Broad categories of Engineering

There are more than 25 major specialties in Engineering which are recognized and the major branches have numerous subdivisions. Engineers in each branch have a base of knowledge and training that can be applied in many fields. Electronics engineers, for example, work in the medical, computer, communications, and missile guidance fields. Because there are many separate problems to solve in a large engineering project, engineers in one field often work closely with specialists in other scientific, engineering, and business occupations.

On the broad the Engineering can be categorized as follows:

Mechanical Engineering : Mechanical Engineering major deals with the design, manufacturing and maintenance of mechanical systems. Few examples of mechanical systems are machines, automobile, aeroplane, elevators, earth movers and combustion engines.

Electrical & Electronics Engineering : Electrical and Electronics major deals with electronics and electrical equipments, such as GPS systems, robotic instruments and power generators.

Computers & Communications Engineering : Computers & Communications Engineering major deals with the computers & information systems. Hardware, Software and Communications are the major areas of study under this major. Example for the application of computer, is the use of computers in Banking system, use of websites to broadcast the information.

Civil Engineering : Civil Engineering Major focus on the construction and operation of building structures, roads, bridges, dams,etc. Study of Environment, behavior of earth materials, analysis and design of load bearing structures, use of satellites to gather information about the earth comes under this major.

Chemical Engineering : Chemical Engineering majors deals with the study of chemical process, and machineries that enable chemical reactions needed to make products or test theories. This major also involves the combined study of physics, chemistry, bio-chemistry and mathematics.

Bio-Technology : Bio-Technology major deals with the study of genetic systems,food processing, equipments used in the medicine field & manufacturing of the drugs as well. This majors deals with the study of any technological application that uses biological systems or living organisms to make or modify products or processes for specific use. The major application of biotechnology is in the field of agriculture, genetics, food production and medicine.
