Differences between FTP,HTTP and File System
The major difference between FTP and HTTP is that FTP is a two-way system

- it can be used to copy or move files from a server to a client computer

as well as upload or transfer files from a client to a server. HTTP, on

the other hand, is strictly one-way: "transferring" text, pictures and

other data (formulated into a web page) from the "server" to a client

computer which uses a web browser to view the data.

Another point to bear in mind is that File Transfer in FTP means exactly

that: files are automatically copied or moved from a file server to a

client computer's hard drive, and vice versa. On the other hand, files in

an HTTP transfer are viewed and can 'disappear' when the browser is

turned off unless the user executes commands to move the data to the

computer's memory.

Another major difference between the two systems lies in the manner in

which the data is encoded and transmitted. FTP systems generally encode

and transmit their data in binary sets which allow for faster data

transfer; HTTP systems encode their data in MIME format which is larger

and more complex. Note that when attaching files to emails, the size of

the file is usually larger than the original because of the additional

encoding involved.

Most people have several thousand files on their computer's hard disk, so

imagine how hard it would be to find anything if the files were not

organized. Fortunately, all hard disks use a file system, which organizes

all the files on the disk. The file system is created when you initialize

or format your hard disk. It sets up the root directory and subsequent

directories beneath it. The file system allows you to create new files

and folders, which are added to different parts of the "file tree" on

your hard disk.
