Could you please help me ans correct my notes? Thanks in advance.


Firstly, there is (not a shadow of a) no doubt that after the post-industrial era, an ever-increasing number of people are involved in (working with) the computing field/the field of computing (computers). A study has shown that every student in various all university fields courses should pass at least one course regarding computer science, and thus so that universities not only raise students' awareness of computer use realms, but also broadens their horizons, and expands their knowledge about computers. 
 
Secondly, all of us are living in a modern society which requires us to have some  makes us have relevant computer knowledge. Furthermore, different many job opportunities in society require that we have having rudimentary skills about computers, so if we do not know how to work with computers, we cannot shall struggle to find any a jobs to and will be unable to make a living.
