Circuit Diagram

 Symbols are used in many places in our lives. They are everywhere. This also goes for diagrams as well. Diagrams use symbols to shorten the space/words used. If symbols were not used in diagrams than they would be all very confusing with many words and possibly huge drawings. Symbols do cause problems sometimes because you have to remember all of them. This causes a problem for people with a bad memory. Something that does need symbols are locations/landmarks. This will tell a person where you are going by just showing them a picture. This could also help with directions.
