### Understanding FTP and its Connection Mechanism

**Question:**

2. Why does FTP open a separate connection for transferring the file?

**Explanation:**

The File Transfer Protocol (FTP) uses a separate connection for file transfer to optimize the process. FTP employs two types of connections:

1. **Control Connection:** This connection is used to send commands and receive responses between the client and server. It remains open throughout the session.

2. **Data Connection:** This connection is temporarily opened specifically for transferring files or directory listings. By using a separate data connection, FTP can efficiently manage the transmission of large files and maintain control command integrity without interference.

**Conclusion:**

The dual-connection approach in FTP ensures a clear distinction between command/response interactions and the actual data transfer, enhancing the reliability and efficiency of file transfers.
