Computer Basics 5: How To Measure Data Size

How the size/amount of data is measured, starting from a bit and going all the way up to a petabyte.
Today we're going to be talking about Data Size.
The smallest size we can have is called a bit.
That bit can only be a 1 or a 0, and that goes back go binary we've been talking about.
After that, we've got a Nibble, which is 4 bits, which isn't common but it's adorable.
The Byte, which is very common, is 8 bits.
A lot of things are expressed in binary Bytes.
After we get past the tiny bit and the small Byte, we get bigger really fast.
The next step up is a Kilobyte, 1024 Bytes, or 1,048,576 bits.
After that there's Megabyte, or 1024 Bytes to the power of two.
Then it's Gigabyte, 1024 Bytes to the power of three; Terabyte, 1024 Bytes to the power of 4, and Petabyte, 1024 to the power of 5.
These get much bigger really quickly!

Where have you been all my life. Thanks for these awesome videos!

Amazing teacher and lessons, I hope you will keep going on

she just gets prettier in every video.

At 1:03, the sizes are expressed in base two. So the sizes should per IEC standard should be: kibibyte, mebibyte, gibibyte, tebibyte and pebibyte.

So, I guess when we communicate with the computer through code we are feeding it nibbles and bits.

[kvelez]

I didn't know about nibbles, thank you.

Where would one experience the PB being used??

[adnjoo]

Actually a Petabyte is 1, 125, 899, 906, 842, 624 bytes

i've always wondered why data sizes are 1024 not for example 1000, can anyone explain why?

[gregstyles]

1024 is a kibibyte not a kilobyte, express the units in 2^10 2^20 2^30 not 1024^x

What is the actual size of bit.? I understand Binary. I would like to know it, in measurement.

I want from basic it means from c, c++pls make a video

[vinayvikey]

If u have done pls keep the link in comment

[NativeVsColonial]

What about the ZB?








Zettabyte sobs in a corner :'(

[shrutisingh]

i swear- she was here for another reason LMFAO

[joelsingh]

What's your name ma'am
Where are you from?
