Encode/Decode

The time when you need to think before you talk is when you get arrested because everthing that you say to the cop is used agiasnt you in the court of law. 

Before you talk you have to think about you are going to say and that is encode. You always have to think about what you say when you talk other wise you will never talk. It's wierd how you think before you talk which you would never know.
Encode- process by which information from a source is converted into symbols to be communicated.

For decoding you convert things into stuff then you say them so they dont come out wrong.
Decode- reverse process, converting these code symbols back into information understandable by a receiver.
