188.8.131.52 explain the differences between RAM and ROM memory
RAM vs ROM
Data and programs need to be stored in a computer system. The technology used to do this is called memory. Memory can be divided into two types: main memory and secondary storage. Main memory is any memory that is directly accessed by the CPU, for example, ROM and RAM.
Definitions and features
ROM (Read Only Memory) provides the computer with instructions that do not change - such as boot setup.
RAM (Random Access Memory) is the working space in which the computer stores data in current use.
RAM and ROM both are the internal memory (main memory) of the computer. RAM is a temporary memory while ROM is a permanent memory of the computer. There are many differences between RAM and ROM, but the basic difference is that RAM is a read-write memory and the ROM is a read only memory.
Volatile memory is computer memory that requires a power supply in order to maintain stored data. In other words, volatile memory will store information as long as power is being supplied to it. However, the moment that the power is turned off, the information is lost. Volatite memory is often referred to as 'temporary memory'.
