Vint Cerf has described the InterNet as a homogenous network that connects heterogeneous
computers. What did he mean by that?
The network has the same protocols but connects different devices
What is Melcalfes Law
The value of telecommunications networks is proportional to the square of the number of connected users of the system
Where geographically are the majority of internet users located
ASIA
Concerning the internet with what are mobiles helping
Global Internet
In design terms what differentiates the internet from earlier networks such as the telephone and telegraph networks
Wired connections to wireless differentiates the internet from earlier networks
Was there a particular logic in Vint Cerf's choice of a 32 bit address space for IP Address
No
How do digital signatures relate to closing an important vulnerability in the DNS system
Signatures can bind domain and Ip Addresses
What is a sensor network a nd an example
its a network made up of sensors that monitor outside or phyiscal conditions like temperate. Example is a smart grid
What does Vint Cert describe as one of the hardest problems that he can imagine
the hardest problem was finding when a certain configuration went dead/bad and how to fix it and how to design a system that was smart and knew where the errors were
Why is Cloud collaboration Important
Cloud collaboration can increase sharing of information between everyone, you dont have to phyiscally go anywhere to give people anything.
How does vint cerf describe the job that his internet design did with broadcast? Specfically what was the problem.
Thye did a bad job with broadcast, you were very limited with the broadcast cause you can only talk with 1 person instead of a ton of people. You couldnt have a broadcast with serveral people at A Time.
How does Vint Cerf describe the job that his Internet Design did with broadcast? Specifically, what was the problem?
They were inefficient.You were only limited to talking to one person at a time
What is strong authentication? Why is the lack of an issue?
Authentication verifies if a network or the person accessing the network is safe and allowed. Lack of this allows breaches in data, data leaks
In an internet context, what is an overrun problem?
A overrun problem is when you have a self organized network with too many nodes and the nodes are bad. they over run the "good nodes" and take over the devices the good ones have. Theres a problem on determining if a good node is a bad node and if a bad node is a good node impossible to tell which is which.
What does cerf cite as a problem with the internet and copyright
information can be copied and distrubuted easily if it is on the internet. Theres no way to ptotect as copyright on the internet, since once its uploaded it is there forever.
What does cert mean when he talks about rotten bits? Give an example.
INformation created in a certain formation can not be read by other types of software. this is a problem because no one knows how software was today in the future. Example: You cant open mac files on a windows, since it cant be interpreted
Briefly describe the interPlanetary Internet. In your description describe how this solves the point to point interPlanetary Communications problem
The planetary network can communicate and create a networking enivorment with multipe devices across the entire galaxy. Satelites would send information between earth and other planets. Spaceships can send information to other spaceships and this could make an fully networked system in the solar system.
In an internet context what is common carriage? What implications does this have for internet billing.
Everyone is entitied to the same speed and internet services. Everyone is equal and everyone is under the same terms and conditions.
What does cerf mean when he says that in the future the network will disappear
Network will become a part of the outside world.Everything will be network capable.
