Storage devices
This lesson includes the following sections:
Categorizing Storage Devices
Magnetic Storage Devices
Optical Storage Devices
Storage devices hold data, even when the computer is turned off.
The physical material that actually holds data is called a storage medium. The surface of a floppy disk is a storage medium.
The hardware that writes data to or reads data from a storage medium is called a storage device. A floppy disk drive is a storage device.
The two primary storage technologies are magnetic and optical.
Diskettes (floppy disks)
Hard disks
High-capacity floppy disks
Disk cartridges
Magnetic tape
Compact Disk Read-Only Memory (CD-ROM) A magnetic disk's medium contains iron particles, which can be polarized—given a magnetic charge—in one of two directions.
Each particle's direction represents a 1 (on) or 0 (off), representing each bit of data that the CPU can recognize.
A disk drive uses read/write heads containing electromagnets to create magnetic charges on the medium.
Digital Video Disk Read-Only Memory
(DVD-ROM)
CD-Recordable (CD-R)
CD-Rewritable (CD-RW)
PhotoCD
This section of the memory is also referred to as backup storage.
The storage capacity of primary storage is not sufficient to store the large volume so secondary storage.
Secondary storage also know as external memory or auxiliary storage not directly accessible by the CPU.
A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Humankind has always tried to find ways to store
information. In today s modern age, people have
become accustomed to technological
terminology, such as CD-ROM, USB Key, and
DVD. Floppy disks and cassette tapes have been
forgetting except for the most nostalgic.
Subsequent generations have simply forgotten
about the technology that helped evolve the
efficient computer storage systems we all use
everyday. As time humanity continues to push
the envelope of innovation to create new
possibilities.

tape in 1928. He
based his invention off
Vlademar Poulsen's
magnetic wire.
6. 1932 Magnetic Drum
G. Taushek, an Austrian
innovator, invented the
magnetic drum in 1932.
He based his invention
off a discovery credited
to Fritz Pfleumer.
7. 1946 Williams Tube
Professor Fredrick C. Williams
and his colleagues developed
the first random access
computer memory at the
University of Manchester
located in the United
Kingdom. He used a series of
electrostatic cathode-ray
tubes for digital storage. A
storage of 1024 bits of
information was successfully
implemented in 1948.
8. 1956 Hard disk
A hard disk
implements rotating
platters, which stores
and retrieves bits of
digital information
from a flat magnetic
surface.
9. 1963 Music tape
Philips introduced the compact
audio cassette in 1963. Philips
originally intended to use the
audio cassette for dictation
machines; however, it became
a popular method for
distributing prerecorded music.
In 1979, Sony's Walkman
helped transformed the use of
the audio cassette tape, which
became widely used and
popular.
10. 1971 8" Floppy
IBM started its development of
an inexpensive system geared
towards loading microcode into
the System/370 mainframes. As
a result, the 8-inch floppy
emerged. A floppy disk, a
portable storage device made of
magnetic film encased in
plastic, made it easier and faster
to store data.
11. 1980 CD
During the 1960s, James T. Russel
thought of using light to record and
replay music. As a result, he invented the
optical digital television recording and
playback television in 1970; however,
nobody took to his invention. In 1975,
Philips representatives visited Russel at
his lab. They paid Russel millions for him
to develop the compact disc (CD). In
1980, Russel completed the project and
presented it to Sony.
12. 1981 3.5" Floppy
The 3.5-inch floppy disk
had significant advantages
over its predecessors. It
had a rigid metal cover
that made it harder to
damage the magnetic film
inside.
13. 1990 MOD
The Magneto-Optical disc
emerged onto the information
technology field in 1990. This
optical disc format used a
combination of optical and
magnetic technologies to
store and retrieve digital data.
A special magneto-optical
drive is necessary to retrieve
the data stored on these 3.5
to 5.25-inch discs.
14. 1995 DVD
DVD became the next
generation of digital disc
storage. DVD, a bigger and
faster alternative to the
compact disc, serves to store
multimedia data.
15. CD-RW
The Compact Disc Rewritable disc, a
rewritable version of the CD-ROM,
allows users to record digital data
over previous data.
16. 1997 Multimedia Card
The Multimedia Card (MMC)
uses a flash memory card
standard to house digital
data. It was introduced by
Siemen's and SanDisk in
1997.

A USB Flash Drive uses a
NAND-type flash memory to
store digital data. A USB Flash
Drive plugs into the USP
interface on standard
computers.
18. SD Card
The Secure Digital (SD) flash
memory format incorporates
DRM encryption features
that allow for faster file
transfers. Standard SD cards
measure 32 millimeters by
32 millimeters by 2.1
millimeters. A typical SD
card stores digital media for
a portable device.
19. 2003 Blu Ray
Blu-Ray is the next generation
of optical disc format used to
store high definition video
(HD) and high density storage.
Blu-Ray received its name for
the blue laser that allows it to
store more data than a
standard DVD. Its competitor
is HD-DVD.
20. Cloud Backup Solutions
Zetta’s cloud enables
businesses to protect data
using backup, recover from a
disaster, and archive unused
files using only a lightweight
sofware client and Zetta’s bi-
coastal datacenters. As
