Shader - SV_Target

Questions & Answers
1

I am trying to understand and learn how to create shaders and I can’t find any documentation about specific words.

		fixed4 frag (v2f IN) : SV_Target
		{
			fixed4 col = tex2D(_MainTex, IN.uv + float2(0, sin(IN.vertex.x/75 + _Time[1]) / 50 ) );
			// just invert the colors
			//col = 1 - col;

			col[2] = .4;
			//col[1] = .1;
			
			return col;
		}

What is that : SV_Target? How is it affecting the function?
