Precipitates can form when two soluble salts react in solution to form one or more insoluble products - as discussed in the famous example below. The insoluble product separates from the liquid and is called a precipitate. Precipitates can also form when the temperature of a solution is lowered.
When the processor needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from or writing to main memory.
The lines on the motherboard are physical addresses to a device which carries instructions to the central processing unit which is the brain or scheduler of the computer system. Central Processing Unit (CPU) The central processing unit (CPU) or brain of the computer system processes complex functions in the system. The CPU chip receives instructions from the system board and software applications. Today's CPUs can process data measured in milliseconds.
