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:* 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. Drag the computer function on the left with its associated hardware component on the right. (Each option may be used more than once.) - ✔✔️*️Answers:* Hard disk = Long-term storage Printer = Output Keyboard = Input CPU = Processing Speakers = Output RAM =Processing DVD-RW = Input Long-term storage Microphone = Output Input *Explanation* *Input:* Mouse, Keyboard, Scanner, Microphone *Output:* Monitor, Speaker, Printer *Processing:* CPU, RAM *Long-term Storage:* Hard disk drives, Solid-state drives, Optical drives, Flash drives. You are looking at a female TRS connector on the computer. Which device uses this connector? ▫ Keyboard ▫ Speaker ▫ Joystick ▫ Monitor - ✔✔️*️Answer:* Speaker *Explanation* A *TRS* connector is used with audio connectors such as speakers and microphones. *Keyboards* use either a PS/2 connector or a USB connector. *Joysticks* typically use a USB connector, though some connect through a DB-15 connector. *Monitors* use one of the many graphic ports, such as a VGA port, DVI port, or HDMI port. You have purchased a new LED monitor for your computer. On the back of the monitor, you see the following port (pictured below). Which type of cable should you use to connect the monitor to your computer? ▫ Display Port cable ▫ HDMI cable *Fiber S/PDIF* - sends a digital audio signal to high-end audio devices, such as home theater systems. *Audio jacks* - connects analog audio devices (such as speakers, headphones, and microphones). Consider the cable connectors used by various peripheral devices (pictured below). Drag the letter on the left to the peripheral device on the right that would most likely use the connector type. - ✔✔️*️Answers:* External storage device = G Analog monitor = D Video camera = C HDTV = A Dial-up modem = H Digital monitor (without audio) = E Network adapter = F Headphones = B *Explanation* *HDMI* - used to send high-quality digital video and audio signals to LCD monitors and HDTVs. *Fiber S/PDIF* - used for home theatre systems or Dolby Digital surround sound systems. *IEEE 1394* - used to connect devices that require fast communication speeds, such as video cameras and external hard drives. *VGA (DB-15)* - used by analog monitors. *DVI* - used by digital monitors and does not carry audio. *RJ45* - used by Ethernet network adapters and other networking devices. *USB* - used by USB devices (such as external storage devices). *RJ11* - used by dial-up modems. TRS jack - used by analog audio devices (such as speakers and headphones). Which of the following BEST describes the DisplayPort interface used for connecting video monitors to computers? (Select TWO). ▫ DisplayPort carries both analog and digital signals. ▫ DisplayPort is electrically equivalent to DVI and HDMI. ▫ DisplayPort can send both video and audio signals over the same cable. ▫ DisplayPort uses a lower voltage than DVI or HDMI. - ✔✔️*️Answers:* ▫ DisplayPort can send both video and audio signals over the same cable. ▫ DisplayPort uses a lower voltage than DVI or HDMI. *Explanation* DisplayPort is an alternative to an HDMI connector. DisplayPort uses a different signal format than DVI or HDMI. However, DisplayPort supports sending DVI or HDMI signals over the same port using a simple adapter. DisplayPort uses a digital-only signal. To connect a VGA monitor to a DisplayPort, you need a special active converter that re-formats the signal for analog devices. Like HDMI, DisplayPort can send audio signals over the same cable (if audio is supported by the video card and monitor). DisplayPort uses lower voltage than DVI and HDMI You are helping a customer over the phone. The customer needs to connect a monitor that uses a digital interface. Which port should you instruct her to look for on the back of her PC? ▫ DVI ▫ USB ▫ SVGA DB-15 3-row ▫ Serial DB-15 - ✔✔️*️Answer:* DVI *Explanation* Modern digital monitors use a DVI connector (typically DVI-D or DVI-I). Serial DB-15 connectors are used for external serial devices such as modems. DB-15 3-row connectors are used to connect older analog SVGA monitors. USB ports are used to connect a variety of devices, but not a monitor. The CEO of your small company has asked you to connect his laptop computer to the small conference room LED TV. The CEO will be showing a new promotional video that demonstrates the new company strategy through images and sound. Which of the following cable types would work BEST for connecting his laptop to the display? ▫ VGA ▫ Composite ▫ HDMI ▫ DVI - ✔✔️*️Answer:* HDMI *Explanation* HDMI is the default cable standard for newer electronic devices, such as Blu-Ray players and LED TVs. *HDMI* can carry both digital video and audio signals. Most modern computers include an HDMI port. *DVI and VGA* only supports video signals. *Composite* cables support video, but not audio. Which connector on the back of a computer is used to attach a mouse to a modern PC system? ▫ High-density (three row) female DB-15 ▫ RJ45 ▫ USB B ▫ Low-density (two row) female DB-15
