______is a legacy memory that uses RIMM memory modules and is named after Rambus Inc.
- A.
Double Data Rate SDRAM (DDR SDRAM)
- B.
Direct Rambus DRAM (RDRAM or Direct RDRAM)
- C.
DDR2 SDRAM
- D.
SyncLink SDRAM (SLDRAM)
Correct Answer
B. Direct Rambus DRAM (RDRAM or Direct RDRAM)Explanation
Direct Rambus DRAM (RDRAM or Direct RDRAM) is the correct answer because it is a legacy memory that uses RIMM memory modules and is named after Rambus Inc. RDRAM was a type of synchronous dynamic random-access memory (SDRAM) developed by Rambus Inc. It was used in some computer systems in the late 1990s and early 2000s. RDRAM offered higher bandwidth and lower latency compared to other memory technologies at the time, but it was more expensive and had compatibility issues.Rate this question:

______ refers to an error checking procedure in which either every byte has an even number of ones or every byte has an odd number of ones.
- A.
ECC (error-correcting code)
- B.
Parity
- C.
System Restore
- D.
Reboot
Correct Answer
B. ParityExplanation
Parity refers to an error checking procedure in which either every byte has an even number of ones or every byte has an odd number of ones. This technique is used to detect errors in data transmission by adding an additional bit (parity bit) to each byte. The parity bit is set to 1 or 0 in a way that ensures the total number of ones in the byte, including the parity bit, is either even or odd. If the number of ones in the received byte does not match the expected parity, an error is detected.Rate this question:

In Windows, memory errors can cause frequent __________ errors which causes a computer to freeze, hang, boot failures, or become unstable.
- A.
Parity
- B.
Disk
- C.
General Protection Fault (GPF)
- D.
Parity Memory
Correct Answer
C. General Protection Fault (GPF)Explanation
Memory errors in Windows can lead to General Protection Fault (GPF) errors, which can cause a computer to freeze, hang, experience boot failures, or become unstable. GPF errors occur when a program attempts to access memory that it does not have permission to access or when there is a violation of memory protection. These errors indicate a problem with the memory management system and can be caused by faulty RAM modules, incompatible hardware or software, or corrupted system files. Resolving memory errors and addressing the underlying cause is essential to ensure the stability and proper functioning of the computer system.Rate this question:

- C.
AT
- D.
NLX
Correct Answer
B. BTXExplanation
The correct answer is BTX. BTX stands for Balanced Technology Extended, which is a motherboard form factor that was introduced as a successor to the ATX form factor. BTX motherboards are designed to improve airflow and cooling within the computer case, resulting in better overall system performance and stability. They also feature a different layout and component placement compared to ATX motherboards. While ATX is still widely used, BTX was intended to address some of the limitations of the ATX form factor and provide a more efficient and optimized design for modern computer systems.Rate this question:
