The basic definition of a computer network is that a computer network connects parts of a distributed architecture, whether those parts are made up of hardware, or virtual or logical resources.Networks are commonly categorized based on their characteristics.We'll talk more about how this distinction is made in the evolution of computer networking step-by-step, from the early mainframe computers onward.The earliest computers had no networks — they were monoliths that crunched numbers through basic mechanical and electrical components.Then, slowly, as the technology evolved, we figured out how to link one physical computer to another.Early simpler computer networks were situations where individual computers and workstations and servers got connected one by one, first by Ethernet and other cabling, and later through wireless connection technologies.In the beginning, those machine-to-machine connections were the only kinds of networking that were available. Instead of computers cabled together, the network data traffic moves in packets, through a wireless or distributed virtual environment, and often, through the web to and from vendor services, like AWS.Virtualization resources include containers and other models where engineers clone an operating system to various nodes and synchronize activity between them.Cloud and Software as a Service (Saas) technologies further abstracted networking, which is now an extremely diverse industry.

A network consists of multiple devices that communicate with one another.
A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. When embarking on digital transformation initiatives, its important to factor in WAN design to avoid poor application performance and customer dissatisfaction.
