NEW FORM TO STORE INFORMATION

Online Storage: Today you must also speak of this way of storing information. This form allows you to free space of desktop and move files to remote hard drives normally provided to ensure the availability of information. In this case we can speak of two types of online storage: a short-term storage usually aimed at transferring large files via web, another long-term storage, designed to store information that normally would occur in the personal computer's hard disk .

As are the delivery of files to e-mail or other web pages that are used by people to store information, this is when you do not have the resources of storage devices that allow a person to save the files to devices portable.

WHAT HAVE MEANING OF STORAGE DEVICES IN OUR LIVES?

Since the creation of storage devices so we can see how fast you move them to become more competitive and efficient devices in the technology world. The first units were sold in sizes of 8 MB, 16 MB, 32 MB and 64 MB. Currently the capacity of USB flash drives reach up to six Gigabit, equivalent to 6,000 MB.

But besides the storage capacity is at stake speed read / write, the time it takes for the USB to transfer data to the computer. Early models had a speed of 12 MB per second. Today the new USB 2.0 or high speed, with speeds of 480 MB per second, allowing moving large amounts of data in just seconds.

At present, we find that a USB memory can be more convenient than a CD or floppy disk, because thanks to its design can withstand bumps, scratches, falls, among others.

Each USB vary in price, by brand and capacity. There are 128 MB, 512 MB, 1 GB and 2 GB, circulating as currency in North America reports 4, 5 and 6 gigabytes, costs range from 12 to 70 dollars.Keep in mind that the USB is connected to the machine through electrical impulses, which means always, before removing the USB from the computer, be sure to notify the operating system you're using to avoid damage.

The transfer is not a major problem, because thanks to its small size and light weight, can be loaded into your pochet or, as is fashionable, with a cord around the neck.

Clearly, the storage devices are our best weapon in the great stream of information coming into our hands every day, and we need to carry wherever we go.

Why are the storage devices important to the Industry?

The best way to convey our information is through storage devices. These artifacts are advances that provide us with the continuous introduction of new technologies to market. The innovation of what we know and allow us to better comfort for student, college student, teachers and all those who need to carry large amounts of information, and pass from one computer to another. That's why the best solution to all our technological problems. We must open the door to technology.

More information about storage devices!

Storage devices are tools that help us store information and carry it from one place to another. Well, we find that many of them are portable, but there are others who cannot be carried from one place to another, but still serve to save our documents, files and others within them. They are currently considering technologies that are improving every day and bring new ways to store our information. Have greater capacity to memory and we can even find them at small sizes and easy to carry.

Storage devices generally classified by their characteristics that separate them from each other. Some examples of storage devices are: USB, floppy disk, Hard disk, compact disc, memory stick, Micro card, RAM, DVD, VCD, mp3, mp4 and other humans to help make life more comfortable and fewer setbacks to carry information to various locations.

THE IMPORTANCE OF HAVING A SUPPORT SYSTEM

How much does your information and work you have on your PC? Where to buy the photos of those wonderful holiday you spent or that party so much fun? What do you do if the project would pay huge dividends to your business, away from nowhere? The value of our information often exceeds the cost of equipment, unfortunately when we learn that lesson is too late.
We recommend that no matter if the machine is portable or desktop, perform a backup or backup data regularly. Because if you think for a moment than the material value that has the team and our information is quantifiable and time invested in it are a great price. Moreover when the work environment, loss of information means not only time that is measurable and valued, but we can also lose customers and therefore enough money. There is a significant percentage of companies worldwide for claims problems of fire, flood, viruses, power failures and oversights, have lost all their information and have no backups are those within the company in safe places or out of these, as companies have simply disappeared.

If we want to avoid terrible headaches due to the loss of our information must follow the following tips:

• Support regular information on CD, DVD, external drive or Pen. Any of these mass storage devices have the function of support, but do you use? Depends 100% on the amount of information they need to do a backup and a mechanism was used, whether it is manual or automatic.
• Supporting information that is important and what is not according to your recovery, too. This is because today is not so important but at the least expected moment you need it. A very important fact is that whenever information is important, whatever it is you have on your PC, because if not, does not make sense to store it in your computer, and less to spend time searching, purchase or generate .

• Always fully support the following folders on your PC or Notebook:

◦ The "My Documents" in its entirety. Here most of the existing programs store their information. In this folder is always the default, where information is stored Word, Excel, PowerPoint, music, pictures, videos, etc.

◦ The "Favorites" folder in its entirety. Here are stored Internet addresses when you manually save are important to maintain.

◦ The folder "Outlook" in the case of postal system for those using Microsoft Outlook. When one supports this folder, is backing the contacts, mail, tasks, calendar, etc.
• Create a backup of the PC used by a Ghost. This mechanism generates an identical disk image and allows that after a disaster strikes, the PC can be fully recovered within minutes, including operating system and programs or software. A Ghost is how to support operating systems (eg Windows XP and programs eg Word) and can be stored in DVD or external drives with the ability to recover fully at the time of the generation of Ghost.

• Have installed a UPS (Uninterruptible Power Supply). This system is a device that provides stability in the electrical flow to the PC or devices such as printers, scanners. Its function is to prevent electric shock both high and low, and also serves as the primary feed energy stored in their batteries once interrupts the flow of electricity, the various devices connected to it for a few minutes. Thus, it prevents an implement to be burned by a shock or not reaching record information and therefore, lose or damage the hard disk. There are different UPS market according to customer needs. There is from some autonomy that lasts about 10 minutes to some that last for hours.

Characteristics of storage

Characteristics of storage

Volatility

Non-volatile memory 

Will retain the stored information even if it is not constantly supplied with electric power. It is suitable for long-term storage of information. Nowadays used for most of secondary, tertiary, and off-line storage. In 1950s and 1960s, it was also used for primary storage, in the form of magnetic core memory.

Volatile memory 

Requires constant power to maintain the stored information. The fastest memory technologies of today are volatile ones (not a universal rule). Since primary storage is required to be very fast, it predominantly uses volatile memory.

Differentiation

Dynamic random access memory 

A form of volatile memory which also requires the stored information to be periodically re-read and re-written, or refreshed, otherwise it would vanish.

Static memory 

A form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied. (It loses its content if power is removed).

Mutability

Read/write storage or mutable storage 

Allows information to be overwritten at any time. A computer without some amount of read/write storage for primary storage purposes would be useless for many tasks. Modern computers typically use read/write storage also for secondary storage.

Read only storage 

Retains the information stored at the time of manufacture, and write once storage (Write Once Read Many) allows the information to be written only once at some point after manufacture. These are called immutable storage. Immutable storage is used for tertiary and off-line storage. Examples include CD-ROM and CD-R.

Slow write, fast read storage 

Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and flash memory.

Accessibility

Random access 

Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage.

Sequential access 

The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.

Addressability

Location-addressable 

Each individually accessible unit of information in storage is selected with its numerical memory address. In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans.

File addressable 

Information is divided into files of variable length, and a particular file is selected with human-readable directory and file names. The underlying device is still location-addressable, but the operating system of a computer provides the file system abstraction to make the operation more understandable. In modern computers, secondary, tertiary and off-line storage use file systems.

Content-addressable 

Each individually accessible unit of information is selected based on the basis of (part of) the contents stored there. Content-addressable storage can be implemented using software(computer program) or hardware (computer device), with hardware being faster but more expensive option. Hardware content addressable memory is often used in a computer's CPU cache.

Capacity

Raw capacity 

The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes).

Memory storage density 

The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).

Performance

Latency 

The time it takes to access a particular location in storage. The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage. It may make sense to separate read latency and write latency, and in case of sequential access storage, minimum, maximum and average latency.

Throughput 

The rate at which information can be read from or written to the storage. In computer data storage, throughput is usually expressed in terms of megabytes per second or MB/s, though bit rate may also be used. As with latency, read rate and write rate may need to be differentiated. Also accessing media sequentially, as opposed to randomly, typically yields maximum throughput.

Examples of Storage Devices

Compact Disk: is an optical disk used to store digital data. It was originally developed to store sound recordings exclusively, but later it also allowed the preservation of other types of data. The technology was eventually adapted and expanded to encompass data storage CD-ROM, write-once audio and data storage CD-R, rewritable media CD-RW, Video Compact Discs (VCD), Super Video Compact Discs (SVCD), PhotoCD, PictureCD, CD-i, and Enhanced CD

 Random-access memory (RAM): is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (i.e., at random). "Random" refers to the idea that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.

The word RAM is often associated with volatile types of memory (such as DRAM modules), where the information is lost after the power is switched off. Many other types of memory are RAM, too, including most types of ROM and a type of flash memory called NOR-flash

 Floppy disk: is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell.

Floppy disks are read and written by a floppy disk drive or FDD, forms enjoyed nearly three decades as a popular and ubiquitous form of data storage and exchange, from the mid-1970's to the late 1900's. While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have now been superseded by USB flash drives, external hard disk drives, optical disks, memory cards and computer networks. 

 Memory Stick: is a removable flash memory card format is also used in general to describe the whole family of Memory Sticks. In addition to the original Memory Stick, this family includes the Memory Stick PRO, a revision that allows greater maximum storage capacity and faster file transfer speeds; Memory Stick Duo, a small-form-factor version of the Memory Stick (including the PRO Duo); and the even smaller Memory Stick Micro (M2). In December 2006 Sony added the Memory Stick PRO-HG, a high speed variant of the PRO to be used in high definition still and video cameras.

Optical jukebox: is a robotic data storage device that can automatically load and unload optical discs, such as Compact Disc, DVD, Ultra Density Optical or Blu-ray disc and can provide terabytes and petabytes of tertiary storage. The devices are often called optical disk libraries, robotic drives, or autochangers. Jukebox devices may have up to 2,000 slots for disks, and usually have a picking device that traverses the slots and drives. The arrangement of the slots and picking devices affects performance, depending on the space between a disk and the picking device. Seek times and transfer rates vary depending upon the optical technology.
