You can use a storage device to store computer information. Storage devices come in many forms. Some examples of these are Floppy Disk, CD-ROM / DVD-ROM, hard disk drive, solid state drive, and USB pen drive. Storage devices can be divided into two types, internal storage devices and external storage devices. Some of the common external storage devices are listed below:

• Floppy Disk
• CD-ROM / DVD Rom
• Hard disk drive
• Solid State disk
• USB Pen drive

FLOPPY DISK:

A floppy disk is a removable storage medium that was widely used in the past for storing and transferring files, documents, and software between computers. It was one of the earliest forms of portable data storage and was popular from the 1970s to the late 1990s.  The disks were inserted into floppy disk drives on computers, which allowed users to read, write, and copy data to and from the disk. Although floppy disks are no longer widely used, they hold historical significance as one of the first portable storage mediums and played a crucial role in the early days of personal computing. Today, they are mostly considered a relic of the past, and modern data storage solutions offer much greater capacity, reliability, and convenience.

CD-ROM/DVD-ROM:

CD (Compact Disc) and DVD (Digital Versatile Disc) are optical storage media used for storing digital data, including audio, video, and computer files. Both CDs and DVDs use a laser to read and write data, but DVDs have a higher storage capacity than CDs. CDs were introduced in the early 1980s and became a popular medium for distributing music albums, software, and data. A standard CD can store up to 700 MB of data. CDs are read-only (CD-ROM), write-once (CD-R), or rewritable (CD-RW), depending on their type. DVDs were introduced in the late 1990s and quickly replaced CDs as the primary medium for storing and distributing movies and large amounts of data. DVDs have a significantly higher storage capacity, with a standard single-layer DVD holding up to 4.7 GB of data. Dual-layer DVDs can store up to 8.5 GB.

Hard Disk Drive:

A hard disk, also known as a hard drive or HDD (Hard Disk Drive), is a primary storage device used in computers to store and retrieve digital data. Hard disks are available in various storage capacities, ranging from a few gigabytes to multiple terabytes, making them suitable for storing vast amounts of data, including operating systems, applications, documents, media files, and more. They are widely used in desktop computers, laptops, servers, and other computing devices.

Solid State Drive:

A solid-state drive (SSD) is a type of data storage device that uses flash memory to store and retrieve data. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, which makes them faster, more reliable, and less prone to mechanical failures. Solid-state drives offer a significant improvement in performance, energy efficiency, and reliability compared to traditional hard disk drives. As technology continues to advance, SSDs are expected to play a crucial role in the future of data storage and computing.

USB Pen Drive:

A pen drive, also known as a USB flash drive or thumb drive, is a small and portable data storage device that uses flash memory to store digital data. It is shaped like a small stick and typically features a USB connector at one end, allowing it to be easily plugged into a computer or other compatible devices. Pen drives have become an indispensable tool for managing digital data, offering a portable, reliable, and efficient solution for storing and transferring files in today’s digital age. One of the key advantages of pen drives is their plug-and-play functionality. They do not require an external power source or additional cables to operate.
