FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Data sent over the internet is called a message, but before messages get sent, they’re broken up into tinier parts called packets. These messages and packets travel from one source to the next using Internet Protocol (IP) and Transport Control Protocol (TCP).

Detailed explanation-2: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.

Detailed explanation-3: -Routers come into play when the data is sent between two different networks. Routers examine packets to determine their destinations. They take into account the volume of activity on the Internet, and they send the packet to another router that is closer to the packet’s final destination.

Detailed explanation-4: -The correct answer is Packets. A packet contains a source, destination, data, size, and other useful information that helps the packet make it to the appropriate location and get reassembled properly. The information from the computer is sent over the networks in small units known as packets.
