Categories of Electronics:

The electronic devices were formerly divided as Brown or White depending on the skills required to use them, repair them and based on their sizes.

Small/ Brown: If you remember seeing olden days black and white T.V, screens packed in huge wooden boxes with shutters. They would look like brown wooden cupboards from outside, so also most of the radios and cassette players of old times where encased in wooden boxes. Such wooden boxes were used since plastic was still not so common and economical in those days. Wood serves as a protecting case, produces good base for the sound, it is safe as it is bad conductor of electricity hence contains any electric shocks, was readily available and was widely used in electronic devices in those days and hence the small devices were called “Brown electronics”.
These devices are mostly not so bulky, comparatively less complex, and hence somehow easy to repair. T.V., D.V.D, woofers, cameras, Mobile phones and landlines, etc. come in this category. As a matter of fact people still like those radio cassettes and woofers which have wooden body and /or are colored like wood, for instance “Geepas” woofers are more popular in small woofer category around East Africa.

Major/White: Unlike T.V. screens and radio cassettes which were colored brown in olden days, most of the bulky, not easy to repair, devices were colored white, for instance Refrigerators, most of them are still colored white. Other examples are Washing machines, Water heaters/ Geezers, Electric stoves, etc. Repairing these devices needs specialized technical help, most of them even work on higher watts and consume more power. 

What are House hold Electronics/ Consumer Electronics?

Consumer Electronics: Wide range of easy to use electronic devices which are commonly and commercially available around most of the places in the world.

House hold: A place where a group of people / family live together

Electronics: A Device or appliance which works on the principle of flow of electrons (or charged particles).

Household Electronics: Devices, appliances or machines which work on principle of Electronics and are mostly used by people in their day to day lives. The purpose of using electronics could be anything from below:
·         For making our lives comfortable and easy (e.g. Fans, Lights, Electric showers, Vacuum   cleaners, Electronic stoves, Extension cables, etc)
·         For entertainment, leisure and relaxation (e.g. T.V., D.V.D., woofers, IPods, Mp3 players)
·         For getting valuable information from around the world and for communication (e.g. Radios, Mobile phones, Satellite decoders)
·         For reducing work load and finishing daily tasks faster, (e.g. Calculators, Computers, electric kettle, water heaters, etc)
·         For security (e.g. Security alarms, security lights, Door bells)
·         For improving the quality of life (e.g. Digital cameras, Refrigerators, Microwave Ovens)
·         For good health and sanitation (Electronic thermometers, shaving machines, flat irons)
