What actually Networking Means ?

Networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.
A network, is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information.

Computer networking enables devices and endpoints to be connected to each other on a local area network (LAN) or to a larger network, such as the internet or a private wide area network (WAN). This is an essential function for service providers, businesses and consumers worldwide to share resources, use or offer services, and communicate. Networking facilitates everything from telephone calls to text messaging to streaming video to the internet of things (IoT).

The level of skill required to operate a network directly correlates to the complexity of a given network. For example, a large enterprise may have thousands of nodes and rigorous security requirements, such as end-to-end encryption, requiring specialized network administrators to oversee the network.

At the other end of the spectrum, a layperson may set up and perform basic troubleshooting for a home
Wi-Fi network with a short instruction manual. Both examples constitute computer networking.



WHAT ARE THE TYPES OF NETWORKING ?

There are two primary types of computer networking:
  • Wired Networking
  • Wire-less Net working

Wired networking requires the use of a physical medium for transport between nodes. Copper-based Ethernet cabling, popular due to its low cost and durability, is commonly used for digital communications in businesses and homes. Alternatively, optical fiber is used to transport data over greater distances and at faster speeds, but it has several trade offs, including higher costs and more fragile components.

Wire-Less Networking :
Wireless networking uses radio waves to transport data over the air, enabling devices to be connected to a network without any cabling. Wireless LANs are the most well-known and widely deployed form of wireless networking. Alternatives include microwave,satellite, cellular and Bluetooth, among others.





As a general rule, wired networking offers greater speed, reliability and security compared to wireless networks; wireless networking tends to provide more flexibility, mobility and scalability.
It should be noted that these types of networking concern the physical layer of the network. Networking can also be classified according to how it's built and designed, encompassing approaches that include software-defined networking (SDN) or overlay networks. Networking can also be categorized by environment and scale, such as LAN, campus, WAN, data center networks or storage area networks.


Components of Networking
Computer networking requires the use of physical network infrastructure -- including switches, routers and wireless access points -- and the underlying firmware that operates such equipment. Other components include the software necessary to monitor, manage and secure the network.

Additionally, networks rely on the use of standard protocols to uniformly perform discrete functions or communicate different types of data, regardless of the underlying hardware.

For example, voice over IP (VoIP) can transport IP telephony traffic to any endpoint that supports the protocol. HTTP provides a common way for browsers to display webpages. The internet protocol suite, also known as TCP/IP, is a family of protocols responsible for transporting data and services over an IP-based network.

Could you provide a more detailed over view on VoIP.
thanks.
