is the process of connecting multiple devices together to facilitate communication and data transfer. A vital component of any network is the , which serves as the central hub for all incoming and outgoing network traffic. The router directs data packets to their respective destinations using es. An IP address is a unique identifier assigned to each device on the network, allowing them to send and receive data.
To effectively manage network traffic, a is used to connect multiple devices within a Local Area Network (). Unlike routers, switches operate at the data link layer of the OSI model, enabling them to handle network traffic efficiently.
Communication between devices on a network is made possible through s. These protocols define the rules and formats for data exchange, ensuring compatibility and smooth communication between different systems. , for example, is a widely used protocol that supports wired connections and facilitates high-speed data transfer across LANs.
While LANs are limited to a single location like a home or office, Wide Area Networks (s) span across larger geographic areas. WANs enable the connection of remote locations and facilitate communication between different networks.
To ensure network security, a is deployed. Acting as a boundary between the internal network and the external world, a firewall filters incoming and outgoing network traffic, monitoring for potential threats and preventing unauthorized access.
, or Domain Name System, plays a crucial role in network communication. It translates domain names, such as www.example.com, into IP addresses that routers and switches can understand. This translation allows users to access websites and services using easy-to-remember names rather than complicated IP addresses.
