# Memory and Data Storage Units This document describes different units of data storage and how to convert between denary (base 10) and binary (base 2). ## Data Storage Units | Unit | Meaning | |---|---| | Bit | Binary digit (0 or 1) | | Nibble | 4 bits | | Byte | 8 bits | | KB | Kilobyte (1024 bytes) | | MB | Megabyte (1024 KB) | | GB | Gigabyte (1024 MB) | | TB | Terabyte (1024 GB) | | PB | Petabyte (1024 TB) | # Converting Between Denary and Binary There are two main methods to convert between denary and binary numbers: **1. Divide by 2 Method** The example demonstrates converting the denary number 89 to binary. This involves repeatedly dividing the number by 2 and recording the remainders. | Divisions by 2 | Remainder | |---|---| | 89 / 2 | 1 | | 44 / 2 | 0 | | 22 / 2 | 0 | | 11 / 2 | 1 | | 5 / 2 | 1 | | 2 / 2 | 0 | | 1 / 2 | 1 | | 0 / 2 | 0 | The remainders are read in reverse order to get the binary representation 01011001. **2. Binary Number Line Method** This method involves listing the powers of 2 and determining which ones add up to the target denary number. The example shows converting 89 to binary. The binary representation 01011001 is equivalent to 64 + 16 + 8 + 1 # Example Conversions | Denary | Binary | |---|---| | 89 | 01011001 | | (other examples are in the image)| (other binary representations are in the image)| The document provides examples of converting numbers between denary and binary formats.
