Give two reasons why a compiler is typically broken down into passes (or phases) and indicate a typical set of passes and the data structures passed between them. [4 marks] (b) nd run within many browsers, might differ from that of compiling an application and running it multiple times on a single machine.sign a protocol (including message formats) for distributing this information across the network. [10 marks] (c) Give a bound on the total amount of information which is transmitted to ensure that every node acquires complete topology information. [5 marks] 2 CST.98.6.3 4 Computer Graphics and Image a rectangular array of square pixels. The panel is tinted with a special ink which allows each pixel to range from totally transparent to transmitting only the colour of the ink. Each pixel has an 8-bit value. For example, if the ink is blue then a pixel value of 0 would be totally transparent, 255 totally blue (only blue light transmitted) and 100 a light blue. light light diffuser panel viewer The inventor has recently found that he can make the special ink in any colour he likes, but that each panel can be tinted with only one of these colours. He proposes to use three inks in three panels to make a 24-bit colour display: a red-tinted panel, a green-tinted panel and a blue-tinted panel will be stacked up to make a full-colour display (see picture). A value of (0, 0, 0) will thus be white (transparent), (255, 0, 0) red and (255, 255, 255) black. light light diffuser viewer red panel green panel blue panel Explain why this will not work. [4 marks] Modify the three-panel design so that it will work. [3 marks] In common with other 24-bit "full-colour". Text-based play: The main() method of GameEngine class should support a text-based game play in the console.Start by drawing one or two paper sketches GUI plan to build. Take a photo of each sketch, as will need to include these as well 1 Compiler Construction 2. Class Relationships: engine needs to include several Java classes, with some association/composition relationships between them, and if possible, some inheritance/interface usage. Think about where can best use these Java features.Question 3: Game GUI: The goal of this stage is to use JavaFX to add an elegant and fully functional GUI to the game so that it can more easily be played on desktop computers. GUI should have the following features:

event-handling of mouse events, including buttons for starting game and moving up/down/left/right;

display of bitmap images (recommend use some large images for the background whole game, and use some small images for different items/cells in the map, so that the game looks professional and entertaining);

multiple panels, with a main gaming panel to display the game, plus one or more panels around the edges to display game options, score information, and control and help buttons etc.;

a clean separation between the back-end (game engine) and front-end (GUI) classes using different Java package names, as described above;
