Ballistix Memory from Crucial is high end gaming memory with different colours to look better in your gaming rig. I highly reccomend Crucial and have used their products for decades now take a look or choose the normal less colourful ram, and read about the 10 year warranty on most memory!
SODimm memory is what you need for your Laptop - The number after the version so DDR4 is the type, -2400 is the speed of the memory
UDimm is the standard memory for Desktops and Computers, the U in the name means unregistered memory it is typically cheaper than RDIMM which is registered memory and ECC error correction memory which is usually only for servers.
