What are three main functions of a router?

Three main functions of a router include: Packet Forwarding: Routers forward data packets between different computer networks. They examine the destination IP address of each packet and determine the best path for it to reach its destination, ensuring efficient data transmission across interconnected networks. Routing: Routers use routing protocols to communicate with other routers and … Read more

What is the NTP standard for?

The NTP standard specifies a protocol for synchronizing clocks across computer networks. It defines how time servers and clients exchange timestamps and perform adjustments to ensure consistent and accurate timekeeping throughout the network. NTP is used for synchronizing clocks across computer networks to ensure accurate timestamps for various network activities, such as logging events, coordinating … Read more

What is a router vs. modem?

A router and modem serve different roles in a network setup. A modem is a device that connects your network to your internet service provider’s network.
