guess the OSI model

• Presentation layer
• preparing data so that it can be used by the application layer
• responsible for translating incoming data the application layer of the receiving device can understand.

• The Session Layer
• Opening and closing communication between the two devices
• Between Transport & Presentation layer

• Layer 1
• Cables
• Switches
• Data converts into a bit stream

• Layer 3
• Facilitates data transfer between two different networks
• Breaks up segments from the transport layer into packets

• Layer 7
• Directly interacts with the users data
• Web browsers rely on it
• Software is not part of this layer
