Hardware (6) Flashcards
Which two CPU sockets are capable of supporting Intel processors? (Choose two)
LGA1156 (Socket H)
LGA2011 (Socket R)
Socket AM3+
Socket FM2
LGA1156 (Socket H)
LGA2011 (Socket R)
Sockets that support Intel processors are currently named starting with the letters LGA, such as LGA1156 and LGA2011. Socket names that start with AM or FM will support AMD processors and not Intel processors
You are discussing data storage needs with a client who is a videographer and media producer. She needs to store dozens of large files and needs immediate access to them for editing. What is the most appropriate storage technology for her use?
NAS
HDD
SD
HDD
A standard hard disk drive (HDD) will provide her with the highest capacity of the four options and also give her immediate access. Network attached storage (NAS) speaks to its connection and availability, not capacity. If the client required file sharing as well, then using a NAS would be the proper choice. Secure Digital (SD) is a memory card format and does not offer the capacity or immediacy she needs. BD-R is a Blu-ray Disc format. It has good storage capabilities, but not the immediacy for editing
You have a client that wants to build a high-end custom home theatre PC. Which two components will you suggest he install in the computer? (Choose two)
Sound card with surround sound
High-end cooling
Video card with HDMI outputs
Multicore processor
Sound card with surround sound
Video card with HDMI outputs
A home theater PC (HTPC) needs to maximize the audio and video experience. It won’t do a lot of processing or data management, so an upgraded processor or RAM is unneeded. Install a great sound card, a video card with multiple HDMI outputs, and a TV tuner card. (HDMI is capable of supporting 7.1 surround sound, so you may choose to buy one expansion card capable of handling both functions.) Some HTPCs come in a compact form factor, which is just a small case
You are searching for a new monitor on the internet and find a used digital LCD monitor for sale. What are the two most likely types of connector you will find on this monitor? (Choose two)
Composite
DVI-D
HDMI
VGA
DVI-D
HDMI
Digital monitors will have a digital interface, such as DVI-D, HDMI, or miniHDMI . Composite connectors are rarely used on monitors, and VGA is analog, not digital
A technician needs to purchase a new laptop for a manager. The manager has had several laptops fail and wants her new one to have as few components as possible to reduce the risk of failure. Which type of light source technology does not require an inverter and therefore is a better choice?
OLED
Plasma
LED
LED
There is no need for laptops with LED displays to convert the DC power coming into the laptop to the AC needed to power traditional fluorescent backlights because LEDs operate on DC power just like the rest of the laptop. Therefore, systems with LED backlights have no inverter board
Which of the following are typical formats supported by virtual printing? (Choose three)
Print to PDF
Print to XPS
Print to DOC
Print to image
Print to PDF
Print to XPS
Print to image
The four virtual printing options are print to file, print to PDF, print to XPS, and print to image
A bidirectional PCIe 1.1 x1 link provides how much data throughput?
250 MBps
500 MBps
2 GBps
500 MBps
There are four major versions of PCIe currently specified: 1.x, 2.x, 3.0, and 4.0. For the four versions, a single omnidirectional lane operates at a data rate of 250 MBps, 500 MBps, approximately 1 GBps, and roughly 2 GBps, respectively. A bidirectional slot doubles the data rate
Which component in a laser printer is responsible for heating up and melting the toner into the paper to create a permanent image?
Transfer corona assembly
Exit assembly
Fuser assembly
Fuser assembly
Laser printers incorporate a fuser assembly, which uses two rollers that apply pressure and heat to fuse the plastic toner particles to the paper
During which step in the laser printer printing process does a wire or roller apply a strong, uniform negative charge to the surface of the imaging drum?
Charging
Exposing
Transferring
Charging
During the charging step, the charging corona uses a high voltage to apply a strong, uniform negative charge (around –600 VDC) to the surface of the imaging drum
You are installing two new RAM modules into a single channel of a dual-channel motherboard. Which of the following is true?
Both RAM modules need to have the same parameters
The RAM modules can be different sizes but must be the same speed
The RAM modules can be different speeds but must be the same sizes
Both RAM modules need to have the same parameters
When installing dual-channel RAM, be sure that the RAM modules both have the same parameters. In some cases, you might even need to make sure they come from the same manufacturer
Which of the following printer components is not found in a laser printer?
Fusser assembly
Transfer roller
Carriage motor
Carriage motor
Carriage motors are components in ink-jet printers. Laser printer components include a fuser assembly, imaging drum, transfer belt, transfer roller, pickup roller, separator pads, and a duplexing assembly
What type of common printer can potentially release harmful ozone into the atmosphere and therefore may contain an ozone filter?
Laser
Thermal
Impact
Laser
A laser printer uses various high-voltage biases inside the case, and high voltages can create ozone
There are four servers in your server closet. You need to access each of them, but not at the same time. Which device will allow you to share one set of input and output devices for all four servers?
Touch screen
Docking station
KVM switch
KVM switch
The purpose of a KVM switch is to allow you to have multiple systems attached to the same keyboard, monitor, and mouse. You can use these three devices with only one system at a time, and the KVM switch will have a dial or buttons to allow you to switch between systems
A user on your network has an older laser printer with no Ethernet connection. It’s connected to his computer with a parallel cable. He has shared it on the network for others to use. Now, he wants no part of the printer, but others still need to use it on the network. What would be the best upgrade to install in this printer to allow others to send print jobs to it directly over the network?
A network card
An integrated print server
TCP/IP printing
An integrated print server
It sounds like this printer needs to manage its own print jobs; therefore, it probably needs to be its own print server. Installing an integrated print server with a network connection will probably do the trick
A technician needs to perform maintenance on an ink-jet’s dirty paper pickup rollers. What should she use to clean them?
Rubbing alcohol
Mild soap and water
Compressed air
Mild soap and water
Clean pickup rollers (and other rubber rollers) with mild soap and water and not alcohol. Alcohol can dry out the rollers, making them brittle and ineffective. A dry cloth will not remove the dirt or debris, and compressed air would just blow the debris into other internal printer components
