World of Computer Networking Your CCNA start - Multiplexing and De-multiplexing in the Transport Layer

The video tutorial explains how different applications can connect to remote servers and manage multiple data streams through multiplexing. It covers the concept of multiplexing, where multiple data streams are combined into a single stream at the transport layer, and demultiplexing, where the server separates these streams to direct them to the appropriate applications. The tutorial also discusses the role of ports in the transport layer, explaining how different port numbers help identify the correct application or protocol for data segments. Finally, it introduces the concept of port ranges and their significance in network connections.

What is the primary function of a client when connecting to remote servers?

• To create a single connection

• To disable services on remote servers

• To host multiple applications

• To send data to remote servers

What does multiplexing allow in terms of data streams?

• Encrypting data streams for security

• Deleting unnecessary data streams

• Separating data streams into multiple connections

• Combining multiple data streams into one

Which of the following protocols is NOT mentioned as part of multiplexing?

• FTP

• HTTP

• IMAPS

• SSH

What is the role of demultiplexing on the server side?

• To create new data streams

• To direct data to the correct application

• To combine data streams into one

• To encrypt data for security

What does a destination port number indicate in network communication?

• The source of the data

• The type of data being sent

• The encryption method used

• The application that should process the data
