Civil Engineering (CE)
Civil engineering is an engineering field that emphasizes on dealing with the constructions and maintenance of structures, such as roads, bridges, canals, dams, and buildings. Even though this is the main focus of civil engineers, they are also capable of doing much more outside their field. Civil engineers are also found in the aerospace industry, where they design planes and in the automotive industry, where they improve the quality of vehicles.
Mechanical Engineering (ME)
Mechanical engineering is a field that incorporates engineering ideas to design and manufacture devices that are as small as inkjet printer nozzles to spacecrafts. A mechanical engineering must have a deep understanding of forces and the environment that the product will encounter. Mechanical engineering is the most diverse fields of engineering because they are involved in anything from the aerospace industry to the automation industry.
Industrial Engineering (IE)
Industrial engineering integrates concepts from science, math, and engineering to make operations more simple. Industrial engineers must have experience in many fields because their work requires them to work well with people and have a thorough understanding of computer simulation and problem solving. Industrial engineers are often involved in resource allocation and scheduling and quality assurance.
