  - The above statement is an example of the concurrency feature which is a basic feature for designing a software.
  
  - All the software are meant to be executed sequentially.
  
  - By sequential execution it means that the coded instruction will be executed one after another implying only one portion of program being activated at any given time.
  
  - Say, a software has multiple modules, then only one of all the modules can be found active at any time of execution.
  
  - In software design, concurrency is implemented by splitting the software into multiple independent units of execution, like modules and executing them in parallel.
  
  - In other words, concurrency provides capability to the software to execute more than one part of code in parallel to each other.
  
  - It is necessary for the programmers and designers to recognize those modules, which can be made parallel execution.
  
  - The spell check feature in word processor is a module of software, which runs along side the word processor itself.
