This article mainly introduces the characteristics of ROM, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

ROM is characterized by read-only, no write and no loss of information after shutdown. ROM operates in a non-destructive read mode, reading only information that cannot be written. Once the information is written, it is fixed, and even if the power supply is cut off, the information will not be lost, so it is also called fixed memory.

Read-only memory (ROM) works in a non-destructive read mode, reading only information that cannot be written. Once the information is written, it is fixed, and even if the power is cut off, the information will not be lost, so it is also called fixed memory.

ROM stored data is usually loaded into the machine before writing, the machine can only read out during the work process, unlike random access memory can quickly and easily rewrite the storage content. ROM stored data is stable, the stored data will not change after power failure, and the structure is relatively simple, easy to use, so it is often used to store various fixed programs and data.

Read only memory is characterized by only reading and can not write information, usually in the computer motherboard ROM inside the solidification of a basic input/output system, called BIOS (basic input output system). Its main function is to complete the power-on self-test of the system, the initialization of each functional module in the system, the basic input/output driver of the system and the boot operating system.

Thank you for reading this article carefully. I hope that the article "What are the characteristics of ROM" shared by Xiaobian will be helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
