There are two main types of RAM: static RAM and dynamic RAM. Static RAM retains information without refreshing and can operate at high speeds, while dynamic RAM is used in most personal computers and requires refreshing to retain information, making it less expensive but also less powerful than static RAM. RAM is a type of volatile memory used in cache and registers.
