Key Points

• SSD (Solid-State Drive):
  • An SSD is a storage device that uses NAND flash memory to store data.
  • It is non-volatile, meaning it retains data even when powered off. SSDs are faster and more durable compared to traditional hard drives (HDD) because they do not have moving parts.
  • The use of Flash memory makes SSDs efficient at performing read and write operations quickly.
• RAM (Random Access Memory):
  • RAM is a type of volatile memory, meaning it only retains data while the device is powered on.
  • Once the power is turned off, the data is lost.
  • RAM allows for fast access to data, which is crucial for active processes and tasks running on the system.
  • The primary role of RAM is to serve as temporary storage for the operating system, applications, and data currently in use.
• HDD (Hard Disk Drive):
  • An HDD is a traditional storage device that uses spinning magnetic platters to read and write data.
  • These platters are coated with magnetic material, and data is stored magnetically.
  • HDDs are slower compared to SSDs because the platters have to spin, and the read/write heads need to move to access data, but they offer much larger storage capacities at a lower price.
• ROM (Read-Only Memory):
  • ROM is a type of non-volatile memory used to store firmware, which is software that is permanently programmed into the hardware.
  • The data stored in ROM is permanent and cannot be easily modified or erased.
  • ROM stores essential instructions for booting up the system and performing basic functions.
  • Since it is non-volatile, it retains the data even when the power is off.
