What is Overhead in Development?

Overhead: computation time, memory, bandwidth, or other resources spent on extra work, which is required to perform a specific task.

Software developers introduced some helpful techniques, like adding abstraction. These made the process faster, but it's not without some cost: it usually makes the end product slower. Sometimes just a bit, sometimes much more! Let's learn about overhead with some practical examples.
