Cloud storage is a model of networked online storage where data is stored on multiple virtual servers‚ generally hosted by third parties‚ rather than being hosted on dedicated servers.Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs. The data centeroperators‚ in the background‚ virtualize the resources according to the requirements of the customer and expose them as storage pools

The need for more storage is growing. The amount of data produced is doubling in every two years. (in 2010 – 1.8 zettabytes) The cost of creating‚ managing and storing the data is decreasing‚ but can the optical storage expand further? The current Blu-ray lasers emit light in the blue part of the electromagnetic spectrum (about 420 nanometer wavelength). There are ongoing researches using UV light‚ that would probably have to be 200 nm and would provide storage capacities of over 100 GB in a single

Types of Storage Devices A storage device is a device capable of storing data. The term usually refers to mass storage devices‚ such as disk and tape drives (www.webopedia.com). In this paper I will explore different types of storage devices and which ones are optimal for different situations. I will also explain what situations are appropriate for the following devices and explain why: a. Hard disk b. Floppy disk c. RAM d. CD ROM e. Tape Hard Disk A hard disk is a magnetic disk on

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs

Ekanayake IS022 3/20/2014 Access Methods of Secondary Storage Devices Secondary Storage Device is storage medium which is used to store large amount of data permanently until it is changed by user. Though it stores information‚ it cannot be accessed directly by the CPU. The data stored in Secondary Storage Device can be accessed depending upon how it is stored on the device. Mainly there are two methods of accessing data from the Secondary Storage Device. 1) Sequential Access Method 2) Direct
