protocols?
There are different standards and protocols assigned to do different things. It is not possible for a single
standard or protocol to do all the tasks that are required within a network. Another reason can be the
incompatibility. There are different devices (e.g. mobile phones, computers, laptops) and networks
(such as Local Area Network, Wide Area Network). There is not a particular standard or protocol that
can establish communication or send information between every single device or network.
