Question 2: What best describe the following : A collection of computer networks interconnected together__________________ A network in which small chunks of data are passed through the network from node to node, and at each node the entire data chunk is received, stored briefly, and then transmitted to the next node IS A PACKET SWITCHING NEWT WORK This protocol model was developed by the International Organization for Standardization as a model for a computer protocol architecture and as a framework for developing protocol standards. ________________________ A device is used to connect different types of networks. __________________________

Computer Networks - Internet Architecture & Application Layer Please answer the question   Someone suggested to use a local file called hosts.txt on each machine instead of DNS. Discuss the advantages (at least 2) and disadvantages (at least 2) of such suggestion. What is ‘saw-tooth’ behavior in TCP, and what is causing it?

The industry currently favors connection-based protocols, so please provide a succinct explanation of the advantages and disadvantages of connectionless protocols.

The benefits and drawbacks of connectionless protocols must be weighed against those of connection-based protocols.

What is the rationale behind the requirement for a private network address? Is it possible for a datagram containing a private network address to be transmitted over the public Internet in its entirety? Explain?

Consider the advantages and disadvantages of connectionless protocols in comparison to connection-based protocols.

Weigh the benefits of connectionless protocols against those of connection-based ones.

Comparing connectionless protocols to connection-based protocols, as well as connection-based protocols to connectionless protocols, should be subjected to a cost-benefit analysis.

Task NW29. UDP is the simplest transport layer communication protocol. It contains a minimum amount of communication mechanisms. It is considered an unreliable protocol, and it is based on best-effort delivery services. UDP provides no acknowledgment mechanism, which means that the receiver does not send the acknowledgment for the received packet, and the sender also does not wait for the acknowledgment for the packet that it has sent. An end system sends 50 packets per second using the User Datagram Protocol (UDP) over a full duplex 100 Mbps Ethernet LAN connection. Each packet consists 1500B of Ethernet frame payload data. What is the throughput, when measured at the UDP layer? Task DS30
