Circuit switching is the realtime connectionoriented system. It mentions circuit switching advantages or benefits and circuit switching disadvantages or drawbacks. Selecting a path that data must take out of the available options is called switching.
In circuit switching, a route and its associated bandwidth is reserved from source to destination, making circuit switching relatively inefficient since capacity is reserved whether or not the connection is in continuous use. Switching as computer networks became more pervasive, more and more data and also less voice was transmitted over telephone lines.
