Covalent compounds are made of 2 non-metal elements.
e.g.: CH4, C6H12O6
Ionic compounds are made of 1 metal and 1 non-metal element
e.g.: NaCl, CaS

a covalent compound is as a result of 2 non-metals bonding covalently by sharing electrons. an ionic compound is as result of a non-metal bonding to a metal by transferring electrons...

Easy. Look at the periodic table. On the left side of the STAIR division line are METALS. They have a tendency to lose electrons, and thus form positive ions or cations. On the other hand, elements above and to the right of the division line are non-metal elements and for the most part will rather have negative charges and form anions.
Ionic compounds are formed from metallic cations combining with non-metallic anions.
Covalents are formed for the most part from two or more non-metallic elements.
There you go, the basics! See how important the periodic table is? lots of info in shorthand.
Happy New Year!
