The amount of memory 1 GB - is how much?

With the development of computer technology, new terms are emerging every year. Many often use the word "gigabyte", but do not fully understand the meaning of this concept, because of what they can not answer the question about how much memory is in 1 GB - this is how much.

What is gigabyte?

Before you deal with the question "1 GB is a lot or a little," you need to understand the essence of the unit of memory. In the work of most electronic devices, the processing of pulses of electric current is used. This method allows you to process a large amount of information in a short time and has only two values - "Yes" or "No". This minimal informative unit is called a bit.

With the help of bits in the computer all the necessary data is set - texts, pictures, sound and so on. To increase the processing speed of pulses, it was decided to split the entire stream into groups - one set of 8 bits of steel was called a byte. With the development of technology, it was required to work with an increasing amount of data, which resulted in the appearance of new divisions into larger groups.

To simplify the process of understanding the number of bits in a given value, it was decided to use prefixes from the SI unit system. As a result, kilobits, megabytes, and other memory sizes appeared. But, according to a unified SI system, the value of each prefix was a multiplier in the form of a number 10 to a certain extent. And computer information, due to its binary nature, is represented in the form of a deuce to some extent. Because of this, with a precise definition of a smaller value, one often encounters a disagreement. Despite the existing contradictions in the exact determination of the number of bits, the differences in the values for consoles with a small difference are insignificant. So, according to these calculations, 1 kilobyte contains not 1000 bytes, but 2 ¹⁰ - 1024 bytes.

How many in one gigabyte?

The prefix "giga" according to the SI system means 10 ⁹ , that is 1 billion. The nearest prefix to "giga" is "mega", which is 10 ³ times smaller. But on the territory of most countries of the world, including Russia, the exact number of bytes is determined using the deuce to the n-th power, so the answer to the question about how many MB in 1 GB is 1024.

Continuing to consider smaller values, instead of multiplying by 1000, further calculations are performed using 2 to 10 power. Thus, 1 GB is 1024 * 1024 = 1048576 kilobytes or 1024 ³ = 1,073,741,824 bytes. To get the number of bits in 1 GB, you need to multiply the resulting byte by 8, getting a total of a little more than a billion.

The largest value of memory capacity

The ruler for measuring memory units has long surpassed the prefix "giga" by several steps. At the moment, the most important amount of information is one iotaabyte. In comparison with 1 GB it is 10 ¹⁵ times more or, according to the Russian definition, 20 ⁵⁰ times.

Between iotabyte and gigabyte there are 4 more volume definitions, each of which reduces the degree of 10 by three when using the SI system, or, in the binary case, the power of two is 10.

Gigabyte - is it a lot or a little?

Every day in the world, various calculations are made, for storage of a total volume of which 1 Gb is small. This value hardly approaches even for work of one user - now volumes of operative memory in which constantly stored data are stored, already in times exceed this value. The size of one movie in an average quality of about an hour takes a little more than a gigabyte, which is why the very value of memory size has become relatively small, despite the great importance when considering byte-byte.

Flash drives with a capacity of 1 GB are also remnants of the past, which are already difficult to find. Now for the transfer of information using more voluminous devices, including external hard drives, the volume of which can reach tens of terabytes, which is 1000 times more gigabytes.
