RAM & ROM

RAM & ROM

1. RAM stands for Random Access Memory

   • RAM is a type of data that can be accessed randomly
   • That means that any byte of memory can be accessed without touching the previous byte
   • RAM is the most common type if memory found in computers and devices such as Printers.
   • RAM is a computer storage location that allows data to be accessed quickly from anywhere on the DRAM (Dynamic Random Access Memory)
   • The data is accessed Randomly, which allows it to be faster than that of a hard drive.
   • Unlike ROM, RAM is a volatile memory and required power to be able to access the data. Without power, memory is lost.

2. ROM stands for Read-only Memory

   • ROM is a type of built-in memory that can only be read
   • It can be only be modified with great difficulty, or not at all.
   • Unlike RAM, ROM keeps its data even without power. It is non-volatile.
   • An example of ROM is the cartridge used with video game devices; which allows it to run multiple games at the same time.
   • The oldest example of a ROM type storage media is dated 1932.
   • Today, ROM-type is continued to be improved for better performance and bigger storage-capacity.
