Glossary Related to a Wifi router



GlossaryFirst of all let’s understand what a router is because this thing is related to the router: Router is basically a device that is used to spread Wi-Fi signals in some range in a particular area. It is basically used to convert LAN connection into Wi-Fi. Previously when we took LAN connection, there used to be a wire that we could plug in our Laptop or PC to run the internet. But now, we get a router too with LAN connection so that we can run the internet on all our Wi-Fi compatible devices without inserting any wire. The router has LAN ports behind it, and one of them is for Wi-Fi. It means if we insert LAN wire connector into that port, we can run Wi-Fi through the router.

Now let’s get back to terms related to the router. By knowing these terms, you can easily understand your router and control it in a better way. Also, it will help you to understand various things and information about your router that are given on the Internet, like if you want some help, then you should know some terms so that you can understand those help options.

  • DNS (Domain Name Service)

Now let’s understand Domain Name Service or simply DNS. It is basically a service, of which there are many stages, or we can say hierarchical, and it translates domain names into IP addresses. Whenever you type a domain name in your browser, this service is used, and it converts those names into corresponding IP addresses. Now, why did we use word hierarchical? It is because this system of converting domain names into IP addresses involves a network of servers who correspond to each other until they reach to the correct IP address. This thing is very fast, and we didn’t notice any time lag when it occurs.

  • Ethernet (MAC) Address

There are various network adaptors related to a router. We have discussed them earlier. Now, what this MAC address is? It is basically a 48-bit number having hexagonal digits of Layer 2, and it is maintained by IEEE. IEEE stands for The Institute of Electrical and Electronics Engineers. Now, what it does? These digits are basically hardwired into network adaptors. These addresses are mostly assigned by the manufacturer of a network interface controller.  Also, these addresses are stored in hardware like in ROM or by some other technique. It is a unique identifier, and it is assigned to network interfaces for communications.

  • TCP/IP

TCP stands for Transmission Control Protocol whereas IP stands for Internet Protocol. It is basically a protocol that is used for identifying devices, and it also groups them into networks. Currently, the IPv4 version of Internet Protocol is in use. There is one more version also called IPv6. It is the new version, but it is not used as it is under development.

  • Router (Gateway)

It is basically a device, and it is used to send data packets along with networks. First, it checks the address of the target destination. It also dispatches the data packet to another subnet, or we can say the target computer. Router’s IP addresses are usually or

  • Ethernet

It is basically a network protocol, a link layer protocol in the TCP/IP stack and it controls the transmission of the data over a LAN. It is technically called IEEE 802.3 protocol. It has been improved very much over time, and now it can deliver the data at the speed of a gigabit per second.

  • Wi-Fi

It is basically a Wireless local area network. It uses 802.11 protocol which means, it is based on IEEE 802.11 standards.   These things are approved in the Wi-Fi Alliance tests for interoperability, security and application-specific protocols.

  • LAN

It stands for Local Area Network. It basically consists of a set of devices that share a common communication line (wired or wireless) to a server. It spreads over a small area like a building or school. It is very fast.

  • WAN

It stands for Wide Area Network. It is wider than LAN. It may or may not be privately owned or rented. It includes Public networks.

  • MAN

It stands for Metropolitan Area Network. It connects users having computer resources in a very large area, larger than the area covered by Local Area Network (LAN). Its range or area covered is smaller than the region covered by Wide Area Network (WAN).

  • Bandwidth Reservation

There is a range of bandwidth that is available to the users. It is a particular range, and the focus should be on making the best use of the available bandwidth. This process is basically about making priorities to different flows of traffic. It depends on the traffic’s criticality and delay-sensitivity.


In this article, we have seen some terms, some short terms related to router and functioning of Router and Internet. These terms are useful and should be known as these are basics will help you if somehow you got any trouble. So, we hope you have got your answers to sophisticated wifi router terms that you might not have understood prior. So, next time you hear any term related to a Wifi router, you need not be confused.
