Computer software can be defined as a set of instructions that solve or perform a particular function in the computer. Other terms may refer to these instructions as algorithms. These algorithms or instructions can be grouped together to perform a specific task when this happens they are called applications.
In the simplest set of terms Computer software can be classified into two different types. These are System Applications and Computer Applications.
System software are basically software that are elated to the functioning of the computer. In cases of gadgets like smartphones and tablets, system applications are software that ensure they are functioning to the standard of the user. System software are normally written in a language that the machine can understand and are normally low level languages. They serve as an interface between the machines and the user.

System Software generally come already installed in the machine in question and are normally supplied by the manufacturers
Application software are a set of computer software that are developed to provide a solution to a particular problem. They normally run dependent of the System Software. Examples of Application software include Microsoft Office. In this case the application software can work together to accomplish certain needs like the spreadsheet.
