Detailed explanation-1: -Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive, CD, etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory.
Detailed explanation-2: -The two main types of primary storage are ROM, which is non-volatile, and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off.
Detailed explanation-3: -There are two types of memory: RAM (Random Access Memory) which can read and write data, and ROM (Read Only Memory) which mainly stores programs as read-only data.
Detailed explanation-4: -There are two main kinds of semiconductor memory, volatile and non-volatile. Examples of non-volatile memory are flash memory and ROM, PROM, EPROM and EEPROM memory. Examples of volatile memory are dynamic random-access memory (DRAM) used for primary storage, and static random-access memory (SRAM) used for CPU cache.
Detailed explanation-5: -Unlike RAM, Read Only Memory (ROM) delivers both non-volatile and permanent primary storage. ROM retains its contents even if the device loses power.
