A processor can be a plug and play or inserted. The difference lies in the way the bolts (or screws) are tightened to attach the processor onto the motherboard, as well as how much contact it has with that board. A “plug-and-play” CPU is soldered into a socket on the motherboard and screws, clips, slides, or locks over it to secure it. These CPUs can be removed just by powering down your computer first and then removing them from their mounting brackets. Regular processors have been inserted because they aren’t soldered directly onto a chip’s logic board but instead use pins on either side of its jacket to fixate its position through slots preinstalled at specific points along aluminum rails for each one.
