An overview of networks
A network is a system of elements linked together. There are many networks around us such as highway systems, electrical grids, and data networks. Data networks surround us. They relate to video services networks, phone and global telecommunication networks, computer networks, and so on. We are going to focus on these types of networks by talking about how we can share data over different types of media such as wires transporting electric pulses or electromagnetic waves facilitating wireless communication.
Before we dive into the details of network implementations for Arduino boards, we are going to describe a model named the OSI model. It is a very useful representation of what a data network is and what it involves.
Overview of the OSI model
The Open Systems Interconnection model (OSI model) has been initiated in 1977 by the International Organization for Standardization in order to define prescriptions and requirements around the functions of communication systems...
