Consumer behaviour is the study of individuals, groups, or organizations and the processes they use to select, secure, use, and dispose of products, services, experiences, or ideas to satisfy their needs and wants.

It is also concerned with the social and economic impacts that purchasing and consumption behaviour has on both the consumer and wider society.

Consumer behaviour blends elements from psychology, sociology, social anthropology, marketing and economics, especially behavioural economics.

It examines how emotions, attitudes and preferences affect buying behaviour.

Characteristics of individual consumers such as demographics, personality lifestyles and behavioural variables such as usage rates, usage occasion, loyalty, brand advocacy, willingness to provide referrals, in an attempt to understand people's wants and consumption are all investigated in formal studies of consumer behaviour.

The study of consumer behaviour also investigates the influences, on the consumer, from groups such as family, friends, sports, reference groups, and society in general.

Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.

The ability of computers to follow a sequence of operations, called a program, make computers very applicable to a wide range of tasks.

Such computers are used as control systems for a very wide variety of industrial and consumer devices.

This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones.

The Internet is run on computers and it connects millions of other computers.

A brand (or marque for car model) is a name, term, design, symbol, or other feature that distinguishes one seller’s product from those of others.

Brands are used in business, marketing, and advertising.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.
