Networking Hardware

Routers

Devices that forward data packets between computer networks, directing traffic based on IP addresses and ensuring data reaches its intended destination.

Switches

Network devices that connect multiple devices within a local area network (LAN) to communicate with each other, using MAC addresses to forward data to the correct destination. They operate at the data link layer and can also function at the network layer to offer additional features such as traffic management and routing capabilities.

Managed switch

A managed switch is a network device that allows network administrators to configure, manage, and monitor the behavior of the switch. Unlike unmanaged switches, managed switches provide advanced features such as VLAN support, traffic prioritization, and remote management capabilities.

Unmanaged switch

A type of networking switch that operates without user intervention, providing basic connectivity between devices in a LAN. Unmanaged switches are typically plug-and-play and lack advanced features for configuration or monitoring.

Access point

A networking device that extends wired networks by allowing wireless connections, facilitating communication between wireless and wired devices. Access points often support multiple Wi-Fi standards and allow for the expansion of network coverage.

Firewall

A network security device that monitors and controls incoming and outgoing traffic based on predefined security rules to protect against unauthorized access. Firewalls can be hardware-based, software-based, or both, and may offer features like traffic proxying and intrusion detection.

Hub

A basic networking device that connects multiple Ethernet devices, making them act as a single network segment. Hubs transmit data packets to all connected devices without filtering. Hubs operate at the physical layer, receiving data packets and broadcasting them to all ports, which can lead to network collisions.

Cable (Broadband)

Cable broadband is an internet connection that utilizes coaxial cables to provide high-speed data services through radio frequency signals. It allows for multiple services, including internet, television, and phone, using the same infrastructure.

Digital subscriber line (DSL)

A high-speed internet connection that uses standard telephone lines to transmit data. DSL allows for simultaneous voice and internet service, providing dedicated bandwidth and faster speeds compared to traditional dial-up connections.

Optical network terminal (ONT)

A device that connects fiber optic lines to the customer's network, converting optical signals into electrical signals for internet, television, and phone services. ONTs are essential in fiber-to-the-home (FTTH) setups, providing high-speed connectivity.

network interface card (NIC)

A hardware component that enables a device to connect to a network, allowing for data communication over wired or wireless connections. Network interface cards (NICs) facilitate internet access and network communication between computers or other devices. They can be built-in or added as expansion cards, and often support different standards like Ethernet or Wi-Fi.

software defined networking (SDN)

An approach to computer networking that allows for the management of network services through abstraction of lower-level functionality. SDN separates the control plane from the data plane, enabling centralized control of the network and enhancing flexibility and efficiency.
