Worked Solution & Example Answer:Nina wants to transfer photos from a digital camera to an external secondary storage device - OCR - GCSE Computer Science - Question 2 - 2019 - Paper 1
Step 1
Define what is meant by 'secondary storage'.
Answer
Secondary storage refers to non-volatile storage devices that are used to store data permanently. Unlike primary storage, such as RAM, secondary storage retains data even when the power is turned off. It is used to store large amounts of data and can include devices like hard drives, solid-state drives, CDs, and USB flash drives.
Step 2
Step 3
State four characteristics of secondary storage devices that Nina should consider when choosing a device.
Answer
- Capacity: The amount of data the storage device can hold, which is essential for transferring large photo files.
- Speed: The read and write speeds of the device can affect how quickly files can be transferred.
- Portability: How easy the device is to carry, especially if Nina needs to transfer files between different locations.
- Durability: The ability of the device to withstand physical damage and ensure data integrity over time.
