Electrical engineering

Electrical engineering (sometimes referred to as electrical and electronics engineering) is a professional engineering discipline that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply. The field now covers a range of sub-disciplines including those that deal with power, control systems, electronics and telecommunications.
The term electrical engineering may or may not encompass electronics engineering. Where a distinction is made, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronics engineering deals with the study of small-scale electronic systems including computers and integrated circuits.[1] Another way of looking at the distinction is that electrical engineers are usually concerned with using electricity to transmit energy, while electronics engineers are concerned with using electricity to transmit information.

Deaf-mute:

Deaf-mute:
It is an historical term used by hearing people to identify a person who was deaf and could not speak. Its first appearance was in the code of Hammurabi, where this is an ancient set of laws during the 1700 BCE in the area of the near east. It also appears in the ancient Greek writing of the 7th century BCE. Generally it is said to be as linked to the deaf people, mainly within a historical context, to indicate deaf people who cannot speak, or have some degree of speaking ability, but choose not to speak because of the negative or unwanted attention atypical voices sometimes attract. Some times it also refers in chideing some people or to the people who is unreal able. The other reference to them is "semi-deaf" and "semi-mute". There are connotations of insensitivity to deaf people concerning these terms of reference and for this reason the prevailing terms are generally looked upon as insulting, inaccurate or socially and politically incorrect
