Then pick someone else to explain how DPI is relevant, Representing Data 5 - Explain, with examples on the board, why Vector images are infinitely scalable, General Theory 1 - Explain the role of the BIOS in the ongoing operation of the computer, General Theory 2 - Explain if the Motherboard uses serial or parallel communication, and then pick someone else in the class to say 'why' that method is used, General Theory 3 - Explain why Clock Speed is relevant to the speed of the computer, General Theory 4 - Explain either why it IS true, or ISN'T true, that quad-core computers are always faster than dual-core computers, General Theory 5 - Explain the concept and use of Virtual Memory, Number Systems 1 - True or False, with explanation: A 16-bit word can store twice the amount of data than an 8-bit word, Number Systems 2 - On the board, count from zero to decimal 30, in base-7, Number Systems 3 - True or False: Hexadecimal 77 is greater than decimal 130. Show calculations on the board, Number Systems 4 - Explain, with example, why when I called my wife "Babe", she instantly said 48,706 Mrs Ibbotson, Number Systems 5 - True or False: (with examples) FADED in Hex is equivalent to 64,222, Number Systems 6 - Using the board, show how Christmas Day (Dec 25) equals Halloween (Oct 31) ...octal is base-8), Data Theory 1 - Explain what lossless compression is, and one example of HOW it works, Data Theory 2 - Explain, using an example, how Lossy compression might reduce the size of a file, Data Transmission 1 - Explain, with an example, the principle of Packet Switching, Data Transmission 2 - State THREE things that would be in each packet, Data Transmission 3 - Explain the role of the Router in data transmission, Data Transmission 4 - Explain one method that computers use to detect errors in transmission; THEN pick on one other person to give another method, Data Transmission 6 - True or False (with detailed explanation): A MAC Address and an IP Address are just the same thing, Data Transmission 7 - Explain how VPN technology can mask your geographic location, Data Transmission 5 - Explain the role of the DNS Server when accessing a website, Input/Output 1 - True or False (with detailed explanation either way): An Actuator is an output device, Input/Output 2 - Specify the three types of Touch Screen technology, Programming Theory 1 - Explain, with an example, the use of Check Digits, Programming Theory 2 - Using the board, show a line of (any) code that would make sure a variable is between 25 and 45 inclusive, Programming Theory 3 - Defend Juan, when he says "...but we have to reduce the amount of Verification that we need to do", Programming Theory 4 - Explain, with examples, the difference between a 'Presence Check' and a 'Format Check', Programming Theory 5 - Explain the difference between pseudocode DIV and MOD statements (in python it is "//" and "%" statements), General Theory 6 - Give ONE use of Hexadecimal in computing; then pick one other person to give another use, HTML Programming 1 - Use the board to show the class the line of code that would insert an image called "Fred1.png" into your webpage, HTML Programming 2 - Use the board to show the class a line of code that would link from the words "Click Here", and link to the website "www.bbc.co.uk/sport", Data Transmission 8 - State an advantage of compression, then pick another person to explain a different reason. That person then can select yet another person to pick a 3rd reason, General Theory 6 - Explain how to recover the lost information from a sound file or bitmap inmage that has been compressed by a Lossy compression method!, General Theory 7 - Explain, ideally with examples, how RLE (Run Length Encoding) works, General Theory 8 - Explain how Actuators, Sensors, and Micro-Processors work together to create automated systems,
