- All computers connected to the internet are capable of talking to each other
- We send messages to other computers by way of their ip address and port number (appartment number)
- A running program has to be listening to a port number for a message (living in an apartment)
- There is a very specific format of the messages that computers send to each other. HTTP
- The computer that talks first sends a messsage called a request, the other computer must send another message back called the response.
- We need to be aware of the 5 most import parts of an HTTP message. Host, path, method, headers, body
- We are using express to help us build the software that is listening for messages
