The most accurate answer is PROM (Programmable read-only memory) a.k.a. OTP ROM (One-time programmable ROM). You can fill it with data once, but after that you cannot modify it. Example: PROM chips and CD-R.

EPROM - Erasable Programmable Read Only Memory.
RAM, or random access memory.
READ-ONLY memory is protected against modification by a simple user Write Command. It is generally used to hold low level code such as the Instruction Set for the Computer Hardware itself. The typical application user can NOT address this memory area, but on their behalf, the Operating System can read the memory contents, but NOT modify it. Memory Chips of this type are typically FLASHED to make updates to their contents.
The motherboard has a lithium battery on it that is juuuust strong enough to keep the memory from losing its data.
wich memory type does not loose its data contents when power is removed from the unit
The contents of the Random Access Memory (RAM) are lost on switch off, unless the contents is first saved to the hard drive, or an external drive. RAM is considered to be a volatile memory.
RAM stands for 'Random Access Memory', its your computer's 'working memory' much like how your short-term memory is used to remember the current tasks you are doing. When the computer is powered off, the RAM is automatically cleared, and whenever you do something on the computer (like launch a program) that program is temporarily stored in the RAM until it is closed. The contents of your RAM will change all the time as you do different things with your programs (like open a website in your web browser). So yes, it's possible to change the contents of your RAM, because these contents are always changing.
RAM stands for Random Access Memory. It is a type of computer memory that is used to store data and machine code that is currently being used or processed by the CPU. RAM is volatile memory, meaning it loses its contents when the computer is powered off.
What is a type of data manipulation that doesn't affect the contents of a database?
Read Only Memory (ROM) is a type of non-volatile memory where data is permanently written during manufacturing and cannot be easily altered or deleted. ROM is commonly used to store firmware and essential software instructions that are needed to boot up a device or system.
