One can read and over-write data in RAM.It allow stored data to be accessed in any order with a worst case performance of constant time.It is volatile types of memory,where its stored information is lost if the power is removed.
ROM is Read Only Memory. It holds the codes put there by the manufacture, and is used to start the loading of the Operating System.

Volatile memory refers to RAM that needs to be constantly refreshed to be retained. Static memory is permanent storage that is retained even after the computer is turned off.
There are none as RAM allows random write access while ROM only allows read access (the very reason why it's called ROM because it stands for Read-Only Memory).

A ram is called a ram in English, if you mean a male sheep or goat.
Yes you can do both. RAM stands for random access memory, that that means you can read it or write to it at random. That is different from ROM in which it is only made to be read, but not written to.To be technical, the user doesn't exactly write to RAM, but the CPU and/or the DMA controller does. In assembly code, a programmer asks the CPU to move data from memory to the CPU, or from the CPU to memory.
Random Access Memory is also known as the Main Memory or the Internal Memory.
