Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers.

That also includes many ways in which they transmit data along with the different software they implement. So, communicating worldwide will not be possible if there were no fixed 'standards' that will govern the way user communicates for data as well as the way our devices treat those data. Here we will be discussing these standard set of rules.
What is TCP protocol?
Networks can run multiple data transfer protocols, but 2 are fundamental to most networks: internet protocol (IP) and transmission control protocol (TCP). TCP combines data into packets before they’re sent through an IP. Think about TCP packets as compressed zip files and IPs as email addresses. If your grandparents aren’t on social media and don’t have access to your personal cloud, you have to send them vacation photos via email. Instead of sending those photos 1-by-1, you can bundle them into zip files before sending them over. In similar fashion, TCP combines files into packets before they’re sent across networks through IPs.
What is the difference between a NAS and a general purpose server?

The power consumption of this NAS type is the largest, but its functions are the most powerful. Some large NAS manufacturers such as Synology, QNAP, and Asustor make these types of devices. Max FTP throughput speed varies by computer CPU and amount of RAM. 2 Embedded-system-based NAS – Using an ARM- or MIPS-based processor architecture and a real-time operating system (RTOS) or an embedded operating system to run a NAS server. The power consumption of this NAS type is fair, and functions in the NAS can fit most end-user requirements. Marvell, Oxford, and Storlink make chipsets for this type of NAS. Max FTP throughput varies from 20 MB/s to 120 MB/s. 3 ASIC -based NAS – Provisioning NAS through the use of a single ASIC chip, using hardware to implement TCP/IP and file system. There is no OS in the chip, as all the performance-related operations are done by hardware acceleration circuits.
