Answer 1

The correct answer is Router.

Key Points

A router is a networking device that connects two or more network segments.
It operates at the network layer (Layer 3) of the OSI model.
Routers are responsible for forwarding data packets between computer networks.
They determine the best path for data to travel from its source to its destination.
Routers can connect different network architectures, like Ethernet and Wi-Fi.

Additional Information

Network Layer (Layer 3)
- This layer is responsible for logical addressing and routing.
- It determines how data is transferred between devices in different networks.
Switches vs. Routers
- Switches operate at Layer 2 (Data Link Layer) and are used to connect devices within the same network.
- Routers operate at Layer 3 and are used to connect different networks.
Types of Routers
- Home Routers: Typically used in domestic environments to connect to the internet.
- Core Routers: Used by internet service providers (ISPs) to handle large volumes of data traffic.
- Edge Routers: Positioned at the edge of an ISP network to connect to external networks.
Routing Protocols
- Examples include OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), and EIGRP (Enhanced Interior Gateway Routing Protocol).
- These protocols help routers determine the best path for data transmission.
