World of Computer Networking Your CCNA start - Establishing a Transmission Control Protocol (TCP) Connection

The video tutorial explains the Transmission Control Protocol (TCP), focusing on its connection establishment process known as the 3-way handshake. It details how a TCP connection is initiated, the role of synchronization and acknowledgement flags, and how the server responds to connection requests. The tutorial also covers the process of connection teardown and the use of reset flags for hard resets. The session concludes with a brief mention of the TCP header structure.

What is the main difference between TCP and UDP?

• UDP is more secure than TCP.

• UDP guarantees data delivery, while TCP does not.

• TCP is faster than UDP.

• TCP is connection-oriented, while UDP is connectionless.

What is the purpose of the SYN flag in the TCP 3-way handshake?

• To acknowledge receipt of data

• To terminate a connection

• To reset a connection

• To initiate a connection

During the 3-way handshake, what does the server send back to the client after receiving a SYN flag?

• RST

• FIN

• SYN-ACK

• ACK

What does the ACK flag signify in the TCP 3-way handshake?

• The connection is being terminated

• The connection is established

• The connection is reset

• The connection is pending

Which flag is used to perform a hard reset of a TCP connection?

• SYN

• ACK

• RST

• FIN
