This is another basic technique used to crypt data. It involves replacing a alphabet by another alphabet like replacing a with d , s with u, etc.
For a novice it is difficult to decrypt/decode the data on first go but there are techniques with which it can become easy.
The first step involves locating the high frequency letter in a given language. for example e,t and a are most used letters in English. So try replacing the letter with highest frequency in the given code with either of these characters.

Second step would be word recognition, if the words are spaced correctly the task becomes really easy like if a word contains a single letter , it could either be a or i. For a two letter word the options are or, at, an, etc. It requires some trial and error.
