Statement A: A network consisting of 'n' nodes and 'e' elements can be completely analyzed from (e - n + 1) mesh equations or (n - 1) node equations - This statement is true. In network analysis, the number of independent equations required to completely analyze a network can be determined using mesh and node equations.
Statement R: The number of mesh equations plus the number of node equations is equal to the number of elements in the network - This statement is also true and provides a correct explanation for Statement A. The number of independent mesh equations required for network analysis is equal to the number of elements minus the number of nodes plus one (e - n + 1). Similarly, the number of independent node equations required is equal to the number of nodes minus one (n - 1). When these equations are combined, they cover all the elements in the network, as stated in Statement R.
Therefore, the correct answer is (A) Both A and R are true, and R is a correct explanation of A.

Multiple interconnected devices, such as computers, routers, and servers, that allows for the sharing of information and resources.
(B): It enables communication and collaboration between users, allowing them to share files, access shared printers and other peripherals, and communicate through email or instant messaging.
(A): Networks can be local, connecting devices within a small area like a home or office, or they can be wide area networks (WANs), connecting devices across larger geographical areas.
(B): Networks can be wired, using physical cables to connect devices, or wireless, using radio waves to transmit data.
(A): The internet is a global network of networks, connecting millions of devices worldwide and allowing for the exchange of information on a massive scale.
(B): Network security is a critical aspect of any network, as it aims to protect the data and resources from unauthorized access or malicious attacks.
(A): Networks are essential in today's digital age, facilitating communication, information sharing, and access to resources, and enabling businesses to operate efficiently and individuals to connect and collaborate.
