Q.1} Write in detail about various drives in Computer.
I) Floppy Drive
II) CD & DVD Drive
Drives are essentially physical storage devices that hold your operating system,
applications, documents, photos, videos, and other files.
Drives can be located inside the computer (internal) or connected externally through ports like USB.
There are different types of storage drives, each with unique features and purposes
like HDD , SDD , FDD, ODD etc.
• Floppy Disk Drive (FDD)
A floppy disk is a type of portable storage device that uses a thin and flexible
magnetic disk to store and retrieve digital information. Floppy disks were widely
used in the past as a popular way to store data on personal computers. They
were introduced in the 1970s and remained a popular storage medium for
several decades until they were gradually replaced by other forms of storage
media.
• Optical Disc Drive (ODD)
Optical discs are a common method of storing huge amounts of data due to their
large storage capacity and durability. Optical discs read and write data using
laser beam. The optical storage technology has been widely employed to large
quantity data like storing music, movies, games, and computer software.
,Types of Optical Storage
Some of the common types of Optical Storage are as follows −
i) CD (Compact Disc)
The Optical Storage CDs were introduced in the early 1980s. In optical
storage technology; CDs were introduced first. They can hold up to 700
megabytes of data and are commonly used for music, software, and data
storage. A CD drive is used to read data from and sometimes write data
to compact discs (CDs). It works by using a laser beam to scan the disc's
surface and interpret the data stored as tiny pits and lands.
ii) DVD (Digital Versatile Disc)
DVDs are extended version of CDs. A DVD drive is used to read and, in
some cases, write data to and from DVDs. It utilizes a laser to read or
write information encoded on the disc's surface. DVD drives are primarily
used for playing movies, installing software, backing up data, and creating
your own DVDs.
iii) Blu-ray Disc
A Blu-ray drive is an optical disc drive that reads and writes Blu-ray discs,
a high-capacity optical disc format. It uses a blue-violet laser to store and
retrieve data, allowing for greater storage capacity and higher quality
video and audio than DVD drives. Blu-ray drives are typically found in
, high-end computers, gaming consoles, and standalone Blu-ray players.
Blu-ray is an advance optical discs storage method. A Blu-ray, may hold
more data than DVDs. Standard discs can carry 25 GB (single-layer) or
50 GB (dual-layer), with larger capacities for specialised variants. Blu-ray
discs are used for both HD video and data storage.
The primary differences between CD, DVD, and Blu-ray discs lie in their
storage capacity, the laser they use to read data, and the quality of the video
and audio they support CD's are an audio-only format. DVD's are video, that
supports 480p, and audio on par with streaming services. Blu-rays hold 8x
the quality over DVD. 1080p, and lossless audio
