Sway bar = Anti-roll bar = Stabilizer bar. The device that limits body roll around the cars longitudinal axis (axis that runs front to back).

Track bar = Panhard bar. Controls side-side movement of the axle in relation to the frame. A Watts link is a more advanced design for the same purpose.

A track bar is NOT a sway-bar.

The adjustable vs. non-adjustable has no bearing on the terminology. Both track bars and sway bars can be adjustable or non-adjustable. Those used on street cars are typically non-adjustable, while those on race cars will be due to the need to be able to tweak settings for each track condition.
