The Evolution of Electronics

Since the beginning of 19^th century the discovery of electricity has lead to various other inventions and innovations, Simpler forms of electronic devices like Radios evolved over time into Radio cassette players, Radio cassettes which can play Flash / SD cards and now even available with D.V.D and stereo systems. With increasing innovations and reception by populations the field spontaneously took shape of an industry which has multibillion dollar turnover around the world.

The applications of Electronics are now expanding much more than just in sectors of entertainment, communications, office works and auto-electronics to Hospital and Health sectors, Infrastructure development, Defense and Security, GPS and Space research, etc.

The electronics of these days are now super machines having loads of specifications, features, functions, utility and are more adaptable to mobility than ever before. For instance a portable Screen/ D.V.D, commonly known as “Coby” locally is a very good example for the evolution of electronics and can be termed as a “value for money electronic device” with wide range of applications as below:

·         It’s a color T.V screen supporting different systems and formats of video

·         D.V.D, V.C.D, Audio c.d. player

·         F.M. radio receiver

·         Satellite broadcasting receiver (can receive U.B.C, K.B.C, NTV depending on area) comes with small satellite antenna

·         MP3 player : can play Flash disks, Memory cards (SD and Micro SD for mobile phones)

·         Has Video game functions and mostly comes with special remotes and c.ds for games

·         Has Copy / Paste functions for transfer of MP3 files

·         Supports viewing of digital photographs

·         Has rechargeable battery (extremely useful in the days with power cuts)

·         Is portable and easy to travel with

·         Is remote control operated

·         Has two type of charging systems i.e. you can charge it on power (A.C.) or on motor car lighter sockets during travel and even directly on batteries (D.C.); hence can even be used in locations where there is no Electricity.

·         It can be connected with external T.V. screens, woofers and decoders.

·         Some models even come with rotatable screens which can turn 180 degrees, ear phones and special pouches for hanging them in motor cars.

·         It also comes in various colors, styles and sizes.

·         It’s a “value for money” purchase because the cost of this device is much less than buying a 14’ color T.V + a D.V.D player.
