P.A.R. or PAR means Planed All Round when used in reference to timber. In other words, the timber has been prepared. The alternative is rough or sawn or unprepared timber. This has been cut to size but not finished in any way. Timber that is PAR is planed but there is no guarantee that the corners will be square!
Oh, dude, rough sawn timber is basically wood that's been cut straight from the log using a saw, but it's not been planed or smoothed out all nice and pretty like your grandma's dining table. It's like the lumberjack of the wood world - all rugged and raw, ready to be transformed into something cool... or just left looking like a rustic charm in your backyard.
Timber is just another name for wood, In practice wood in its rough form is usually refered to as timber, tree trunks unprocessed are probably timber in it's purest form. In a house unfinished wood ( generally found in the roof and beneath the floor) is referred to as timber e.g. roof timbers or floor timbers/joists. Timber which has been planed (smoothed) and finished off e.g. skirting boards and window sills are referred to as 'joinery' grade or finished, they are still however timber and the difference is a discriptive reference rather than a physical difference.

The timber conversion process is the process of changing rough timber into usable wood like boards, plywood, etc.

Re sawn lumber is achieved by re-processing smooth standard milled lumber to achieve a roughened surface, normally for aesthetics. The lumber is passed along a saw blade to achieve the desired effect. The finished size is smaller than nominal call-out dimension. Rough sawn lumber is the board, plank or timber prior to milling for final sizing. Rough sawn lumber is larger in dimensions to the nominal call out. Rough sawn lumber is sometimes referred as rough milled lumber when certain exact sizes are desired.
A joist, either floor or ceiling are the boards that go across the building and tie the walls together. A timber joist would be a rough sawn beam. Basically a tree that has been squared up.
