A few terms and definitions I have learned:
Computer Networking – Two or more nodes that are connected using some type of physical medium, exchanging information using a common networking protocol.
Network Switch – Device that joins multiples of computers together with one local area network (LAN).
Router – Device(s) [WANs] that connect networks together into intranets.

Internet 101
Did you know that:
Bolt, Beranek and Newman created the first computer network during the age of Cold War as part of the ARPA (Advanced Research Projects Agency).
The internet is the network of computers connected together, where as the World Wide Web is the interface in which is used to navigate this large network.
Asia, Europe, and North America have the highest percentage of internet users, 77.7% – which is a total of 1869087778 users.
Home users typically connect to the internet through cable services, internet distributed from corporations. Business users connect to the internet through secure LAN, or WAN networks in which are then connected to the internet.
DNS is Domain Name System, in which maps names to IP addresses, automatically.
Home Network Design
Network Planning and Design is an important prerequisite process to setting up a network. From small home networks to large corporation networks, it helps to plan out what devices connect to the network in what way, through what medium, and to what node(s).
A traditional network planning methodology involves five layers of planning, namely:
(Wikipedia) – Network Planning & Design
– business planning
– long-term and medium-term network planning
– short-term network planning
– IT asset sourcing
– operations and maintenance
Since this is just a home network, small things such as bridges and wireless devices are not difficult to model, and are easily done so in a network diagram.
