RAM and ROM

Question: Discuss about the RAM and ROM. Answer: Differences between RAM and ROM RAM ROM Also known as Random Access Memory, and the data stored on it can be accessed randomly from any location and at any time, for fast access and manipulation. Also known as Read Only Memory, and the data stored on it cannot be easily modified or reprogrammed. It is necessary for the computer to startup from the boot and is hardwired. As opined by Hummen et al. (2013), it is volatile, which means the data get erased when the system is turned off. It is non-volatile, which means its data does not get deleted when the system is turned off and is permanent. Read and Write functions are performed for applications to run. Its only use is to read information and the data stored here cannot be modified. It is of two types Dynamic RAM (DRAM) and Static RAM (SRAM). It has three categories PROM, EPROM, and EEPROM. Electricity is needed to preserve information. It does not require electricity to maintain data. RAM According to Patterson and Hennessy (2013), RAM is also known as Read Only Memory and is used to store temporary data onto the computer when the system is turned on, which means electricity is needed to store information. It is volatile in nature. Its access speed is very fast, and the processor uses it for a speed boost. Both read and write operations are supported. It is categorized into two types Dynamic RAM (DRAM) and SRAM (Static Ram). SRAM is fast and expensive and is used for CPUs speed-sensitive cache, while DRAM is slower and less expensive and is used for a large amount of RAM space.
