
Answer:
A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.
Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.
Explanation:
The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.
