Main Difference
The main difference between Fence and Wall is that the Fence is a freestanding structure preventing movement across a boundary and Wall is a vertical structure, usually solid, that defines and sometimes protects an area
Fence
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).

Brick walls
Defensive walls in fortifications
Doors, mobile walls on hinges which open to form a gateway
Glass walls (only when most of the wall, in smaller amounts it is called a window)
