Server and Workstations

Server and Workstations

A server is a part of computer hardware or computer program that provides functionality to devices or other programs called clients. The servers provide services such as sharing data among multiple clients or running computation for a client. A single server can serve multiple clients and vice versa. Similarly, a client process can run on the same device or can connect over a network with the server on a different device. There are various types of servers such as rack servers, tower servers, modular infrastructure, specialty servers, industrial-grade servers, and management solutions.
A workstation is a high-performance special computer that is designed for technical and scientific applications. It has advanced graphics, a large storage capacity, and a powerful central processing unit (CPU). Generally, a workstation refers to a common mainframe computer terminal, a PC linked to a network, and a range of hardware. It is more capable than a PC and less advanced than a server.
Network Storage System

Network-attached storage

Network attached-storage system makes the stored data more accessible to networked devices. It has built-in security, fault-tolerant, and management capabilities. It gives a single point for storage. File sharing becomes easy with the network-attached storage system and they are managed efficiently with reduced costs. It supports multiple operating systems and runs continuous operations that make it hassle-free for the IT department.

Storage area network (SAN)

This storage network is a network of storage devices that provides access to block-level data storage. It accesses data storage devices like tape libraries and disk arrays from the servers and hence, the devices appear as direct-attached storage to the operating system. The storage network area is not accessible through the local area network. The file access provided by SAN is known as shared-disk file systems.
