The myth of the paperless office.


The statistics are music to the ears of data-storage companies but a little scary for those who have to manage, organize, and retrieve information:

In 2002, humans stored about 5 exabytes of new information on paper, film, optical, or magnetic media--a number that doubled in the past three year's. One exabyte is the equivalent of 1 billion gigabytes (most PCs today come with 40- to 100-gigabyte hard drives). Five exabytes, according to the New York Times, are equal to the sum of every word ever spoken by humans since the dawn of time.

That is a 30 percent increase in stored information since 1999, the last time the global study "How Much Information?" was conducted by the University of California at Berkeley's School of Information Management and Systems. The information area with the biggest percentage increase in data was, unsurprisingly, hard disk drives. The study found the amount of stored information on these increasingly high-capacity storage media increased by up to 114 percent from 1999.

According to the study, magnetic storage A medium for holding information (data, voice, video, etc.), such as tape and disk. The medium can be erased and reused over and over again. In the digital world, information is recorded by writing tiny spots (bits) of negative or positive polarity on tapes and disks. A read/write head discharges electrical impulses onto the moving ferromagnetic surface. Reading is accomplished by sensing the polarity of the bit with the read/write head. is by far the preferred medium for storing information and is the fastest growing, with shipped hard drive capacity The amount of storage on a hard disk, measured in gigabytes. Your capacity requirement is derived from the size of your applications, but mostly the amount of data you need to store. Multimedia files such as graphics, animations and video take up considerably more space than text. See byte, hard drive and hard disk. doubling each year. It is also rapidly becoming the universal medium for information storage, perhaps because the cost of magnetic storage is dropping rapidly. As of fall 2000, a gigabyte of storage cost less than $10, and experts predict that this price will drop to $1 by 2005.

The study also deflated dreams of a paperless office. To wit, the amount of information stored on paper, including books, journals, and office documents, increased to 43 percent in 2002 compared to 1999.

Some of the survey's other interesting findings include:

* The world produces between 1 and 2 exabytes of unique information annually--roughly 250 megabytes for every man, woman, and child on earth.

* Printed documents of all kinds comprise only .003 percent of the total.

* Soon it will be technologically possible for an average person to access virtually all recorded information.

* Original documents created by office workers comprise more than 80 percent of all paper documents.

* Digital information production is the largest and most rapidly growing. Optical and digital magnetic storage shipments are doubling each year.

* The United States produces about 25 percent of all textual information and at least half the content stored on magnetic media.

* In 2000, the World Wide Web consisted of about 21 terabytes One trillion bytes. Also TB, Tbyte and T-byte.

* About 500 times as much e-mail is being produced annually as the stock of Web pages. About 610 billion e-mails are sent each year, compared to 2.1 billion static Web pages See static HTML..
