Internal memory is the computer memory used for storing programs and data that are currently being processed by the CPU. It is also known as primary memory or main memory. Internal memory is directly accessed by the CPU and plays a crucial role in the overall performance of the computer system.

Key Points:
- Internal memory is an essential component of a computer system as it provides the necessary storage space for the CPU to execute instructions and process data.
- It is volatile memory, which means that the stored information is lost when the power supply to the computer is turned off.
- Internal memory is made up of integrated circuits, which are capable of storing and retrieving data at a very high speed.
- It is divided into two types: RAM (Random Access Memory) and ROM (Read-Only Memory).
- RAM is used for storing data and instructions that are currently being executed by the CPU. It allows for fast read and write operations, making it ideal for temporary storage.
- ROM, on the other hand, is used for storing permanent data and instructions that are essential for the computer to function. It retains its contents even when the power is turned off.
- The size of internal memory varies depending on the computer system. It can range from a few gigabytes to several terabytes in modern computers.
- The CPU constantly accesses the internal memory to fetch instructions and data, perform calculations, and store the results. The speed and capacity of the internal memory directly impact the overall performance of the computer system.
- Internal memory works in conjunction with other components of the computer, such as the CPU, cache memory, and secondary storage devices, to ensure efficient processing and storage of data.
- In summary, internal memory is a critical component of a computer system that provides fast and temporary storage for programs and data currently being processed by the CPU. It enables the efficient execution of instructions and plays a crucial role in the overall performance of the system.
