Difference between RAM and HDD

 RAM and HDD both are types of computer memory, RAM is used to store computer programs and data that the CPU needs in real-time. RAM data is volatile and is erased once the computer is switched off. HDD has permanent storage and it is used to store user-specific data and operating systems files.

Definition of RAM

RAM stands for random access memory, it is used to store the program and the data being used by the CPU in real-time. The data on the RAM can be read, written, and erased any number of times. RAM is a hardware element where it to be the data being currently used is stored. It is volatile memory.

Definition of HDD

HDD stands for a hard disk drive, It is called secondary memory. HDD memory is very high. It ranges from 500 GB to 4 TB on the desktop. HDD is used for storing digital information rapidly rotating disk coated with magnetic materials.

Difference between RAM and HDD:

• RAM stands for random access memory, while the HDD stands for a hard disk drive.
• RAM also called primary memory or main memory, while HDD is called secondary memory.
• CPU can access data stored on RAM, while in Data to be copied from ROM to RAM so that CPU can access its data.
• RAM has no moving mechanical part and consists of transistor etc, while in HDD contains moving mechanical parts like arms, pins, etc.
• RAM is costly per unit storage, and HDD is cheap per unit storage.
• Every memory area of RAM is accessible, while a different area of HDD may take a different time to access.
• RAM has a small read/write, and HDD has a higher read/write time.
• RAM doesn't produce any noise, While the HDD produces noise due to mechanical movements.
• RAM memory is generally smaller than the HDD. nowadays its ranges from 1 GB to 8 GB on desktops, and HDD memory is very high. It ranges from 500 GB to 4 TB on the desktop.
• If RAM is low, the computer will become slow, and HDD has not much impact on computer speed.
