When did the gulf stream oil spill begin?
There was no 'gulf stream oil spill' per say. Rather, the 2010 BP Gulf of Mexico oil spill has reached the Gulf. This spill started on 2010 April 20, reaching the gulf stream approximately in August.

What are used to notify a sending device that a stream of data packets has or has not been received?
ACK packets, NAK packets, or a packet timeout happens at the sending device.
What is a firewall used for?
A firewall is usually placed in front of a group of machines and its primary function is to control communication from and to this group of machines. Communication between two machines over the Internet is a stream of packets (datagrams) send in both directions. The firewall examines all packets that is about to be routed through the machine and, based on a set of rules, determines if the packet is allowed to pass through the machine or not. This functionality is often referred as a packet filter. The secondary function of a firewall is to modify the packets passing through the firewall. This is called Network address translation (NAT), as the modifications usually applies to either sender or receiver information contained in the packets. NAT can for example be used to allow machines without a public addressable Internet protocol (IP) number, to access the Internet through a firewall, by using the IP-number of the firewall as the sender identification. This is also called ip masquerading, as it disguises the address of the machines behind the firewall. www.goldstardailynews.com
What is the definition of stream gradient?
A) the distance traveled by water in a channel times a drop in elevation b) the drop in elevation of a stream divided by the distance the water travels c) the water pressure at the bottom of the stream divided by the stream's width d) the increase in discharge of a stream per unit drop in elevation

wave-particle duality
How is data passed in packets?
The details vary enormously from protocol to protocol, but the basics are the same for all of them. A stream of data is split into packets, the packet has a header which contains (amongst other things) the destination for the packet. The network uses the destination address to deliver the network to the correct destination.
How can you make udp reliable?
Reliable UDP is impelemented much like how TCP is implemented. With each packet you have assign it an id. That id tells you its sequence with respect to the stream, and acts as a unique identifier if it gets dropped. On the reciver side you recive these packets. After a set wait period (calculated based upon latency and other factors) you send the sender the packet ids which you have recived. You can''t send the packets you haven''t recived becuase you dont know if either there weren''t any packets sent or they all got dropped, so you send the ones which you have recived. Of course its possible this ack packet could be loss, if so then on the senders side, a complete resend will occur. So assuming the ack is not lost, the sender recived the list of sent packets. It then sends packets which were loss. That''s the gist of it. If you use this reliable UDP stream with respect to packet boundaries, you can ignore the stream consistency and use the packets as they arrive. It will give you lower transcational latency with respect to packet loss. If not then you will suffer the same behavior which TCP streams have when there is loss, high latency. That is if you want to use the reliable UDP like a data stream, the sequenece must be complete before you can send it to the application. That means waiting on packet resends. If that is the case, might as well go with TCP. However if you know that the packets are independent of each other, and can be processed as they come in, you don''t need to wait on resends. Good Luck
How do you calculate the bifurcation ratio?
You add the number of streams that branch off the main stream which is the first order then you add the number of streams branching off that stream whih becomes the 2nd order and the sum of the no. of stream orders divided by the number of streams gives the bifurcation ratio.

What is the Protocol used in Cisco Network Voice?
There are several protocols that are used for VoIP. The SiP, or H.323 protocol can be used for signalling and to establish a connection. UDP/RTP packets then generally carry the actual voice stream.
Is the thames river divided up into regions?
It is not divided into named regions. But, like all rivers, it changes along its length - from a small stream to a much wider river. It does not start in a mountain so it is never fast flowing.
A meander generally characterizes which type of stream steep stream a young stream a narrow stream or a mature stream?
A mature stream.
