When we write software, it is typically used for the transformation and transmission of data so that it can become information. The device that runs our programs (the hardware upon which our systems run) isn’t aware of concepts such as human language or the protocols that drive the internet. Data is simply a sequence of bytes: a stream of ones and zeroes. Those byte values only become information when they are evaluated in their proper context. For example, consider the following sequence of bytes.
