Answer:ii. The functions of the device shown above could include:
1. **Data Storage:** The device (assuming it's a storage drive) stores data persistently.
2. **Data Retrieval:** It allows stored data to be accessed and retrieved when needed.
d. Four advantages of using solid-state drives (SSDs) over hard disk drives (HDDs) are:
1. **Speed:** SSDs are significantly faster than HDDs in terms of both read and write speeds. This results in faster boot times, quicker file transfers, and overall snappier system responsiveness.
2. **Durability:** SSDs have no moving parts, unlike HDDs which use spinning disks and mechanical arms. This makes SSDs more durable and less prone to physical damage or mechanical failure.
3. **Energy Efficiency:** SSDs consume less power than HDDs because they do not require motors to spin disks. This can result in longer battery life for laptops and lower energy costs for data centers.
4. **Noiseless Operation:** Since SSDs do not have moving parts, they operate silently compared to HDDs, which generate noise from spinning disks and moving mechanical components.
These advantages make SSDs particularly attractive for use in modern computing devices where speed, durability, and energy efficiency are crucial factors.
