Why is memory described as temporary in both human and computer contexts?
Press to flip
Like human memory, computer memory often needs power to retain data, and storage can degrade over time.
Why might current storage technologies have a lifespan of less than 10 years?
Current storage media degrades quickly due to factors like environmental conditions and material limitations.
What future advancements are being explored for memory solutions?
Scientists are exploring materials at the quantum level for faster, smaller, and more durable memory solutions.
What causes environmental heat to affect hard drives?
Environmental heat can demagnetize hard drives, affecting their durability.
What role does the CPU play in relation to computer memory?
The CPU processes bits stored in memory, acting as the computer's brain.
How are bits stored in computer memory?
Bits are stored in memory cells that can switch between two states, 0 and 1.
What is a characteristic of optical storage that affects its performance?
Optical storage uses light and dark spots for bits which result in slow latency and lower capacity.
What is a downside of using SSDs despite their speed?
SSDs are prone to wear out with repeated writes.
What material issue affects the durability of current SSDs?
Charge leakage is an issue for floating gates in SSDs.
What is the main difference between Dynamic RAM (DRAM) and Static RAM (SRAM)?
DRAM requires periodic recharging, whereas SRAM does not need refreshing and is faster but more expensive and space-consuming.
What are the roles of memory in computers similar to human memory?
Memory in computers helps in storing information, learning, and planning.
What are the components that make up a cell in DRAM?
Each cell in DRAM has a transistor and a capacitor.
Why is SRAM faster than DRAM?
SRAM is faster because it does not require periodic refreshing, unlike DRAM.
What are the three major types of long-term storage devices?
The three major types are magnetic storage, optical storage, and solid-state drives (SSDs).
How does magnetic storage store data?
Data is stored as magnetic patterns on a spinning disk in magnetic storage.
