What is the essential requirement for every host computer on a network?

Correct option is D

Every host on a network must have a unique IP address to avoid conflicts and ensure proper communication. IP addresses uniquely identify devices on a network, allowing them to send and receive data packets correctly.
Important Key Points:
1. IP Address: A unique identifier assigned to each device on a network. It can be IPv4 (32-bit) or IPv6 (128-bit).
2. Devices on the same network must have unique addresses to avoid collisions.
3. The IP address ensures routing and proper delivery of packets.
Knowledge Booster:
· Different vs Unique IP Address: "Different" can imply unrelated addresses, while "unique" ensures no duplication within the same network.
· Same Network: Devices within the same network share a subnet but have unique IP addresses.
· IPv4 vs IPv6: IPv4 addresses are in the format 192.168.1.1, while IPv6 uses a hexadecimal format like 2001:db8::1.
