group of computers and other devices, such as a printer, that are connected by some type of transmission media (i.e. fiber optic cables or radio waves) (Dean, 2010, p.2). Originally “sneakernet” was the only means of electronic source sharing. It involved the transfer of electronic information by physically couriering removable media, such as floppy disks, from one computer to the next (Wikipedia, 2011, para 1).

one and include the advantages and disadvantages. The current technology uses packets which are small files of information wrapped by a header and footer with security information on the both sides.
