Network devices are hardware components that are used to connect computers and other electronic devices together to form a network. These devices are used to transmit and receive data from one device to another. The most common network devices include routers, switches, bridges, hubs, and firewalls.
Routers: Routers are used to connect different networks together. They use protocols like IP, TCP, and UDP to send and receive data. Routers can also be used to control the flow of traffic on a network.
Switches: Switches are used to connect multiple devices together on a single network. They act as a traffic cop, managing how data is sent and received. The switch allows multiple devices to communicate on the same network.
Bridges: Bridges are used to connect two or more networks together. They are used to allow data to be transferred between networks.
Hubs: Hubs are used to connect multiple devices together on a single network. They act as a central connection point for all the devices on the network.
Firewalls: Firewalls are used to protect networks from unauthorized access. They can be configured to allow only specific types of traffic and block unwanted traffic.
1. Hubs: A hub is a networking device that connects multiple devices or nodes on a network. It passes data from one device to all connected devices and provides the ability for multiple users to share a single internet connection.
2. Switches: A switch is a device used in computer networks to connect two or more nodes together. It is also used to filter and forward data packets between different network segments.
3. Routers: A router is a device that connects two or more computer networks. It acts as an intermediary between computers and forwards data packets between networks using routing protocols.
4. Modems: A modem is a device used to connect computers to the internet. It converts digital signals into analog signals, so that they can be transmitted over telephone lines.
5. Firewalls: A firewall is a device used to secure a private network against malicious attacks. It acts as a barrier between the internet and the private network, blocking any malicious traffic.
