Buffers

Buffer in Node.js

• The Buffer class was introduced as part of the Node.js API to make it possible to manipulate or interact with streams of binary data.
• Popular character sets: Unicode and ASCII. These are defined rules of what number represents each character.
• Character Encoding: defines how many bits are used to represent the number. Ex: UTF-8
• Stream: a sequence of data being moved from one point to the other over time.
• Buffer: The "waiting area" where data is kept while the computer waits for all the data to arrive

Byte Ordering

• Big-Endian Byte Ordering: Bytes are stored in order from left to right
• Little-Endian Byte Ordering: Bytes are stored in reverse order from right to left
