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. How wide is Random-access memory?High data transfer rates, crucial for modern high-performance computing
2. What is the memory type?Volatile semiconductor memory, primarily DRAM and SRAM
3. What is the access latency?Extremely low, enabling rapid data retrieval and manipulation by the CPU
4. What is RAM and why is it called "random access"?RAM is a fast, temporary memory that lets the computer's brain (CPU) read and write data quickly. "Random access" means the computer can jump straight to any spot in RAM without having to go through everything first.
5. Why do computers need RAM instead of just using a hard drive or SSD?Hard drives and SSDs are slower, so the computer would wait a long time for data. RAM is much faster, letting the computer keep the parts it is using right now close at hand for instant access.

Latency: The time delay between initiating a request and receiving a response.
Bandwidth: The maximum rate at which data can be transferred over a connection.
Swapping/Paging: Operating system process of moving data between RAM and slower storage to manage memory.
Non-Volatile Memory: Memory that retains data even when power is removed, such as SSDs and HDDs.
