When documenting your network infrastructure, you are obtaining both hardware data to document your infrastructure's physical structure and software data to document the existence and configuration of the protocols in use on your network.
1. perpendicular-a straight line at right angles to another line. straight line-a line traced by a point traveling in a constant direction; a line of zero curvature; the shortest distance between two points is a straight line.
1 When asked to find an equation that is perpendicular to a given equation, sometimes students believe that the perpendicular line MUST have the same y-intercept. 2  This is not necessary in order for two lines to be perpendicular. 3  Students think a slope of 0/2 and slope of 0/-4 are neither parallel nor perpendicular.
