A user enters "http://example.com" in their browser's address bar. What protocol is the browser using to retrieve the webpage?

• File Transfer Protocol (FTP)
• HyperText Transfer Protocol (HTTP)
• Secure Socket Layer (SSL)
• Domain Name System (DNS)

On a webpage you need to preserve multiple consecutive spaces between words but browsers tend to collapse them into a single space. Which HTML entity would you use to ensure these spaces are rendered properly especially for maintaining alignment or specific formatting?

• Use regular space
• Use <br> tags
• Use &nbsp;
• Use CSS padding

You're managing a website and your users frequently receive emails that look like they're from your company but aren't. What security vulnerability should you be most concerned about?

• Phishing
• Cross-site scripting
• SQL injection
• Man-in-the-middle attack

You're developing a program that processes user input. Before sending data over a network you want to ensure it’s protected against third-party interception. What should you use to secure the data?

• Firewall
• Encryption
• DNS lookup
• Data redundancy

Your program continuously checks the temperature from a sensor and reacts only when the temperature falls below a certain threshold. What type of loop are you using to implement this behaviour?

• For loop
• Infinite loop
• Do-while loop
• While loop

Why is low power consumption a crucial feature for IoT devices particularly those deployed in remote areas?

• It enables faster data transmission
• It extends device operational lifespan without maintenance
• It improves processing speed
• It allows larger data storage on the device

You are writing a program that calculates payroll for a company. Before the program can be run on a computer you need to translate the code into something the computer can execute directly. What is this process called?

• Parsing

• Class and Object
• Function and Variable
• Method and Instance
• Array and List

In machine learning what is the primary distinction between supervised and unsupervised learning tasks?

• Supervised learning requires labelled data
• Supervised learning uses clustering unsupervised uses classification
• Supervised learning is faster than unsupervised learning
• Supervised learning does not use training data while unsupervised does

When training a machine learning model what is the role of a 'loss function'?

• It tracks the learning rate of the model
• It measures the difference between predicted and actual values
• It tunes the model's weights
• It determines the size of the dataset required for training
