The reason for this visual decrease in DPI on the computer screen is some image resolution was lost while uploading it. The correct option is A.
What is resolution?Resolution is the quality of the image that we see in the screen. It is the number of pixels per inch of space. The meaning of PPI is pixel per inch. When a high-resolution picture is seen, it means there are more pixels per inch.
When a picture is downloaded from a site. It does not download in the original pixels because during downloading some pixels are lost due to slow net or the settings of the computer. And a compressed version does not download on its own, and corrupted files do not affect the resolution.
Thus, the correct option is A. Some image resolution was lost while uploading it.

A logistics company's vulnerability scan identifies the following vulnerabilities on Internet-facing devices in
the DMZ: SQL injection on an infrequently used web server that provides files to vendors SSL/TLS not used for a website that contains promotional information
The scan also shows the following vulnerabilities on internal resources: Microsoft Office Remote Code Execution on test server for a human resources system
TLS downgrade vulnerability on a server in a development network In order of risk, which of the following should be patched FIRST?
A. Microsoft Office Remote Code Execution
B. SQL injection
C. SSL/TLS not used
D. TLS downgrade
Answer:
A. Microsoft Office Remote Code Execution
Explanation:
From the given options, we have;
The web server having a SQL injection is infrequently use
The information on the website having SSL/TLS not used is promotional
The location of the server having a TLS downgrade is on a development network
The location of the Microsoft Office Remote Code Execution is on a human resource system test server
Therefore, given that the test server, is the deployment source of the main server, and that with a Remote Code Execution, RCE, cyber attack, the attacker is able to make commands work on other computers, the RCE attack on the test server is a potential access of an attack on the main servers, and should be patched first.
You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
Tristen is teaching her history course. She printed off her presentation so the students could take notes. Wyatt is
teaching a science course. He wants to make sure students who do not have PowerPoint can still view the
presentation. Reed is teaching a math course online. He finds the students are very visual and wants to control the
timing per slide
Which best describes how each teacher handled their presentations?
O Tristen created handouts, Wyatt saved as a PDF, and Reed saved as a video
O Tristen created a video, Wyatt saved as a PDF, and Reed broadcasted.
O Tristen created handouts, Wyatt saved as a video, and Reed saved as a PDF.
O Tristen created a video, Wyatt broadcasted, and Reed saved as a video
Since Tristen want her students to take notes on her presentations, she should have some sort of handout.
Because Wyatt, wants to ensure that students who do not have PowerPoint can still view his presentations, converting it into a pdf is best.
Since Reed's students are very visual, converting his slides into a video will make it better for students who want to spend some time assessing some of the graphs or equations.
Thus, A is the best choice.

how are the computer classified into different types
Answer:
Computers differ based on their data processing abilities. They are classified according to purpose, data handling and functionality. ... According to data handling, computers are analog, digital or hybrid. Analog computers work on the principle of measuring, in which the measurements obtained are translated into data.Programming languages create codes that represent binary numbers so that programmers can write in a language closer to natural speech.
Answer:
True
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
This ultimately implies that, programming languages are designed and developed for creating codes that represent binary numbers (0s and 1s), so that programmers or software developers can write in a language closer to natural speech i.e the human language.

You are concerned about attacks directed at your network firewall. You want to be able to identify and be notified of any attacks. In addition, you want the system to take immediate action to stop or prevent the attack, if possible. Which tool should you use
Answer:
Intrusion Prevention System (IPS)
Explanation:
Firewall can be defined as a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
Simply stated, a firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.
A firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access.
Basically, it is a network security device or security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer
Thus, the tool you should use is an intrusion prevention system (IPS).

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
