Memory Sockets

The picture above is of 4 DIMM sockets. DIMM sockets are where the computer's RAM, (or Random Access Memory), is installed. DIMM stands for Dual Inline Memory Module. The reason it is called "Dual" is because both sides of the memory module have completely separate connections from the other side of the module. On the older SIMMs, (or Single Inline Memory Modules), both sides were connected together at each contact point on both sides of the module. Below is a partial picture of a memory module's little gold contact points.
