Generally, if the name of compound ends in -ide it is made of only two elements (there are some common exceptions so you have to know them - like hydroxide and cyanide). So a "sulfide" is a compound containing sulfur bonded to an atom with a + charge (like silver sulfide, Ag2S)
If a compound name ends in -ate it is known as a radical or polyatomic ion. These are combinations of atoms that tend to stay together in a reaction. Most of these contain oxygen bonded to a nonmetal. So, a sulfate (or sulphate) contains SO4 and silver sulfate would be Ag2SO4.
Just be sure you know the formula for each sulfate because the number of oxygen atoms varies - phosphate is PO4 but carbonate is CO3 for example.

What Is Sulphate

Basically both are anions (negative ions).
Sulphate is actually the complex ion SO4, with a total charge of -2.
Sulfide is just the ion of sulphur, which can vary according to its oxidation state. For example, H2S is hydrogen sulfide where S has a charge of -2.

Chemicals that end in -ate and -ide indicate that they are combining with oxygen. The -ate has more oxygen than the -ide. In your question, sulphate/sulfate has one sulfur and 4 oxygen, while sulphide/sulfide has 3 oxygen. They are both dianions (negative ions of charge -2).

sulphate = SO4 2- sulphide = the second element in a compound for example Magnesium Sulphide (MgS)

Ions that end in "ate" and "ite" imply they are polyatomic ions that combine with oxygen. Those with "ate" have one more oxygen that the corresponding "ite" ion.
The overall charge on the polyatomic ions ending in "ate" and "ite" are the same. Also, if the prefix "per" isadded to the name, there is one more oxygen that the "ate", and if there is a "hypo" prefix, there is one less oxygen than the "ite" ion.
"per"sulf"ate" & "hypo"sul"ite"
In all cases, the charge on the overall ion is (-2). Only the oxidation state of sulfur changes within the ion.
Ions ending with "ide" imply monoatomic ions that have only a single element in the ion. The "ide" ending also tells you you are dealing with a binary compound(two elements) when the compound name ends in ide. The sulfure in the sulfide ion has a fixed oxidations state (-2)
