Which of the following is a measure of memory speed?
A. CAS latency
B. Pins
C. Voltage
D. Capacity
Answer: Option A
Solution (By JKSSB Mock Tests)
CAS (Column Address Strobe) latency is a measure of the delay between a memory read command and the availability of data, indicating memory speed. Capacity is size, voltage is power, and pins are physical connector.
Explanation:
EPROM (Erasable Programmable ROM) can be erased by exposing it to strong ultraviolet light, and then reprogrammed. EEPROM is electrically erasable.
Explanation:
A cylinder consists of the same track number on each platter in a hard disk drive, all at the same distance from the center. This allows the heads to access data without moving.
