is an essential aspect of modern communication systems. It involves the connection of computers and other devices to enable the exchange of information. A network typically includes devices such as s and es, which serve as the backbone of the network infrastructure.
A router is a crucial component in a network that forwards data packets between different networks. It uses es, or Internet addresses, to determine the most efficient path for data transmission. IP addresses uniquely identify devices on a network and facilitate communication using the TCP/IP protocol suite.
A switch, on the other hand, operates at the data link layer of the network architecture and connects devices within a local area network (). It handles traffic between devices using MAC addresses, ensuring efficient and secure data transfer.
Networks can be classified into two main types: Local Area Networks (LANs) and Wide Area Networks (s). A LAN is a network that connects devices within a limited area, such as an office building or home. In contrast, a WAN spans a larger geographical area, connecting devices across cities, countries, or continents. Routers play a crucial role in connecting LANs and WANs, enabling interconnectivity between different networks.
To ensure network security, a is often employed. It filters incoming and outgoing network traffic based on a set of predetermined security rules. This helps protect the network from unauthorized access and malicious activities.
The (Domain Name System) is responsible for translating domain names, such as www.example.com, into IP addresses. This translation allows users to easily access websites and other network resources without needing to remember complex IP addresses.
is a widely used technology for establishing wired local area networks. It uses a set of rules and protocols to enable data transmission over a physical medium, typically using copper or fiber optic cables. Ethernet plays a vital role in connecting devices within a network and is known for its reliability and speed.
