What is a LAN and what is its primary use?
A Local Area Network (LAN) is a network that covers a small geographic area, such as a single building or campus. It connects computers and other devices within this area, allowing them to communicate and share resources like files and printers efficiently. LANs are commonly used in homes, schools, and offices to facilitate communication and data sharing.
What are the primary functions of a router in a network?
A router's primary functions include forwarding data packets between different networks and directing traffic on the internet. It connects local networks (like LANs) to larger networks (such as the internet) and ensures data reaches its correct destination by managing IP addresses. Routers also provide security features like firewalls to protect the network from external threats.
How does a switch differ from a router?
A switch connects multiple devices within a Local Area Network (LAN) and uses MAC addresses to forward data to the correct device. Unlike a router, which connects different networks, a switch operates within a single network, directing data internally. It enhances network efficiency by ensuring data is sent only to the intended recipient within the LAN.
What role do access points play in wireless networking?
Access points (APs) are devices that allow wireless devices to connect to a wired network using Wi-Fi. They extend the range of a wireless network, enabling more devices to connect and communicate wirelessly. APs are essential for creating Wireless Local Area Networks (WLANs) in homes, offices, and public spaces, providing flexibility and mobility to users.
What is DHCP and why is it important in a network?
DHCP (Dynamic Host Configuration Protocol) is a network management protocol used by routers to automatically assign IP addresses to devices on a network. This simplifies network management by ensuring each device has a unique IP address without manual configuration. DHCP enhances network efficiency and reduces the risk of IP address conflicts, facilitating smooth communication between devices.
