Solution

The correct answer is Option 3: Requires a dedicated path

Key Points

• Packet Switching: Packet switching is a method of data transmission where data is broken into smaller packets for efficient transfer.
• ✅ Data is broken into packets: In packet switching, the data is divided into smaller packets before transmission.
• ✅ Each packet may take a different route: Packets are transmitted independently, potentially taking different routes to the destination.
• ✅ Supports dynamic routing: Packet switching can dynamically adjust routes based on network conditions.
• ❌ Requires a dedicated path: This is not a characteristic of packet switching. Dedicated paths are required in circuit switching (e.g., traditional telephone systems), not packet switching.

Additional Information

• Efficiency: Packet switching is more efficient than circuit switching, as it allows multiple users to share the same network resources.
• Use Cases: Packet switching is used in modern networks, including the internet, where dynamic routing and shared resources are essential.

Hence, the correct answer is: Option 3: Requires a dedicated path
