Q : How does a word get displayed and more complicated instructions operations?
A : The number 65 refers to "A" in ASCII, and the computer uses this to look up the corresponding glyph (shape) in the font file, which contains instructions (like vector curves or pixel grids) to draw the letter "A" on the screen. In a lower-level environment without font files, letters are represented using bitmap fonts. Each character is mapped to a grid of pixels (e.g., a 5x7 grid). The system retrieves this grid, maps the pixels, and renders the letter directly on the screen. For example A:
