Your presentation is good and energetic but slightly misleading. In reality, bitmaps aren't stored like this-each pixel is not represented with a letter from the Latin alphabet. Instead, each pixel has a colour which is defined by a string of bits, and the length of the string of bits determines the colour depth of the image. It's clear from the comments that you have confused a number of people about the method in which the images are stored. Instead of saying that each pixel is stored with a letter, you could have said that: In the black-and-white image of a cup, each pixel is stored as a 1 or a 0. If you have four colours, each pixel is stored with two bits (00, 01, 10, or 11), thereby the image has a colour depth of two bits. You've explained the use of binary and transistors in computers, but transistors don't "store" 1s and 0s. They simply allow or disallow current to flow through them. Also, Unicode is not used for storing images. Unicode is a standard for encoding symbols and letters from other languages and writing systems. I don't want to sound condescending, and correct me if I have made any mistakes; I understand this video is meant to be simple, but perhaps you've made it "too" simple.
Looks like Satan claiming to be the god of math. 'x' for Antichrist or mark. 'x' is also the middle Hebrew variant of the letter which Christ claimed to be "aleph and the tav." Pretty interesting.
Each pixel varies in color, including pixels that will look like they have a gradient shading. What happens is that each one of those shades will have a number code that refers to the 1s and 0's. Each one of these shades recreate the picture. The more complex and the more pixes, the more defined the picture will be.
He is a good teacher and I loved the tutorial. I want to add something, computer stores bits(0s and 1s) in flip-flops not in transistors. Another thing is that flip-flops are actually combination of transistors and some other electronic components. A single transistor can not represent whole flip-flop.
Bro... Transistor doesn't store bits... It only use for processing bits..... Bits stored into capacitors(dynamic ram) or flip flop(static ram)... N microprocessor doesn't store anything.... It only use for processing... Sometime it holds value in its registers.
Wonderful boss. What a genius explanation it was! Your have cleared my one of the doubts which was in my mind for years. Thanks a lot . Please make some more videos like this.
If every thing stored as 1n0s so what's difference between image file stored as 1n0s and mp3 file stored as 1n0s?? Or why my image file isn't playing while I rewrite it's extension as .Mp3 ?? Does anything else also stored in a image binary file to specify it's extension??
Answer: Yeah, actually music is stored in 1 0, because the music is a vibration for a thingie turning off and on, and the movie too, videos are combinations of photos, then u add music, ta daa
What if the computer wants to store gray and green at the different pixels, it will Code the alphabet to "G", then this G will convert to the one to one mapping, and then how will it recognize that the particular G belongs to gray or green?
Each pixel represents a color and each color has a different color code (say gray-50, green-51). color code gets converted to binary format (into1s or 0s) .
How is so much information (music, audios, pictures, videos etc) stored inside such tiny micro sd cards? And how is everything stored as 1's and 0's? When would you know one set of numbers ended and another began? And how do these numbers convert into sound?
I dont understand why they don't just store 3 images, with each one being a direct bitmap in each primary colour (RGB). (Ex: red=1, black=0 for the first image, etc.) Won't the information be much more compact?
I already knew this but I still watched If u liked this , u would love crash course computer science 10 times more on RU-vid , its one of most entertaining courses on RU-vid
i think computers store images by making every pixel a hex color value or something or maybe like a "channel" stores an amount of red, green, or blue for each pixel
The logic of 1s and 0s is pretty simple. 1 stands for true, 0 stands for false. Starting from left to right increasing the exponent of 2 (starting from 0) and adding the true members together. Any number can be obtained like this.
I'm sorry to say this, but his explanation is rather bad. - The most basic form of picture for a computer is a bitmap. Each colour in a picture is defined by values from 0 to 255 in a red, green and blue hue (matching our eyes). 0 to 255 is because that's how bits works in a computer, 00000000 to 11111111. So each pixel in the image simply has three values from 0 to 255 to tell how much red, green and blue that pixel is. He's right about you simply going through the image pixel by pixel. Because of this, bitmaps are huge in file size and not recommended to use. Instead we use a format called PNG, which uses lossless compression, which is much more complicated to explain.
