Why CPUs Need Heat Sinks?

Heat sinks are components that are responsible for transferring heat from a solid material to air or liquid medium. They increase the contact surface area to make heat transfer faster.

Modern computers have CPUs as their heart that processes all the data. Processors become hot very quickly but require cooling to function properly. This is what the heat sinks are for.

Computer hHeat Sinkeat sinks are attached to the processors to collect heat from them and transfer the collected heat to air or liquid media. Fans or thermal cooling solutions are attached to the heat sinks to take the heat away from them so they can provide necessary cooling to the processor.

EPROM Chips Importance And Uses

EPROMs are Erasable programmable read only memory chips. This device is mainly used as a memory to store a small amount of data. Some micro-controllers use this memory to store its program contents. EPROMs must be erased before they are rewritten. This is usually done by exposing them to UV light through the window provided on the chip. Exposure of the chip to UV light for longer periods of time can over erase the memory cells of EPROM which may not be readily fixable. Modern EPROM chips have a capacity ranging from few KB's to nearly 8 MB of storage space. To erase EPROM's, they must be removed from the circuit. So, this is not practical in many applications these days. Some versions of Intel 8048 microcontrollers used EPROM in their processors. In the modern world, EPROM chips are at the end of their existence as they are being succeeded by newer type of memories which are practically easy to implement like flash memory.
