What Is DNS and How Does It Work? A Complete Guide
When you type a website address such as google.com or comxus.com into your browser, you usually do not think about what happens behind the scenes. Within seconds, the website appears on your screen. One of the key technologies responsible for making this possible is DNS, or Domain Name System. DNS works like the internet’s phonebook. […]
What is Mac Address? How does It Work?
Every device connected to an Ethernet or Wi-Fi network needs a way to identify itself at the local network level. This is where a MAC address comes in. A MAC address is a unique identifier associated with a network interface, such as an Ethernet port or Wi-Fi adapter. Network switches use MAC addresses to decide […]
What Is SFP in Networking? A Complete Guide for Business and Industrial Networks
SFP (Small Form-factor Pluggable) is a compact, hot-swappable network transceiver used in Ethernet switches, routers and other networking equipment. It allows a network device to connect using different types of fiber optic or copper interfaces without replacing the entire switch. SFP is particularly useful in industrial networking because network connections may need to cover long […]
What Is an IP Address? IPv4 vs IPv6 Explained
Every device connected to a computer network needs a way to identify itself and communicate with other devices. Whether it is an IP camera, PLC, SCADA server, laptop, industrial Ethernet switch, access-control controller or cloud server, network communication depends on addressing. This is where an IP address comes in. What Is an IP Address? An […]
What Is an Ethernet Port? Types, Speeds and Applications
An Ethernet port is a physical network interface used to connect a device to an Ethernet network. It allows devices such as computers, IP cameras, PLCs, servers, industrial switches, access-control systems and wireless access points to exchange data over a wired network. Ethernet ports are found on almost every type of modern networking equipment. However, […]
What Are Uplink and Downlink Ports in Networking? A Complete Guide
In an Ethernet network, not every switch port performs the same role. Some ports connect end devices such as IP cameras, PLCs, computers and access-control systems, while others connect one network switch to another or connect an access switch to the core network. These connections are commonly described as downlinks and uplinks. Understanding the difference […]
What Is Bandwidth in Networking? A Complete Guide
Bandwidth is one of the most important concepts in computer networking. It determines how much data a network connection can theoretically carry within a given period. In simple terms, network bandwidth is the maximum data-carrying capacity of a network link, usually measured in bits per second (bps). For a modern Indian industrial facility, bandwidth planning […]
What Is Auto MDI in Networking? How It Works and Why It Matters in Industrial Ethernet
In Ethernet networking, the physical connection between two devices has traditionally depended on using the correct cable type. A straight-through cable was generally used to connect different types of devices, while a crossover cable was used when connecting similar devices. Modern Ethernet networks have largely removed this concern through technologies such as Auto MDI and […]
What Is a Trunk Port in VLAN? How It Works in Enterprise and Industrial Networks
A trunk port is a switch port that carries traffic belonging to multiple VLANs over a single physical Ethernet link. Trunk ports are mainly used to connect network devices such as switches, routers, firewalls, and Layer 3 switches when several VLANs need to travel between them. In an industrial network, a trunk link can allow […]
What Is an Access Port in Networking? How It Works and Where Is It Used?
An access port is a switch port configured to carry traffic for a single VLAN. It is commonly used to connect end devices such as computers, IP cameras, PLCs, SCADA workstations, access-control controllers, printers, and other Ethernet devices to a managed network switch. In an industrial network, access ports provide a simple way to place […]
