what are the functions of local area network
Storage area Network is a dedicated network that provides access to consolidated, block level data storage. It is a high speed and special purpose network.
Network Attached Storage is short for NAS, which is computer storage connect to a network. RAID is a hard drive or storage container, which provide access to the file network.
Advantage everyone on the network should have access. The disadvantage is that if the network storage is not security protected anyone could gain access
Storage area Network is a dedicated network that provides access to consolidated, block level data storage. It is a high speed and special purpose network.
For an attached computer a network drive functions as a storage device in a business or in a home on a local access network (LAN). For businesses it is usually on a server to share computers together.
A network is not attached to a storage as storage is just for keeping information and documents on and a network is the way that multiple computers talk to each other and access the internet.

Direct - Attached Storage (DAS) functions as a digital storage system which is attached to a server but does not have a storage network. It is mainly used to show the difference between an NAS (Network Attached Storage) and DAS.
A Storage Area Network (SAN) is a dedicated network of storage devices that are not otherwise accessible through the local network (e.g. there is no OS to interface with). This allows servers to have access to large blocks of storage that appear to be local to the server, but are in reality physically separated. This can make backups easier, or provide access to large storages of media files (such as a site like YouTube).
A storage area network (SAN) can be described as a separate network of storage devices that are physically removed from, but still connected to, the main enterprise network. SANs evolved from the concept of taking storage devices and storage traffic off the LAN and creating a separate back-end network specifically designed for data.In essence, A SAN is a separate network to handle storage needs. The SAN decouples storage tasks from specific servers and creates a shared storage facility across a high-speed network. The collection of networked storage devices can include hard disks, tape libraries, and CD arrays.In traditional client server LANs, data were stored on devices (typically disk drives) inside or directly attached to the server. Network Attached Storage (NAS) systems were the next step in the evolution of LAN storage systems. NAS separated storage devices from the server and connected them directly to the network. SANs go one step further by allowing storage devices to exist on their own separate network and communicate directly with each other over very fast interfaces. Users access these storage devices via servers that are connected to both the LAN and the SAN. The SAN arrangement improves client-to-storage access efficiency, as well as direct storage-to-storage communications for backup and replication functions.
False,Server controls access to the hardware, software, and the other resources on the network and provides a centralized storage area for program, data, and information.
