What computer component stores settings about devices such as hard drives.
Answer:
CMOS RAM stores settings about devices such as hard drives.
What is the difference between firmware and software?
Answer:
Firmware consists of software (or programming code) that is embedded ina piece of hardware, such as the BIOS routines that are embedded in theROM chips that help to boot your computer. Software is programming code that is found on some type of magnetic media, such as a hard drive.
The BIOS of your computer contains settings for the types of hard drives that are installed and for the current time. True or False?
Answer: False.
These settings are stored in the CMOS. The BIOS are the boot routines that are stored in ROM.
All devices receive their power from the system board. True or False?
Answer: False.
Some devices receive their power from the system board, while others get their power from the power supply.
You are more comfortable working on your laptop as opposed to your 4G tablet. Your laptop is Wi-Fi capable. What would you add to your laptop to allow you to stay connected while traveling?
a) Bluetooth
b) Wi-Fi extender
c) Cellular card
d) GPS
Explanation:
Adding a cellular card to your laptop would enable you to use the cellular network for communication. Bluetooth would not add any consistent connectivity. A Wi-Fi extender does not have the range to support travel. GPS will only enable you to track your laptop.
You are a PC Support technician and you have been asked to select components to build a computer that will be used for CAD/CAM (Computer Aided Drafting/Computer Aided Manufacturing). Which components are the BEST TWO choices?
a) MIDI sound card
b) Onboard graphics
c) Triple channel memory
d) TV tuner
e) Socket 1366 CPU
Explanation:
Intel’s 1366 platform uses an enormous 12MB L3 cache, a triple-channel RAM design as well as a superfast system bus, QuickPath Interconnect or QPI. Although not the latest technology, thanks to Hyper-Threading, this is still a very popular solution on many parallel processors, with the ability to service 12 threads simultaneously. However today Sandy Bridge Core i5 (not in the A+ exam objectives) is a strong alternative. Bottom line is if you are using really processor heavy software like CAD/CAM 1366 is clearly a contender.
Triple channel memory as the name indicates trebles the memory speed and performance. Not too many processors handle this but The LGA 1366 platform does support DDR3 triple-channel. It typically would run 1333 and 1600MHz but, on certain motherboards, it can run at higher clock speeds.
The correct answers are: 3) Triple channel memory, and 5) Socket 1366 CPU
You have upgraded your laptop and find that it no longer fits the docking station you used for home to office portability. Which solution would you find most efficient?
a) Return laptop with one that fits the dock
b) Replace the docking station with a port replicator
c) Enable UPnP
d) Any of these would be efficient
Explanation:
Docking stations have been largely replaced in favor of port replicators. A port replicator takes advantage of USB capabilities and does not require the laptop to be locked into the docking station. Returning the laptop would be highly inefficient and finding a new laptop with the correct fit is no simple task. UPnP could work but would require peripheral device upgrades. UPnP could also lead to a potential security risk. So the correct answer is: b
You are replacing a hard disk and want to get the best performance possible from a standard magnetic HDD. Which rotational speed would you choose on your new hard disk?
a) 10,000 rpm
b) 15,000 rpm
c) 17,000 rpm
d) 54,000 rpm
Explanation:
15,000 rpm is the fastest actual rotational speed from a standard magnetic HDD. 10,000 rpm is slower than 15,000 rpm and 17,000 rpm and 54,000 rpm hard disks do not exist. While SSD technology is becoming more affordable and is faster than magnetic hard disks, SSD technology is not an option in this question.
You are looking at high-performance SSD storage for your new Ultrabook. Your solution should be PCIe compatible and use the non-volatile memory express controller in order to utilize the available motherboard slot. Which of these options is the best choice?
a) SATA 2.5
b) M.2
c) NVMe M.2
d) None of these meets both requirements
Answer: NVMe M.2
Explanation: NVMe M.2 meets your PCIe and non-volatile memory express controller requirements listed above in the question. M.2 offers substantially higher performance. Connecting M.2 to the PCIe bus and the NVMe (non-volatile memory express) controller will provide the highest performance the system will support.
You are setting up a conference room to support 15 users who usually work on the same floor as the conference room. You have been given a wireless router to make sure everyone has a solid connection. In order to ensure the minimum disruption to their service, what service would you disable on the new router?
a) DNS
b) SMTP
c) DHCP
d) NFS
Answer: c
Explanation: Since all of the users are in the same general area, it is best to leave as much of their network configuration information unchanged as possible. As you know the router and the client use DHCP to negotiate IP address leases based on signal strength and quality. So by design, the client will negotiate with the server a few feet away over its normal configuration. This could cause problems with any statically assigned devices that the new router is not configured for. The answer is DHCP.
The internal 802.11b/g Wireless network card on your new laptop needs to be replaced. Which type of device would you expect as a replacement part from the factory?
a) USB
b) Mini-PCIe
c) IEEE1394
d) Bluetooth
Explanation:
The mini-PCIe slot is an internal laptop connection. It is usually accessed through a small access panel. USB and PCMCIA 802.11b/g adapters are available, but these are external devices. The correct answer is Mini-PCIe.
You are at a customer site and have been asked to configure a second monitor on a laptop computer. You go to the display properties and ____________.
a) Click on monitor 2 and select Extend My Desktop
b) Select the dual monitor tab and configure Dual Monitor Mode
c) Select the Adapter Tab and set Dual monitor status to On
d) Click on Monitor 1 and drag to monitor 2
Explanation:
To set up dual monitors in Windows 7 you select the Extend My Desktop check box. This allows both monitors to be treated as a single large workspace. When extended the entire display area can be utilized and you can drag active windows between them seamlessly. The other options given are not available.
