DIFFERENCE BETWEEN RAM AND ROM
The differences between RAM and ROM are as follows:
RAM ROM
It stands for Random Access Memory. It stands for Read-only Memory.
It is a volatile memory. It is a non-volatile memory.
It helps the computer while it is working. It helps the computer to start.
It is a high-speed memory. It is slower as compared to RAM.
Example: Playing games, writing in a Example: Booting up a computer.
document, watching videos, etc.
RAPID RECALL Tick ( ) if you know this.
1. Computers store data using only two numbers, 0 and 1.
2. Primary memory is also known as Internal memory.
SECONDARY MEMORY
Secondary memory is permanent in nature. It is used to save work for a longer
period of time. The CPU cannot access data directly from secondary storage; the
data must first be copied to the primary memory (RAM), which makes it slower.
However, secondary memory is essential because it is cheaper and has much larger
capacity than primary memory. The devices associated with secondary memory
are called secondary storage devices. Let us discuss the various types of secondary
storage devices.
HARD DISK
A Hard Disk or Hard Disk Drive (HDD) is a common storage device
that uses flat round magnetic disks, called platters, to read and
write data. It is fixed inside the CPU cabinet/box. When you save any
document or download a game, it gets stored on a hard disk. Hard
disks are available in various storage capacities such as 512 GB, 1 TB, 5 TB and more.
