Which device among the following is responsible for directing data packets between different networks, making decisions based on IP addresses, and often connecting multiple networks together?

Correct option is C

Router:
· A networking device that directs data packets between different networks.
· Operates at the network layer (Layer 3) of the OSI model.
· Uses IP addresses to make routing decisions and connects multiple networks together.
· Handles the routing of data between network segments and can connect different types of networks.
Important Key Points:
1. Hub: Simple device, no filtering or routing, broadcasts data to all connected devices.
2. Switch: Filters data within a network segment using MAC addresses, improving network efficiency.
3. Repeater: Extends the physical distance of a network by regenerating signals.
4. Bridge: Connects and filters traffic between network segments using MAC addresses.
Knowledge Booster:
1. OSI Model: Understanding the OSI (Open Systems Interconnection) model is crucial for knowing how different network devices operate at different layers.
2. Network Routing: Routers are integral to network routing, enabling data to travel efficiently between different networks.
3. Device Functions: Knowing the specific functions and capabilities of network devices helps in designing efficient and secure network architectures.
