Question 9

What type of memory contains the instructions needed to start a computer?

Accepted Answer

ROM (or Read-Only Memory) chips are non-volatile memory devices that store permanent instructions needed to start a computer or other electronic devices. These instructions are known as firmware and cannot be modified or deleted by the user. On the other hand, RAM (Random Access Memory) modules are volatile memory devices that store temporary data and programs that can be modified or deleted by the user. Virtual memory is a technique that allows a computer to use part of its hard disk as an extension of its RAM, while Flash memory is a type of non-volatile memory that can be electrically erased and reprogrammed.

Question 10

Rory is shopping for a computer to create and edit video content.What type of computer would best suit her needs?

Accepted Answer

For creating and editing video content, a powerful processor and a large monitor are crucial. A desktop computer would offer the best performance and screen size for such tasks. A laptop with a lower-end processor may not be able to handle the processing requirements, and a touchscreen or a mid-sized hard drive may not be as important as having a strong processor and monitor. A tablet would not be sufficient for running complex video editing software.

Question 11

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?

Accepted Answer

An external hard drive is the best option for Riley because it will provide additional storage space that he can access without the need for an internet connection. It can be easily connected to his laptop through a USB or other external port, and he can transfer files and data to and from the external hard drive as needed. While cloud storage and optical hard drives may also be options, cloud storage requires internet access and optical drives are becoming less common and offer limited storage capacity. An internal hard drive would require opening up the laptop and is generally more difficult to install compared to using an external hard drive. Therefore, D is the best choice.

Question 12

When you save a file to the cloud, where is it stored?

Accepted Answer

When you save a file to the cloud, it is stored on a remote server. The server can be located in various locations around the world, but the important thing to note is that it is not stored locally on a flash drive, internal storage, or external storage device.

Accepted Answer

Checking benchmarking information online will allow Ariel to compare the performance potential of each laptop based on objective data and tests. This is likely to be more reliable and accurate than asking the manufacturers or relying on the opinions of a salesperson. Buying all three and returning two is not a practical solution, and may not be allowed by the retailer's return policy.

Question 15

When a printer is not working even after being plugged in, the first thing to check is whether the correct device driver is installed on the computer. If the correct driver is not installed, the computer will not be able to communicate properly with the printer, causing it to not print. Checking the connection to the Internet is irrelevant in this scenario.
