Which range defines Registered Ports?

• A. 1024-49151
• B. 1-1024
• C. 0-1023
• D. 49152-65535

Answer: (C)

Port numbers are organized into three ranges to keep standard services distinct from custom applications and temporary connections. The registered ports are the range from 1024 through 49151. This block is designated for applications or vendors that want an officially recognized port assignment to avoid conflicts with other services. The other two ranges serve different roles: well-known ports (0–1023) host standard services like HTTP or SSH, and dynamic/private ports (49152–65535) are used for ephemeral, client-side connections. So, the range that defines Registered Ports is 1024 to 49151.
