Which component is missing from a Solid State Drive (SSD) that is fundamentally present in a traditional mechanical Hard Disk Drive?
A. A physical read/write actuator arm and spinning platter
B. Internal firmware instructions
C. A connection interface data bus port
D. An integrated circuit controller

Solution (By JKSSB Mock Tests)
SSDs are purely electronic devices that use flash memory chips, meaning they lack the spinning platters, spindle motors, and moving read/write arms found in mechanical HDDs.
Explanation:
DDR stands for Double Data Rate, meaning the memory transfers data on both the rising and falling edges of the clock signal, effectively doubling the data rate.
Explanation:
