4 Key Points To Be Mentioned: (Response time: 1.5-2 minutes) 

• Interest in Problem Solving [1]

• Passion for Technology and Innovation [2]

• Excitement about the Future of Computing [3]

• Desire to Build Useful Applications [4]

Sample Response:

I want to study computer science because I love solving problems and finding new ways to approach challenges. Computer science gives me the tools to tackle complex problems and build solutions that can make life easier or more efficient. It’s satisfying to take a problem apart, understand it, and then create a working solution using code. [1]

I'm also fascinated by technology and how it changes our world. Computers and software are everywhere, transforming industries like healthcare, education, and finance. I want to be part of this change, helping to create new technology that makes a real difference in people’s lives. [2]

The future of computing excites me, especially areas like artificial intelligence and data science. These fields have the potential to change the way we live and solve problems on a global scale. Learning computer science would let me explore these areas and be part of developing technology that impacts society. [3]

Finally, I want to learn how to build applications that people use every day. Whether it's a simple app to organise tasks or a complex program that analyses data, I want to create software that’s useful and impactful. Studying computer science will give me the skills I need to bring my ideas to life. [4]

• Definition of a Binary Search [1]

• How Binary Search Works [2]

• Efficiency and Time Complexity [3]

• When Binary Search is Useful [4]

Sample Response:

A binary search is a method used to find a specific item in a sorted list by repeatedly dividing the list in half. It compares the middle item of the list to the target item, and then decides to continue the search in either the upper or lower half of the list. This process keeps narrowing down the search range until the item is found or it’s clear it’s not in the list. [1]

Binary search works by checking the middle item first. If the target item is smaller than the middle item, the search moves to the lower half of the list; if it’s larger, it shifts to the upper half. This method quickly reduces the number of items to check, making it much faster than searching each item one by one.  [2]

The efficiency of binary search is due to its time complexity of O(log n), meaning it only takes a few steps even for large lists. For example, in a list of 1,000 items, binary search would only need about 10 comparisons, which is much faster than checking every item. This efficiency makes it suitable for situations where speed is important. [3]

Binary search is especially useful for large, sorted lists, like databases or dictionaries, where finding items quickly is essential. It’s a powerful tool when the list is already in order, saving time and making searches much faster compared to other methods. [4]

4 Key Points To Be Mentioned: (Response time: 1.5-2 minutes) 

• Definition of a Microprocessor [1]

• Function of a Microprocessor [2]

• Components of a Microprocessor [3]

• Importance of Microprocessors in Computers [4]

Sample Response:

A microprocessor is a small electronic chip that acts as the brain of a computer. It processes data and performs calculations to make the computer work. It is designed to execute instructions, perform tasks, and control other parts of the system.[1]

The microprocessor functions by receiving instructions from the computer’s memory, processing them, and sending out commands to other components. It manages tasks like calculations, logic operations, and decision-making. This makes it essential for running software and applications.  [2]

A microprocessor contains several key components, such as an arithmetic logic unit (ALU), control unit, and registers. The ALU performs calculations, while the control unit coordinates the actions of different components. Registers store temporary data for quick access.  [3]

Microprocessors are important because they control the performance of a computer. They determine how fast a computer runs programs, process data, and manage tasks. The better the microprocessor, the faster and more efficient the computer. [4]
