1. What is memory and what does it do?
Memory is a computer component that stores data and instructions. It can be temporary (volatile storage) or permanent (non-volatile storage) and is used to support system operation and data storage.
-
2. Is there a relationship between the capacity and speed of memory?
The capacity and speed of memory are not directly related. The capacity refers to the amount of data that the memory can hold, while the speed determines the speed at which the memory reads and writes data. Generally speaking, faster memory such as RAM has a smaller capacity, while large-capacity storage such as HDD is relatively slow.

3. What is the difference between cache and RAM?
Cache is a high-speed memory between the CPU and the main memory, which is used to temporarily store data and instructions commonly used by the CPU to speed up the system. RAM is the main storage of the system, which is used to store data for applications and operating systems.
-
4. What is double data rate (DDR) memory?
DDR memory is a RAM technology that can transmit data at both the rising and falling edges of the clock signal to increase the data transmission speed. There are multiple generations of DDR, such as DDR3, DDR4, DDR5, etc., each generation has higher speed and capacity and lower power consumption.
