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. __________________________

What are the advantages and disadvantages of connectionless protocols in comparison to connection-based protocols?

2. Subnetting a subnet or using variable-length subnet mask (VLSM) was designed to maximize addressing efficiency. You are required to subnet, based on the number of hosts, including router interface and WAN interface and WAN connections for the following scenario: •Toronto: 60 host addresses •Montreal: 28 host addresses •Ottawa: 12 host addresses •Vancouver: 12 host addresses •WAN1: 2 host addresses •WAN2: 2 host addresses •WAN3: 2 host addresses Using the given address block of 192.168.15.0/24, you can design an address scheme for the network to meet its requirements and save potential addresses. The data for Toronto is given to help you to fill the remaining all other columns. Name Toronto Montreal Ottawa Vancouver WAN1 WAN2 WAN3 Required no of addresses 60 28 12 12 ~~ 2 2 2 Subnet Address 192.168.15.0 Address Range .1 - .62 Broadcast Address .63 Network/ Prefix 192.168.15.0 /26 19

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