# Wireshark

There are 5 pieces of information here:

* Frame 1 -- this is showing details from the physical layer of the OSI model (Network Interface layer of the TCP/IP model): the size of the packet received in terms of bytes)
* Ethernet II -- this is showing details from the Data Link layer of the OSI model (Network Interface layer of the TCP/IP model): the transmission medium (in this case an Ethernet cable), as well as the source and destination MAC addresses of the request.
* Internet Protocol Version 4 -- this is showing details from the Network layer of the OSI model (Internet Layer of the TCP/IP model): the source and destination IP addresses of the request.
* Transmission Control Protocol -- this is showing details from the Transport layer of the OSI and TCP/IP models: in this case it's telling us that the protocol was TCP, along with a few other things that we're not covering here.
* Hypertext Transfer Protocol -- this is showing details from the Application layer of the OSI and TCP/IP models: specifically, this is a HTTP GET request, which is requesting a web page from a remote server.
