kilobyte
If a memory location stores one byte, then a kilobyte is made up of 1,000 locations.
kilobyte
Computer memory is divided into various sizes. A kilobyte (KB) is approximately 1000 bytes (the exact number is 1024)
In standard binary usage for memory a KB is 1024 bytes. In standard decimal usage for disk drives a KB is 1000 bytes. Confused yet?
megabyte
The answer to this question depends on two key factors, the definition of a kilobyte, and that of a memory location:First, is kilobyte meant in the standard engineering meaning of a multiplier of one thousand, or is it mean to represent a factor of 210, commonly known as a kilobyte, but more correctly called a kibibyte?Thus, one kilobyte can mean 1000 bytes, or 1024 bytes.Second, what is a memory location? Most memory types have a bitwise organization, so 1000 or 1028 bytes would refer to 8000 or 8196 bits, respectively, and refer to 8000 or 8196 memory locations thus.Other implementations of memories may implement a different granularity, for example based on 16, 24, 32 or even larger number of bits per location.

With a 20-bit address bus, a computer can address approximately 1,048,576 memory locations, which is equivalent to 1 megabyte of memory.
