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

Driving with caution is not a bad thing‚ especially while in construction zones‚ at the scene of an accident‚ or inclement weather‚ but to drive like it’s the blizzard of ’98 on every passage is not correct. Flowing with traffic has to happen as well as being alert and aware. So if the flow of traffic is 15

Patty’s Charcoal Drive-In "Sixteen and college-bound"‚ the teen-aged girl in the poem Patty’s Charcoal Drive-In learns the challenges of having a first job: hard work for little pay. Her role is to serve‚ to accommodate customer’s needs by "presenting each tray as if it were a banquet." Then after working hard hopes to merely earn tips from loose change "flung carelessly as the stars." I can understand the challenges of hard work for little pay.

A USB flash drive is a data storage device that includes flash memory with an integratedUniversal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable‚ and physically much smaller than a floppy disk. Most weigh less than 30 g.[1] As of September 2011 drives of 256 gigabytes (GB) are available‚[2] Storage capacities as large as 2 terabytesare planned‚ with steady improvements in size and price per capacity expected.[3] Some allow up to 100‚000 write/erase cycles‚ depending

Limitations of Primary Memory: Limited capacity because the cost per bit of storage is high Volatile - data stored in it is lost when the electric power is turned off or interrupted. So as a result additional memory called auxiliary memory or secondary memory is used. Following are the features of Auxiliary or Secondary Storage: 1. Permanent or Non-volatile Storage: The data which is stored in those devices is not lost when the power is switched off. The data is retained. 2. Voluminous

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

The Theory of Storage THE THEORY OF STORAGE. "THE SUPPLY OF STORAGE REFERS NOT TO THE SUPPLY Of STORAGE SPACE BUT TO THE SUPPLY OF COMMODITIES AS INVENTORIES. IN GENERAL A SUPPLIER OF STORAGE IS ANYONE WHO HOLDS TITLE TO STOCKS WITH A VIEW TO THEIR FUTURE SALE‚ EITHER IN THEIR PRESENT OR IN A MODIFIED FORM. SINCE PRODUCTION IS NOT STABLE FOR ALL COMMODITIES ESPECIALLY ARGICULTURAL CONSUMERS DEMAND THAT THE STORAGE FUNCTION BE SO PERFORMED THAT THE FLOW OF COMMODITIES FOR SALE WILL BE MADE RELATIVELY

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 Access
