MEMORY

1. I know the difference between RAM, ROM and flash memory

   • RAM is memory and vice versa. ROM: Stands for read-only memory. ... Flash memory: A special type of memory that works like both RAM and ROM. You can write information to flash memory, like you can with RAM, but that information isn't erased when the power is off, like it is with ROM.

2. I understand the keywords “volatile” and “non-volatile”

   • Volatile keyword is used to modify the value of a variable by different threads. It is also used to make classes thread safe. It means that multiple threads can use a method and instance of the classes at the same time without any problem. The volatile keyword can be used either with primitive type or objects.

3. I understand the keywords “volatile” and “non-volatile”

   • In the broadest sense, there are three types of memory: sensory memory, short-term memory, and long-term memory.
