Roth is post-tax. You are taxed on the income, and you put the income into an IRA. Retirement withdraws are tax free.
Tax man gets his money either way.
401(k)s are typically Traditional, but Roth 401(k)s are starting to become a thing.
401(k)s have a 17k/yr contribution limit. Roth has a 5k/yr contribution limit.
Common with a 401(k) is an employer match. If you put in 5% of your earnings, the employer will match that earnings (giving you 5 + 5 = net effective 10%).
