What does this mean ?

If you don’t understand some words, some technical terms while reading our web pages and tutorials on how to setup your router, here’s the glossary where everything is explained.

Bandwidth Reservation

This is a process that assigns priority flows of data based on the delay, sensitivity, priority, and criticality. The main goal of this process is optimizing the flow and making the best use of the available bandwidth. Optimization ensures that if the network becomes cluttered, the priority segments don’t stop functioning properly.

DNS (Domain Name Service)

DNS is a service that matches the site’s name with the corresponding IP address. Whenever a domain name is entered, a DNS service employs the network of servers and determines the exact address of the domain. This is service is an integral part of the Internet as it converts all IP addresses into meaningful domain names.


Ethernet is a link layer protocol, installed widely in local area network technology (LAN) and it defines how network devices format and transmit the data within the network and how that data is placed on the network connection. It utilizes TCP/IP protocols and is at the core of LAN and Wi-Fi.

Ethernet (MAC) Address

MAC address is sometimes referred as physical address because it is hardwired into the hardware itself. This is a hexadecimal number in a 48-bit format and it’s used for networking and maintained by The Institute of Electrical and Electronics Engineers (IEEE).

LAN (Local Area Network)

Local area network is basically a collection of devices that share the same communication line to communicate with each other or the server. All the computers and peripherals connected to the same local network are the part of that LAN. Examples would be an office network, a warehouse, an entire company, etc.

MAN (Metropolitan Area Network)

MAN networks can vary in size and they cover the space between LAN and WAN telecommunication structures. These networks link users and other resources in a medium sized environment.

Router (Gateway)

The router is the device that is in charge of sending and receiving packages via the network. Basically, it sends the packets of information to the intended address, subnet or a target computer and vice versa. All machines in a network know its exact address and use the router to communicate with other networks.

TCP/IP (Transmission Control Protocol/Internet Protocol)

TCP/IP is basically the communication language used for transferring data on the Internet. It is used for identifying and grouping devices and manages the communication within a network. There are various versions with one of the most commonly used ones being the old IPv4 and the new one IPv6.

WAN (Wide Area Network)

Wide area network is a basically an extended LAN. It works the same way, but covers a wider telecommunication structure. The only difference is that WANs are also used for public networks.


Wi-Fi is basically a name most commonly used for wireless local area networks, especially for ones using the 802.11 specs. This basically encompasses the devices that comply with Wi-Fi Alliance tests and have the Wi-Fi certified badge, which means uniformity in terms of security, interoperability, and application specific protocols.
