The main feature of modern computers which distinguishes them from other teams is that they can be programmed. This means that certain types of instructions (the program) can give the team and its treatment. While some teams may have strange ideas of "instructions" and "exit" (see quantum computing), the modern computer architecture based on the von Neumann machine code is often in the form of an imperative programming language.
In practice, the computer program could be a few steps, or to expand into many millions of instructions, as well as word processors and web browsers, for example. A typical modern computer can execute billions of instructions per second (Gigaflops), and rarely makes a mistake of several years of use. Large computer programs are made up of several million instructions to take teams of programmers years to write, and because the complexity of the task almost certainly errors.
