U1. Protocol Stacks
In place to make things easier.
- Lots can go wrong on a computer or network
- Allow protocol designers and implementers to divide up the problems and remain focussed on 1 piece of the problem at a time
- not efficient to allow 1 protocol to handle everything
- Would not be able to write software to implrment a single protocol
- not efficient to allow 1 protocol to handle everything

Logically a web browser virtually communicates with a web server
- Physically the actual communication is down through the interface to the lower layers
- Inerfaces
- Created between the layers to sort out how a protocol talks to the layer below it
- Requests are passed between layers via the interfaces
- Must be simple
- clear understandable design, easy to implement
- Must be elegant
- well designed, only as complex as its needs to be
- Simple/Elegant design allows for easy replacement of different implementations of protocols IE Ethernet interface for a WiFi interface
