No they are not same , Socialism can be of multiple kinds Most of the continental European countries which have good developmental Index are Socialist democracies , Example Sweden , Denmark , Norway , Germany . The basic principle is that state is welfare state which look after needs of citizen such as education and health. The personal income tax is very high in these countries , In Sweden Tax is around 40-45% and on overtime income it goes up to 55% but university education for citizen is very cheap. In Socialism there is no compulsion for collectivism so individula excellence is cherished.

Communism on other hand is an ideology which depends on collectivism , Communism necessarily see the socity in terms of classes and foster an ideology of collectivism. Failure of communism lies in the fact that thrust on collectivism and punishing individual excellence pushes society to lowest common denominator rather then pulling up to the level of individualistic excellence.

No. Communism cannot be implemented unless there is an autocratic government. If anyone opposes the the pattern, he is severely punished or killed. There is no room for private trade or private possessions in communism, and it is against the natural tendencies of human beings. However,the socialism can allow democratic approach.. It allows you to vote, raise your voice, and even elect your government. The policy is to have every enterprise with social welfare in mind. Therefore private ownerships are not denied. That helps..
