It means it forms a "straight line graph." That 'linear' has no relation to the data type used to represent the colour value -- whether it's represented by a normalised floating point value (0.0 ~ 1.0) or by an unsigned byte value (0 ~ 255).

WebIt’s apparent that the sRGB inventors selected the second of these points, and rounded its value to 4 significant digits to get 0.04045. They then used that rounded sRGB value to recalculate the Linear value, and got 0.00313080. I don’t know why their Linear value has more significant digits (5 or 6) than their sRGB value (4).
