Answer 1

Answer)

We connect out laptop to the guest network to view the website using a RJ-45 jack on the table providing a network connection. Also assuming that the DNS information is available. The steps which would occur at each layer of the OSI model from the moment you connect the cable until your web site is loaded in the browser are:

a) Application, Session and Presentation layers - Here the Web browser creates the request and then sends it to the server of the website.

b) Transport and Network layer - Here the TCP/IP stack breaks the request up into packets and also sends them out over the data link layer.

c) Data link layer – The data link wraps each packet into a network frame and then sends it over the physical link to the next switch or router which the computer is connected to.

d) Physical layer - is the wire and electrical signals that transmit the data.
