INTRODUCTION OF RAM(RANDOM ACCESS MEMORY)

Random Access Memory (RAM) is a hardware device that allows information to be stored and retrieved on a computer. RAM is usually associated with DRAM, which is a type of memory module. Because information is accessed randomly instead of sequentially like it is on a CD or hard drive, the computer can access the data much faster. However, unlike ROM or the hard drive, RAM is a volatile memory and requires power to keep the data accessible. If the computer is turned off, all data contained in RAM is lost.

As the computer boots, parts of the operating system and drivers are loaded into memory, which allows the CPU to process the instructions faster and speeds up the boot process. After the operating system has loaded, each program you open, such as the browser you're using to view this page, is loaded into memory while it is running. If too many programs are open, the computer will swap the data in the memory between the RAM and the hard disk drive.

A computer's speed and performance is largely attributed to the amount of memory in the computer. If a computer does not have enough memory to run the operating system and software programs being used, it will result in a slower performance. More memory in a computer allows it to efficiently run the operating system and any software programs, reducing or eliminating the need for files and data to be swapped in and out of memory every second.
