Cortana is a personal digital assistant, a kind of silicon secretary who can help make your life easier. Instead of searching for things you ask Cortana - so if you want to know what the weather forecast is, how many pounds are in a kilo, who's winning the football or when Jim's birthday is, you'll ask and Cortana will give you the answer. As Texas sang, she has a Halo.
The First Amendment to the U.S. Constitution is what guarantees the freedom of the press in the United States.
The Constitution and the Bill of Rights only limit the actions of the government, not private parties. Therefore, freedom of speech does not apply to the private workplace, and the Second Amendment does not guarantee the right to carry a gun in the office.
