2 Transport Layer (Layer 4)
Provides a variety of services between two host computers, including connection establishment and termination, flow control, error recovery, and segmentation of large data blocks into smaller parts for transmission. Layer Name Protocols and Specifications Devices Transport TCP, UDP Firewall

3 Reality Check

4 NetStep Challenge TCP UDP

5 NetStep Resolution TCP UDP I AM NOT SAYING …….. I AM JUST SAYING
CDP operates at what layer of the OSI model TCP UDP I AM NOT SAYING …….. I AM JUST SAYING

6 NetStep Challenge buffering cut-through windowing congestion avoidance
load balancing

7 NetStep Resolution I AM NOT SAYING …….. I AM JUST SAYING buffering

10 NetStep Challenge

11 NetStep Resolution I AM NOT SAYING …….. I AM JUST SAYING
A TCP connection must be established between the workstation and the web server I AM NOT SAYING …….. I AM JUST SAYING

12 NetStep Challenge TCP uses broadcast delivery
TCP provides synchronized communication TCP provides sequence numbering of packets. TCP provides best effort delivery. TCP segments are essentially datagrams
