Computers work on the garbage-in, garbage-out concept. Comment

Answers

Answer 1
Stands for "Garbage In, Garbage Out." GIGO is a computer science acronym that implies bad input will result in bad output.

Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage." For example, if a program asks for an integer and you enter a string, you may get an unexpected result. Similarly, if you try to open a binary file in a text editor, it may display unreadable content.

GIGO is a universal computer science concept, but it only applies to programs that process invalid data. Good programming practice dictates that functions should check for valid input before processing it. A well-written program will avoid producing garbage by not accepting it in the first place. Requiring valid input also helps programs avoid errors that can cause crashes and other erratic behavior.

NOTE: Because the related terms FIFO and LIFO are pronounced with a long "i," GIGO is typically pronounced "guy-go" (not gih-go). This also helps avoid confusion with the prefix "giga," which is pronounced with a soft "i."

why the internet is not policed​

Answers

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

Abdullah wants to send sessitive data. Abdullah wants to make sure that only ahmed can see and read this. How can abdullah protect this data, so that ahmed can only access it. By using this information make an algorithm.

Answers

Answer:

Use an encryption algorithm

Explanation:

An encryption algorithm can be used to hide the message from parties in-between or any third parties that might want to intercept the message being sent by Abudullah to Ahmed.

Encryption algorithms use cryptographic methods to encrypt or code data such that only the sender and receiver of that data have the keys to properly decode/decrypt these messages/data.

A logistics company's vulnerability scan identifies the following vulnerabilities on Internet-facing devices in

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

Answers

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.

Write a program to input the TotalCost and display the Assured gift as per the following criteria TotalCost(TC) Assured Gift Less than or up to 2000 Wall Clock 32001 to 5000 School Bag 5001 to 10,000 Electric Iron More than 10,000 Wrist Watch​

Answers

Answer:

The program in Python is as follows:

TotalCost = int(input("Total cost: "))

if TotalCost <= 2000:

   print("Wall Clock")

elif TotalCost >= 2001 and TotalCost <= 5000:

   print("School Bag")

elif TotalCost >= 5001 and TotalCost <= 10000:

   print("Electric Iron")

else:

   print("Wrist Watch")

Explanation:

This gets input for total cost

TotalCost = int(input("Total cost: "))

If the total cost is up to 2000, print wall clock as the assured gift

if TotalCost <= 2000:

   print("Wall Clock")

If the total cost is between 2001 and 5000 (inclusive), print school bag as the assured gift

elif TotalCost >= 2001 and TotalCost <= 5000:

   print("School Bag")

If the total cost is between 5001 and 10000 (inclusive), print electric iron as the assured gift

elif TotalCost >= 5001 and TotalCost <= 10000:

   print("Electric Iron")

If the total cost is more than 10000, print wrist watch as the assured gift

else:

   print("Wrist Watch")

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

Answers

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.

Mary uploaded some images on her website. She chose an image and downloaded it. She found that the image she saw on screen did not seem to have the same DPI as when she had scanned it (she had uploaded a scanned image with 300 DPI). What could be reason with this visual decrease in DPI on the computer screen? (Correct Answer only)

A. Some image resolution was lost while uploading it
B. She downloaded a compressed version of the image.
C. The computer reset the resolution of the image.
D. Her file was probably corrupted while downloading.
E. Computer screens typically display images of only 72 DPI.

Answers

It could be A or B, with a guess that it’s A. Many websites require images to be compressed on uploading so that it takes less of the site’s database storage, but the wording leads me to believe it may be B. Any thoughts?

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.

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

Answers

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.
