What socket type is soldered to the motherboard, along with the CPU?a.PGAb.FCLGAc.SPGAd.BGA

To determine which socket type is soldered to the motherboard along with the CPU, let's analyze the options provided:

1. PGA (Pin Grid Array): This type of socket has pins that fit into holes in the CPU. It's not soldered to the motherboard; the CPU can be removed.

2. FC-LGA (Flip-Chip Land Grid Array): This socket type uses land pads where the CPU makes contact. While it's more secure, it's designed for easy removal and not typically soldered.

3. SPGA (Scalable Pin Grid Array): Similar to PGA but allows for a larger number of connections. Like PGA, it’s not soldered to the motherboard.

4. BGA (Ball Grid Array): This socket type involves solder balls underneath the CPU that are soldered directly to the motherboard, creating a permanent connection.

Conclusion

The correct answer is d. BGA as it refers to the socket type that is soldered directly to the motherboard.
