Solid-state drives (SSDs) come in multiple form factors, such as, for example, a “stick” resembling a memory module or a 2.5″ box housed in metal. SSDs also come in 3.5″ form factor
Your friend has just finished building a computer. After installing the operating system, all seems fine except that he found that flash drives placed in the USB ports on the top of the case do not get noticed by the OS. Where do you suspect the problem is?
USB settings misconfigured
Motherboard’s internal USB connector disconnected
System clock
Motherboard’s internal USB connector disconnected
Likely the friend forgot to connect the internal USB connector on the motherboard to the USB ports of the case
You wish to protect your system from someone not authorized to start the OS. What is your best option?
Password protect the locked screen
Password protect in the BIOS/UFEI settings
Encrypt the hard drive
Password protect in the BIOS/UFEI settings
The system BIOS/UEFI settings include password protection to not allow system bootup unless someone enters a password. This would prohibit the OS from loading upon boot
What is used to ensure an efficient and effective heat exchange away from the CPU?
Thermal paste
Dihydrogen monoxide coolant
Lower CPU speeds
Thermal paste
Thermal paste is like a grease that ensures that the heat generated from the CPU is efficiently conducted away and into the heatsink. Lowering the CPU speed might result in less heat generated, but it would obviously also result in degraded performance
If you require more USB ports than your system can provide, what is your most cost-effective option?
Install a USB expansion board
Swap peripherals for those requiring different connectors
Replace the motherboard for one with additional USB ports
Install a USB expansion board
A USB expansion board would utilize an expansion slot on the motherboard to provide two to four additional USB ports. Not included as an option, but a USB hub is a cost-effective fix as well
You have been asked to make the touch pad less sensitive. Where would you do this in Windows 10?
Windows Settings l Apps
Windows Settings l Devices
Windows Settings l Personalization
Windows Settings l Devices
Under Windows Settings, you choose Devices, then click Touchpad. Under Taps, there is a pull-down menu named Touchpad Sensitivity
Someone who uses multiple laptops has asked you if it’s possible to synchronize the settings for Internet Explorer across all his devices. Is it possible, and where would you do this in Windows 10?
Not possible
Possible, Under Devices l Sync Your Settings
Possible, Within Microsoft Account l Sync Your Settings
Possible, Within Microsoft Account l Sync Your Settings
you do require a Microsoft account in order to synchronize your settings across multiple devices. Under Windows Settings is Account. After you sign into the account, the option Sync Your Settings is available
What technology allows you to generate a tangible product from a computer-aided drafting application?
Smart card reader
3D printer
Touch pad
3D printer
The 3D printer can be attached locally or, if allowed by the manufacturer, accessible by shared network. A smart card reader is used to integrate smart cards as an authentication factor for your system. A VR headset is used for experiencing virtual reality
An employee whose job duties include having to “sign” digital documents is frustrated with how sloppily the mouse re-creates her signature. What would you recommend to the employee?
Scan her true signature, and then copy/paste the image
Procure a signature pad for signing more naturally
Lessen the mouse sensitivity
Procure a signature pad for signing more naturally
A signature pad is a peripheral device that is essentially a small touch-sensitive pad on which someone re-creates a signature
What is the wiring difference between 568a and 568b networking cable?
Both have 8 wires, but two are switched
586b has only 6 wires
both have 8 wires, but four are switched
Both have 8 wires, but two are switched
The standards 568a and 568b are wiring standards. The difference between the two wiring standards is small but significant: the green and orange wires are switched. Unless both cable ends are terminated the same, mixing 568a and 568b standards will cause problems
What is the difference between a DVI-D and a DVI-I cable?
DVI-I cable sends both audio and video
DVI-I cable sends both analog and digital
DVI-D cable sends both analog and digital
DVI-I cable sends both analog and digital
DVI-I cable sends both analog and digital. A DVI-D cable, however, is only capable of sending digital signals
What is the common purpose of an IDE cable?
Connecting an expansion card to the motherboard
Connecting an optical drive to the motherboard
Connecting a hard drive to a SCSI adapter
Connecting an optical drive to the motherboard
An Integrated Drive Electronics (IDE) cable typically connects a hard drive or optical drive to the motherboard
What is the difference between drive form factors such as M2 and SATA 2.5 inch when installing and configuring solid-state drives?
M2 supports magnetic hard drives running at 15000rpm
SATA 2.5 drives and M2 drives use the same slot
M2 drives can use either the SATA or the PCI bus
M2 drives can use either the SATA or the PCI bus
M2 drives can use either the SATA or the PCIe bus, while a SATA SSD only uses the SATA interface. Magnetic hard drives spinning at 15,000 rpm are obviously not solid-state drives, while both the M2 and SATA 2.5 are solid-state drives
Which of the following is not a difference when selecting 2.5 inch and 3.5 inch hard drives?
While clearly different lengths, both are the same thickness
Generally 2.5 are in laptops, while 3.5 is found in desktops
Both can be found in SATA or IDE standard
While clearly different lengths, both are the same thickness
While clearly different lengths, the 2.5 is also thinner and shorter. Generally, the 2.5 inch drives are used in laptops, whereas the 3.5 inch drives are installed in desktops. Both 2.5 and 3.5 can be found using the older IDE connectors or the SATA connectors, using a smaller data cable and a wider power cable
