3.2 System Memory Flashcards
What is the primary role of RAM in a computer?
To temporarily store data and applications for quick access by the processor.
What are the recommended RAM sizes for office workstations and gaming systems?
Office workstations: at least 8GB. Gaming systems: 16GB to 32GB or more.
What is the memory addressing limit of a 32-bit processor?
4GB of RAM.
Why are 64-bit processors advantageous for memory addressing?
They can address significantly more memory, supporting modern computing needs.
What are common types of memory modules?
DDR3, DDR4, DDR5, and SODIMM for compact systems.
What is the purpose of multichannel memory configurations?
To increase bandwidth by using multiple memory modules simultaneously.
What is ECC memory, and where is it commonly used?
Error-Correcting Code (ECC) memory detects and corrects memory errors and is commonly used in servers.
What is virtual memory, and how does it work?
Virtual memory uses storage as a backup for physical RAM, allowing more memory usage but at slower speeds.
Why is virtual memory slower than physical RAM?
It relies on the slower read/write speeds of storage devices compared to RAM.
What precautions should you take when installing RAM modules?
Handle carefully to avoid electrostatic discharge and ensure compatibility with the motherboard.
What is the difference between DDR3, DDR4, and DDR5 memory?
Each successive generation offers improved speed, bandwidth, and energy efficiency.
What is the benefit of dual-channel memory configurations?
Increased bandwidth and improved system performance by using two memory modules simultaneously.
What type of memory is commonly used in laptops and small-form-factor PCs?
SODIMM (Small Outline DIMM).
Why is ECC memory important in critical systems?
It increases reliability by identifying and correcting memory errors.
How should RAM modules be installed for optimal performance?
In appropriate slots as per the motherboard’s dual-channel or multichannel configuration requirements.
