What are NAS?
NAS : Network Attached Storage Device , they are dedicated file storage system that provide data access to heterogenous group of clients
What are SANs?
SAN :Storage Area Network provide access to consolidated block level data storage
What are medias
In networking, it refers to the physical material used to transmit data
What are WAN?
WAN : Wide Area Network are used to connect networks over large geographic areas
