Q7: Give one difference between primary and secondary memory.

Answer:  The primary memory is volatile and has limited storage capacity, whereas secondary memory is non-volatile and can store huge amount of data.


Q8: Arrange the following memory units in ascending order of their storage capacities: Kilobyte, Byte, Terabyte, Megabyte, Gigabyte, Geopbyte

Answer: The ascending order of memory units is Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Geopbyte.


Q9: Where can a memory card be used?

Answer: Memory card can be used in digital camera, cell phones, camcorders, portable audio players, video players, PDAs, gaming consoles, laptops, printers etc.


Q10: Define the term byte. Differentiate between a bit and a byte.
