Understanding information measures

Bytes (8 bits)
1 byte – one character
10 bytes – one word
100 bytes – one sentence

Kilobyte (1000^1 bytes)
1 Kilobyte – one paragraph
2 Kilobytes – typewritten page
10 Kilobytes – page out of an excyclopedia
100 Kilobytes – a low-resolution photo

Megabyte (1000^2 bytes)
1 Megabyte – 1 thick book (500 pages)
2 Megabytes – a high-resolution photo or one MP3 file
5 Megabytes – complete works of Shakespeare
100 Megabytes – a mettar of books on a shelf
700 Megabytes – CD-ROM

Gigabyte (1000^3 bytes)
1 Gigabyte – 500,000 pages or 1000 thick books
2 Gigabytes – 20 metters of books on a shelf
20 Gigabytes – a collection of the works of Beethoven
50 Gigabytes – library floor of books on shelves

Terabyte (1000^4 bytes)
1 Terabyte – one million thick books; 50,000 trees made into paper and printed
2 Terabytes – academic research library
3 Terabytes – 1000 hours of good quality video
10 Terabytes – printed collection of the US Library of Congress

Petabyte (1000^5 bytes)
1 Petabyte – 180 Libraries of Congress; 500 billion pages of standard printed text
2 Petabytes – all US academic research libraries
200 Petabytes – all printed materials in the world

Exabyte (1000^6 bytes)
1 Exabyte – 180 thousand Libraries of Congress
1 Exabyte – 50,000 years’ worth of DVD-quality video
5 Exabytes – All words ever spoken by human beings

Zettabyte (1000^7 bytes)
1 Zetabyte – 180 million Libraries of Congress
1.2 Zetabytes – the amount of all data created worldwide in 2010

Yottabyte (1000^8 bytes)
1 Yottabyte – 180 billion Libraries of Congress

Brontobyte (1000^9 bytes)

Geophbyte (1000^10 bytes)

The Library of Congress in Washington D.C., US, is one of the world’s largest libraries with over 28 million volumes. The numbers listed above are based on the assumption that the average book has 200 pages.

Knowledge economy and information

A knowledge based economy places emphasis on generating knowledge assets such as codified human expertise, research and development (R&D), intellectual, financial, health and education services. In the knowledge economy, markets are increasingly competitive and innovation is in constant demand. Fast assimilation of knowledge is required, while knowledge workers have less and less time to acquire it. They need to find and attain huge quantities of information efficiently and effectively.

So what is the role of information and information providers? Information found has to be instantly available and immediately usable. There is no time for conducting complex searches or waiting for information delivery. Instant retrieval, instant delivery, instant use are the key guidelines to be followed by successful information providers. Once acquired, information has to be quickly transformed into new knowledge adding instant value to specific projects, products and services.

Today, instant information creates targeted knowledge, which means success!

Information glut

Zettabyte of information – a new nerdy term!

It is a known fact that the volume of information that we encounter during a single day in the 21st century is more than a person received in a lifetime at the beginning of the 20th century. We all live in times when the amount of available information is so overwhelming that we are unable to effectively process and utilize it.

It is a product of the high-tech age and it comes from all sources including internet, TV, radio, newspapers, magazines, regular mail, e-mail, billboards, and many other types of information.

According to recent studies the size of the information universe is 800,000 petabytes. Each petabyte is a million gigabytes, or the equivalent of 1,000 one-terabyte hard drives. If you stored all of this data on DVDs the stack would reach from the Earth to the moon and back.

We should also keep in mind that a terabyte could hold about 3.6 million 300 Kilobyte images or about 300 hours of good quality video. A terabyte could hold 1,000 copies of the Encyclopedia Britannica. Ten Terabytes could hold the printed collection of the Library of Congress.

Lets remind ourselves:

· 1000 Megabytes = 1 Gigabyte
· 1000 Gigabytes = 1 Terabyte
· 1000 Terabytes = 1 Petabyte
· 1000 Petabytes = 1 Exabyte
· 1000 Exabytes = 1 Zettabyte

It is predicted that next year’s total will reach 1.2 million Petabytes, or 1.2 Zettabytes.

Welcome to the era of the Zettabyte, which is equivalent to 1 million Petabytes, or 1,000,000,000,000,000,000,000 bytes.

Zettabyte is a new term created to accommodate the exponential increase of data creation, inspired by social networking, image, and video files, VOIP, and the wealth of new kinds of devices on which information bytes can be stored.

We should remember this new term Zettabyte since it will be with us soon, and it will remain for long. But not for too long since Yottabyte (1000 Zettabytes) is just around the corner!

Welcome to Intellobics!

Intellobics is a form of mental exercise designed to enhance cognitive abilities, improve thinking, foster mind capabilities, and lessen the impact of aging on our mind!

This blog offers some thoughts about four great questions:

  • Why should we learn new things?
    Man’s mind, once stretched by a new idea, never regains its original dimensions.
  • What should we learn?
    Even the wisest mind has something yet to learn.
  • When should we learn?
    A day when you did not learn something is a lost day.
  • How much should we learn?
    Strange how much you got to know before you know how little you know.

Enjoy and never stop learning!
