USB Storage
In September 1956 IBM
launched the 305 RAMAC, the first computer with a hard disk drive (HDD). The HDD weighed over a ton and stored 5MB of data.
IBM leased this machine for
$35,000 a year.
NetworkComputers that are connected in order to share information and resources. The main computer on a network is called a file server.
LAN – Local Area NetworkComputers are in close proximity to each other.
WAN – Wide Area NetworkComputers are in a larger geographical
area.
