Transport Layer
Transport Layer - allows traffic to be directed to specific network applications
- responsible for multiplexing and demultiplexing traffic
- establishes long running connections
- ensuring data integrity through error checking and data verification
Multiplex - nodes on a network have ability to direct traffic toward many different receiving services
Demultiplex - taking traffic that’s all aimed at same node and delivering it to proper receiving service
Port - 16-bit number that is used to direct traffic to specific services running on a networked computer
