Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary function?To store data and program instructions for immediate CPU access
2. What is the key principle?Data is stored in memory cells, typically representing binary digits (bits)
3. What is computer memory and why is it important?Computer memory, also called RAM, is the fast storage that holds data and program instructions so the CPU can use them quickly. It helps the computer run smoothly.
4. How does computer memory remember information?Memory cells use tiny electronic parts like MOS transistors and capacitors to store a single 0 or 1. Many cells are arranged in arrays so the computer can find the right data quickly.

DRAM (Dynamic Random-Access Memory): The most common type of volatile main memory, using capacitors to store data.
SRAM (Static Random-Access Memory): Faster, more expensive volatile memory, often used for CPU caches.
Virtual Memory: A memory management technique that uses disk space to simulate additional RAM.
Integrated Circuit (IC): A small electronic circuit containing many components on a single chip.
