Combination of two or more networks are called
a). WAN
b). MAN
c). LAN
d). Internetwork
The correct answer and explanation is :
The correct answer is:
d) Internetwork
Explanation:
An Internetwork refers to the connection of multiple networks, such as Local Area Networks (LANs), Wide Area Networks (WANs), or Metropolitan Area Networks (MANs), to enable communication between devices across different network types and locations. An Internetwork is essentially a network of networks, and it allows data to be exchanged across different physical or logical network architectures.
In the context of computer networks, internetworking is a process where multiple networks (like LANs or WANs) are interconnected to form a larger, cohesive system. Routers, switches, and gateways are typically used to facilitate this interconnection, allowing seamless data transfer and communication between disparate networks.
An Internetwork usually relies on common communication protocols, such as TCP/IP (Transmission Control Protocol/Internet Protocol), which ensure that devices on different networks can understand and communicate with each other. The Internet itself is a global example of an Internetwork, consisting of millions of interconnected networks that enable worldwide communication.
Comparison with Other Network Types:
- WAN (Wide Area Network): A WAN connects devices or networks across large geographical areas, often spanning cities, countries, or even continents. It is a type of network, but not specifically a combination of multiple networks.
- MAN (Metropolitan Area Network): A MAN covers a larger geographical area than a LAN, typically within a city or a large campus, but it doesn’t represent a combination of different network types.
- LAN (Local Area Network): A LAN connects devices within a small geographical area like a home, office, or building. It is typically a single network, not a combination of multiple networks.
Thus, an Internetwork is the most accurate term to describe the combination of two or more networks.
