Project Objective
Distributed Disk Application over the Internet.
Physical
The physical part of the disk would be made from a number of disk fragments in different machines over the network which have different applications or protocol interfaces.
Example for physical disks on the Internet could be: email accounts, ftp sites, peer-to-peer file sharing networks.
Logical
The logical part will give the end user one logic disk which will be the size of the fragments sum.
The application will give the end user one united interface for the logic disk and will hide all other different interfaces for the different physical disks.

Protocols
SMTP
The objective of the Simple Mail Transfer Protocol (SMTP) is to transfer mail reliably and efficiently.
When an SMTP client has a message to transmit, it establishes a two- way transmission channel to an SMTP server. The responsibility of an SMTP client is to transfer mail messages to one or more SMTP servers, or report its failure to do so
IMAP
The Internet Message Access Protocol, allows a client to access and manipulate electronic mail messages on a server. IMAP4 permits manipulation of mailboxes (remote message folders) in a way that is functionally equivalent to local folders. IMAP also provides the capability for an offline client to resynchronize with the server.
