Examples
parall
It need not have any.
Parallel lines.
None as in the form of a regular 5 sided pentagon.
Parallel is lines that never touch so if the lines never touch it is parallel but if so then it is perpendicular.
9, 8 to shift the bits in & 1 to move the byte into another register.
Oh, dude, a rhombus actually has 4 sides with all sides being equal in length. It does have 2 pairs of parallel sides, but it also has opposite angles that are equal, not to mention it's like a tilted square. So, yeah, it's definitely not a shape that's all about parallel sides and no perpendicular ones.
Try one of these: rhombus, parallelogram, square, rectangle
Why should an amplifier think it is better to have a heavier load? Use the 8 ohm speaker. If your amp has a 4-ohm output you can strap a pair of 8-ohm speakers in parallel across it to match impedances. When impedance is matched to the amp, maximum power transfer happens. A mismatch doesn't let maximum power get transferred. The sound of speakers that are matched in impedance with the amp will be the same as the sound of mismatched speakers at low power. At high power (high volume), you can end up with some problems. Talk to your local audio guy and get up to speed. Take a couple of cold drinks into the store when things are not busy, hook up the audio person with a beverage, and then open your ears and pay attention. You'll learn a lot.
