One component of the internal memory of a computer is Random Access Memory (RAM). Which of the following statements are correct about characteristics of RAM?
A. RAM can be read from the written to
B. RAM is volatile memory
C. RAM is temporary storage
D. Modern PCs typically have from 2TB upto 32 TB of RAM
Choose the correct answer from the options given below:

Correct option is B

The correct answer is (b) A, B, and C only.
 A. RAM can be read from and written to - This statement is correct. RAM is a type of memory that can be both read from and written to by the CPU. This means that the CPU can access and modify the data stored in RAM.
 B. RAM is volatile memory - This statement is correct. RAM is a type of memory that requires power to maintain the stored information. When the power is turned off, the data stored in RAM is lost. This is why RAM is often referred to as temporary storage.
 C. RAM is temporary storage - This statement is correct. As mentioned above, RAM is volatile memory and the data stored in it is lost when the power is turned off. Therefore, RAM is only used for temporary storage of data that needs to be accessed quickly.
Information booster:
 D. Modern PCs typically have from 2TB upto 32 TB of RAM - This statement is incorrect. While the amount of RAM in PCs has been increasing in recent years, modern PCs typically have between 4GB and 16GB of RAM. 2TB of RAM would be extremely expensive and unnecessary for most users, and 32TB of RAM would be impractical to install in most computers.
Therefore, the only statements that are correct about the characteristics of RAM are A, B, and C.
