They are either plated with tin or gold.

memory module edge connectors are typically gold plated copper printed circuit traces, the gold provides corrosion resistance while the copper underneath provides electrical connections to the memory chips mounted on the module (and is much cheaper than gold)the slots the memory modules install into are typically gold plated phosphor bronze springs, the gold provides corrosion resistance while the phosphor bronze (an alloy containing copper, zinc, tin, iron, and phosphorus) underneath provides both electrical connections and a strong springiness that plain copper (a very soft weak metal) could not, ensuring a solid physical/electrical contact with the memory module's contacts.
Clean the module edge connectors with a soft cloth or contact cleaner. Blow or vacuum dust from the memory sockets. Also, to prevent corrosion in the connectors inside the memory slots is by matching tin leads to tin connectors and gold leads to gold connectors to prevent a chemical reaction between the two metals, which can cause corrosion.
There are many examples of conductors such as electricity. Metals and liquids can also be considered a type of conductor.
A meta called athropod it can transform phone memory
Joysticks are examples of input devices used for controlling video games or programs, while memory metals, like Nitinol, are examples of materials that can "remember" their original shape and return to it when subjected to certain conditions.
Yes, microwaves can contain small amounts of precious metals, such as gold and silver, primarily in components like circuit boards and connectors. These metals are used for their conductive properties and resistance to corrosion. However, the quantity is typically minimal, so the recovery of precious metals from microwaves is usually not economically viable on a large scale.
Metals in a computer include aluminum (used in the casing), copper (wiring and heat sinks), gold (connectors and components), silver (printed circuit boards), and various rare earth metals in small quantities within the electronic components.
