Defination Of RAM Memory (Random Access Memory)
RAM Memory which stands for random access memory, is a sort of Computer Memory that is used for the purpose of temporarily storing data that the computer is now using or processing. RAM And ROM Memory, Random-access memory (RAM), being a type of volatile memory, loses its stored information upon power switching off. The computer commonly uses RAM And ROM Memory, (RAM) to store its operating system, application programs, and current data.
Defination Of ROM Memory (Read Only Memory)
ROM Memory, often known as ROM, is a sort of computer memory that is used for the purpose of storing data in a permanent manner that does not need any modifications. A ROM is a kind of memory that is non-volatile, which means that the information that is stored in it is preserved even if electrical power is switched off. ROM is primarily used for the purpose of storing the basic input/output system (BIOS) of a computer. This RAM And ROM Memory system is responsible for storing the instructions necessary to start the computer, in addition to firmware related to other hardware components.
Difference Between RAM And ROM Memory
| Difference | Random Access Memory (RAM) | Read Only Memory (ROM) |
| Read/Write | It is possible to do read and write operations. | It is only possible to perform read operations. |
| Use | Used to temporarily store the data that the central processing unit (CPU) needs to process at the moment. | The majority of the time, it stores firmware or microcode, which The process starts with initializing and controlling the computer’s hardware components. |
| Data-Retention | RAM is a kind of memory that is not permanent and may hold the Information is available as long as there is an electricity supply. | Real-time memory (ROM) is a kind of memory that does not lose its contents. Data, even if the power is switched off, is still available. |
| Speed | High-speed memory is what it is. | The RAM is far faster than this. |
| CPU Interaction | The CPU can access data immediately from RAM. | Data that is stored in the ROM is difficult for the CPU to access. |
| Used as/in | The primary memory and the CPU Cache. | Firmware, Micro-controllers. |
| Size and Capacity | Large size with a larger capacity in terms of read-only memory (ROM). | Smaller in size and having a lower capacity in terms of RAM. |
| Chip Size | RAM chips are only capable of storing a few gigabytes (GB) of data at a time. | It is possible for a ROM chip to hold many megabytes (MB) of data. |
| Cost | The cost of RAM is higher than that of ROM. | The cost of ROM is lower than that of RAM. |
| Function | Utilized for the purpose of providing a temporary storage location for data that is presently being processed by the central processing unit. | It is used for the purpose of storing firmware, BIOS, and other data that must be preserved. |
| Accessibility | Obtaining the saved data is not difficult. | Retrieving the stored data is not as straightforward as it is in the RAM under discussion. |
