Explore computer communication protocol.

When computers communicate with each other or with other devices, they use a communication protocol. This protocol defines the rules and standards for data exchange between devices. There are many different communication protocols used in computer networks, some of which include:

1. Ethernet: This is a widely-used protocol for local area networks (LANs). It specifies a set of rules for how data is transmitted between devices on the same network.

2. Wi-Fi: This is another common protocol used for wireless networks. It allows devices to communicate with each other using radio waves.

3. TCP/IP: This is the protocol used for communication between devices on the internet. It includes several sub-protocols, such as HTTP (used for web browsing), SMTP (used for email), and FTP (used for file transfers).

4. Bluetooth: This is a short-range wireless protocol used for communication between devices like smartphones, tablets, and computers.

5. USB: This is a protocol used for communication between devices and peripherals like printers, keyboards, and mice.

Overall, communication protocols play a critical role in enabling devices to communicate with each other across different networks and platforms.
