Summary of Readings

The reading articles for this week provided a great and simplistic introduction to the networking concepts which included brief descriptions of all the layers in OSI and TCP/IP (DoD) model.  The takeaway for me from these readings was getting an understanding of all the protocols which work in sync across all the layers when two ‘hosts’ communicate on a network. As a user, we are mostly interfacing with the application layer, however, I realized everything eventually comes down to bits and the electrical signals when a packet traverses across a network. The readings provided a fundamental understanding of the all the layers and could prove to be a good starting point to understand vulnerabilities in networks.
