The talk will present concepts and basics of distributed computing which are important (at least from the presenter's point of view!), and should be known and mastered by researchers, and Master students. Those include: (a) a characterization of distributed computing (which is too much often confused with parallel computing); (b) the notion of a synchronous system and its associated notions of a local algorithm and message adversaries; (c) the notion of an asynchronous shared memory system and its associated notions of universality and progress conditions; and (d) the notion of an asynchronous message-passing system with its associated broadcast and agreement abstractions, its impossibility results, and approaches to circumvent them. Hence, the talk can be seen as a guided tour to key elements that constitute basics of distributed computing.
