Why 1 GB is not equal to 1000 or 1050 MB but 1024 MB?

 1 GB equals 1000 MB. That is the truth.

Where GB means gigabyte. MB is a megabyte.Wait, wait, don't come to kill. Let me tell you a little.

Well, have you noticed somewhere that GiB or MiB is given as digital storage size. You either read gigabytes or megabytes. In fact, it is Gibbyte and Mbibyte, gradually.

This time the relationship between these two signs.

1 GiB = 1024 MiB.

Similarly, 1 MiB = 1024 KiB. KiB is the KiB byte.


Now if you think why 1 GiB = 1024 MiB, then it can be said that it is a calculation formality.

Since 10³ = 1000 is captured as "kilo" in the metric system, 1000 bytes (B) are captured as 1 kilobyte (KB) to match it.

That is 1KB = 1000 Byte

1 MB = 1000 KB = 1000000 Byte

But since the computer understands only 2 digits, 0 and 1, all the values ​​are expressed as the power of 2. KiB or MiB or GiB has been given separately by the International Electrotechnical Commission - without confusing this calculation with the metric method.

That is 1KiB = 1024 B

1 MiB = 1024 KiB = 1024 * 1024 B = 1048576 Byte


Let's see another example:

A computer but does not understand language like humans. The language he understands is called binary code. There are only two letters 1 and 0 in this language. All the work of the computer is done by arranging these two letters in different ways. But the reason for such bizarre language?

The computer is powered by electricity, so if there is electricity in a circuit on its chip, that is, if it is on, then it is called 1, and if it has no electrical connection, that is, if the circuit is off, then it is called 0. These 1 and 0 are created through different logic gates and the computer code is executed in a mixture of all these gates.

Then a bit that is the smallest unit of memory in a computer will have 1 or 0 in it. So its size will be 2. After that, as we increase the number of memory, it will increase in proportion to this 2nd.


22 = 4


23 = 8


24 = 16


25 = 32


26 = 64


27 = 128


28 = 256


29 = 512


210 = 1024


We see 32 GB, 64 GB or 128 GB storage in this mobile. And in the metric system, at a multiple of 10 (I don't know its Bengali) everything increases to 210 MB = 1024 MB = 1 GB.

So simply because of the predominance of binary code in computers, we see 1024 MB, not 1000 MB or 1050 MB.

What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant ?

Today we talk about What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant .I never like huge introduction about any topic . I always like very shortly introduce any-things to my viewers without any-type boring .So let's began the leanrning :- 1. Decide in advance how many devices you will use. 2. Decide how much space you need coverage. 3. Understand the structure of your home. WiFi signals become weak to penetrate the walls. That is why good coverage is not available. If you have a lot of walls in your house and you want to get coverage in the whole house, then you need a router with high power and wall penetration feature. 4. Decide what features you need in addition to the internet connection. Such as: - 4.1 3G 4G Modem Support- There are many routers that can use the modem. Those routers have a USB port and a one port so that broadband lines can be used. But remember that the modem must have the ability to auto-connect. Not...

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
