Final answer:
RAM is a type of computer memory that can be read from and written to. It is not found in the ROM chip on the motherboard, and it is not specifically storage for boot-up instructions. While RAM can be considered short-term memory, it is not the only type of short-term memory.
Step-by-step explanation:
Random Access Memory (RAM) is a type of computer memory that can be both read from and written to. It is not found in the ROM chip on the motherboard, as stated in option 2. Option 3 is incorrect as RAM is not specifically storage for instructions needed to boot up the computer. Option 4 is partially correct, as RAM can be considered short-term memory, but it is not the only type of short-term memory.
