"This definition has several important aspects. The first one is that a distributed system consists of components (i.e., computers) that are autonomous.

anonymousThis means that one way or the other the autonomous components need to collaborate.

~ This means that by some method or by another method (whatever method it may be) the independent parts need to work together.

In short, 'one way or the other' (usually 'one way or another') means 'somehow', that is, 'in some unspecified way'.
