Covariant and contravariant components refer to how vector and tensor components transform under a change of basis. Covariant components (lower indices) transform with the basis, while contravariant components (upper indices) transform inversely to the basis changes.

Vector components are the projections of a vector along the axes of a coordinate system, allowing for the analysis and manipulation of vectors in terms of their individual contributions along each axis. These components are crucial for simplifying complex vector calculations in physics and engineering, enabling the resolution of vectors into perpendicular directions for easier computation and understanding.

Change of basis in linear algebra refers to the transformation of a vector representation from one basis to another, allowing for different perspectives or simplifications of a problem. This process involves a transition matrix that converts coordinates of vectors with respect to one basis into coordinates with respect to another basis, preserving the vector's intrinsic properties.
