What is GiGabyte and its History – Difference Between GB and MB

What is GiGabyte Size

Do you know what Gigabyte is? If yes, then it is a perfect thing because it is a fundamental question. But even if your answer is no, then there is nothing to be sad about because today we will get all the information related to Gigabyte in What is Gigabyte.

If you use a computer or think about how a new and good computer will be, you must have thought about how much memory should be in your research and such a situation; you must have heard the word GB (Gigabyte). Will happen.

Because memory size (or it Also called RAM Size) often 4GB, 8GB, up to 16GB is considered standard. This Gigabyte is also a unit of digital information storage.

Apart from this, the matter of 500GB, 1TB, 2TB also arises in the size of Hard Disk. These units are measured according to digital information storage size. Due to this, it is essential to know about all these units because we need these memory size units a lot while calculating memory size.

So today I thought, why should you be provided complete information about Gigabyte so that you people will not have any problem understanding it. So without delay, let’s start and know what this gigabyte is.

What is Gigabyte

A gigabyte is 10 power 9 (10 ^ 9) or 1,000,000,000 bytes. One gigabyte (abbreviated to “GB”) is the same as 1,000 megabytes and comes before the terabyte unit in the measurement.

Technically 1 gigabyte is 1,000,000,000 bytes, but in some cases, gigabytes are also called synonymously gibibytes, which contain 1,073,741,824 bytes ( 1024 x 1,024 x 1,024 bytes ).

Gigabytes are called ” gigs ” in short and are often measured according to a storage capacity. For example, a standard DVD of about 4.7 gigabytes hold data.

An SSD up to 256 GB, and some hard drive storage capacity is also up to 750 GB. Storage devices that store 1,000 GB of data or more are typically measured in terabytes.

RAM is often measured in gigabytes. For example, a desktop computer has 16 GB of system RAM and 2 GB of video RAM.

The tablet requires only 1 GB of system RAM to run as the portable apps in use do not typically require much memory, as in desktop applications.

What is the history of Gigabyte?

This term ” byte ” is initially referred to with the smallest amount of data that a computer can ” bite ” or ” chew “. That is, I could handle it at one time.

It is a deliberately spelt byte, in which ay is spun to remove confusion so that it does not have to be confused with another computing term: bit. The Giga is a prefix that denotes 1 billion.

Measurements of data capacity that are larger than gigabyte:

  • One terabyte is equal to 1,024 gigabytes.
  • One petabyte is equal to 1,048,576 gigabytes.
  • 1 exabyte is equal to 1,073,741,824 gigabytes.

Measurements of data capacity which are smaller than gigabyte:

  • 1 megabyte — 1,024 megabytes equal a gigabyte.
  • 1 kilobyte — 1,048,576 kilobytes equal a gigabyte.
  • One byte — 1,073,741,824 bytes equal a gigabyte.

Why is Pen Drive 8Gb 16GB 32GB?

Often you will see that in the market or Online in Pen Drive 8Gb, L6Gb, 32Gb like observes the same pattern because it is designed in this way only.

One thing you have to understand is that memory allocation is always considered, keeping the power of 2 in mind . for example :

Two raised to 3 is 8

Two raised to 4 is 16

Similarly, two raised to 5 is 32, and it goes on like this.

This does not apply only to Pendrive. Instead, the pattern of representing memory is the same in all components that hold memory.

And together, their size is also similar. This section also includes Ram, Graphics card, HDD and Download speed standards.

What do MB and GB mean?

Before understanding the meaning of MB and GB, let’s know the importance of all basic units.

Bit: Computers deals in binary digits or bits (called short). A bit is either 0 or 1, meaning it is either On or Off.

Byte: 1 byte is eight binary digits, such as 1111001.

Kilobyte (KB): the youngest file size is stored in the smartphone; the size of tablet and PC is typically four kilobytes (4KB).

There are 1024 bytes in 1 kilobyte. Therefore 1KB means 1024 x 8 = 8192 binary digits.

Megabyte (MB): 1024KB is similar to a megabyte (MB).

Gigabyte (GB): Likewise, 1 gigabyte (GB) has 1024MB.

Terabyte (TB): Similarly, 1 terabyte (TB) has 1024GB.

Hard Drive or any memory devices have lower capacity compared to their advertised memory?

Hard drive manufacturers have already done such work in their system in which they often do rounding down to make things easier (and provide less storage space to users like us).

This means 1000 bytes = 1 kilobyte and 1000 kilobytes = 1MB. Again, 1000MB = 1GB and 1000GB = 1TB.

In Windows, however, things are different, and they follow the 1024 rule, which means that they show a 250GB hard drive as 232GB and a 1TB drive as 931GB.

By this, you must have understood why the capacity of hard drives is more minor than advertising them.

For example, 1TB hard drive can store 1,000,000,000,000 bytes. Which if you divide by 1024, then you will get 976,562,500KB. Then if you Divide it again from 1024, you will get 953,674.3MB.

Finally, if you divide it to get 1024 gigabytes, then, in the end, you will only get 931.32GB.

How to visualise 1 Gigabyte?

A standard DVD can hold about 4.7 GB of data. While a typical about 16 GB random in laptop or desktop computer access memory is

In this case, if you have to visualise 1-gigabyte, then it is similar:

  • With 250 downloaded songs;
  • 6,180 emails with sent and received;
  • 250 10 – megapixel with photos;
  • 50,000 average emails with no attachments;
  • 3,333 average emails with a standard attachment;
  • With 5 hours of classic definition movie
  • 353 one-minute With YouTube videos.

From this information, you may be able to visualise how much memory of 1 Gigabyte is there.


I hope that I have given you complete information about Gigabyte, and I hope you all understand what Gigabyte is.
