Electronics is a vast stream. The subject is pervasive in itself. Electronics are the primary source of almost everything that is happening today. The whole working of the items is dependent mainly on the electronics base. In our daily lives, we can see uncountable examples of the number of electronics used around us. From our environment itself, we can see how electronics can find their use in so many work departments. Human beings are slowly becoming addicted to the use of electronics in their lives. They have become almost dependant on the machines for their work. For example, the computer is the most commonly used machine, which is the best illustration of electronics in our lives. People have started being dependent on these machines to a large extent. All the work that was earlier known to be done by the people is now seen as to be done by the various devices and also the computer. Such is the help provided by the electronics to the people in their lives.
