Final answer:
It may be better to install memory cards before installing the CPU in some situations to provide easier access to memory slots and ensure proper configuration of memory settings in the BIOS or UEFI firmware.
Step-by-step explanation:
In some situations, it may be better to install the memory cards before installing the CPU in a computer. This is because when you install the CPU, you may need to access the memory slots on the motherboard, and installing the memory cards first can provide easier access to these slots. Additionally, installing the memory cards before the CPU ensures that you can properly configure the memory settings in the BIOS or UEFI firmware, which is crucial for the computer to recognize and utilize the memory.
