    This is cool. When the CD-Rom was first introduced, I purchased the console for my children. I had two boys and a stepdaughter. One son is dead, and the stepdaughter attempted to murder her grandfather with her boyfriends help. She is no longer welcome anywhere near me. Anyway, I would purchase this. I am a fan of state of the art technology. Good luck...

    Sir i don't understand the last part where you get the bytes Please help😢😢😢😢

    • @OALevelsComputer
      @OALevelsComputer 2 หลายเดือนก่อน

      The bytes are obtained through a process of Run-Length Encoding (RLE), where repeated values are compressed by storing the value and its frequency. For example, a sequence like "2 0 0 0" indicates the value 0 (black color) repeated 2 times. In this way, the RLE representation stores only the count and value, reducing data size. Remember each pixel is stored as 3 bytes (RGB), so for an 8x8 image, that's 192 bytes. 1) The image's repeated color values are encoded as pairs of (count, value), reducing the size significantly. 2) Compressed data size: After encoding, the compressed file is 92 bytes, achieving a 52% reduction in size. still dont understand? whatsapp me +92-332-3076658
