Electronics engineering, or electronic engineering, is an electrical engineering discipline which utilizes non-linear and active electrical components (such as semiconductor devices, especially transistors, diodes and integrated circuits) to design electronic circuits, devices, microprocessors, microcontrollers and other systems including VHDL modelling for programmable logic devices and FPGAs. The discipline typically also designs passive electrical components, usually based on printed circuit boards.
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use.
Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object.
Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information.
An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems
Commercial practice is a career which prepares you to tackle the various aspects of general office duties. It is available as a diploma course. The aim of a diploma in commercial practice is to prepare students from an early age to join any office in various capacities.
The job is either connected to front office management or to promotion and sales. When you specialize in commercial practice, you work towards the sale and supply of products to the consumers either directly or indirectly. You will have to have a wide spectrum of knowledge including secretarial expertise, a skill with computer and basic knowledge of data entry and analysis.
