Difference Between Software Engineering and Computer Science
Many people confuse software engineering with computer science, but they have distinct differences:
| Software Engineering | Computer science |
| Focuses on Building, designing and maintaining software systems. | Computer science is the study of how computers perform theoretical and mathematical tasks. |
| It involves the study and application of software only. | It involves the study and application of software and hardware both. |
| It involves some areas of study which are software development, software testing and quality assurance. | It involves areas of study which are networking, artificial intelligence, database systems etc. |
| Software engineering majorly defines architectural and structural properties. | Computer science involves the study of both principals and the use of computer. |
