Friction is a force that acts on all touching objects. Friction is caused by the roughness of on object. Even if an object feels smooth to the touch, it will never be perfectly smooth because there will always be microscopically small peaks and valleys at the atomic level. What friction does is essentially try to prevent an object from moving or continue moving. There are two types of friction, static and kinetic. Static friction must be overcome to get something moving, kinetic friction must be overcome to keep something moving. They both have values that depend on the two surfaces touching and are referred to as the coefficient of their respective term. Note: the coefficient of static friction is always higher than that of kinetic for the same two materials.
