What are major types of networks and explain?

Correct Answer: One of the main causes of congestion is that traffic is often busy If hosts could be made to transmit at a uniform rate, congestion would be less common Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate This is called traffic shaping

Correct Answer: Classless Inter-Domain Routing

Correct Answer: Ping Netstat

Correct Answer: Automatic Private IP Addressing for small network if u see something default automatic numeric values entered in a device that is attached you can see someone novice has done that using APIPA

Correct Answer: the layer that establishes ,manages and terminates the session between two communticating devices

Correct Answer: The address resolution protocol(ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address

Correct Answer: FDM is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted

Correct Answer: WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing involve light signals transmitted through fiber optics channel

Correct Answer: TDM is a digital process that can be applied when the data rate capacity of the transmission medium is greater than the data rate required by the sending and receiving devices

Correct Answer: The internet address( IP address) is 32bits that uniquely and universally defines a host or router on the internet The portion of the IP address that identifies the network is called netid The portion of the IP address that identifies the host or router on the network is called hostid
