What protocol uses port 118?

SQL Services
HTTP
FTP
IMAP

The correct answer is: SQL Services

Port 118 is used by SQL Services, which is a protocol employed for database communication and management. This port is not as commonly recognized as those for protocols such as HTTP, FTP, or IMAP, but it serves a specific purpose related to SQL networks. SQL Services often handle database requests and data manipulation over the network, allowing applications to store and retrieve data efficiently. The use of port 118 facilitates these functions in environments where SQL databases are accessed remotely, ensuring the appropriate data exchanges between clients and the database server. Understanding this association is important for recognizing how various services operate at the network layer, particularly in the context of database management and communication protocols.
