There are situations, called hazards, that prevent the next insturction in the instruction stream from executing during its designated clock cycle. hazards reduce the performance from the ideal speedup gained by pipelining.

There are three classes of Hazards:

1. Structural hazards: It arise from resource conficts when the hardware cannot support all possible combinations of instructions simultaniously in overlapped execution.

2. Data Hazards: It arise when an instruction depends on the results of previous instruction in a way that is exposed by the overlapping of instructions in the pipeline.

3.control hazards. it arise from the pipelining of branches and other instructions that chage the PC.

The U.S. e-commerce giant, Amazon has been awarded a patent for launching a giant flying warehouse that would acts as a launch pad for drones to deliver items within minutes.The patent reveals plans for setting up an “Airborne Fulfillment Center” (AFC) such as an Airship or Blimp, floating at an altitude of around 45,000 and stocked with lots of products especially in area where the demand for certain items is expected to be high. When a customer places an order, a drone or unmanned aerial vehicles (UAV) will fly down and deliver the package. The patent claims that this would require little or no power because the drone would be gliding down rather than having to take off and land.

Lead caulked joints are used for laying Earthern ware pipes.

Earthenware is fired at 1900 degrees Fahrenheit, much lower than stoneware. The result is porous pottery that is not as strong as stoneware or porcelain pottery pieces and is cheaper than stoneware.
