Basic networking terms and concepts in Wireshark

Wireshark is a popular network protocol analyzer that allows users to capture and analyze network traffic in real-time. Here are some basic networking terms and concepts you may encounter when using Wireshark:

1. Protocol: A set of rules that governs the communication between devices in a network. Examples of network protocols include TCP, UDP, and HTTP.

2. Packet: A unit of data that is transmitted over a network. Packets contain information such as the source and destination IP addresses, the protocol being used, and the data being transmitted.

3. IP address: A unique identifier assigned to each device on a network. IP addresses are used to route packets to their destination.

4. Port: A number used to identify a specific service or application on a device. For example, port 80 is typically used for HTTP traffic.

5. Ethernet: A widely-used networking technology that defines the physical and data-link layers of the OSI model.

6. MAC address: A unique identifier assigned to each network interface on a device. MAC addresses are used for addressing at the data-link layer of the OSI model.

7. DNS: The Domain Name System (DNS) is a protocol used to map domain names to IP addresses.

8. HTTP: The Hypertext Transfer Protocol (HTTP) is a protocol used for transmitting data over the World Wide Web.

9. TCP: The Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol used for transmitting data over a network.

10. UDP: The User Datagram Protocol (UDP) is an unreliable, connectionless protocol used for transmitting data over a network.
