FTPyhteyksiä

FTPyhteyksiä refers to File Transfer Protocol connections. FTP is a standard network protocol used for the transfer of computer files between a client and server on a computer network. It is built on the client-server model of computing and uses separate control and data connections. The control connection is used for commands and responses, while the data connection is used for transferring the actual files.

FTP is one of the oldest and most widely used protocols for file transfer. It allows users to upload and download files from remote servers. Common uses include web hosting, where website files are uploaded to a server, and software distribution, where large files are made available for download. Many FTP clients are available for various operating systems, providing a user interface for managing connections and file transfers.

However, standard FTP transfers data and credentials in plain text, making it insecure over untrusted networks. Sensitive information such as usernames and passwords can be intercepted. To address these security concerns, secure alternatives like FTPS (FTP over SSL/TLS) and SFTP (SSH File Transfer Protocol) have been developed. FTPS encrypts the FTP session, while SFTP uses the SSH protocol for a secure and encrypted file transfer. When discussing FTPyhteyksiä, it's important to consider the security implications and choose the appropriate protocol for the specific needs.
