?In my opinion, a technical analyst, Level 1 up to Administrator, including Cybersecurity analyst, should know the OSI model; this really helps in your troubleshooting analysis.

The OSI (Open Systems Interconnection) model is like a set of rules that helps computers talk to each other and share information. It's divided into seven layers, and each layer has a special job to do. Let's imagine it like building a cake!

  1. Physical Layer: This is the bottom layer, like the cake base. It's all about the physical stuff, like the wires and cables that connect computers. It makes sure the information can travel through the wires properly. (bits)
  2. Data Link Layer: This layer is like the yummy filling between the cake layers. It takes the information and organizes it into small pieces called "frames." It also checks if the information has any mistakes.
  3. Network Layer: This layer is like the frosting on the cake. It adds special addresses to the information, called IP addresses, so it knows where to go. It helps the information find its way across different networks. (packets)
  4. Transport Layer: This layer is like the cake slices. It takes the information and breaks it into smaller pieces called "segments." It also puts numbers on each piece, so they can be put back together correctly.
  5. Session Layer: This layer is like the party planner. It helps different applications on different computers start, have a conversation, and say goodbye when they're done.
  6. Presentation Layer: This layer is like the language translator. It makes sure the information looks the same on different computers, even if they speak different languages. It can also make the information secret and safe.
  7. Application Layer: This is the top layer, like the decorations on the cake. It includes all the fun stuff we do on computers, like playing games, browsing the internet, and sending emails.

So, the OSI model is like building a cake with different layers. Each layer has a special job to make sure the information gets from one computer to another. Just like a cake needs all its layers to be delicious, computers need all the layers of the OSI model to communicate properly. There are many examples explaining the OSI model, I invite you to do a more in-depth study on it.
