What is the primary function of an algorithm in computer science?
✔✔The primary function of an algorithm is to provide a step-by-step procedure or set of
instructions to solve a specific problem or perform a task.
How does abstraction help in managing the complexity of a computer program?
✔✔Abstraction simplifies a computer program by hiding complex details and allowing
programmers to focus on higher-level concepts.
What is the difference between a variable and a constant in programming?
✔✔A variable can change its value during program execution, while a constant remains the same
throughout the program.
What is the purpose of a function in programming?
✔✔The purpose of a function is to encapsulate a block of code that performs a specific task,
which can be reused throughout a program.

,How do you define a list in programming, and what is its primary use?
✔✔A list is a collection of ordered elements that can be accessed by their index, and it is
primarily used to store multiple values in a single variable.
What is a Boolean expression, and how is it used in decision-making in programs?
✔✔A Boolean expression is a statement that evaluates to either true or false, and it is used in
decision-making to control the flow of a program.
How does the concept of iteration improve efficiency in a program?
✔✔Iteration allows a program to repeat a set of instructions multiple times, reducing the need for
redundant code and improving efficiency.
What is the role of an API in software development?
✔✔An API (Application Programming Interface) provides a set of tools and protocols that allow
different software applications to communicate and interact with each other.
How does a binary search algorithm differ from a linear search?
✔✔A binary search algorithm divides the search interval in half repeatedly, while a linear search
checks each element in sequence until the target is found.

, What is the significance of data encryption in computer security?
✔✔Data encryption is significant because it protects sensitive information by converting it into a
secure format that can only be read by authorized parties.
What is the purpose of a loop in programming, and what types of loops are commonly used?
✔✔The purpose of a loop is to repeat a block of code multiple times until a condition is met.
Common types of loops include `for` loops, `while` loops, and `do-while` loops.
How does a conditional statement function in a program?
✔✔A conditional statement executes a block of code based on whether a specified condition is
true or false.
What is the difference between a `for` loop and a `while` loop?
✔✔A `for` loop runs for a predetermined number of iterations, while a `while` loop continues
until a specified condition is no longer true.
