What is an FTP Server?
FTP server is a computer server that stores files and allows the users to access the stored files online through the File transfer protocol. It is a shared storage point whereby the users are allowed to download or upload the files in a secure location.
The following are some of the typical FTP server users:
Website developers to upload the files of the website.
• Organization to share information in their firms.
• Educational institutions
• Backup storage systems
• Software distribution
After a user has connected to an FTP server he/she will be expected to provide a username and a password. Once authenticated, they can access files based on the level of their permission.

How FTP Works
FTP is a model of client-server. This means that it consists of two major components:
1. FTP Client
The FTP client is the computer software that is used in creating the connection with the server. Examples include:
• FileZilla
• WinSCP
• Cyberduck
The customer also allows users to scan through their files and drag and drop their files between folders.
2. FTP Server
FTP server is a server that stores files and restricts their access to users. It listens to requests and authenticates information and subsequently grants access.
Connection Process
The process of the elementary FTP connection is the following:
1. User opens FTP client
2. Enters server address
3. Types in usernames and passwords.
4. Connects to server
5. Uploads or downloads files
FTP usually uses:
• Port 21 for communication
• Port 20 for data transfer

This type is used for:
• Public downloads
• Software distribution
• Open resources

2. Authenticated FTP
FTP authentication consists of the user name and password. The authorized users have the access to files only.
This type is used for:
• Company file sharing
• Private data transfer
• Website hosting

SSH File transfer protocol (also called SFTP).
Secures and utilizes safe log-in.
FTPS (FTP Secure)
Uses SSL/TLS encryption.
Secure FTP must be utilized by business.
