According to Islam, there are three general words used in Arabic to refer to non-believers in an Islamic context. There is Kaafer (often spelled Kafir) which means "denier" or "negator" since they are denying or negating the truth of God. A Kaafer is someone who rejects God in an Islamic context. There is also Mushrik which refers to a polytheist or pagan, i.e. someone who believes in more than one God. Finally, there is Ahl al-Kitaab or Ahl adh-Dhimma which refer to the "People of the Book" or "Protected Peoples", non-Muslim monotheists like Jews and Christians.
The term "infidel" in English is usually used as an analog for Kaafer, not for the other groups, so a person who is not a Muslim is not necessarily an infidel either, he could be a Mushrik or a member of Ahl al-Kitaab. However, the treatment of Mushriks is not terribly different than the treatment of Kaafers and the treatment of the members of Ahl al-Kitaab depends strongly on the particular ruler in place at a given time.
Quran 60:8
That verse explains it all.
An infidel is simply someone who believes in a religion (or nonreligion) different than you do. Muslims use the term infidel to refer to Non-Muslims. Christians use the term infidel to refer to Non-Christians.
Muslims consider anyone who does not believe in their way an "infidel". Infidel means unbeliever. The term was also used by Christians in the Crusades to refer to Muslims.
