The final part of a quick guide to the basics of Python aimed at Key Stage 3 students. Learn about importing turtle to command a moving object. Python - #6 - Turtle Import the Turtle The turtle library stores all of the code to create and move an object called a turtle . The turtle library must be imported into your Python program before you can use it to draw lines, shapes and colours . Create a new Python program and save the file as PythonTurtle . Write import turtle as the first line of code. Basic Shapes The turtle can be controlled by writing how many pixels it should travel forward and the angle it should point left or right . Moving Forwards turtle.forward(100) will move the turtle forward by 100 pixels. turtle.forward(200) will move the turtle forward by 200 pixels. When using the left command or the right command, the turtle won't actually move , but it will rotate by the number of degrees that you state. For example, typing turtle.left(90) will point the turtle upwards . Rotating Left & Right Copy the code to the right to make the turtle draw a square. Then try to make: A Rectangle A Triangle A Pentagon A Hexagon Square Rectangle Triangle Pentagon Hexagon Hint: To work out the angles, divide 360 by the number of sides. Using Loops You can use a for loop to repeat code . This is especially helpfully with intricate shapes with many sides. The code below will print a square but in only 3 lines instead of the 8 lines from task 2. This is the number of times the code underneath will be repeated . Change it to a higher number to repeat it more often . Each line after the 'for num in range' line must be indented . Press the tab key once on your keyboard to indent your code. Task 3 - Copy the code above to make the turtle draw a square using a loop. Then try to make: A Heptagon An Octagon A Circle A Pentagram (5-sided Star) Square Heptagon Octagon Circle Pentagram Hint: To work out the angles, divide 360 by the number of sides. Advanced Features Choose a background colour turtle .bgcolor("red") Choose the line size and colour turtle.pensize(6) turtle.color("green") Fill a shape turtle.color("yellow") turtle.begin_fill() (put your turtle's directions in here) turtle.end_fill() Lift the pen turtle.penup() turtle.pendown() Speed up/Slow down the turtle turtle.speed(speed=10) Change the turtle's appearance turtle.shape("turtle") Other options include "circle" and "arrow". Task 4 - Use the code above to make: A blue square on a red background. A yellow triangle on a pink background. Two different coloured circles - not touching each other. Three different shapes of three different colours - not touching each other. Complex Shapes Use everything that you have learned on this page to help you create more complex shapes. You could try: A Flower A Word (like your name - you will need to use the penup() and pendown() commands. A Christmas tree A Landscape (green ground, blue sky, yellow sun) <<< Selection

The final part of a quick guide to the basics of Python aimed at Key Stage 3 students. Learn about importing turtle to command a moving object. Python - Iteration For Loops Editor Execute A for loop is a count controlled loop. It repeats for a certain number of times as stated in the range brackets. The first number (1) states the number to start on . The second number is an exclusive end . This means it actually finishes on the number before . (11 will end on 10). You need a colon at the end of the loop line . Each line to be repeated must be indented (press the tab key). You can use the loop number within the loop itself. 1. Write a for loop to print your name 8 times . (Count it to double-check it prints eight times.) 2. Use a for loop to print each number between 10 and 50 . 3. Use a for loop from 1 to 10 . Print the 3 times table by multiplying number by 3 underneath the loop. 4. Ask the user to input a whole number (call it num1 ). Write num1 in your range brackets to repeat any message that many times. 5. Ask the user to input a whole number (call it num1 ) and then input a word . Print the word by the number they entered . (Hint: Use num1 in the range.) 6. Delete your code and copy these 3 lines: #Delete the space after the colon for number in range(0,21,2): print(number) What happens when you run this code? 7. Use Q6 to help you print 0 to 100 , going up in 5s . Think about the 3 values you need in the range brackets. 8. Use Q6 to help you print 100 down to 0 , backwards by 1 . Think about the 3 values you need in the range brackets. Tasks While Loops Editor Execute A while loop is a condition controlled loop . While loops repeat as long as the condition is true . As soon as the condition becomes false , the loop will end . 1. Change the program in the editor to repeat the loop while a number is not equal to 33 . 2. Make a new while loop that asks the user to enter a whole number . While the number is less than or equal to 1000 , keep repeating. 3. Make a new while loop for while a colour is not equal to purple (or any colour you want). Ask the user to enter a colour inside of the loop . Don't forget to set colour to "" before you start. 4. Edit your colour program to count how many guesses were made. Make a new variable called count and set it to 0 at the start of the program. Increase it by 1 in the loop, using count = count + 1 . 5. While a total is less than 100 , ask the user to input a decimal number . When it is over 100 , print ‘COMPUTER OVERLOAD’ . You need a variable called total . Increase the total each time with total = total + number . Don't forget to start it at 0 . Tasks != means ‘not equal to ’. The loop below will repeat as long as the password is not equal to “abc123” . Any variable you use in your condition must have a value first . You can’t check for your password if it doesn’t exist. That’s why I have written password = “” , to give password a value before we check it .

Learn about how to perform binary addition and binary shifts. Based on the J277 OCR GCSE Computer Science specification (first taught from 2020 onwards). 2.4b: Binary Addition & Shifts Exam Board: OCR Specification: J277 Watch on YouTube : Binary Addition Overflow Errors Binary Shifts Issues with Shifts Binary Addition Binary addition is a method of adding binary values without having to convert them into denary. How to add binary numbers: What is an overflow error? An overflow error occurs when a binary value is too large to be stored in the bits available . With a byte (8 bits ) the largest number that can be held is 255 . Therefore any sum of two binary numbers that is greater than 255 will result in an overflow error as it is too large to be held in 8 bits . What is binary shift? Binary shift is used to multiply and divide binary numbers . The effect of shifting left is to multiply a binary number. The effect is doubled by each place that is shifted . x The effect of shifting right is to divide a binary number. ÷ Shifting by 1 has an effect of 2 . Shifting by 2 has an effect of 4 . Shifting by 3 has an effect of 8 . For example, shifting left by 2 places has an effect of multiplying by 4 . Another example: Shifting right by 3 places has an effect of diving by 8 . How to shift a binary number: Binary Shifts Watch on YouTube Watch on YouTube Q uesto's Q uestions Binary Addition: 1. Explain what an overflow error is. [ 2 ] 2.

Learn about the benefits and drawbacks of virtualization, as well as about cloud storage and virtual clients. Based on the 2016 OCR Cambridge Technicals Level 3 IT specification. 3.2 - Virtualisation Exam Board: OCR Specification: 2016 - Unit 1 What is virtualisation? Virtualisation is the creation of a virtual version of a device , software , operating system or server . These virtual versions can then be run on a different physical computer system , such as a powerful server . There are many different types of virtualisation . Storage virtualisation combines multiple separate storage devices into acting and appearing like a single , central storage system . Using storage virtualisation improves scalability as further devices can join the storage system if more space is required . It also simplifies the management of storage across the network. Server virtualisation allows one physical server to be divided into and host multiple virtual servers , each running separately . Each virtual server operates independently , handling its own operating system and applications . This allows for resources to be used more effectively and improves the scalability and versatility of the physical server . Client Virtualisation (Virtual Clients) Client virtualisation is when several virtual desktops are run on a single server - think back to the hypervisor from 3.1 . A virtual client is a full desktop environment where the processing happens remotely . For example, where an operating system is managed and hosted centrally but displayed locally on a different computer. These are often known as 'dumb clients ' because the server does the processing for it , meaning it can have minimal resources like a slow processor and little memory / storage . General Benefits & Drawbacks of Virtualisation Benefits of virtualisation: Costs are cheaper in the long-term because money is saved by not purchasing multiple physical devices . Money is also saved due to less cabling and lower power consumption . If set up efficiently, it can be used for higher performance at a lower cost - "Do more with less" . Programs can be tested in a secure environment before main-system deployment. Simplified response to recover after a disaster because only the server needs to be fixed. Drawbacks of virtualisation: If not set up efficiently, users could face serious performance issues , as fewer servers do more work. If a single physical system fails , the impact will be greater . Initial set up is complex , requires technical knowledge and can cost a lot. Easier for hackers to take more information at once as the data is stored in the same place. Benefits of client virtualisation: All data is stored in one central location , making backup and disaster planning easier to manage . The whole system can be managed , secured and updated from the server , rather than from each individual system. Hardware costs will be reduced because the virtual clients do not store or process their own data , meaning they can be of a low spec . Users can have multiple virtual machines and log in remotely (from anywhere with internet access ). Drawbacks of client virtualisation: Users will be unable to work if network connectivity is lost . There is a high strain on the server as the virtual clients do not store or process data themselves . An increased load on the server might result in poor performance for each client, especially with multiple connections . As the data is stored in one location , there are security risks of unauthorised access if the server is not adequately protected . Server Virtual Clients Cloud Technology 'The cloud ' is storage that is accessed through a network , primarily the internet. A cloud server is an example of storage virtualisation as data may be stored across multiple physical devices . There are three different types of cloud storage: Private cloud is where a business will have its own data centre that employees can access. This allows for flexible and convenient data storage and gives the business control over data management and security . Users of the private cloud will not usually have to pay individually for access - but the company will need to spend a lot of money on set up and maintenance . Public cloud uses third-party service providers such as Google Drive or DropBox to provide storage over the internet . Public cloud is usually a pay-for-use service , where businesses will pay for specific amounts that they need. Data management and data security is maintained by the cloud provider and the business is dependent on them providing constant access and deploying effective security measures. Hybrid cloud uses a mix of on-site storage (private cloud) and third-party (public cloud) services . Organisations can move workloads between private and public clouds as their specific needs and costs change . A benefit of hybrid cloud is that it gives an organisation greater flexibility and data storage options. As an example, a company could use on-site or private cloud storage to hold sensitive information and third-party, public cloud services to hold less important data .

Learn about the moral and ethical issues of computing such as computers in the workforce, automated decision making, artificial intelligence, environmental effects, censorship and the internet, monitor behaviour, analysing personal information, piracy and offensive communications, layout, colour paradigms and character sets. Based on the OCR H446 Computer Science A-Level specification. Exam Board: OCR A-Level Specification: Computer Science H446 5.2 - Moral & Ethical Issues Watch on YouTube : Moral & Ethical Issues #1 Moral & Ethical Issues #2 Artifical Intelligence Technology and the internet have transformed society , bringing huge benefits but also raising new ethical , social and environmental challenges . Below are some key modern issues linked to computing and digital systems . Moral & Ethical Issues Computers in the Workforce: Computers and automation have increased productivity and created new tech-based jobs , but they have also led to job losses in areas where machines can replace human labour . This raises concerns about unemployment and retraining in many industries . Automated Decision Making: Systems such as credit checks and recruitment tools now make decisions automatically using algorithms . While this can save time and reduce human bias , it can also lead to unfair or inaccurate outcomes if the data or programming is flawed . Artificial Intelligence (AI): AI allows machines to learn and make decisions without explicit human control , improving fields like healthcare and transport . However, it also raises ethical questions about accountability , job loss and the potential misuse of intelligent systems . Environmental Effects: Computers require energy to manufacture , use and dispose of , contributing to electronic waste and carbon emissions . Recycling and energy-efficient design can help reduce the environmental impact of modern technology . Censorship and the Internet: Some governments and organisations restrict access to information online to control what people can see or share . While this can protect users from harmful content , it can also limit freedom of expression and access to knowledge . Monitoring Behaviour: Digital systems and surveillance tools can track users’ actions , such as browsing history or location . This can improve safety and security but also raises privacy concerns about who collects this data and how it’s used . Analysing Personal Information: Companies and governments can collect and analyse large amounts of personal data to improve services or target advertising . However, this creates risks of data misuse , discrimination or identity theft if information isn’t protected properly. Piracy and Offensive Communications: The internet makes it easy to copy and share content illegally , such as music , films or software , leading to lost income for creators . It can also be a platform for offensive or harmful communication , such as trolling or cyberbullying , which can have serious social effects . Layout, Colour Paradigms, and Character Sets: Design choices like layout , colour schemes and character sets affect how accessible and inclusive digital content is. Using clear design , appropriate colours and Unicode character sets helps ensure that websites and software can be used by people of all languages and abilities .

Part 2 of the Greenfoot Tutorial for the Eduqas / WJEC GCSE 2016 specification. Right-click on your main character class and select ' Open editor '. The editor allows you to write different methods - actions that the class can perform. The act() method will repeat whenever the Run button is pressed. 1. Open the Code Editor 2. Movement with the Arrow Keys Greenfoot Tutorial Watch on YouTube: 2. Copy the Code CAREFULLY You need to use an if statement to check if a certain key (like the right arrow key) is being pressed down . An if statement must be contained in standard brackets . After each if statement, the proceeding code must be typed within curly brackets - see the image on the left . Tip - If the brackets are on the same line then use the standard brackets ( and ) If the brackets are on different lines then use curly brackets { and } Your code must be perfect or it won't work. 'Greenfoot ' requires a capital G and the isKeyDown method most be written with a lowercase i but uppercase K and D . When the right arrow key is pressed the object will change its rotation to 0° which is right . It will also move 1 place in this direction. Rotations in Greenfoot: 3. Code the Other Arrow Keys Directly underneath the if statement for turning and moving right, add the code for turning and moving down . You can see in the diagram above the degrees to rotate in each of the four directions . Write the code to move in all four directions. Ensure you have the correct number of brackets or the program won't start. Remember brackets that start and end on the same line are ( ) and brackets over multiple lines are { } . 4. Compile and Run Click the Compile button at the top of the code editor . Then you can go back to the main Greenfoot window and click Run . Press the arrow keys to test your main character moves .

Learn about methods of physically protecting data such as biometric devices, RFID and tokens, privacy screens and shredding. Based on the 2016 OCR Cambridge Technicals Level 3 IT specification. 5.4 - Physical Security Exam Board: OCR Specification: 2016 - Unit 1 RFID & Tokens Radio-frequency identification (RFID) uses electromagnetic fields to attach tags to physical objects . RFID tags can be embedded within 'dumb' objects such as clothing, packages and even animals. RFID is used with security tokens (such as an ID keycard ) to permit the access of authorised people to certain areas. RFID can be used by IT companies to track equipment and manage access . Shredding This is the cutting up of documents (paper or CDs ) into small pieces so that they cannot be reassembled and read. Sensitive data on paper or optical disc should be shredded when no longer required. Locks A lock can be used to prevent access to server rooms or sensitive data stores . Only authorised personnel with the right key will have access. Physical Security Measures Biometrics Biometric devices require the input of a human characteristic (such a fingerprint , iris or voice scan ). The biometric data is checked against previously inputted data in a database . A match will allow access to the user. See more in section 1.1 . Privacy Screens These plastic screens are placed over a monitor to obscure the screen to anyone except the person sitting directly in front of them. This prevents shoulder surfing and prevents data from being read by unauthorised people nearby. Q uesto's Q uestions 5.4 - Physical Security: 1.

Learn about ethical issues of IT including whistleblowing, discrimination, online safety and bias. Based on the 2016 OCR Cambridge Technicals Level 3 IT specification. 5.1 - Ethical Issues Exam Board: OCR Specification: 2016 - Unit 1 What are ethics? Ethics refers to what is right and wrong . The following issues are often linked to or backed up by legislation. Whistle Blowing Definition: When a member of staff reveals that the organisation they work for are engaging in unlawful practices . This could include breaking privacy laws , threatening staff or environmental damage . In the UK , whistleblowers are protected by the Public Interest Disclosures Act (1988) . Under this law, whistleblowers are protected from being fired or being victimised (e.g. ignored for promotion ) as a result of their whistleblowing. Large organisations should consider establishing a whistleblowing policy that would outline how employees can raise concerns , who they should speak to and the support available to concerned staff. A famous whistleblower is Edward Snowden , who revealed in 2013 that many governments, including the USA and the UK, were spying on their civilians with widespread undocumented surveillance. Should Martin reveal that his company is dumping old computers into a lake or just stay quiet? Graham feels that, because of his disability, he is being ignored for a promotion that he deserves. Discrimination Definition: When an employee is treated unfairly because of a personal or physical characteristic over which they have no control . The Equality Act (2010) ensures equal treatment for all people irrespective of: race sexuality gender disability marital status (and many more) Examples of discrimination include offensive talk, harassment, unequal pay and being ignored for promotion. Use of Information Definition: Laws such as GDPR (General Data Protection Regulation ) and specifically the Data Protection Act (2018) ensure that organisations must responsibly process personal data. Organisations have a legal obligation to keep their employee and customer personal data secure and out of reach from unauthorised viewers. Considerations should be made about how the information is ethically collected , stored and processed . DataDyne backs up customer information on cloud storage - what if this data is compromised ? As part of quality assurance, Selside Bank double check performance reviews before submission. Codes of Practice Definition: A set of rules which explains how people working in certain professions are required to behave . Organisations may have a code of practice for: Confidentiality (rules on what data can and cannot be shared with others), Quality assurance (ensuring high quality is maintained for all products/services), Behaviour (setting out how employees are expected to behave at work and in communication with each other and customers), Equality and discrimination (being understanding and providing fair access to all employees). Employees must agree to the codes of practice so they are clear on their expectations of what is and isn't acceptable at work. The organisation can then discipline employees that broke the codes of practice they formerly agreed to. Online Safety Definition: Often companies will provide an induction (training ) to new employees about the organisation’s code of practice for using the internet whilst at work . If an individual does not behave safely online or breaks the organisation's codes of practice (by gambling at work for example) then they may be punished (e.g. fined or fired). Employees can ensure that they are safe online by using secure passwords that are regularly updated and preventing web browsers from remembering login details . Miriam changes her password each month to minimise the chance of hackers accessing her account. The CEO of Honey Media apologies in public after biased information led to a lawsuit and loss of reputation. Bias Definition: This is technically correct, but slanted , information that presents a one-sided view . For example, end-of year financial data that focuses on profits and ignores significant losses. Poor quality information may lead to an organisation being misinformed and not sufficiently responding to their customers' needs - for example if a survey was only completed by a small number of people it could generate biased results. As a result of poor quality information, organisations may suffer from damage to their reputation due to negative feedback and reviews from customers, possibly posted online. A lack of trust can occur if customers feel neglected because of decisions made using biased information of a poor quality, therefore reputational damage may lead to loss of customers .
