OSI model

  1. Application layer Users / Apps that interface with the user
  2. Presentation layer Handles everything to do with file's / file extentions. Example: PNG, JPG, GIF
  3. Seesion layer Deals with ports
  4. Transport layer UDP / TCP comes into play here
  5. Network layer This is the layer where stuff gets sent out to the internet. Routers live on layer 3
  6. Data link layer This is the layer where switches live, MAC addreses get assigned here.
  7. Phisical Layer Everything that connects a device to the network, think of wifi signals, ethernet cables. Everything
