SAN stands for "Storage Area Network" in its complete form. Block-level data storage is offered via a Storage Area Network (SAN), a dedicated, autonomous, and ultra-speed network that gives different servers access to a common pool of storage devices. Data transmission between the server and storage device as well as data transfer between storage systems are the two major goals of storage area networks. Storage area networks are mostly used to access storage devices from servers, such as tape libraries and disk-based devices. Servers, network infrastructure, and storage make up the three main parts of a storage area network. Nevertheless, ... Read More

In today's world, multimedia apps are important part of our lives. These use various formats, i.e., audio, video, images, and text. But, multimedia apps also present challenges to the design and performance of computer systems and networks. The most important challenge is how to connect different devices and components involved in multimedia processing and communication efficiently and reliably. To address this challenge, Desk Area Network (DAN) has been introduced. It is interconnection of computer equipment based on the Asynchronous Transfer Mode (ATM). ATM is high-speed networking protocol that operates on the data link layer of the Open Systems Interconnection (OSI) ... Read More
