What is the purpose of a memory module's SPD (Serial Presence Detect) chip?
A. To increase memory speed
B. To detect memory errors
C. To store the memory's configuration parameters for the BIOS
D. To provide additional storage
Answer: Option C
Solution (By JKSSB Mock Tests)
SPD is a small EEPROM on a DIMM that stores information about the memory module's size, speed, voltage, and timings, which the BIOS reads to configure the memory controller.
Explanation:
A memory map defines the layout of physical memory, including the address ranges assigned to different types of memory (RAM, ROM, I/O devices) in a system.
Explanation:
EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is erased and rewritten digitally by applying specific electrical currents to its pins.
Explanation:
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.
