Question 2

Rory is shopping for a computer to create and edit video content. What type of computer would best suit her needs?
A) Desktop computer with large monitor and the best available processor
B) Laptop with a lower-end processor
C) Laptop with a touchscreen and mid-sized hard drive
D) Tablet that meets the requirements for running a productivity suite

Accepted Answer

For creating and editing video content, a desktop computer with a large monitor and the best available processor is the best option as it offers more power and a larger display for editing tasks. Laptops and tablets may not have the same processing power or screen size as a desktop, making it more difficult to edit videos efficiently.

C) He should enter Red-Cross.com because that is the name of the commercial company.
D) He should enter redcross.net because Red Cross is a network provider.

Accepted Answer

Nonprofit organizations typically use the .org domain, so Brendon should enter redcross.org instead of redcross.com.

Question 7

A friend of Muna's suggested a website that she can use to download music. How should she check if the website is secure?
A) A shield icon in the address bar
B) "https" as the protocol in the URL
C) the words "secure website" in the home page footer
D) ".com" or ".org" as the top-level domain of the website

Accepted Answer

The presence of "https" in the URL indicates that the website is secured with an SSL certificate, which ensures encrypted communication between the user's browser and the website's server. This is the most important factor to consider when checking the security of a website. A shield icon in the address bar is also a good indicator, as it signifies that the website is using HTTPS, but it may not be present on all browsers. The words "secure website" in the footer or the top-level domain of the website do not necessarily mean that the website is secure.

Question 8

Riley needs more storage space on his small laptop, and he needs that storage to be accessible without Internet access. What is the best storage option for Riley to add to his computer?
A) Cloud storage
B) Internal hard drive
C) Optical hard drive
D) External hard drive

Accepted Answer

An external hard drive would be the best option because it adds storage capacity without taking up space within the laptop. It is also easily portable, so Riley can take it with him wherever he goes. Additionally, the data on the external hard drive can be accessed without Internet access.

Question 9

Which computer component is primarily responsible for converting input (data) into meaningful output (information)?
A) Hard disk
B) CPU
C) Operating system
D) RAM

Accepted Answer

The CPU (central processing unit) is responsible for processing the input data and converting it into meaningful output or information. It is considered the brain of the computer and performs calculations, executes instructions, and manages the flow of data in and out of the computer. The other components listed (hard disk, operating system, and RAM) play important roles in the overall functioning of the computer, but they do not directly convert input into output.

Question 10

What type of memory contains the instructions needed to start a computer?
A) ROM chips
B) RAM modules
C) Virtual memory
D) Flash memory

Accepted Answer

ROM chips (Read-Only Memory) contain firmware that contains instructions needed to start a computer. This memory is non-volatile, meaning it retains its contents even when the computer is turned off.

Question 11

How many bits make a byte?
A) 4
B) 10
C) 16
D) 8

Question 12

When you start an app on your computer, the app's instructions are _____.
A) transferred from the hard drive to the RAM
B) transferred from the RAM to the hard drive
C) installed on the motherboard
D) updated on the ROM chip

Accepted Answer

When an app is started, its instructions are loaded from the hard drive into the computer's RAM (Random Access Memory) for faster processing. The RAM is a type of memory that the computer uses to temporarily store data and instructions that are currently in use. This allows the app to run more smoothly, without being bogged down by the slower speed of the hard drive.

Question 13

Joe wants to use an engaging image as a hook in his presentation, but he's afraid of violating any copyright laws. What should he do?
A) Search for an image on Yahoo
B) Search for an image on Creative Commons
C) Search for an image on Wolfram Alpha
D) Search for an image on Bing

Accepted Answer

Searching for an image on Creative Commons will provide Joe with images that have been specifically marked as available for reuse without violating copyright laws. It allows for filtering by license type, making it a safe and convenient option for finding images for presentations.

Question 14

Mateo is designing a technical diagram that many textbook publishers can use, and he wants to make sure he retains the rights to the diagram before selling it. At what stage does a copyright for his creative work come into effect?
A) As soon as he conceives the idea of the diagram
B) As soon as the image exists in physical form
C) As soon as someone wants to use it
D) As soon as he requests payment

Accepted Answer

Copyright protection begins as soon as a creative work is created in physical or tangible form, such as a drawing or written document. In this case, Mateo's technical diagram would be protected under copyright as soon as it exists in physical form. It is not dependent on whether someone wants to use it or if he requests payment. Therefore, option A is incorrect because the idea itself is not protected, option C is incorrect because protection does not stem from demand, and option D is incorrect because payment is not a factor in copyright protection.

Question 17

Which computer type will take up the most space in a workspace?
A) Desktop computer
B) Tablet
C) Laptop
D) All-in-one computer

Accepted Answer

A desktop computer typically takes up the most space in a workspace as it consists of a separate CPU, monitor, keyboard, and mouse. Tablets, laptops, and all-in-one computers have a more compact design and take up less space.

Question 18

News360 is a search engine because it gathers, organizes, and then distributes web content.

Accepted Answer

News360 is not a search engine. It is a news aggregator that uses AI to personalize news content for each user. The content gathered by News360 is already published on different websites, and News360 does not crawl the web to find new content.
