Short note on internal and external memory of computers
Answers
Answer:
Internal memory typically refers to main memory (RAM), but may also refer to ROM and flash memory. In either case, internal memory generally refers to chips rather than disks or tapes.
In a computer, all of the storage spaces that are accessible by a processor without the use of the computer input-output Internal memory usually includes several types of storage, such as main storage, cache memory, and special registers, all of which can be directly accessed by the processor.
Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner.
external memory
External memory typically refers to storage in an external hard drive or on the Internet. The main “memory” in the computer is the computer work-space, not its storage facility.
External memory which is sometimes called backing store or secondary memory, allows the permanent storage of large quantities of data. Some method of magnetic recording on magnetic disks or tapes is most commonly used
The capacity of external memory is high, usually measured in hundreds of megabytes or even in gigabytes
The most common form of external memory is a hard disc which is permanently installed in the computer and will typically have a capacity of hundreds of megabytes
Answer:
Internal memory, also called "main or primary memory" refers to memory that stores small amounts of data that can be accessed quickly while the computer is running
