Magnetic tape data storage

In 1995, the first digital camcorders came out and were smaller in size. Later the camcorders came with a storage media like a flash memory or SD cards. In 2004, the first wearable Go Pro camera comes out for people to record or take still pictures without having to hold on to them. The cameras can be worn on the body, around the neck, on the head, lapel, chest

organizations, as more people are realizing the power and benefits of cloud environments. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Clouds can be classified as public, private or hybrid Overview Cloud computing, or "the cloud", focuses on getting the most efficiency out of the shared resources. Cloud resources

Until the personal computers invented IBM used to develop Card Punches, Tabulator, Office Copiers, Floppy Disks, Winchester Storage Technology, Magnetic Tape Vacuum Colum and Chinese Character Type Write, Mini and Main Frame Computers. IBM invented a computer in 1975 named as IBM-5100 Portable Computer; the 5100 desktop computer was more likely to the IBM 1130 in storage capacity and performance but small and easy to use as an IBM Selectric Typewriter. All these products made the company to stay

Superconductivity INTRODUCTION We've all heard about superconductivity. But, do we all know what it is? How it works and what are its uses? To start talking about superconductivity, we must try to understand the how "normal" conductivity works. This will make it much easier to understand how the "super" part functions. In the following paragraphs, I will explain how superconductivity works, some of the current problems and some examples of its uses. CONDUCTIVITY Conductivity

Bit strings composed of zeros and ones are the most usual way to represent, change and communicate information. This data however s subject to errors due to a variety of factors, such as deterioration of magnetic tape over time, or a scratch on a CD or DVD. Coding theory uses techniques that can help find the errors. However if there are too many errors, the techniques may not always work. One of the first techniques is the error detecting codes, which adds a parity check bit to the end of the bit

Digital radiography (DR) is a revolutionary invention in radiography. With this technology, no cassette is needed for an x-ray examination meaning that there is no need to reload films or to erase imaging plate in every examination. This is a distinctive feature which conventional radiography and computed radiography (CR) do not have. DR was first introduced in 1996 (Carroll, 2011). Miniature electronic x-ray detectors are used as the image receptor. The detectors enable the direct capture of the

Perhaps the earliest device for working out sums was the abacus. This began as a clay tablet into which grooves were cut. Pebbles were then placed or taken away from grooves to perform addition and subtraction. (Our word calculation comes from the Latin word calculus meaning 'pebble'). Because the pebbles were likely to become mislaid, they were later replaced by beads threaded on to wires and mounted in a frame. By moving the beads backwards and forwards, addition, subtraction, division and multiplication

DATA WAREHOUSE COMPONENTS & ARCHITECTURE Lecture Note # 02 The data in a data warehouse comes from operational systems of the organization as well as from other external sources. These are collectively referred to as source systems. The data extracted from source systems is stored in a area called data staging area, where the data is cleaned, transformed, combined, deduplicated to prepare the data for us in the data warehouse. The data staging area is generally a collection of machines where simple

History Data has always been analyzed within companies and used to help benefit the future of businesses. However, the evolution of how the data stored, combined, analyzed and used to predict the pattern and tendencies of consumers has evolved as technology has seen numerous advancements throughout the past century. In the 1900s databases began as “computer hard disks” and in 1965, after many other discoveries including voice recognition, “the US Government plans the world’s first data center to

exhibiting high surface toughness but reduced ductility.56 The relative proportion of the two bonding types is highly dependent on the deposition method and processing parameters.57 Values of Young’s modulus have above 900GPa have been obtained.58 Nuclear magnetic resolution (NMR) and electron energy loss spectroscopy (EELS) are common techniques to characterise the hybridization of DLC films.59 Many potential applications exist due to the unique combination of properties DLC exhibits.
