Disadvantages of ROM
- It is a read-only memory, so it cannot be modified.
- It is slower as compared to RAM.
Read Only Memory (ROM)
In a computer system, memory is a very essential part of the computer system and is used to store information for instant or permanent use. Based on computer memory working features, memory is divided into two types i.e. Volatile and Non-Volatile Memory. Before understanding ROM, we will first understand what exactly volatile and non-volatile memory is. Non-volatile memory is a type of computer memory that is used to retain stored information during power is removed. It is less expensive than volatile memory. It has a large storage capacity. ROM (read-only memory), and flash memory are examples of non-volatile memory. Whereas volatile memory is a temporary memory. In this memory, the data is stored till the system is capable of, but once the power of the system is turned off the data within the volatile memory is deleted automatically. RAM is an example of volatile memory.
