Start with a Box: Draw a rectangle in the center of your paper or digital canvas. This will represent the TCP layer.
Divide into Segments: Inside the TCP rectangle, draw two horizontal lines to divide it into three segments.
Label the Segments: Label the top segment as "Sender", the middle segment as "Transmission Medium", and the bottom segment as "Receiver".
Add Arrows: Draw arrows between the segments to represent the flow of data. Arrows should go from Sender to Transmission Medium to Receiver.
Label the Arrows: Label each arrow with the specific actions or functions of TCP, such as "Data Transmission", "Acknowledgment", "Error Handling", etc.
Optional Details: You can add additional details like sequence numbers, acknowledgement numbers, and flags if you want to get more specific.
Title and Explanation: Finally, add a title to your diagram, such as "TCP Communication Diagram", and if necessary, include a brief explanation of how TCP works alongside the diagram.
Here's a simple ASCII representation:
Arrows:
Labeling the arrows:
Remember, this is a basic representation. TCP involves more complexities, including error handling, flow control, and congestion control, which you can further elaborate on if needed.
