FTP

FTP (File Transfer Protocol) is a common network protocol that enables the exchange of computer files between a client and a server on a computer network. As one of the most widely used protocols, it forms an important part of the Internet infrastructure.

The inner workings of FTP
FTP is built on the client-server principle. A client establishes a connection to a server and requests a file transfer. Upon receiving the request, the server processes the request and establishes a connection for data transfer. FTP uses two different connections: a control connection for commands and responses and an information connection for the actual file transfer.

FTP and HTTP: a comparative analysis
FTP and HTTP (HyperText Transfer Protocol) are used to transfer files over the Internet, but they serve different purposes. HTTP is for accessing and retrieving web pages, while FTP is for transferring files. FTP tends to be more efficient for transferring large files, while HTTP is better suited for accessing web content.

The Role of FTP in Today’s Digital World
FTP plays an important role in the digital realm. It is used in applications ranging from web development to software updates and even cloud storage services. FTP’s ability to efficiently handle large files and directories makes it the preferred choice for many companies and individuals.

The security aspect of FTP
In its original form, FTP is not a secure protocol because the data transferred is not encrypted. However, as FTP has evolved, secure versions such as FTPS (FTP Secure) and SFTP (SSH File Transfer Protocol) have emerged that provide secure file transfers by encrypting data during transmission.
