Answer: Option B
When data is entered through an input device like a keyboard, it is temporarily held in memory until it can be processed by the processing unit. Memory, also known as RAM (Random Access Memory), is a volatile type of computer storage that can be accessed randomly and stores data and instructions required by the CPU (Central Processing Unit).
Here are some relevant definitions and formulas related to memory:

• Memory is a hardware component of a computer system that stores data and instructions.
• RAM (Random Access Memory) is a type of memory that can be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes.
• Volatile memory requires a power source to hold data, meaning that data is lost when power is turned off.
• Memory capacity is measured in bytes, kilobytes, megabytes, gigabytes, or terabytes.
• Memory speed is measured in nanoseconds (ns) or megahertz (MHz).

In summary, memory temporarily holds the data received from input devices until it can be processed by the CPU. This is an essential part of the computer system because it enables the computer to perform tasks and store data that can be accessed quickly.
