Arrange the steps for installing a desktop RAM module (DIMM) into a motherboard in the correct chronological order.

### Why this is right Compatibility must be checked before installation so the module fits the motherboard and works with the system. The computer must then be made safe before you handle components; only after inserting and securing the module can you check that it is seated correctly. ### The concept A **Dual In-Line Memory Module (DIMM)** is a removable circuit board that holds **Random Access Memory (RAM)**, the computer’s short-term working memory. The motherboard is the main circuit board, and its memory slots have keys that match the notches in compatible modules. Retention clips are the small movable catches at the ends of a slot; they hold the module in place when it is installed. Correct seating matters because the module’s contacts must connect with the slot for the computer to detect and use it. ### The order 1. **Confirm the module is compatible with the system.** This avoids trying to install a module that does not match the motherboard. 2. **Prepare the computer safely.** Power it off and disconnect the power cable before opening the case or handling parts; open the slot’s retention clips. 3. **Place the module in the appropriate slot.** Align its notch with the key in the slot, then press firmly until the clips snap into place. 4. **Check that the module is correctly seated.** Make sure it is even and held by the clips, rather than tilted or loose. ### Watch out Do not force a module if its notch does not line up with the slot key. The mismatch usually means it is turned the wrong way or is not compatible. ### Terms - **DIMM**: Dual In-Line Memory Module. A removable board that carries memory chips and fits into a motherboard memory slot. - **RAM**: Random Access Memory. Fast, temporary working memory used by the computer while it is running. ### Remember Check compatibility first, disconnect power before handling parts, and let the slot’s notch and clips guide correct installation.
