Computer Operation
How has CMOS memory change over the years?
CMOS memory has been changed from analog to digital, the speed has increased. CMOS has also made changes in the regards to noise reduction. Over the years, CMOS has evolved into using the EEPROM (CMOS, 2013).
Has the size of the CMOS memory increased, decreased, or stayed the same?
The size of the CMOS memory has pretty much stayed the same because there is really no need to increase the size. The typical size is still 512 bytes. It all comes down to the saying ‘If it ain’t broke don’t fix it’. It does just what it is supposed to do and that is to get the computer started and make sure everything is in place, and then it hands everything over to the computer’s Operating System.
Determine if the CMOS still utilizes RAM, requiring a battery on the motherboard, or has evolved into using EEPROM?
There are still CMOS that use a battery on the motherboard but EEPROM is more popular today. EEPROM is considered an advance feature and, as a result, has not been accepted by the majority of the market (CMOS, 2013).
