4. A technician plans to upgrade a laptop's RAM from 4GB to 16GB. Which of the following should the technician do?
Answer: A
Purchase the same architecture of RAM.
Upgrading a laptop's RAM requires that the new RAM module matches the existing RAM architecture to ensure compatibility and optimal performance. Therefore, it is essential to purchase RAM that supports the same architecture as the original.
A) Purchase the same architecture of RAM.
This option is correct because RAM architecture, such as DDR3 or DDR4, determines compatibility with the laptop's motherboard. Using RAM with a different architecture could lead to failure in the upgrade process or suboptimal performance.
B) Configure the laptop's BIOS settings for the RAM upgrade.
While BIOS settings might need to be checked after a RAM upgrade, this option is not essential for the upgrade itself. Most modern laptops automatically detect new RAM without requiring manual BIOS configuration, making this choice less relevant.
C) Purchase RAM with the same column address strobe latency.
This option is misleading. While column address strobe (CAS) latency can affect performance, it is not a primary concern for ensuring compatibility during an upgrade. The architecture of RAM is far more critical for functionality.
D) Purchase the same brand of RAM.
Although using the same brand can be beneficial for warranty and support reasons, it is not necessary for compatibility. Different brands can produce RAM modules that function together, as long as the specifications, particularly the architecture, are matched.
Conclusion
The requirement to purchase RAM with the same architecture is fundamental to ensuring that the new module will function correctly with the existing system. Options B, C, and D, while they may have some relevance in specific scenarios, do not address the crucial compatibility factor that architecture provides, making option A the definitive correct choice.
