+allocates a new buffer in a fixed size of [bytes](https://github.com/DeveloperTryingToCodeLikeOtherOfThem/pxt-hardware-programming-docs/blob/master/docs/bytes.md).
 ``` sig
  Buffer.create(null);
 ```
-A **buffer** is contiguous memory.
+A **buffer** is a block of contiguous memory.
+
+Additionally, when allocating a buffer, there is no meaning to represent the bytes. 
+This is because allocating the buffer is simply storing the amount of memory into the RAM (Random Access Memory).
+
+The meaning comes from from how you write or read the bytes, such as using:
+* `buf[index] = value` to set a byte at a specific offset
+* Buffer methods like setNumber to store structured values
+
+## Example
+Store 100 bytes.
+``` ts
+    const buf = Buffer.create(100);
+```
