Why Interviewers Ask This
Understanding network topology and device roles is essential for troubleshooting and design. Interviewers want to see if you know the difference between hubs, switches, routers, and gateways.
How to Answer This Question
Define nodes as any device connected to a network. List types like computers, printers, routers, and switches. Explain the specific function of each. Differentiate between active and passive nodes. Mention edge nodes vs core nodes in large architectures.
Key Points to Cover
- Endpoint devices
- Intermediate devices
- Routing vs switching
- Network roles
Sample Answer
Nodes in a network include endpoints like computers and printers, as well as intermediate devices like routers and switches. Routers direct traffic between different networks, while switches manage traffic within a local network. Each node plays a specific role in ensuring data reaches its destination efficiently and securely.
Common Mistakes to Avoid
- Limiting definition to computers only
- Confusing hub with switch
- Ignoring wireless nodes
