Memory And Storage

Types Of Memory Storage

Memory :

RAM , ROM

RAM – Random Access Memory its an type of memory it will stores the temporary data while computers are running its fast and flexible juggling all the programs we’re running at any given moment. RAM is volatile , meaning when it loses its stored data when the power is turned off

ROM – Read Only Memory , is a type of memory that retains data even when the power is turned off. Its non-volatile memory and used to store essential information like firmware and BIOS that your computer needs to boot up

Different Types of RAM

SRAM , DRAM

SRAM – Static Random Access Memory is a fast and expensive type of RAM used in high speed applications like CPU caches, where quick access time is crucial

DRAM – Dynamic Random Access Memory is slower and cheaper than SRAM its needs to be constantly retain data , making it more high maintenance

There are many types of DRAMs :

FPM DRAM

EDO RAM

SDRAM

DDR SDRAM

GDDR SDRAM

With each generation bringing faster speeds and increased efficiency many are obsolete and the common types of DRAM

Many obsolete and the common types of DRAM in the market today are DDR variants like DDR4 , DDR5

GDDR is also worth mentioning it is a specialized type of DRAM optimized for faster data transfer rate , which the GPU needs for its massive parallel processing

GDDR6 is the most widely used today

ROM :

Firmware , BIOS

Firmware : Firmware is a type of software stored in ROM that controls how hardware devices communicate with each other

BIOS : BIOS(Basic Input/Output System) is the first software your computer runs when you power it up its responsible for starting your computer , initializing hardware components and handling over to the Operating System

STORAGE :

HDD, SSD , USB Drive , SD Card

HDD – Hard Disk Drive have been around for long time , they store date on spinning magnetic disks and are known for their large storage capacities at a low price

SSD – Sold State Drive use NAND based flash memory , providing faster data access , reduced power consumption and increased durability compared to HDDs, but come at higher price

NVMe – Non Volatile Memory Express is a high performance interface for SSD that connects directly to the CPU via PCIe lanes , this allows for lower latency and significantly faster data transfer rates compared to SATA-Based SSD’s

USB Drive – Universal Serial Bus or Flash Drive also known as USB drives or thumb drives are small plug and play devices you can use with any USB port they’re easy to use and perfect for transferring files between computers

SD Card - Secure Digital(SD) cards are commonly found in cameras and smartphones they’re smaller and postage stamp but can store 1000’s of files. SD cards come in three main physical sizes : SD, microSD , and mini SD
