A path through which information is transmitted from one place to another is called communication channel. It is also referred to as communication medium or link. The twisted pair wire, coaxial cable, fiber optic cable, microwave, satellite etc. are examples of communication channels.In a communication channel, data is transmitted in the form of signals (analog signal). The data transmission is measured in bandwidth. The bandwidth will be higher if more signals can be transmitted. Actually, the bandwidth measures the amount of information that can be transmitted through the media within the given period of time. For analog signals, bandwidth is represented in hertz (Hz). It means number of signals transmitted per second. For digital signals, it is represented in bits per second (bps). Different transmission media have different bandwidths. The higher the bandwidth of the transmission media, the more information can be transmitted.Types of Communication Channel:The communication channel or media is divided into two types.1. Guided Media.2. Unguided Media.1. Guided Media:In guided communication media, communication devices are directly linked with each other via cables or physical...more

If you can, use a bain-marie. Alternatively, put the wax a separate container and place that container a saucepan with water, heating it on a cooking hob.If you chop the wax into chunks, it will melt more easily.
