Fallacies of distributed computing are mistakes that people often make when they try to work with computers on a network. It can happen if someone makes assumptions without understanding how computers actually work. For example, they might assume that something will always happen quickly when working with computers on a network, but it can actually take a long time. Another example is assuming that the network will always be reliable and never go down, but this could also be false. It's important to remember these fallacies and not assume anything when working with computers on a network.
