File transfer protocol (FTP)
Explanation:
An information can be defined as an organized data which typically sent from a sender to a receiver. When a data is decoded or processed by its recipient it is known as information.
Generally, there are several channels or medium through which an information can be transmitted from the sender to a receiver and vice-versa. One of the widely used media is the internet, a global system of interconnected computer networks.
There's a standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. One of the very basic rule of the TCP/IP protocol for the transmission of information is that, informations are subdivided or broken down at the transport later, into small chunks called packets rather than as a whole.
The three (3) main types of TCP/IP protocol are;
I. HTTP.
II. HTTPS.
III. FTP.
File transfer protocol (FTP) is used between two or more computers. One computer sends data to or receives data from another computer directly through the use of network port 20 and 21.
