Question

Which of the following are true?

i. a local area network (lan) connects other lans and bns located in different areas to each other and to wide area networks in a span from 3 to 30 miles.
ii. as the demand for more and more network applications grow; host-based computing becomes the best solution.
iii. middleware is the software that sits between the application software on the client and the application software on the server.

Answer 1

The true statement among the options is that middleware is software that enables communication between client and server applications. LANs do not typically span 3 to 30 miles, and increased network application demands require distributed, not host-based computing solutions.

Step-by-step explanation:

Of the following statements, the third one is true: Middleware is the software that sits between the application software on the client and the application software on the server. This software effectively allows the two to communicate and function together, playing a crucial role in networked communications and distributed computing systems.

The first statement is not true as a Local Area Network (LAN) is typically contained within a single building or campus and does not span distances between 3 to 30 miles, which is more characteristic of Metropolitan Area Networks (MANs) or Wide Area Networks (WANs).

The second statement is also inaccurate because increased demand for network applications requires more distributed computing, where processing is spread across multiple systems, rather than host-based computing which centralizes processing on a single server and is less scalable.
