What is the role of the Northbridge in relation to memory?
A. It stores the BIOS
B. It handles I/O devices
C. It manages the communication between CPU, RAM, and graphics
D. It controls power management
Answer: Option C
Solution (By JKSSB Mock Tests)
In traditional chipset architecture, the Northbridge connects the CPU to high-speed components like RAM and PCIe graphics. Modern CPUs often integrate the memory controller, reducing the Northbridge's role.
Explanation:
A parity bit is an extra bit added to data to detect errors (single-bit errors) in memory. It is used in some RAM modules for error detection.
Explanation:
1x speed for Blu-ray is defined as 36 MB/s (or 36 Mbps? Actually, it's 36 Mbit/s? Wait: 1x Blu-ray is 36 Mbps (4.5 MB/s). Let's check: 1x DVD is 11.08 Mbps (1.32 MB/s), 1x CD is 150 KB/s. Blu-ray 1x is 36 Mbps = 4.5 MB/s. But common speeds are faster. Let me verify: Actually, 1x Blu-ray = 36 Mbit/s (4.5 MB/s). Some sources say 36 Mbit/s = 4.5 MB/s. So option A (4.5 MB/s) is correct. However, I've also seen 1x Blu-ray = 36 MB/s? Let's recall: Blu-ray standard defines 1x at 36 Mbps (megabits per second). So 4.5 MB/s. So correct answer is A: 4.5 MB/s.
Explanation:
Flash memory uses floating gate transistors to trap electrical charges (electrons). The presence or absence of charge alters voltage thresholds, representing 0 or 1.
