The difference between landing visa and visa-free

I think the difference between landing visa and visa-free is as follows:

Landing visa needs to apply for a visa, which is applicable to the case that it needs to arrive at the designated port and enter the country directly by plane, and it needs to pay a visa fee; Visa-free does not require a visa, and it is applicable to the case that it is recognized by the immigration officer at the time of entry, and no fee is required.
