Primary Storage

1. Ram

RAM (Random Access Memory) is a computer's fast, temporary storage for data the CPU is actively using, allowing it to quickly access operating systems, applications, and files for smooth multitasking, but it's volatile, meaning data disappears when the power is off

2. Rom

ROM (Read-Only Memory) is a type of non-volatile computer memory that stores data permanently, even when the power is turned off. It is primarily used to hold critical, unchanging instructions known as firmware, such as the software that enables a device to boot up

Secondery Storage

1. Floppy Disk

A floppy disk (or diskette) is a removable magnetic storage medium in a square plastic casing, containing a thin, flexible disk for storing digital data, read/written by a floppy disk drive (FDD). Popular in the late 20th century

2. Hard Disk Drive

A hard drive (HDD) is a primary computer component that magnetically stores and retrieves digital data, like your OS, apps, photos, and documents, using spinning platters and read/write heads, providing long-term, non-volatile storage that keeps information even when the power is off

3. Magnatic Tape

Magnetic tape is a storage medium using a thin, plastic strip with a magnetic coating (like iron oxide) to record digital data in sequential order, acting as a low-cost, high-capacity solution for long-term storage and backups

4. SD Card (Secure Digital Card)

An SD card (Secure Digital card) is a small, portable flash memory card used to store digital data like photos, videos, music, and apps in various electronic devices, including cameras, smartphones, and tablets, functioning as expandable storage with different sizes (Standard, Mini, Micro) and capacities (SD, SDHC, SDXC, SDUC)

5. CD (Compact Disk or Optical Disk)

A CD (Compact Disc) is a digital optical disc for storing data, originally for music but later for software and files, read by lasers, while "CD" can also mean Certificate of Deposit in finance or Cadmium in chemistry, or refer to other terms like Conduct Disorder in medicine, depending on context.

6. DVD (Digital Video Disk)

DVD (digital video disc or digital versatile disc) is a digital optical disc data storage format. It was invented and developed in 1995 and first released on November 1, 1996, in Japan

7. Pen Drive

A pen drive, also known as a USB flash drive, is a small, portable data storage device that uses flash memory and connects to computers via a USB port for easy file storage, backup, and transfer between devices, thanks to its compact size and plug-and-play functionality.
