Node
A node is a point of intersection or connection between two or more networks. It is a physical or logical device that is used to connect two or more networks together. Nodes can be used to connect different types of networks, such as local area networks (LANs), wide area networks (WANs), and the Internet. Nodes can also be used to connect different types of devices, such as computers, routers, and switches.
History of Node
The concept of nodes has been around since the early days of networking. In the early days of networking, nodes were used to connect two or more computers together. This was done by connecting the computers to a hub or switch, which would then be connected to another hub or switch. This allowed the computers to communicate with each other. As networks grew in size and complexity, nodes were used to connect different types of networks together. This allowed for the sharing of data and resources between different networks.
Comparison Table
| Node | Hub | Switch |
|---|---|---|
| Connects two or more networks | Connects multiple devices on a single network | Connects multiple devices on a single network |
| Can be physical or logical | Always physical | Always physical |
| Can be used to connect different types of networks | Can only be used to connect devices on the same network | Can only be used to connect devices on the same network |
