What is the purpose of the TCP/IP Network Access layer?
- path
determination and packet switching
- data
presentation
- reliability,
flow control, and error detection
- network
media control

bits that will be transferred over the media
- the source application or
process creating the data

layer specific encapsulation
9-
What is the primary purpose of Layer 4 port assignment?
- to
identify devices on the local media
