Question 1

Points: 10 out of 10

In a situation where a handicapped person can only input data into the computer using a stylus or light pen, which keyboard configuration might be the solution?

 A keyboard with internal lighting to support work in low-light conditions.

 A keypad that is projected on an external flat surface.

 A flat waterproof keyboard.

 A split-style keyboard that separates and angles groups of keys into right- and left-hand portions.

Feedback

Correct. This seems to be the best solution since the user could use the stylus or light pen to tap on the displayed keys.

Question 2

Points: 10 out of 10

If you use your desktop computer only for doing schoolwork, which input and output device combination would be best from the options below (considering the best combination of cost, screen resolution, and keyboard design)?

 a gaming keyboard and a 27″ LCD monitor

 a foldable keyboard and a 15″ LCD monitor

 a wireless keyboard and a 24″ LED monitor

 a split-style keyboard and a 30″ LED monitor

Feedback

Correct. The wireless keyboard will work nicely in this situation; and the LED monitor is a very good size.

Question 3

Points: 10 out of 10

You need to back up (make copies of) your critical documents and pictures on your desktop. Which of the following statements would be true for using cloud storage for backups in case your computer experiences a complete failure (will not boot and all files have been lost from the internal hard drive)?

 If your desktop computer or your internal hard drive is not functioning, you can still access those backed up files via another computer with access to the internet.

 You would not need to carry external storage media with you when you use another computer.

 When data is distributed (stored on multiple external websites) there is greater risk of unauthorized physical access to the data.

 All of the above.

 None of the above.

Feedback

Correct. All three statements are true as applied to cloud storage.

Question 4

Points: 10 out of 10

Which device would not be appropriate for holding data, instructions, and information for future use?

 8Gb RAM

 1Tb external hard drive.

 CD or DVD

 Cloud storage

Feedback

Correct. RAM is volatile memory, and all data and instructions will be lost when the computer is turned off.

Question 5

Points: 10 out of 10

Which device would be used to hold data, instructions, and information for future use?

 flash drive

 cloud storage

 hard drive

 none of the above; these are volatile storage devices

 all of the above; these are nonvolatile storage devices

Feedback

Correct. Flash drives, cloud storage, and hard drives are all examples of nonvolatile storage devices.

Question 6

Points: 10 out of 10

Which of the following can be considered an output device?

 stylus

 speaker

 wireless mouse

 microphone

Feedback

Correct. The speaker is used to provide sound data to the user. It is an output device.

Question 7

Points: 10 out of 10

In this diagram of a simple home network, what appears to be missing?

 a server

 an adapter card

 a modem

 a router

Feedback

Correct. Even though this is a wired network, data needs to be sent from and received by the correct computer. The router handles this task.

Question 8

Points: 0 out of 10

In this diagram of a simple home network, what appears to be missing?

 a router

 a server

 an adapter card

 a modem

Feedback

Incorrect. Adapter cards are certainly needed, but they are internal components in each computer and, as such, would not be represented in a diagram of the network

Question 9

Points: 10 out of 10

If you are going to install a completely wireless network in your home, each computer must have:

 a router

 an Ethernet card

 a modem

 a wireless adapter card

Feedback

Correct. This internal component must be found in each computer that needs to connect to the router, and then to the Internet via the modem.

Question 10

Points: 10 out of 10

If you are going to network two computers together using cable connections, each computer must have:

 a modem

 an Ethernet interface card

 a router

 a wireless adapter card

Feedback

Correct. Ethernet interface cards are required to suppport the Ethernet cables which connect the two machine.

Question 11

Points: 10 out of 10

How is data entered into the computer?

 using the circuit board that interfaces with all external components attached to the CPU

 using an electronic device that controls the timing of all peripherals connected to the system unit

 using any type of hardware component that conveys information to one or more people

 using a hardware component that allows submission of data or instructions.

Feedback

Correct. A keyboard, a mouse, a stylus, and a microphone are examples of hardware components that allow the user to enter data or instructions into the computer.

Question 12

Points: 10 out of 10

A webcam would be considered an input device.

 True

 False

Feedback

Correct. A webcam takes an image as input. The webcam itself does not display the image (that is done by an output device such as a monitor).
