**Self Assessment, Mid Term:** **Chapter 1 questions:\ ** What is the Von Neumann Model and what are the parts? The Von Neumann Model is the fundamental computer design that describes the structure and organization. The parts are input unit, central processing unit, control unit, algorithmic unit, memory unit, output unit. How does the binary number system work? It works by storing data into 0s or 1s and turns them on or off. What are the main properties of digital media? Procedural (programable), Participatory (Interactive), Spatial (Multi functional), Encyclopedic (High-storage), Distributed (Location Aware). **Chapter 2 questions:** What is a screen? A screen consists of small points called pixels. What is screen-resolution? It is the two-dimensional size of the screen in terms of pixels. What is aspect ratio? It is the width to the height. What is color depth? Color is created and displayed using the combination of red, green, and blue. What is a pixel? A pixel is a small point on the screen. What are 8-bits and 24-bit color values?\ 8 bits store up to 256 color combinations, but 24 bits can store up to 16 million color combinations. In 24 bits, there are 8 bits for each RGB color. How are BMP, JPG, and Gif file formats different? BMP has no compression. JPEG is true color but can have different levels of compression. PNG has lossless compression and allows transparency. GIF has only one byte per character so smaller in file, but has animation. How does a coordinate system work in computer graphics? The coordinate system works in computer graphics by using X and Y values to position, manipulate and render objects that are on the screen. How does a blur filter work? The blur filter works by compressing it's neighbouring pixels and changes its value. What is the difference between vector and raster graphics? The difference between Vector and Raster graphics is that Vector graphics does not lose any quality when zooming in a photo while Raster graphics loses quality when zooming in. What is the difference between of object and world coordinate systems? The object coordinate system defines the object in a positive relative to its own local center while the world coordinate system defines the object's position relative to a fixed global origin. **Chapter 3 Questions:** What are frames and FPS in an animation?\ Frames are a collection of images. FPs in an animation is how fast the motion is. How does Cel animation work? Cel animation works by separating layers for characters, objects, and background then combines them into one. What is a sprite? A sprite is a single image. What is a keyframe and what is special about keyframe animation? A keyframe animation are frames that are generated by a computer software. It's special because it reduces the amount of time to work on a project. Explain the process of motion capture. When do we need it? Motion capture captures the motion of a human in order to design characters for games, movies, and animations. What is procedural animation? How is it similar to and different from keyframing?\ Procedural animation is animation that has been generated by a computer software using mathematical calculations. It is different from keyframing because it follows the fundamental laws of math and physics. **Chapter 4 questions:** What are the differences and relations between the web and the internet? The internet is a global network of interconnected computers that allows data to be sent and connect various networks while a web is a collection of information and resources that can be accessed through the internet using web browsers. How does a web server work? 1. When a user enters a URL in their browser the browsers sends an HTTP request to the server where the website is hosted. 2. The server receives the request and then locates the relevant file and if necessary processes it. 3. Once it is processed, the server then sends back an HTTP response for the page which the browser renders for the user. What is a markup language? A text that describes formatting and structure of output content using specific signs. How do HTML elements work? HTML elements work by describing a function to be displayed on the web. How do we include images/audio/video in HTML? \ \ \ \ \ \ What are the basic page formatting elements in standard HTML? \ \ \ \ this is my review \ \ \ let us start \ \ \ now we can use the body element here \ \ this is so fun \ \ \ **Chapter 5 questions:\ ** What are UI and UX, and how are they related?\ User Interface is all the elements that users are able to interact with the system/website. User experience is how friendly the system/website is, and how accessible it is. They are related because it is through user interface that user experience emerges and those interactions make the overall journey for the users. What are the elements of design thinking? Empathize, define, Idea cocreation, prototype, test What are common parts of web design/development process? The common parts of web design are clarity of purpose, content quality, visual appeal, performance, device optimization, security, and usability. How is web production similar to and different from other media production? In a way, it is similar to other media production because they follow the same design process but the difference is that web production is always changing even though there are many versions of the final product. For instance, a company can always make a website and change it in the future to make it user friendly and inclusive to people with disabilities whereas some media production, once they are finalized, cannot be changed. What are common inclusion issues in technology design? 1. Low contrast between text and background 2. No link description 3. No skip to content link 4. No structured tables. What are AODA and WCAG? AODA stands for Accessibility for Ontario Disabilities Act that is a law to define and enforce accessibility standards. WCAG Is Web Content Accessibility Guidelines to make content accessible for people with disabilities.
