Assemblers involve a set of concepts that enable code to be written in a language and then used to control the computer's operations. These concepts include the assignment of labels to represent locations in memory (e.g. letters such as X, Y, Z). Fixed names are given to operations such as STORE, LOAD and ADD as well as registers (e.g. R1, R2). Numbers written in decimal are also converted to binary.
Each line in assembly language translates to a single machine code instruction. Assembly languages are machine specific and require an understanding of the structure of the machine in order for that machine to be used to its potential. Assembly language is also very hard to learn.
