Question 1

Maya wants to connect three peripheral devices to her laptop , but has only one USB port.What is the best way to connect all the devices?

Accepted Answer

Using a USB hub is the best choice as it allows Maya to connect multiple devices to a single USB port. She can plug the hub into the USB port and then connect all three peripheral devices to the hub. This is a convenient and cost-effective solution. Converting a different kind of port to a USB port or using peripheral devices in the cloud may not be feasible or practical, and connecting one device at a time would be inconvenient and time-consuming.

Question 2

Eneida found an excellent deal on a printer and excitedly brought it home, plugged it in, and turned it on.Unfortunately, when she tried to print her homework for the next day, it didn't work.What should Eneida check to fix this problem?

Accepted Answer

The most likely cause of the issue is that the correct device driver (software that allows the computer to communicate with the printer) has not been installed on the computer. Eneida should check her computer's settings and ensure that the appropriate driver is properly installed. The other options (A, C, and D) are unlikely to be the issue causing the printer to not work.

Question 3

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

Accepted Answer

ROM (Read-Only Memory) chips contain the instructions, known as the BIOS (Basic Input/Output System), needed to start a computer. These instructions are permanently stored on the ROM chip and cannot be altered, which ensures that the computer can always boot up properly. RAM (Random Access Memory) modules, virtual memory, and flash memory do not contain the necessary instructions to start a computer.

Question 4

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

Accepted Answer

Creating and editing video content requires a computer with a powerful processor and dedicated graphics card. A desktop computer with a large monitor will provide the necessary processing power and screen real estate for video editing. Laptops may not have the same level of processing power, and a tablet would likely not have the necessary processing power or screen size for video editing.

Question 5

Nancy is about to give a presentation to her school's advisory board about some upcoming changes to their Nursing program.She wants to display the presentation from her laptop to the large screen in the conference room.What does she need to show the presentation?

Accepted Answer

Nancy needs a way to project the presentation from her laptop onto the large screen in the conference room. The best way to do this is with a projector that can display the image from her laptop onto the screen. A video camera, plotter, or monitor would not be suitable for this purpose.

Question 6

What kind of output does a 3-D printer create?

Accepted Answer

A 3-D printer creates a physical output by layering materials to create a three-dimensional object.

Question 7

What does 1 represent in stored data?

Accepted Answer

In binary data storage, a '1' typically represents the presence of an electronic charge, while a '0' would indicate its absence. This binary system is foundational to digital computing and data representation.

Question 8

Which of the following is not a computer form factor? omputer fo

Accepted Answer

Tabletop is not a recognized computer form factor. Tower, convertible tablet, and all-in-one are all established form factors in the computer industry.

Question 9

When you start an app on your computer, the app's instructions are _____.

Accepted Answer

When you start an app on your computer, the app's instructions are transferred from the hard drive to the RAM (Random Access Memory). This allows the processor to quickly access and execute the instructions, as RAM has much faster read/write speeds compared to the hard drive.

Question 10

Which of the following is a necessary step in maintaining computer hardware?

Accepted Answer

The answer of Which of the following is a necessary...

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 would provide the additional storage space Riley needs, and as it is not cloud storage, it can be accessed without Internet access. Additionally, an external hard drive is portable, so Riley can easily bring it with him if he needs to work on multiple computers.

Question 12

You've just signed a document for an insurance settlement, and you need to mail it back to the insurance company.However, you want to keep an electronic copy of it for yourself.Which device would best help you do this?

Accepted Answer

A scanner is the best choice as it will allow you to create an electronic copy of the document for your own records. A webcam, keyboard, and camera are not suitable for creating an electronic copy of a physical document.

Question 13

How many bits make a byte?

Accepted Answer

A byte is made up of 8 bits.

Question 14

What should you do before you turn on a laptop for the first time?

Accepted Answer

It is best to fully charge the battery before turning on a new laptop for the first time to maximize battery life.

Question 15

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

Accepted Answer

When a file is saved to the cloud, it is stored on a remote server, typically owned and operated by a third-party service provider. This allows the user to access their files from any device with internet connectivity, as long as they have the necessary login credentials to access the cloud storage service. Flash drives and external storage devices are physical devices that must be attached to the user's device to access the saved files. Internal storage refers to the built-in storage on the user's device and is not typically associated with cloud storage solutions.

Question 16

To resolve major computer issues, computer professionals often suggest restoring the operating system.Which of the following should happen before this step?

Accepted Answer

Before restoring the operating system, it is important to transfer all important files and data to an external storage device to prevent the loss of important data. Disconnecting output devices, the UPS, or removing the internal hard drive are not necessary steps before restoring the operating system.

Question 17

Which of the following is a pointing device you can use instead of a mouse?

Accepted Answer

A touchpad is a pointing device typically found on laptops, and can be used instead of a mouse. The other options listed (keyboard, USB port, projector) are not pointing devices and cannot replace a mouse.

Question 18

Which computer type will take up the most space in a workspace?

Accepted Answer

Desktop computers typically consist of multiple components such as a CPU tower, monitor, keyboard, and mouse, which can take up a significant amount of space in a workspace. Therefore, they are likely to take up the most space compared to tablets, laptops, or all-in-one computers.

Question 19

What kind of device is the camera on a smartphone?

Accepted Answer

The camera on a smartphone is an input device, as it allows the user to input visual information into the phone.

Question 20

Which computer component is primarily responsible for converting input (data) into meaningful output (information)?

Accepted Answer

The Central Processing Unit (CPU) is primarily responsible for processing the input data and converting it into meaningful output information. It is often referred to as the "brain" of the computer, and controls all other components. While components like the hard disk and RAM play important roles in storing and accessing data, the CPU is directly responsible for processing it. The operating system also plays a role in organizing and managing input and output, but it is not primarily responsible for the conversion itself.
