Encoding and Decoding
Encoding and Decoding is a skill on Pengi from Sesson 2: Binary Code in Amplify Science (California) Grade 4.
Key Concepts
The process of digital communication involves two critical steps: 1. Encoding : The sender converts the original information (like a picture) into a pattern of binary numbers ( 0s and 1s ). 2. Decoding : The receiver takes the incoming stream of numbers and reconstructs them back into the original form.
Because the code is mathematical and precise, the decoding process results in a perfect or near perfect copy of the original.
