What is the Full Form of ROM?
ROM stands for Read-Only Memory. It is a type of storage media that can be read but not written, and it is used in computers, smartphones and other digital devices.
Why do We Use ROM?
ROM is used to store the initial startup instructions for a computer or other digital device, also known as firmware. It can also store programs and data that are essential for the device to operate, such as a computer’s BIOS and a smartphone’s operating system.
Types of ROM
There are several types of ROM, such as mask ROM, programmable ROM (PROM), erasable programmable ROM (EPROM), and electrically erasable programmable ROM (EEPROM). Mask ROM is the most common form of ROM and is used to store data permanently.
Advantages of ROM
ROM has several advantages over other types of memory. It is non-volatile, meaning it does not need power to retain data, and it is also very reliable and durable, making it ideal for storing critical data. ROM also has fast access times and is relatively inexpensive.
Disadvantages of ROM
The main disadvantage of ROM is that it cannot be easily updated or changed. Once data is written to ROM, it cannot be modified, which can be a problem if the data needs to be updated or changed. Additionally, ROM is limited in terms of storage capacity.
