What do you think of this paintball gun?
It's a decent beginner setup, but it's a crappy dealLook around for used gearIt's very easy to find a setup like that go for $50, or lessAssuming your budget is in the $100-150 range, you could get yourself a used, low-end electronic marker ($40), aluminum compressed air tank ($40), agitated hopper ($20), and a decent mask ($30) and pack ($20)It's $15 more than the package you found, but it'd be worth it.
A bit vague in the questions1) Bridges forward based on a routing tableThey know what addresses are on which side of the bridge, usually by the MAC addresses2) Norepeaters do not extent the range, they simply repeate in all directionsOnly switches can extend, as they store and forward packets, which allows re-timing and a new 100M segmentTo go 500M, you would need 4 switches, one every 100M if using CAT5 or CAT6 wiringThat is stretching it, better to go with a fiber optic cable, which can go at least 2000M per segment (some forms can go farther) 3) No idea what you are asking reallyMost computers can handle almost any network rate, but multiple Gigabit may pose some issues with some slower machines.
