What is frame of reference?

In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements.
In n dimensions, n+1 reference points are sufficient to fully define a reference frame. Using rectangular (Cartesian) coordinates, a reference frame may be defined with a reference point at the origin and a reference point at one unit distance along each of the n coordinate axes.
In Einsteinian relativity, reference frames are used to specify the relationship between a moving observer and the phenomenon or phenomena under observation. In this context, the phrase often becomes "observational frame of reference" (or "observational reference frame"), which implies that the observer is at rest in the frame, although not necessarily located at its origin. A relativistic reference frame includes (or implies) the coordinate time, which does not correspond across different frames moving relatively to each other. The situation thus differs from Galilean relativity, where all possible coordinate times are essentially equivalent.

Answer:
Reference Frame is an axis system from which motion is observed. A Clock is attached to measure time.
Reference Frame can be stationary or moving.
Explanation:
There are two types of Reference Frame :--
•Inertial Reference Frame :- A frame of reference in which Newton's first law is not valid is called as Inertial Reference Frame.
•Non-Inertial Reference Frame :- A frame of reference in which Newton's first law is not valid is called as Non Inertial Reference Frame.
