About Unit in Computer World

Posted by Otak Komputer on Tuesday, 10 November 2009

Bit is the smallest unit of data that used a computer. Bit used to represent two kinds of data or information, such as yes or no, 0 or 1. The data can be found daily has many forms, such as: sound, letters, numbers, photographs, images, movies and so on.

Each number 0 and 1 called Bit (Binary Digit). Binary word-which means two or a pair, taken from a Binary Number System (Binary Numbers System). Binary Number System is one of the number system used by computers that only use two numbers to represent the symbol of a scale value of 0 and 1. In contrast to humans who use the decimal system which consists of 10 symbols numbers: 0-9.

Eight Bits equal 1 Byte. Byte represent 256 units of information, such as numbers or a combination of numbers and letters. 1 Byte approximately equal to one character.

1000 Byte (1024 Byte exact definition depends on the unit used) is equal to 1 Kilobyte.

1000 Kilobytes equal to 1 Megabyte. In the early days of computing world, 1 Megabyte is the amount of data is very large. But on this day the computer with a 80 Gigabyte hard drives were common, 1 Megabyte no longer regarded as a very large size. An old floppy disk size 3 1 / 2 inch can hold 1.44 Megabytes or equal to the charge of a small notebook. 100 Megabytes might hold a number of free.

1000 Megabytes approximately equal dengan1 Gigabyte. 1 Gigabyte is a very common term used today when talking about the capacity of a floppy disk or drive storage. 1 Gigabyte of data is almost equal to twice the amount of data that can accommodate a CD-ROM, or a thousand-fold the capacity of a floppy 3 1 / 2 inches. 1 Gigabyte could hold the contents of the entire book on the shelf for ten yards. 100 Gigabyte could hold the contents of one floor of the library contains an academic journal.

1000 Gigabyte Terabyte equals 1 trillion or 1 Byte. For now Terabyte not include the usual term used. Just a picture, can hold 1 Terabyte 3.6 million images or approximately 300 hours of very good footage. Able to accommodate 1 Terabyte 1000 Encyclopedia Britannica coffee.

1000 Terabyte equals one million petabytes, or one Gigabyte. It's hard to imagine the large amount of data that can be accommodated by one petabytes. One can store petabytes of content than twenty million pieces filing cabinet (storage cupboard) four-door with a full load, or five hundred billion pieces of text that has been printed. Meanwhile, to save the data with the amount we need five hundred million ordinary floppy disk.

1000 petabytes is more or less equal to one billion exabytes, or one Gigabyte. Not so much a comparison unit of measure that can describe one exabytes. As to say that 5 exabytes equal to the sum of all the words ever spoken man.

1000 exabytes is approximately equal to one Zettabyte. Until now there has been no unit of measure that can describe a Zettabyte, which clearly we need a number one with lots of zeros.

1000 Zettabyte equal to one Yottabyte. Again, very difficult to describe the capacity of a single Yottabyte.

1000 Yottabyte equal to one Brontobyte. The only thing that can be said to describe a Brontobyte is a number one followed by 27 zeros behind.

Here's a simple diagram of the data quantity unit of measure:

* 1 Bit = Binary Digit
* 8 Bits = 1 Byte
* 1000 Bytes = 1 Kilobyte
* 1000 kilobytes = 1 Megabyte
* 1000 Megabytes = 1 Gigabyte
* 1000 Gigabytes = 1 Terabyte
* 1000 terabytes = 1 petabytes
* 1000 Petabytes = 1 exabytes
* 1000 Exabytes = 1 Zettabyte
* 1000 Zettabytes = 1 Yottabyte
* 1000 Yottabytes = 1 Brontobyte
