Kilobyte (KB) A kilobyte is 1,024 bytes. 2 or 3 paragraphs of text. Megabyte (MB) In computing, the least significant bit (LSb) is the bit position in a binary integer representing the binary 1s place of the integer. Similarly, the most significant bit (MSb) represents the highest-order place of the binary integer. The LSb is sometimes referred to as the low-order bit or right-most bit, due to the convention in positional notation of writing less significant digits further to the r… two people that look alike
