This graphical user interface—or GUI, pronounced “gooey”—was facilitated by another concept pioneered at Xerox PARC: bitmapping. Until then, most computers were character-based. You would type a character on a keyboard, and the computer would generate that character on the screen, usually in glowing greenish phosphor against a dark background. Since there were a limited number of letters, numerals, and symbols, it didn’t take a whole lot of computer code or processing power to accomplish this. In a bitmap system, on the other hand, each and every pixel on the screen is controlled by bits in the computer’s memory. To render something on the screen, such as a letter, the computer has to tell each pixel to be light or dark or, in the case of color displays, what color to be. This uses a lot of computing power, but it permits gorgeous graphics, fonts, and gee-whiz screen displays.define sterilisation and disinfection“Then he is in some trouble?”baby safe disinfectant wipesSubsequently the Company appears to be adopting a hostile posture toward me and the new venture.
