CDMA stands for Code Division Multiple Access. It is a channel access method which is used by several radio communication technologies. It is a digital cellular technology and an example of multiple access. It is generally used for mobile communication.Multiple access means that several transmitters can send information simultaneously over a single communication channel. In this system, different CDMA codes are assigned to different users, and the user can access the whole bandwidth for the entire duration. It optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range.Thus, ... Read More

NASNAS stands for Network Attached Storage. It is storage devices that are linked to a network and provide file access services to computer systems. These devices generally include an engine that executes the file services and one or more devices on which data is stored. NAS uses file access protocols, including NFS or CIFS.NAS provides good access controls and security to support collaboration while also enabling someone who is not an IT professional to administer and manage access to the data via an on-board web server.It is created for those network systems, which can be processing thousands of operations per ...

DASDAS stands for Direct-attached storage. It is computer storage that is connected to one computer and not accessible to another. The System of DAS is attached directly to the computer through the HBA (Host Bus Adapter).As compared to NAS devices, its device connects directly to the server without the network. The modern systems of this storage device include the integrated controllers of a disk array with advanced features.The system of DAS is connected directly to the computer by the HBA (Host Bus Adapter. As compared to NAS devices, its device connects directly to the server without the network. The current systems ... Read More

NASNAS stands for Network Attached Storage. It is storage devices that connect to a network and support file access services to computer systems. These devices generally include an engine that executes the file services and one or more devices on which data is stored. NAS uses file access protocols such as NFS or CIFS.NAS storage frequently has a lower startup cost because the current network can be used. This can be very engaging to small-to-medium size businesses. There are multiple protocols that can be used for file sending including NFS for UNIX clients and CIF for Windows clients. Most NAS ...

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
