Detailed explanation-1: -The speed of devices is arranged in ascending order which is floppy being the highest then comes hard disk then RAM and the lowest of all is cache. RAM is a computer storage device that stores data and machine code currently being used.
Detailed explanation-2: -Magnetic disks are better for random data access. Random data access is a type of file access that can be made without reading through all the data. That’s a big benefit if you need to access file frequency. The removable nature of optical disks makes this feature a lot slower.
Detailed explanation-3: -Although optical media is more durable and less vulnerable to environmental conditions than tape, HDDs and SSDs, optical discs are slower than the typical HDD and significantly slower than the SSD and offer lower storage capacities than either.
Detailed explanation-4: -The correct answer is Cache memory. Cache memory is a high-speed storage area for temporary storage. It is the smaller and fastest memory component in the computer.
