There is no doubt that electronics and related equipment have an impact on nearly every facet of life today. Everything from music to recreational equipment, from medical diagnostics to telephones rely upon components built with and containing electronics. Electronics equipment consists of input, processing and output modes, often accomplished by the use of circuit boards dedicated to one specific task.
The study of the movement of electrons, or electronics began with the inventions of telephones and telegraphs and has steadily gained more influence since that time. With the invention of the radio, however, electronics took a giant leap in development and has been growing at the same or an advancing rate since. For example, radio was followed by television. At the same radio was becoming more sophisticated as smaller units known as pocket radios were invented.
By adding headphones to a portable radio–music, news and entertainment the listener can listen without any outside noises entering into the listening zone. This makes entertainment very portable so that music and even games can be enjoyed while on the move.
Another type of portable entertainment is contained on many of today’s mobile phones. A mobile phone is no longer just
to talk to a friend while on the move. A mobile phone is used for sending voice and text messages. You can access the internet to receive and send email messages and to browse the web. Your mobile phone will allow you to take digital pictures, both still and video and to send those images to friends or to store them on the phone or on a computer. A mobile phone can play your favorite songs and even take pieces of those songs and make a ring tone from them. You can download the songs from the internet or from friends’ copies. Of course, with Bluetooth capability, you can use all the features of a mobile phone without disturbing those around you.
Music players such as IPod or MP3 players can play music choices downloaded from your computer onto a memory card. One of these memory cards is small in size but can hold literally hundreds of songs so you always have your favorites with you. There are several web sites where you can choose from play lists in order to purchase a single track or album that you can then download to your music player.
