the upstream of a pipe is its inlet and the downstream is its outlet
****if your talking about broadband/internet speed*****downstream is taking information from the internet.(downloading) upstream is putting info on the internet uploading
The total process of a the refining business starts at the oil field or gas field and runs all the way to the sending of processed hydrocarbon to a final user.
Upstream applies to the operation of exploration, drilling, hydrocarbon production, and transmission via truck, rail or ship or pipe line to the refinery intake valve.
Downstream includes all work done at the refinery, distillation, cracking, reforming , blending storage, mixing and shipping.
The case of heavy oil processing (oil sands etc.) and gas plant operation tend to cross the boundaries somewhat. Most are regarded as upstream operations even though downstream type operations are part of the processes. The production of chemical side products at gas plants (e.g. sulfur) is not generally segregated as a "Chemical Plant" operation.
Additional hydrocarbon production operations such as saddle plants which remove a component from pipeline gas are generally lumped with upstream.
Upstream is the production of iron and steel whereas the downstream sector is the production of mid stream semi finished products like blooms, billets,slabs and ingots and the final products like pipes, tubes etc
The difference between upstream and downstream in a river is how the water flows. When you walk along the river and follow the current, you are going downstream. When you go against the current , you are going upstream.
In the oil and gas industry, the term "upstream" refers to the ever-rising value of oil for the general consumer but not the big companies. The leaders of the gas industry can set the price at a level of their own choosing.
what is difference between dynamic and volumatic compressor
A proxy supplies internet data to your client if configured to do so. An upstream proxy proxy provides the Internet pages to your proxy.
what is difference between mild steel and stainless steel
Both are same no difference Both are same no difference
DSL speeds vary, depending on the type and condition of the medium. If your house is serviced by fiber optics, then the speed is mostly dependent on how much money you would like to spend, since mostly all speeds are attainable. If your house is serviced by copper, then the most important parameters are the length of the loop from the central office and the amount of bridgetap on the phone line. Without getting too technical, then, the standard speeds are 1.5 Mbps downstream and 384 kbps upstream. I work as a technician for the largest DSL provider (take a guess who) and these are the speeds that we install 9 times out of 10. As fiber optics are replacing copper, and the price of packages fall, higher speeds will become the norm by 2008/2010. As an educated guess, the new standard speeds will quickly become between 6 Mbps and 12 Mbps downstream, with upstream speeds about 1/4 of that. Cheers!

Upstream deals with primary prevention while downstrem deals with secondary and tertiary prevention.

Simply Upstream is the management of raw material, from logistics to storage and finally processing, and Downstream is the management of finished products from storage to outbound logistics, marketing and sales and finally customer service.
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
downstream and upstream
Upstream will be the closest to the engine, and are used to sense the air/fuel ratio and tell the computer how much fuel to inject. Downstream sensors are used to verify the upstream sensors and convertors are functioning correctly, so they are located after the convertors.
assembly upstream and downstream in ammetres
Upstream is where the flow is coming FROM . -Downstream is the direction it is going to.
Downstream
From what I understand , the oxygen sensor ( s ) upstream of the catalytic converter is used in the control of the air / fuel ratio . The oxygen sensor downstream of the catalytic converter is called a catalyst monitor and monitors the efficiency of the catalytic converter
The upstream of a river is its mouth, AKA, the opening to the ocean, and everything in between. Downstream is the source, AKA the "beginning", such as a lake, and everything in between.To put it simply:A RIVER:(Mouth)=--------------------------------------------------------------------------------0 (Lake) Downstream
