Network Device Roles Explained | Generated by AI
Question: Based on the different logical positions of devices in a computer network, network devices can be categorized into ___ and intermediate devices. (Answer: End systems/Terminal devices)
Answer:
In computer networking, devices are classified based on the role they play in the communication process and where they sit logically within the network structure. The answer to your question is Terminal Devices (also commonly called End Systems or Hosts).
1. Terminal Devices (End Systems)
These are the devices that either originate (send) or interface with the data. They are the “start” and “end” points of a network connection.
- Role: To provide an interface between the human user and the communication network.
- Examples:
- Personal Computers (Laptops, Desktops)
- Smartphones and Tablets
- Network Printers
- Servers (Web servers, File servers)
- IP Cameras and IoT devices
2. Intermediate Devices (Network Infrastructure)
These devices connect the terminal devices to each other and ensure that data flows across the network efficiently. They operate “behind the scenes.”
- Role: To manage data as it moves through the network, including regeneration of signals, maintaining information about paths, and directing data to its destination.
- Examples:
- Switches: Connect devices within a single Local Area Network (LAN).
- Routers: Connect different networks and determine the best path for data.
- Firewalls: Secure the network by filtering incoming and outgoing traffic.
- Wireless Access Points (WAPs): Provide wireless connectivity to terminal devices.
Comparison Summary
| Feature | Terminal Devices (End Systems) | Intermediate Devices |
|---|---|---|
| Primary Function | User interface and data processing | Data transport and management |
| Logic Position | Network edges | Network core/infrastructure |
| Interaction | Direct human interaction | Machine-to-machine interaction |
