Problems with your PRAM and NVRAM can result in user settings being lost, causing issues like connectivity problems and resolution changes. NVRAM does not require a battery to retain its data, but it may occasionally need to be reset to resolve issues related to booting or network connectivity. In some newer Macs, PRAM has been replaced by NVRAM (Non-Volatile Random Access Memory), which also stores system settings and preferences. When the computer is powered off, the PRAM continues to draw power from the battery, which lets it retain its data. PRAM works by using a small amount of battery power to maintain the stored settings. This preserves system settings between sessions, even if the computer is unplugged or experiences a power outage. Unlike RAM (Random Access Memory), which is volatile and loses stored data when you shut down your computer, PRAM is non-volatile, so it doesn’t clear its data when you turn off your computer.
