TCP Quiz
The Transmission Control Protocol
How TCP allows clients and servers to communicate.
Course Details
Early network engineers realized that computers would need agreed-upon protocols for sharing data. One of those protocols is the Transmission Control Protocol and in this course we’ll explain how it works and its impact on end users' experience.
Learning Objectives
- What it is built for vs other protocols
- Ports and Sockets - 2 lines of transmission.
- Ports - logical endpoints of a network connection
- Allow ports to be linked to applications - data to port = data for application
- Sockets are an abstraction of a port and IP pair
- Socket pairs are two sockets paired to build a connection.
- Ports - logical endpoints of a network connection
- The Handshake
- Syn : Syn-ACK : ACK
- Data transfer
- IP fragmentation / segmentation (packets)
- Packet Headers
- Maximum segment size (MSS)
- Transmission Order
- Packet loss detection
- Loss packet retransmission
- Congestion control
- Effects on End User experience
