These are various types of connectors, for various types of devices.
Try http://images.google.ca and search for "M.2", to get images of the M.2 memory-stick, and the matching socket on your motherboard.
Or, search for "internal SSD" to get images of the SATA-connector and power-connector.
Or, search for "PCI-e". Some of those style of adapters have memory-chips that emulate a disk-drive.
Or, support a local business -- take your computer to a local "owner/operator" computer store, and get help purchasing something that will be compatible with your computer.
