Computer Data Representation

A kilo in decimal numbers is equal to 1000 or 10³. The closest number using the 2x is 1024 and this is 2¹⁰ which in computing terminology is 1024 bytes of storage, or 262,144 Byte or 1 K(or KB).

25. Therefore, a 256K machine would have ____ x ____ or 262,144 bytes of storage.

How many bytes are in the following numbers?

26. 512K

27. 640K

28. 720K

Using the same principle, a mega (or million) in decimal numbers is equal to 1,000,000 or 10⁶. The nearest approximation for the power of 2 is 1,048,576 or 2²⁰.

29. Therefore, 1 _____ byte is equal to ______ bytes -- or roughly 1 million bytes.
