Recursive functions solve problems by breaking them down into smaller subproblems, often leading to elegant solutions.

• A recursive function calls itself with modified parameters.

• Base case is crucial to prevent infinite recursion.

• Example: Factorial function - factorial(n) = n * factorial(n-1) with base case factorial(0) = 1.

• Example: Fibonacci sequence - fib(n) = fib(n-1) + fib(n-2) with base cases fib(0) = 0, fib(1) = 1.

Single mode and multiple mode are different types of fiber optic cables used for transmitting data.

• Single mode fiber optic cables have a smaller core diameter and allow for the transmission of a single mode of light, resulting in higher bandwidth and longer transmission distances.

• Multiple mode fiber optic cables have a larger core diameter and allow for the transmission of multiple modes of light, resulting in lower ba...read more
