Hello this is what i found for you Sedimentary rocks are formed when sediment is deposited out of (air, ice, wind, gravity, or water flows) carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area. Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are 'erosion', 'weathering', 'dissolution', 'precipitation', and 'lithification'.

"Yes,  There are certain electronic chips that are programmed at the manufacturing plant to make the devices work properly. But if this chip becomes infected with a virus, the device will never be able to function properly again. The device would need to be de-soldered, replaced the chip and resoldered the new chip. This takes a lot of time and money, especially if your device is already a few years old. Then the price to be able to repair the device would be almost that of buying another new device"..

Sedimentary rocks are exogenous rocks (while igneous rocks are endogenous), that is to say formed on the surface of the Earth, and their genesis depends on very many factors such as the initial nature of the disintegrated and altered materials, the types of weathering, mode of transport, deposit zone, they most often constitute stratified deposits in superimposed beds (strata). As for their formation, it is necessary to distinguish 1) - detrital sediments, the most abundant which correspond to assemblies of varied debris, resulting from pre-existing rocks in general united between them by a cement of chemical or biochemical origin 2)- The physico-chemical (or biogenic) sediments which testify to chemical balances achieved under conditions of external T and P; organic rocks such as petroleum are special cases. Some categories of sedimentary rocks: detrital rocks pyroclastic rocks carbonate rocks siliceous rocks salt rocks, etc.
