I'm employed on a full time basis my employer wants to put me on a salary with no changes. What is the difference between full time employee and salary?

As for pay, my understand is that full time allows the employee to be paid for overtime. A salaried person is not paid for overtime.

To add to Wondergirl's response a full time worker will get paid on an hourly rate, while a salaried employee will get paid the same amount per pay period whether he or she works the same amount.

For an example a full time employee works 35 hours one week will receive an hourly rate times 35 hours, and if the employee works 50 hours the employee will be paid for 40 hours at the hourly rate and 10 hours at 1.5 times the hourly rate. So by this example the full time emplyee will receive a different amount of pay based on the number of hours worked.

A salaried employee will receive the same amount of pay whether the employee worked 30 or 50 hours.

So to answer your question it will come down to the average amount of hours you work per week at your hourly rate and the amount of the salary per week with the number of hours you will be expected to work per week. It could also come down to other advantages or disadvantages of being a salaried employee over a full time employee.

A full time employee will be scheduled to work a normal work week each week. What is normal will vary by company but is generally between 35 and 40 hours a week.

Full timers can be either hourly or salaried.

A full time employee costs more than stated annual pay and it also include hard costs as Social Security, medicare contributions, employee benefits such as health care or 401K plans, training costs and time, vacation time, paid holidays and sick time holidays.

I'm sorry, but you are wrong on both counts.
There is no relationship between costs and type.
Both types include the usual payroll deductions of any wage earner.
Perhaps you are confusing salaried wage earner with contract work.

Thank you for trying to help our members. However, we try to maintain a high standard of accuracy in the answers posted here. While it is true that many part time workers do not get benefits, F/T vs P/T has no bearing on SS or Medicare taxation.

Also that wasn't the question. The OP is a F/T employee, but apparently paid hourly and the employer wants to switch to salaried. The only cost saved by the employer there is O/T.
