What adapter do I need? Will my computer plug work? What's the electrical current? What do the wall sockets look like? Why oh why have we not all come together to decide a common electrical current and wall socket for the world? It makes travel difficult, especially if you're coming from the North America, a few countries in South America or Japan - the only places that use 110V instead of 220V. But anyway, armed with a bit of knowledge and some adapters, you'll be able to use your electronic devices.
