The world of the Internet, web browsers, and routers can be quite confusing at times. In particular, complex words can make things difficult for beginners. However, understanding these terms becomes essential when you want to choose an Internet plan, work with a web browser, or buy a new router.
On this page, we have prepared an intuitive glossary of common terms related to the Internet, browsers, and routers.
🛜 Routers Glossary
Access Point
An access point is a device that is used to create a wireless network. Access points work by connecting to a router using an Ethernet cable and make the network accessible to Wi-Fi-enabled devices.
Bandwidth Control
Bandwidth control is a feature that lets you prioritize certain tasks over others. For instance, you can set up your router to prioritize low-latency gaming over regular web browsing or content streaming.
Beamforming
Beamforming is a modern wireless networking technology that makes sure that Wi-Fi signals reach different connected devices instead of shooting the signals in a single direction. It helps with speed and reliability.
Bridge Mode
Bridge mode on a Wi-Fi router allows you to turn off the NAT features of the router to enable a third-party router instead. Bridge Mode allows you to avoid multiple networks in a single space.
DHCP (Dynamic Host Configuration Protocol)
Dynamic Host Configuration Protocol can automatically assign IP addresses to devices in a network. This is a time-saving process because you may otherwise have to assign IP addresses to devices manually.
DMZ (Demilitarized Zone)
DMZ, which stands for Demilitarized Zone, is a set of options that will make your Wi-Fi router available to the public internet. It is mostly used for purposes like port forwarding, web hosting, and gaming.
DNS Server Settings
DNS server settings on a Wi-Fi router allow you to replace the ISP-provided DNS server with something like Google Public DNS or Cloudflare DNS. It is a good way to speed up the process of resolving domain names.
Dual-Band Router
A dual-band router can offer wireless access through two different bands: 2.4GHz and 5GHz. The 2.4GHz band is used for long-range, whereas the 5GHz band is for high-speed connections at shorter distances.
Dynamic DNS
Dynamic DNS is mostly used when hosting web servers. It allows you to assign varying IP addresses to a domain name, making it easy to use available IP addresses without resolution concerns.
Ethernet Cable
An Ethernet cable is a wired RJ45 cable made using copper material. It is used to connect network devices together and offer high-speed data transfer.
Failover Router
A failover router is a secondary router that you set up as a backup router. This way, when the main router is offline, the secondary router will kick in and provide you with uninterrupted Internet access.
Firewall
A firewall refers to a software suite that prevents unauthorized devices from accessing your network. It is a necessary piece of security protection when connecting to the Internet and other external networks.
Firmware
A router’s firmware is the software that the router uses to function. Most routers ship with firmware from the manufacturer, but you can upgrade it to later versions or flash a third-party firmware.
Guest Network
A guest network is a dedicated network that you create for temporary users. Devices connected to a guest Wi-Fi network will not have access to the main network and its features.
LAN Port
A Local Area Network port is an Ethernet port where you plug in an RJ45 cable to share network resources. It is used most for devices like printers, scanners, and desktop computers.
MAC Address Filtering
MAC Address Filtering is a security feature that can restrict which devices can connect to the network based on their MAC address. It is better than a filtering system based on IP addresses.
Mesh Network
A mesh Wi-Fi system makes use of multiple wireless access points and nodes to create a widespread wireless network. It can effectively get rid of Wi-Fi dead zones and enable seamless roaming across a building.
MU-MIMO (Multi-User Multiple Input Multiple Output)
MU-MIMO is a feature that allows Wi-Fi routers to seamlessly communicate with many devices at the same time. This technology reduces network lag by a long shot compared to previous technologies.
NAT (Network Address Translation)
A NAT system can create a single IP address that will act as the identity of your entire network. All requests will reach the single IP address, and NAT will translate the request and forward it to the correct device.
Parental Controls
Parental Controls allow you to monitor and control the websites/apps your kids visit. Modern versions allow you to set up Internet downtime, pause Internet access, and set up multiple profiles as well.
Ping Test
A ping test helps you understand how much time it takes for data to reach a server and return. It is measured in milliseconds and is a great way to know how stable the Internet connection is.
PoE (Power over Ethernet)
Power over Ethernet technology allows you to route data signals and power delivery through a single cable. It is widely used to power security cameras, wireless access points, mesh networks, etc.
Port Forwarding
Port forwarding allows your router to retrieve data from the Internet and forward it to a specific device on the network. They are widely used for gaming needs and devices like security cameras.
QoS (Quality of Service)
Quality of Service (QoS) allows you to customize how the Wi-Fi router will prioritize different types of traffic, such as gaming and video streaming. It lets you optimize the connection for specific purposes.
Repeater
A Wi-Fi repeater will receive Wi-Fi signals from an existing router and repeat an amplified version. Although a Wi-Fi repeater can improve range, it will offer lower speeds.
Router Admin Panel
A router admin panel is a web-based interface you can use to access the router’s settings. You can open the page by entering an IP address like 192.168.1.1.
SSID (Service Set Identifier)
Service Set Identifier (SSID) is the technical term for the Wi-Fi network name. A router allows you to set up a unique SSID or even hide the SSID when configuring a network.
Static IP
A static IP address is an IP address that does not change when you reconnect. This type of address is great when you want port forwarding and web hosting.
Tri-Band Router
A tri-band router will have three frequency bands in total. It could be any combination of a 2.4GHz band, a 5GHz band, and a 6GHz band. In most cases, you get two 5GHz bands and one 2.4GHz band.
UPnP (Universal Plug and Play)
Universal Plug and Play allows you to easily connect devices like smart TVs and gaming ports by opening the necessary ports. However, UPnP may cause security issues.
WPS (Wi-Fi Protected Setup)
Wi-Fi Protected Setup (WPS) allows you to connect to a Wi-Fi router by entering a 4/6-digit PIN or pressing a button. While convenient, WPS is prone to multiple security problems.
