Answer:
The "Creeper system," the first computer virus, was an experimental self-replicating virus released in 1971. It was filling up the hard disk to the point that a computer could no longer function. BBN technology in the United States produced this virus. When the Creeper virus infects a computer, it causes it to output a file. It will then cease to function while it searches for another TENEX system. It creates a connection with the machine in question, and so on. Its last payload or impact when it's finished with a system is to display its message.

Answer:
"2009" and clicking "does not equal 2009"
Explanation:
The operator, 'does not equal', is a filtering operator used to exclude a specified attribute. The 'does not equal' operator is also used to provide the definition of the condition of the filter given that there are different values of two attributes
Therefore, given that there are only four years, and Greg needs the information of the last three years, which are, 2010, 2011, and 2012, the information for the year 2009 is to be excluded
Therefore, the correct option is; "2009" and clicking "does not equal 2009"

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).

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.

The wiring and connectors that carry the power to a motor must be in good condition. When a connection becomes loose, oxidation of the copper wire occurs. The oxidation ____. A. acts as an electrical resistance and causes the connection to heat more B. has no effect on the electrical connection C. decreases the resistance D. none of the above
Answer: A. acts as an electrical resistance and causes the connection to heat more.
Explanation:
The wiring and connectors that carry the power to a motor must be in good condition. It should be noted that in a case whereby the connection becomes loose, then the oxidation of the copper wire occurs and thee oxidation will act as an electrical resistance and then results in the connection to heat more.
In such case, this has an effect on the electrical connection and increases the resistance. Therefore, the correct option is A.

Why are programming languages like Java and Python ideal for rapid development?
Because Java, as well as Python, are high-level programs that don't need generating or parsing, they are perfect for quick development. This implies that engineers can code a program without testing it first and then publishing it.
What are programming languages?A method of nomenclature for creating software applications is known as a computer program. The majority of formal programming are text-based, though they can also be graphical.
A substantial rise in the use of Python for machine learning and data analysis supports its status as the programming with the biggest growth. Python is a programming language with dynamic typing, while Java is a structured query and compiler language. Java is faster at play and simpler to debug thanks to this one difference, while Python is simpler to utilize and read.

The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the average of those numbers, and displays the numbers and their average to the user.
The program uses methods to:
1) get the numbers entered by the user all on one line separated by spaces;
2) calculate the average of the numbers entered by the user; and
3) print the results.
The first method should take no arguments and return a String of numbers separated by spaces.
The second method should take a String as its only argument and return a double (the average).
The third method should take a String and a double as arguments but have no return value.
