Telecommunications, jointly known as telecommunication, is that the exchange of knowledge over very important distances by electronic suggests that and refers to all or any or any varieties of voice, data and video transmission. this will be a broad term that encompasses a sensible vary of knowledge transmission technologies like telephones (wired and wireless), microwave communications, fiber optics, satellites, radio and television broadcasting, the net, and telegraphs. A complete, single telecommunications circuit consists of two stations, each equipped with a transmitter and a receiver. The transmitter and receiver at any station is additionally combined into one device called a transceiver. The medium of signal transmission square measure usually via electrical wire or cable (also known as "copper"), fibre, attractive force fields or light-weight. The information can be published in our peer-reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. The impact factor plays a major role in a particular journal. Journal with a higher impact factor is considered to be more important than other ones.
