10 Differences between RAM and ROM in Tabular form

There are two types of memory in a computer: RAM (Random Access memory) and ROM (Read Only memory)
ROM (Read Only Memory) is used for booting up the computer and to run initial diagnostics.  Let us take an example, BIOS (basic input and output system) is stored in ROM. BIOS controls everything when the computer is switched on. It checks for hardware errors and load basic software before the operating system takes the control. Simply it is a permanent memory setting for starting the computer.
RAM ((Random Access Memory) load the operating system and drivers for particular devices, load an application program, create, change and store data and shut down the computer. Programs are loaded in RAM that’s why we need to save the data often otherwise it loses data when power is turned off.
10 Differences between RAM and ROM (RAM vs ROM)

Stands for Random Access Memory
Stands for Read Only Memory
It keeps operating system, application program, data in use
It contains programs used for booting up the computer and to run initial diagnostics.
Data in RAM can be accessed in any order an can be modified (changed or deleted)
ROM is fixed or data cannot be modified (read only memory)
RAM memory holds data temporarily while the program is being used
ROM is a fixed memory system and virtually indestructible
RAM is volatile (It loses data when power is turned off)
ROM is non-volatile (retains data even when power is off)
Higher units of space recommended up to GB (meant for running application programs)
Storage capacity not an issue as it is not used in running application programs
More expensive
RAM is fast
ROM memory is extremely fast compared to ROM
Types of RAM-dynamic RAM & static RAM
Types of ROM: PROM (programmable read-only memory) like CD ROM, EPROM, (Erasable Programmable Read-only Memory) EEPROM.(Electrically Erasable Programmable Read-Only Memory) .
Example of RAM: RAM chips like 2GB, 4GB, 8GB etc of different companies like Corsair, Kingston etc.
Example of ROM: cartridge in video game consoles, computer BIOS.
