Question

A node having only outgoing branches is called as ____ .

• A. Input node
• B. Output node
• C. Incoming node
• D. Outgoing node % Not standard terminology

Hint:

Signal Flow Graph Nodes. Input (Source) Node: Only outgoing branches. Output (Sink) Node: Only incoming branches. Mixed Node: Both incoming and outgoing branches.

Answer 1

The Correct Option is A

This terminology is often used in the context of Signal Flow Graphs or network diagrams representing systems
- An Input Node (or Source Node) is a node that has only outgoing branches
It represents an input variable or source signal entering the system
- An Output Node (or Sink Node) is a node that has only incoming branches
It represents an output variable of the system
- A Mixed Node has both incoming and outgoing branches
Therefore, a node having only outgoing branches is called an input node or source node
