Bit-mapped graphic files size is calculated by multiplying the number of pixels by the color depth per pixel measured in bits or bytes. Increasing image resolution or color depth improves quality but also increases file size. Techniques like dithering, anti-aliasing, and re-sampling can help reduce artifacts and enhance image quality. Lossy compression can significantly reduce file size with minimal impact on quality depending on the compression rate used. Graphics cards process and store images, converting digital signals to analog for display via a DAC. The GPU on the card generates images faster than the CPU for gaming and advanced graphics. CRT monitors were bulkier than modern LCD/TFT screens but cost less.
