BNC
VGA
The most common analog video connector is a VGA connector
What is the name of the measure that specifies how many times an image can be redrawn on a computer screen in one second?
Refresh rate
Frame rate
Aspect ratio
Refresh rate
Refresh rate defines the vertical scan frequency of a monitor and determines how many times, in one second, an image can be redrawn on the screen. Many LCD monitors have a fixed refresh rate
Which PC peripheral connection type operates at 20 Gbps bandwidth, with a port that provides 18 V and 9.9 W of power?
USB 3.0
eSATA

Thunderbolt v1 and v2 both provide 20 Gbps of data bandwidth. In addition, Thunderbolt ports power the attached peripherals with 18 V and 9.9 W of power
Inside a laser printer, approximately what temperature does the fuser get heated to?
250 F
350 F
450 F
350 F
The fuser heats up to approximately 350° Fahrenheit (~175° Celsius). Do not touch it as it will cause burns
You have a user who needs a custom PC configuration to run common desktop applications and simply meet the recommended requirements for a selected operating system. What should you recommend?
Thin client
Thick client
Home server PC
Thick client
A standard thick client is not really a custom configuration; it’s the standard configuration on which custom configurations are based. In other words, a thick client is a standard client computer system
What are the two power requirements that a PCI expansion bus may have in a desktop computer? (Choose two)
- 7 V
- 3 V
5 V
6.6 V
3.3 V
5 V
PCI slots and adapters are manufactured in 3.3 V and 5 V versions. Adapters are keyed to fit in a slot based on their voltage requirements. Universal adapters are keyed to fit in slots based on either of the two voltages
Which of the following is a standard for a secure cryptoprocessor that can secure hardware (and the system boot process) using cryptographic keys?
