What is the diferences between salary plus commision and straight commission?

Salary plus commission is one of the more common compensation structures used by employers to pay salesmen, although other job titles might also be rewarded this way. Employees receive a guaranteed base salary amount but also earn an undefined amount of commission based on the amount of sales they make.
