TestOut A+ Practice Exam 1.2.8
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 - ANS*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.) - ANS*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 - ANS*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
▫ VGA cable
▫ DVI cable - ANS*Answer:* Display Port Cable
You are connecting an older dot matrix printer to a computer. The printer's cable is a
D-shaped connector with 25 pins.
Which port type does the printer connect to?
▫ VGA port
▫ Serial port
▫ USB port
▫ Parallel port - ANS*Answer:* Parallel Port
*Explanation*
A D-shaped, 25-pin connector connects to a computer's parallel port (DB-25 port). *Parallel
connectors* are used with older devices, such as dot matrix printers.
*Serial ports* have nine pins and are used with serial devices (e.g., barcode scanners).
*VGA ports* have 15 pins (three rows of five pins) and are used with VGA monitors. *USB
ports* are rectangular in shape and typically aren't used with older devices.
You are providing telephone support for a user who is trying to connect a computer to a
projector. You know that the projector only has a VGA port.
How would you describe the connector that the user should look for?
▫ Round with 6 pins
▫ D-shaped with 25 pins
▫ Rectangular with one beveled corner
▫ D-shaped with 15 pins - ANS*Answer:* D-Shaped with 15 pins
*Explanation*
