FTP is a widely used protocol for transferring files between computers on a network. It allows users to upload and download files from other individuals or systems, regardless of their operating system.
How FTP works:
Client connects: The client (e.g., a computer running Windows or macOS) initiates the FTP connection by sending a request to the server (e.g., another computer's operating system).
Authentication: The client and server authenticate each other by exchanging usernames and passwords or using other authentication methods.
Transfer starts: Once both parties confirm their identities and are authenticated, the client begins transferring the requested file to the server.
File is delivered: The client continuously checks the server's status and receives the transferred file when it is finished.
Closing connection: When the client finishes the transfer, it closes the connection and releases the resources it used.
Benefits of FTP:
Security: FTP provides robust security mechanisms, such as password protection and encryption, to safeguard sensitive files.
Versatility: FTP can be used to transfer various file types, including documents, images, videos, and software.
Widely supported: FTP is supported by most major operating systems, making it accessible from various devices.
Examples:
Uploading a file: You can use FTP to upload a new document or presentation to your university's server.
Downloading a file: You can use FTP to download a software update or a specific project file from a colleague's computer.
Key points to remember:
FTP is a client-server protocol, meaning it requires both a client and a server to participate in the transfer.
FTP uses a dedicated port for communication, typically port 21.
It is a secure protocol, but it is important to use strong passwords and keep the software updated
