What is NAS (network attached storage)?

What is NAS? Isn’t every PC connected to a network also a storage device? How is NAS different than a local server?
Servers which are used in smb businesses dont have enough storage capacity. Reason for this that having large storage devices (harddrives) with redundancy / raids become expensive. Further these drives become a part of the server. Therefore, in order to have more storage space with similar redundancy, NAS is preferred. With nas you can have storage capacities of multiple TBs. These devices can be secured within domains by linking access through active directory (if windows server environment). Further there are UIs which give simple security to share data. SMBs usually use it for document storage, server backups.
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. NAS is specialized for serving files either by its hardware, software, or configuration.
Network-attached storage (NAS) is a type of dedicated file storage device that provides local-area network local area network (LAN) nodes with file-based shared storage through a standard Ethernet connection.
