The Input-Process-Output (IPO) model is a framework for understanding how systems work by breaking them down into three main components. Inputs are the resources, data, or information that enter a system, necessary for the process to begin. The process is a series of actions or steps 'copied from e x a m p l a z a . c o m free' that transform inputs into outputs, involving the manipulation, calculation, or transformation of input data.

While a byte is made up of 8 bits, it serves as a more practical unit for measuring data storage and memory capacity. A byte can represent 256 different values (2^8) and is commonly used to quantify data sizes and system capabilities.
