Answer:
Both are a type of affix.
Both can change a word's meaning.
Explanation:
Prefixes and suffixes are both types of affixes. An affix is something that is placed at the beginning or end of a word to modify its meaning. The suffix /-ology/ can be added to a root word to change the meaning to /the study of/ whatever the word is. The prefix /de/ can be added to a root to indicate that something is going down; /a/ can be added to show it is going up. For example, the words ascend and descend use these prefixes to show where something is going.
There are many ways to convey suspense. In movies, you can do it with choosing specific tunes in the background and making sets that look eerie or by zooming in on people's faces (which was an old method). In music you can slow the tempo down and add some random high pitched notes from time to time such as those found in old horror films or classical tunes. In books, it is usually done through descriptions of the unknown or mysterious.
