In general, 'salary' and 'wage' mean the same — a certain amount of money paid to a person for the work. But in fact, these words mean a different way of payment.
If someone gets a salary, that means that they get it once a week, month or another period of time that was agreed between the person and the company. In this case the amount of money that a person gets is fixed.
If you get a wage, that means that you are paid by the hour. In this case the cost of your hour is agreed with the company and the company pays for each hour that you spent for the work. For example, you completed the task in 6 hours. And, for example, your hour costs 20$. So, the company should pay you $180.
