Electronic schematics are a way of displaying the components and connections within an electronic circuit using basic symbols and connectors. Schematics are generally drawn to make connections easy to visualize, rather than as an actual visual representation of a circuit. In short, they are a means to communicate how to build a circuit, not what the circuit should look like.

There are many different symbols used in schematics, and some drawing standards have changed over the years. For a brief overview on how to read a circuit, see https://learn.sparkfun.com/tutorials/how-to-read-a-schematic.
