This is a short article about the different byte sequences. For simplicity, I show the sequences up to 32 bit. For the example, I use a 32 bit register and name the bytes A, B, C and D where our data is stored. Typically, you have either big endian or little endian,...

Strategy Design Pattern

The definition of strategy patterns is as follows: „Strategy patterns define a family of algorithms, encapsulate each one, and make them interchangeable.“ The strategy allows the algorithm to vary independently of the clients who use it. Okay, now we...
