History of The Internet Phillip Johnson The Internet is a worldwide connection of thousands of computer networks. All of them speak the same language‚ TCP/IP‚ the standard protocol. The Internet allows people with access to these networks to share information and knowledge. Resources available on the Internet are chat groups‚ e-mail‚ newsgroups‚ file transfers‚ and the World Wide Web. The Internet has no centralized authority and it is uncensored. The Internet belongs to everyone and to no

Assume all devices are using default configurations. How many subnets are required to address the topology that is shown? 1 *3 4 5 7 Two routers are connected via their serial ports in a lab environment. The routers are configured with valid IP addresses‚ but they cannot ping each other. The show interface serial0/0 command shows that the serial0/0 interface is up but the line protocol is down. What could be the cause of this problem? The no shutdown command has not been applied to the interfaces

(VoIP) is the assembly of voice into IP data which can be transmitted over an IP network to an addressable (IP address) destination. VoIP calls are packet switched while analog calls are circuit switched. Packet switched data are data that can be routed through different routes on a network to reach a destination while circuit Switched is a connection where a physical path is dedicated between two end points [3]. [5] Describe VoIP as the transport of voice over IP based data networks like WAN‚ MAN
