The term engineering is derived from the word engineer, which itself dates back to 1390 when an engineer referred to “a constructor of military engines.

Engineering is a major and wide work category. It is referring to many jobs that use science, maths to solve many problems. Engineering asks for disciplines that include all engineering field like mechanical, electrical, chemical, civil, it, and all among others.

The reason behind it is broad filed. There some engineering are main branches of this field which are as below:
• Chemical engineering
• Civil engineering
• Electrical engineering
• Computer engineering
• IT engineering
• Mechanical engineering
• Plastic engineering

New specialties sometimes combine with the traditional fields and form new branches – for example, Earth systems engineering and management involves a wide range of subject areas including engineering studies, environmental science, engineering ethics and philosophy of engineering.
