Examines PC memory system to identify different types of memory and their main characteristics
Compare SRAM and DRAM in terms of speed and application.
What is one application of EEPROM in modern devices?
How does access time differ between registers and secondary storage?
Why is there a trade-off between cost and capacity in memory systems?
List two types of non-volatile memory and their uses.
Answers and Descriptions:
Answer: SRAM is faster, used in cache; DRAM is slower, used in main memory.
Description: SRAM’s static design offers speed for small, critical data in cache memory, while DRAM’s dynamic design suits larger, less frequent data access in main memory.Answer: EEPROM is used in BIOS chips to store firmware that can be updated.
Description: EEPROM’s ability to be electrically erased and rewritten makes it ideal for storing updatable firmware in computers and devices, ensuring system flexibility.Answer: Registers have the fastest access time, while secondary storage has the slowest.
Description: Registers, located in the CPU, provide near-instant access for active processes, while secondary storage like hard disks is slower due to mechanical operations.Answer: Faster memory (e.g., cache) is expensive with low capacity, while high-capacity memory (e.g., HDD) is cheaper but slower.
Description: The trade-off balances performance needs with budget constraints, using a hierarchy to optimize overall system efficiency for various computing tasks.Answer: ROM (stores firmware) and flash memory (used in USB drives).
Description: Non-volatile memory retains data without power, making ROM ideal for permanent storage of system firmware and flash memory for portable storage in devices like USB drives.
