FTP vs SFTP vs HDFS vs NTFS vs EXT2, EXT3

I just want to know how these protocols and file systems are related with each other, where each one is used.

FTP vs SFTP vs HDFS vs NTFS vs EXT2, EXT3

any help would be appreciated.

Thanks.

Solution

  • FTP is an old File Transfer Protocol, similar to HTTP but specialized for moving large files.

    sftp is a totally different protocol. It is tunneled over ssh and is therefore encrypted.

    HDFS is the Hadoop distributed filesystem. It is designed to hold many petabytes of data in a single filesystem image.

    NTFS, ext2, and ext3 are operating system specific disk filesystems. NTFS is the primary filesystem on most Windows computers. ext2 used to be the de-facto Linux filesystem and has since been replaced by ext3 and now ext4. All of the ext filesystems are related and you can upgrade from ext2 -> ext3 -> ext4 in place.
