A node refers to a device or computer that is part of a network. It can be a computer, server, router, or any other device that is connected and able to communicate with other devices in the network.
Think of nodes as students in a classroom. Each student represents a device or computer in the network. They can talk to each other and share information just like nodes do in a network.
Network: A group of interconnected devices or computers that can communicate with each other.
Server: A powerful computer that provides services or resources to other computers on the network.
Router: A networking device that forwards data packets between different networks.
