NEW QUESTION # 314
Which of the following characteristics differentiates DDR4 RAM from DDR3 RAM?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide) CompTIA A+ Core 1 memory standards describe the differences between DDR generations. One of the key improvements in DDR4 over DDR3 is reduced operating voltage, which allows lower power consumption and increased efficiency.
* DDR3 operates at 1.5V (some variants 1.35V)
* DDR4 operates at 1.2V (some variants 1.05V LPDDR4)
This lower voltage is a recognized defining characteristic separating DDR4 from DDR3.
Other differences such as increased speed and internal bank structure exist, but the question specifically asks for the characteristic that differentiates DDR4 from DDR3 - and voltage is the correct, primary distinction used in CompTIA A+ materials.
Why the other options are incorrect
B). Higher latency
DDR4 generally has slightly higher CAS latency numbers, but due to increased speed, real latency is similar.
This is not the standard differentiator referenced by CompTIA.
C). Increased DIMM width
DDR3 and DDR4 standard DIMMs both have a 64-bit data width.
D). Single-sided modules
Both DDR3 and DDR4 can be single- or double-sided; not a differentiating factor.
NEW QUESTION # 315
A technician is installing a new speaker and microphone in a conference room. The technician makes the connections and installs the manufacturer's application for the devices. However, when the technician uses corporate collaboration tools, the input and output devices have not switched to the new speaker and microphone. Which of the following should the technician do to ensure that the new conference devices are working properly?
Answer: D
Explanation:
Collaboration applications use their own audio device settings. Configuring the correct speaker and microphone as the default within the meeting software ensures the application uses the newly installed devices.
NEW QUESTION # 316
While using a computer, a user reports that the system fan begins running loudly and the display starts to distort. Which of the following is occurring?
Answer: B
Explanation:
A loud fan running at high speed alongside graphical distortion are classic signs that the system is overheating - thermal throttling and artifacting occur when components exceed safe operating temperatures.
NEW QUESTION # 317
Which of the following should a technician check when the display of a computer is flickering?
Answer: D
Explanation:
Display flickering is commonly caused by an incorrect or unsupported refresh rate. Checking and adjusting the refresh rate ensures the display updates at a stable frequency supported by both the monitor and graphics adapter.
NEW QUESTION # 318
Each floor at a new corporate facility will have four printers available for all users to print from AH of the printers will be connected with RJ45 and not joined to a domain Which of the following needs to be set up to accomplish this task? (Select two).
Answer: A,C
Explanation:
To allow multiple users to print to networked printers:
Printer shares enable users to access printers shared on the network.
Print servers manage print jobs and provide centralized control of printing.
Why Not B (DHCP server): DHCP is unrelated to print management.
Why Not D (Printer subnet): Subnets group devices but don't manage printing.
Why Not E (SMB configuration): SMB is for file sharing, not specifically print management.
Why Not F (Printer Wi-Fi settings): These settings are irrelevant since the printers use Ethernet.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 4.6, printer configuration.
