What is RAM?
Random Access Memory is abbreviated as RAM. RAM is a temporary storage unit that is cleaned up when the computer is turned off. RAM allocates its memory to the software and applications running on a computer. It is used to store and retrieve data immediately since it takes less time to load than a permanent storage device.
For example, suppose you open Google Chrome on your computer. In that case, the computer loads this program in RAM, and thus you start browsing the internet. RAM also allows the computer to load previously stored information in just a matter of seconds. RAM is crucial in a computer system because, without it, programs and applications are unable to load.
What is ROM?
Read Only Memory is abbreviated as ROM. ROM refers to the non-volatile memory storage in the computer system that stores data unless it is removed from you. The specialty of ROM is that it cannot be erased, meaning that when the computer is turned off, the data remains there. Usually, ROM contains the programmed instructions required for a computer to boot.
This memory storage is helpful for storing data for extended periods of time. Compared to RAM, ROM takes a bit longer to load. ROM is necessary for a system because it contains instructions to boot a computer. Hard drives are the most common examples of ROM.
What is Flash Drive?
A flash drive is a commonly used portable storage device that is used to store and carry data. A flash drive can be attached to the device to exchange data. The distinctive characteristic of a flash drive is that it does not have any parts that move. The design is built on the USB mechanism that typically offers data storage from 5 GB to 64 GB and more.
Some USBs are so advanced that they can store up to 2 TB of data. Flash drives are convenient, handy, and portable. Flash drives come with more comprehensive compatibility options and are also durable and reliable for more extended usage. Its size and writability contribute to its utility.
Difference Between RAM and ROM and Flash Drive
- RAM stands for Random Access Memory; ROM stands for Read Only Memory; Flash drive refers to USBs.
- RAM is a temporary storage device; ROM is a permanent storage device; Flash drive is a portable storage device.
- RAM’s data vanishes when power is off; ROM retains data after turning off; Flash drive can keep data for a longer time.
- RAM is necessary to run programs; ROM is essential for booting up; Flash drive is additional memory storage.
- DDR3 and DDR4 are RAM types; SSD and HDD are ROM types; USBs are the standard form of flash drives.
