SAN stands for Storage Area Network. This is a network of storage devices that can be accessed by multiple servers or computers, providing a shared pool of storage space. Each computer on the web can access the SAN storage as though they were local disks connected directly to the computer.A SAN consists of interconnected hosts, switches and storage devices. The components can be connected using a variety of protocols. Fibre Channel is the original transport protocol of choice. Another option is Fibre Channel over Ethernet (FCoE), which lets organizations move Fibre Channel traffic across existing high-speed Ethernet, converging storage and ... Read More

NVMe stands for Non-Volatile Memory Express. It is a new storage access and transport protocol for flash and next-generation solid-state drives (SSDs) that delivers the largest throughput and fastest response times yet for all types of enterprise workloads.NVMe is a faster way for solid-state drives to communicate with their host systems. It is an optimized and high-controller scalable interface, which is mainly designed to address the need for Enterprise. It supports 64k of parallel command queues. It is much faster than hard disks, which are limited to a single command queue.The main benefit associated with the NVM express is that ... Read More

NFS stands for the network file system. It is a type of file system mechanism that enables data storage and retrieval from multiple disks and directories across a shared network.A Network file system is implemented in a client/server computing model. An NFS server manages the authentication, authorisation and management of clients and all the data shared within a specific file system. Once authorised, users can view and access the data through their local systems, much like they should access it from an internal disk drive.Network File System is a protocol that operates on all networks IP-based. It is implemented in ... Read More

NAS stands for Network Attached Storage. It is storage devices that are linked to a network and support file access services to computer systems. These devices generally include an engine that implements the file services and one or more devices on which data is stored. NAS uses file access protocols, including NFS or CIFS.NAS systems are famous with enterprise and small organizations in many industries as effective, scalable and low-cost storage solutions. They can provide email systems, accounting databases, payroll, video recording and editing, data logging, etc.NAS is beneficial for more than only general centralized storage supported to client computers ...

DIMM represents the "Dual In-Line Memory Module" and is a limited circuit board that manages memory chips. It needs a 64-bit bus to the memory, whereas a single in-line memory module (SIMM) only has a 32-bit path. This allows DIMMs to transfer more information at once.DIMM includes a sequence of memory known as dynamic random access memory (DRAM), which supports primary storage, the main memory that always reads and executes saved instructions or information directly to the CPU.DIMM is an attempt to enhance the previous single inline memory module (SIMM), which facilitates matched pairs. DIMM operates only one circuit board, ... Read More

ATM is a connection-oriented network at a point where the sender or user which access devices are known as end-point, these end-points connected through a user to network interface (UNI) to the switches on the network, these switches provide a network to network interface (NNI).The architecture of the ATM is shown in the figure below.ATM transfers the information through a transmission path which is made up of a logical virtual path and virtual channel. The transmission path consists of the physical cable, which is connected to an ATM switch. The cables have a transfer speed of up to 155 megabits ... Read More

ATM stands for Asynchronous transfer mode. It is a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells. ATMs can be used for efficient data transfer over highspeed data networks. ATM provides real-time and non-real-time services.ServicesThe services provided by ATM are as follows−Available Bit Rate: It provides a guaranteed minimum capacity, but data can be burst to higher capacities when network traffic is lower.Constant Bit Rate: It is used to specify a fixed bit rate so that data is sent in a steady stream. This is analogous to a leased line.Unspecified ... Read More

CIFS stands for Common Internet File System. It is also known as Server Message Block (SMB). It is a network protocol whose most common use is sharing documents on a Local Area Network (LAN).The protocol allows users to manipulate files just as if they were on the local computer. Various operations such as read, write, create, delete, and rename are all supported. The only difference is that the files are not on the local computer and are actually on a small server.The CIFS protocol operates by sending packets from the user to the server. Each packet is a basic request ... Read More

An ultimate form of multiplexing used in parts of the cellular telephone system and for some satellite communication is called Code Division Multiplexing (CDM). The specific version of CDM used in cell phones is called Code Division Multi-Access (CDMA).CDM does not rely on physical properties, including frequency or time. It can depend on an interesting numerical idea such as values from orthogonal vector spaces can be merged and separated without interference. The specific form used in the telephone network is the easiest to learn. Each sender is created a unique binary code Ci that is called chip sequence.Chip sequences are ... Read More

A transmission system is classified as asynchronous if the system enables the physical channel to be useless for an arbitrary time between two transmissions. The asynchronous design of communication is well-appropriated to applications that create data at random (e.g., a user classifying on a keyboard or a user that press on a link to include a web page, reads for a while, and then press on a link to include another page).The drawback of asynchrony improves from the lack of coordination between sender and receiver while the channel is empty. A receiver cannot know how long the channel will remain ... Read More
