Answer: b) The Internet is designed to scale to support an increasing number of users.

Scalability is one of the most evident and significant characteristics of the Internet. Launched in the 1960s as ARPANET, the Internet was from the design on with a distributed and de-centralised structure which has facilitated a natural expansion. This design makes it possible for the network to support more and more users, devices and data traffic while continuing to support all these without necessitating a radical change in the design of its key parts. The scalability of the Internet is made possible through several technologies and protocols for instance the TCP/IP suite which support customizable routing and addressing of pathways. Also, the Domain Name System (DNS) and Content Delivery Networks (CDNs) offer to Internet to meet increasing loads. This scalability has been important in the Internet developing from a minor research network to the present world-wide web connection system that unites billions of clients and gadgets across the globe.
