Memory is a type of computer data storage accessed by the central processing unit (CPU) and random-access memory (RAM). It is a volatile type of data storage, meaning it must be constantly rewritten to a new location to retain its contents.

Introduction
In this article, we will discuss the differences between ROM and RAM and the different types of memory available for your computer. We will also define each type of memory.
ROM:
ROM is a type of memory that permanently stores data on your computer or other devices. The data stored in ROM can not be modified or deleted. ROM is typically used to store your computer’s BIOS (Basic Input Output System), which is responsible for starting up your device.
RAM:
RAM is a type of memory that temporarily stores data on your computer. The data stored in RAM can be accessed quickly by the processor and deleted when no longer needed. RAM is typically used to store programs and files that the processor is currently using.
Both and RAM are essential for your device to function properly. Without ROM, your device would not be able to start up. Without RAM, your device would not be able to store any programs or files that are the processor is currently using.
The main difference between ROM and RAM is that ROM is non-volatile, and RAM is volatile. This means that ROM does not require power to maintain the information stored in it, while RAM does require energy.
Advantages of Permanently Installed Memory
One of the advantages of ROM is that it can hold data even when there is no power supply to the computer. This makes it ideal for storing firmware, which is a type of software that is required to start up a computer or other device. Firmware usually consists of low-level code that is responsible for basic tasks such as initializing hardware and booting the operating system.
Another advantage of ROM is that it often stores essential data that should not be lost if power is lost, such as the BIOS settings on a motherboard. This data can be critical for booting up a computer or recovering from an error.
Disadvantages of Permanently Installed Memory
ROM is a permanent or semi-permanent memory that a computer device uses as system storage. It typically refers to a system’s firmware or hardwired logical components that retains data even when there is no power supply. ROM is used to enable system startup and basic input/output operations.
