An IP address is a unique address that identifies a device on the internet or a local network

Private IP (internal) addresses are not routed on the Internet and no traffic can be sent to them from the Internet, they only supposed to work within the local network

A public IP (external) address is an IP address that your home or business router receives from your ISP and is used when you access the internet. Public IP addresses are required for any publicly accessible network hardware such as a home router and the servers that host websites

Stands for “Virtual Local Area Network,” or “Virtual LAN.” A VLAN is a custom network created from one or more existing LANs. It enables groups of devices from multiple networks (both wired and wireless) to be combined into a single logical network

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. … One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimise traffic

Internet Protocol television is the delivery of television content over Internet Protocol networks. IPTV offers the ability to stream the source media continuously

Bandwidth is the maximum amount of data transmitted over an internet connection in a given amount of time. Bandwidth is often mistaken for internet speed when it’s actually the volume of information that can be sent over a connection in a measured amount of time – calculated in megabits per second (Mbps)

Voice over Internet Protocol, also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol networks, such as the Internet

A fibre optic cable is a network cable that contains strands of glass fibres inside an insulated casing. They’re designed for long-distance, high-performance data networking, and telecommunications. Compared to wired cables, fibre optic cables provide higher bandwidth and transmit data over longer distances

A single mode fibre-optic cable is constructed to allow only one mode of light to travel through its diametral core. The core’s small size reduces light reflections, increasing the distance that signals can travel and preserving signal quality. Businesses with large bandwidth needs or that communicate across long distances tend to favour a single mode fibre internet connection

A multimode fibre-optic cable is constructed to allow multiple modes of light to travel through its diametral core. The core’s large size increases light reflections, allowing more data to travel across at the cost of reduced signal quality. Because signal quality drops as distance increases, multimode fibre is generally used for short-distance communications across local area networks (LANs)

Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smart phones and wearables), and other equipment (printers and video cameras) to interface with the Internet. It allows these devices–and many more–to exchange information with one another, creating a network
Internet connectivity occurs through a wireless router. When you access Wi-Fi, you are connecting to a wireless router that allows your Wi-Fi-compatible devices to interface with the Internet
