Floppy Disk Presentation
The floppy disk was invented in 1967 and evolved from 8-inch to 5.25-inch disks, which were used starting in 1981 and could hold 360KB. Floppy disk drives are no longer being installed in computers but can be used with a USB floppy drive, which costs around $20 and allows access on any computer. Floppy disks have been replaced by more convenient and durable USB sticks.
Floppy disk & drive
A floppy disk is a magnetic storage medium sealed in a rectangular plastic carrier that is read and written by a floppy disk drive. Floppy disks were commonly used to store files and boot systems when hard drives were less common. They came in 5.25 inch and 3.5 inch sizes, with storage capacities ranging from 100KB to 1.44MB. Floppy disks worked by using read/write heads very close to a magnetic disk coated with particles that could hold data bits.
Floppy disk
The floppy disk drive was invented in 1967 by Alan Shugart, using 8-inch disks initially that later evolved into the ubiquitous 5.25-inch disks holding 360KB introduced in 1981. Floppy disks recorded data using magnetic material coated on a thin plastic disk, allowing information to be stored, erased, and rewritten easily and inexpensively. While floppy disks were popular for decades, the technology became obsolete as higher capacity storage options emerged, and floppy disk drives are no longer installed on modern computers, though some users still access the format using inexpensive USB floppy disk drives.

Computer applications 11 floppy
Floppy disks were invented in 1973 and were an early form of data storage for computers. They stored data in sectors and tracks and their storage capacity increased over time, with double-sided extended-density 3 1/2 inch floppy disks storing the most at around 1.2 megabytes. Floppy disks were superseded by higher capacity storage devices but were pivotal in the early development of personal computing.
Assignment 2.1
Hard disks store and provide quick access to large amounts of data. They were originally large 20-inch disks holding a few megabytes, now use magnetic recording and are much smaller. Floppy disks were small removable devices that added data until CDs replaced them; they were invented in 1967 and held up to 1.44 megabytes. Main memory (RAM) is fast temporary storage used by the CPU to access data more quickly than from the hard drive. Processors are the computing elements and have advanced from 4-bit addition/subtraction to 32-bit and soon 64-bit capabilities. Monitors display output and can be LCD or CRT, with laptops using slimmer LCDs and desktops usually using CRTs.

Data storage formats also included CD-Rs, tape drives, XD cards, mini DVDs, DVD-RWs, CD-RWs, multimedia cards, transflash cards, memory pens, smart media cards, and compact flash cards.
Hard disk drive
Hard disk drives (HDDs) are data storage devices that store and retrieve digital information using rapidly rotating disks coated with magnetic material. HDDs have greatly increased in capacity over time, from megabytes to terabytes, while decreasing dramatically in size and cost. Key components include disks, read/write heads, and an actuator arm that moves the heads over the disks. Error correction allows high recording densities without data loss. Future developments may allow even higher capacities through new magnetic recording technologies.

Hard disk & Optical disk (college group project)
- Hard disk drives (HDDs) are devices used for digital data storage. They consist of rapidly rotating discs coated with magnetic material. Magnetic heads write data to and read data from the disc surfaces.
- HDDs were first introduced in 1956 and have since decreased dramatically in size and cost, becoming standard in personal computers by the late 1980s. Capacities have also increased greatly, with modern HDDs capable of storing terabytes of data.
- Optical discs like CDs and DVDs store data in the form of pits and lands on a reflective surface. They were invented in the late 1950s and early 1960s and are now commonly used to store music, video, and computer programs and data.
Removable media up
Removable media refers to storage media that can be removed from a computer without shutting it down. Common types of removable media include optical discs (CDs, DVDs, Blu-rays), memory cards, floppy disks, and USB flash drives. These allow data to be easily transferred between computers or other devices.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Computer Storage Options Changed 3
- 1. Computer Storage Options By Andrew Carey
- 3. The first hard drive was introduced into a computer in 1956 in the 305 computer. It had fifty 2 foot diameter disks with 100 recording surfaces. Each surface had 100 tracks. The disks spun at 1200 RPM. The maximum capacity for this hard drive was only 5 MB (megabytes). The cost per MB was calculated at $10,000 at that time. Hard Drives IBM RAMAC 305 One of the 2 foot disks
- 4. Hard Drives Today Hard drives have gotten smaller in size and larger in capacity, and much cheaper. The smallest hard drive is 0.85 inches and holds 8 GB (8192MB), and weighs 2 grams. The largest capacity commercial hard drive is 2 TB and is 3.5 inches. The 2 TB hard drive is 419,430 times larger than the 5 MB hard drive of the IBM 305. The 2 TB hard drive retails for $299. Toshiba 8 GB micro hard drive Western Digital 2 TB hard drive
- 5. Floppy Disks Floppy Disks were first introduced in 1969 by as an 8 inch disk with a capacity of 80 kilobytes. In 1976 Shugart Associates came out with the 5¼ inch disk with a capacity of 110 kilobytes. In 1982 Sony came out with the most commonly known floppy disk, the 3½ inch, able to hold 264 kilobytes. Most floppy disks today can still only hold about 2MB of data. While most computers still have a floppy drive for these disks, they are rarely used. There are much more practical uses for them as seen below. Floppy disk ball 8”, 5 ¼”, and 3½” floppy disks 1998 Honda Civic floppy disk car
- 6. CD-R The first CD-R was made in 1988 by Taiyo Yuden. CD-R’s are capable of holding between 184MB and 870MB. The most common CD-R is the 80 (minutes of music)/700MB (data) disk. A standard 100 pack of CD-R’s costs about $25-$30. Most non-gaming computer software sold in the United States is distributed via CD. UltraLife™ Gold Archival Grade CD-R 80MIN 700MB 52X
- 7. DVD-R The first DVD-R was developed in 1997 by Pioneer. DVD-R’s are capable of holding between 4.7GB and 9.4GB. The most common DVD-R is the 120 (minutes of digital video)/4.7GB (data) disk. A standard 100 pack of DVD-R’s costs about $30-$40. Most gaming computer software sold in the United States is distributed via DVD because of its large storage capacity. DVD’s are well on the way of making CD’s obsolete, as a means of optical data storage.
