Internet

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.
Router

A router is a device that forwards data packets between computer networks, creating an overlay internetwork.
Fiber Optic cable

An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.
Network Switch

A network switch is a computer networking device that connects network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often referred to as layer-3 switches or multilayer switches.
Network Topologies

Network topology is the arrangement of the various elements (links, nodes, etc.)
Network Tool Kit

Network utilities are software utilities designed to analyze and configure various aspects of computer networks. The majority of them originated on Unix systems, but several later ports to other operating systems exist.
RJ 45 Connector

The 8P8C (8 position 8 contact, also backronymed as 8 position 8 conductor) is a modular connector commonly used to terminate twisted pair and multiconductor flat cable. These connectors are commonly used for Ethernet over twisted pair, registered jacks and other telephone applications.
Network Card

Main device of networking.
