Answer: Standardization

Explanation
Standardization allows components from different manufacturers to be interchangeable. If a component meets the specified standards, it will work in the computer, regardless of manufacturer.
Componentization means that a computer is a combination of several constituent parts that can be easily replaced by a field-replaceable unit (FRU). Firmware is a special type of software that has been embedded in the memory of a hardware component. Plug and play allows devices to work with computers without the need for additional configuration on the computer.

You need to replace a broken monitor on a desktop system. You decide to replace it with a spare monitor that wasn't being used. Even though the monitor is made by a different manufacturer than the desktop computer, it still works with the monitor.

Which computer design concept makes this possible?

▫ Componentization
▫ Standardization
▫ Firmware
▫ Plug and Play

Answer: DVI to HDMI

Explanation
The computer has a DVI connector, while the TV has an HDMI connector. Therefore, you will need to use a DVI-to-HDMI adapter. DVI is a digital signal in the same format as the video portion of HDMI. However, DVI doesn't carry the audio signal like HDMI does. This means that if you are only using the video signal (such as showing a PowerPoint slide show), you can use a simple DVI-to-HDMI plug adapter that changes the physical connections.

The manager of the research and development team needs to make a PowerPoint presentation for her team members (no audio). Her presentation requires her computer to be connected to a large high-definition television. You have been asked to ensure that the computer is connected and functioning properly prior to her presentation.

In the process of setting up the computer, you find that the computer video port (see image 1) is different from the port found on the TV (see image 2).

Which of the following adapters MUST you use to connect the computer to the TV?

▫ RCA to HDMI
▫ VGA to HDMI
▫ DVI to HDMI
▫ RCA to USB
▫ VGA to USB
▫ DVI to USB

Answer: PS/2-to-USB

Explanation
Old legacy computers were connected to the keyboard by a purple colored PS/2 port. A PS/2-to-USB adapter will allow the new ergonomic keyboard, which uses a USB connector, to connect to a legacy computer.
RCA and AUX connectors are used for audio and video. USB-A-to-USB-B adapters generally connect a master device to a slave device. Type B is usually for slave devices.

The computer has a DVI connector, while the TV has an HDMI connector. Therefore, you will need to use a DVI-to-HDMI adapter. DVI is a digital signal in the same format as the video portion of HDMI. However, DVI doesn't carry the audio signal like HDMI does. This means that if you are only using the video signal (such as showing a PowerPoint slide show), you can use a simple DVI-to-HDMI plug adapter that changes the physical connections.

An employee has sustained damage to the tendons and ligaments in his wrist and forearm due to the pronation caused by typing on his straight keyboard. His doctor has recommended that he use an ergonomic keyboard to allow his body to heal. After purchasing the new ergonomic keyboard, you find that this employee's computer only has a round, purple keyboard port (see image 1), which does not match the new keyboard's connector type (see image 2).

Which of the following adapters MUST you use to connect the new keyboard to the old legacy computer port?

▫ AUX-to-USB
▫ PS/2-to-USB
▫ USB-A-to-USB-B
▫ RCA-to-USB
