Introductory Networking (The Osi Model Overview)
Hi, amazing hacker today in this blog I am gonna show you the networking introduction part in TryHackme without wasting time let's dive into the article.
The OSI (Open Systems Interconnection) Model is a standardized model that we use to demonstrate computer networking theory. In practice, real-world networking is based on the much more compact TCP/IP model; however, the OSI model is easier to get an initial understanding from.
The OSI model is made up of seven layers:
Which layer would choose to send data over TCP or UDP?
Which layer checks received packets to make sure that they haven’t been corrupted?
In which layer would data be formatted in preparation for transmission?
Which layer encrypts, compresses, or otherwise transforms the initial data to give it a standardised format?
Which layer tracks communications between the host and receiving computers?
Which layer accepts communication requests from applications?
Which layer handles logical addressing?
When sending data over TCP, what would you call the “bite-sized” pieces of data?
[Research] Which layer would the FTP protocol communicate with?
Which transport layer protocol would be best suited to transmit a live video?
