Without getting too technical, the basic difference is that the Air Force Reserve is the reserve forces for the active Air Force, and the Air National Guard is specifically attached to one state. The governor of the respective state is the commander in chief for their guard. The same goes for the Army.
Both the Air Force Reserve and the Air National Guard ARE part of the Air Force. The reserve is federal while the guard is state. Both wear name tapes that state U.S. Air Force on their uniforms.
It's a reserve force of the military.
If you are referring to the U.S. Army and Air Force reserves, yes, they are known as the "National Guard." Actually U.S. Army Reserve and Air Force Reserve are federal reserve forces. Air and Army National Guard are state forces that can be federalized by the President.

In the United States, there are seven Armed Forces Reserve Components. These include the Army Reserve, Navy Reserve, Marine Corps Reserve, Air Force Reserve, Coast Guard Reserve, the Army National Guard, and the Air National Guard. Each component serves to provide additional support and personnel to active-duty forces as needed.
A reserve force of the Air Force but under state authority unless called into federal service.
The National Guard serves as a reserve component of two federal forces - the Army (Army National Guard), and Air Force (Air National Guard). Policies, procedures, etc. adopted by these branches are subsequently adopted by their National Guard components.
All branches have a reserve component. The Army and Air Force also have a National Guard.
Total force Concept
According to 10 USC Chapter 13 § 311 - the National Guard is an organized militia of the US. While individual National Guard units may be federalized and activated subordinate to Army (or Air Force as with Air National Guard) authority, they are a reserve component, and are part of the US Army or Air Force.
Technically, one could say that all the National Guard are militia, in accordance with the Militia Act of 1903, which classes the National Guard as the Organized Militia, or one could argue that none of the National Guard fit the Constitutional definition of a militia, as they wear the uniform of the Army, and on the basis that the Total Force Policy ultimately maintains that the Regular Army, Army Reserve, and Army National Guard are one force.Whatever your stance on this matter is, all National Guard personnel are required to attend the same Basic Training and Advanced Individual Training which their counterparts in the Regular Army, Army Reserve, Air Force, and Air Force Reserve are required to attend.Some states have an auxiliary branch, known as State Guard Forces, State Defence Forces, etc. While administered under the National Guard bureau of each state, these outfits are not actually members of the National Guard.
