What are the advantages and disadvantages of a floppy disk?

The floppy disk was originally developed at IBM for the purpose of loading microcode RAM in their System 370 computers introduced in 1971. As the disk would only be in the drive at most once a day for no more than a couple of minutes then returned to its protective sleeve, there was no concern about wear or exposure to dirt as there was with earlier removable hard discs.

When they were first adapted to inexpensive data storage on microcomputers, while these issues now became important nothing was done originally to address them. The primary concern for years was only increasing the data capacity and keeping the cost low.

The original IBM 8 inch floppy disks only had a capacity of 80KB, the first microcomputer 8 inch floppy disks increased this to 128KB which was then increased by spacing the tracks closer, doubling the density, and by making use of both sides to: 256KB, 512KB, and finally 1MB.

More compact microcomputer 5.25 inch floppy disks were introduced initially had a capacity of 98.5 KB, which was then by a variety of improvements and use of different formatting increased to 110 KB, 360 KB, 720 KB, and finally 1.2 MB.

Both the 8 and 5.25 floppy disks provided no protection to the media when outside the drive unless the user put them back in their sleeves (which often got lost). Also the "case" enclosing the floppy disk was itself flexible and this could allow the media to be damaged if it was flexed too much.

A new microcomputer 3.5 inch floppy disk was introduced that addressed these issues by using a hard case with a shutter to cover the media when the disk was outside the drive. The most common capacity was 1.44 MB.

However the floppy disks are becoming obsolete as Flash based storage devices (e.g. USB, SD, microSD, CompactFlash) have become widely available at low cost and much higher capacity than floppy disks. Flash based storage devices do not have the problems of wear and dirt that have always challenged the Floppy disks (however they do undergo electrical wearout that limits their lifetime).

Why does your flash drive turn into a floppy drive?

1. this question is very vague. 2. physically your question would not be possible.

How the data is organized in disk?

Blocks of addresses are organized in concentric circles each divided into "sectors" which occupy a portion of the circle. The address of a certain bit of information is the block within a sector.

Floppy drive and CD drive are input or output devices?

Floppy and CD drives are both Output and Input devices based on the context of their usage. For instance, you know that both the drives can read and write their respective media, i.e. input and output. But consider the case where you insert a pre-recorded CD or write-protected floppy into the drive, here the drive falls-back to being an input device. Classifying computer peripherals into I/O devices only is not very efficient now-a-days due to the Hybrid nature of these peripherals. So instead, classifying CD and Floppy drives as Storage Access Devices is more appropriate. The term access here has significance, since the drives itself do not store any data as opposed to common parlance, instead they simply access the Compact Disk and the Floppy Disk for the data.

Why you keep diskette away from magnetic sources?

why should you keep diskettes away from magnetic sources

What are similarities of a floppy disk and a hard disk?

In their basic form, floppy discs are common hard disks are the same technology. They both use magnetism to store and read data. They both use a spinning platter read by a horizontally moving read head.

The key differences are that hard disks have the data and reader in the same package, this is why hard discs have evolved in storage capacity while floppy disks remained the same. It was necessary for the written layer of a floppy disk to have the same data density and dimensions as they had to be compatible with floppy disk drives. However with hard discs the drives and read heads could evolve along side the data layer.

Hard discs now have metal platers, and store data at a much higher density. The speed of the mechanisms are much much faster. New technologies such as perpendicular storage can be added and have no impact on compatibility.

When disk defragmenter is completed why does it use or takes storage space on that disk?

Defragmentation is the process of rewriting non-contiguous parts of a file to contiguous sectors on a disk for the purpose of increasing data access and retrieval speeds. Because FAT and NTFS disks can deteriorate and become badly fragmented over time, defragmentation is vital for optimal system performance.

What are the advantages of long flash over arrester modulator?

  • LFA-Ls help avoid both conductor burnouts and overhead power lines outages caused by lightning induced overvoltages.
  • Eliminate the consequences of lightning flashovers without damaging lines and substations equipment, as opposed to arcing horns, which transform single-phase shorting into two-phase one, thus creating a powerful electrodynamic blow on the equipment.
  • Extend the working life of high voltage circuit breakers.
  • Protect electric networks against arc overvoltages.
  • Cannot be destroyed by lightning currents and power follow currents as metal oxide arresters, gapped silicon carbide arresters or expulsion tubes since currents are flowing outside of LFAs.
  • Are not stressed by operational voltage and do not require maintenance.
  • Do not require reduced grounding resistance of poles on which they are mounted

Can you remove burned data on disks?

Not usually. When CD, DVD, Blu-Ray, etc. Recordables are burnt, the data is usually fixed and cannot be added or removed. However, there are special disks called re-writable disks (RW) and the data can be removed and rewritten several times.

What happens when the floppy cable is installed backwards?

Usually, this will cause the LED to shine constantly, indicating a problem. It should not cause any damage to the controller or drive, although this is possible.

If you don't have cd-rom drive or floppy drive on laptop and the hard drive is not booting up what do you do?

Some Systems won't boot because the BIOS has been crashed or altered in some way? Try getting into the BIOS setup page by holding the escape key while booting. If you get the onscreen prompts follow them in. Check to see if the Hard drive is recognized by the BIOS, you should see a description of your Hard drive somewhere within the settings. Most BIOS have an AUTO detect function some where make sure it does. If that is all good, then you may want to have your Lap-Top boot from a Network device. Find a PC or other LT with IR (infrared connection capabilities) because your Lap-Top does (almost all do) set the good PC to share files and folders and alow access to the system files. Hopefully your LT will detect the IR port on the good PC and draw the boot info from it. You must be using the same OS on both PC's though. I have a sneaking suspicion you are using Windows 98 on a PC running 300-500 MHZ with 64-128M RAM? Windows 98 is notorious for crashing if you mess with files using software like Registry Mechanic or others.Otherwise invest in CD for your lap top and I find it hard to believe it never came with a CD or Floppy!

How do you still use Socrates ideas today?

Foreword

This Introduction to Philosophy has three main components:

1. an introduction to philosophical thinking as such through a presentation of the work of Socrates;

2. a narrative description of the world in which Socrates lived, the society of classical Athens;

3. an application of Socratic ideas in later developments of Philosophy, particularly today.

A few words about each of the components:

1. What is Philosophy? The literal translation of the Greek word "philosophia" is "love of wisdom" (from "philos"= love, and "sophia"= wisdom). That origin of the word is still highly relevant, as will be seen, but not quite sufficient for a definition of what Philosophy is. Obviously, one needs to know what constitutes wisdom before one can know what a lover of it is.

The word "wisdom" can have several meanings. In ancient Greece it could mean, for example, the thorough knowledge of such things as mathematics, astronomy, literature, and music. A wise man in that sense was a person who knew a great deal more about these things than most other people. The wisdom that is relevant for Philosophy, however, is somewhat different. It is a special kind of thoughtfulness--a thoughtfulness that can be described as follows:

When people think about themselves in a serious way they often take, as it were, a step back from themselves and their lives and ask such questions as: Is this the person I ought to be? And does what I do most of the time ultimately make sense? Is what I live a real life? (Time and again inquisitive people have wondered whether there is real life before death ....)

Widening their inquiry from personal matters to broader concerns, thoughtful people will ask: Is this society, of which I am an active or passive part, the society I want it to be? Is it a good society? Is it just? Are there meaningful alternatives to our way of life? And what exactly is justice, anyway?

Widening their awareness still further, people develop such questions as: What are the ultimate goals of humanity? What is the meaning of life? Is there any meaning to life?

The pursuit of these questions will quickly bring up such related questions as: How can one find valid answers? What can we really know? What exactly is knowledge?

Organized religions and social traditions have shaped most of the moral concepts and rules by which people live. Different religions and different societies often seem to differ, however, in what they consider to be good or bad. What is good in one society is often considered evil in another. A thoughtful person will not want to be naiv or arbitrary about any such moral convictions; a thoughtful person will ask for convincing reasons why the moral demands of this or any other society should be accepted by free and intelligent beings.

Philosophy is the activity of seriously asking such questions, and of possibly answering them. Philosophers are individuals who do not blindly pursue their everyday purposes within the confines of unquestioned beliefs and established practices, but who look beyond everything that is given in order to inquire about ultimatepurposes and justifications. They are not content with what people usually accept as justifications, but try to go beyond such convictions to determine whether accepted justifications are in fact sound. To be a philosopher is foremost to raise critical questions where most people simply believe and accept. It is to be a professional skeptic--and to accept answers (if at all) only after an intensive investigation of all reasons for doubting generally accepted convictions. Philosophy, one could say, is the art of doubting what most people rarely or ever doubt: the foundations of their everyday lives.

The first well-known thinker who explicitly and systematically introduced this kind of questioning into Western civilization was Socrates. The basic principle of his activity as a lover of wisdom was his often quoted statement "The unexamined life is not worth living." Socrates thus defined Philosophy as critical self-examination, as the will to not just live life, but to constantly question and evaluate it at the same time. Life, according to this conception, does not consist in simply existing in the world, but in developing a conscious relationship to this existence. Human beings should not be just doers, but should exist more as knowers, as knowers of themselves and their world. They should not pursue their practical goals like the instinct-driven creatures of an ant hill, but rather deliberately and reflectively--with a comprehensive understanding of what their lives and activities are ultimately about. Socrates thus set new standards for what it is to be human. The teachings of Socrates imply that people can fail, and fail utterly, to be human beings.

By systematically and persistently asking such questions as "What is (true) virtue?", "What is (true) justice?", or "What is (true) knowledge?", i.e., by casting doubt on commonly accepted notions of virtue, justice, or knowledge, Socrates more or less created Philosophy as we know it. After Socrates his friend and disciple Plato did not have to do much more than to add some more questions, and to attempt some famous and infamous answers, to delineate the body of concerns that constitute the core of Philosophy to this day. After reviewing the work of the philosophers that contributed their efforts during the twenty-four hundred years, the 20th century philosopher A. N. Whitehead concluded: "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." Socrates's work has never become outdated (in the way in which ancient Greek astronomy, for example, has become outdated). Socrates's questions and teachings are as relevant today as they were in 5th century Athens. It is for this reason that an introduction to Socrates's thoughts and activities is as pertinent an introduction to Philosophy as an account of more recent philosophical endeavors. To understand Socrates is to understand Philosophy--at least in its Western form.

2. To start the study of Philosophy with Socrates does not only have the advantage of clarifying an important beginning of Western thought, but also of providing an insight into the reasons why Philosophy ought to be pursued. In studying the discussions that Socrates had with his friends and opponents we learn not only what philosophers think, but also what prompts their arguments and pronouncements. Philosophy rarely exists in a social vacuum; it usually emerges in response to problems and challenges that come from the outside world. In the case of Socrates that becomes particularly clear, as all his thoughts are not the result of writing in solitude, but of discussions with others--of direct social interaction.

Plato (the main biographer of Socrates) provides a great deal of social context for the thoughts of his teacher, even if some of his descriptions are fiction. He presents a fascinating picture of the society that brought about Western philosophy. Since Plato could presuppose a great deal of knowledge of classical Greece that later became lost, however, further historical material has been added here. The history of Athens at the time of Socrates is a significant and suspenseful story, a story that can be reconstructed from the writings of Plato's contemporaries, particularly from the histories written by Thucydides and Xenophon. These histories, as will be seen, add much meaning to the philosophical deliberations of Socrates.

3. For Socrates Philosophy was a matter of how to live one's life. In subsequent centuries the love of wisdom became a great deal more academic, something that could be as remote from people's practical concerns as a game of chess. One reason was the increasing degree of specialization that befell Philosophy as much as any other area of knowledge. Professional philosophers could fill volumes on the question of whether a falling tree makes a sound if nobody is around to hear it--without being able to say how an answer to this question would make any difference to anyone. Philosophers can argue such a question from nine to five and then live as unphilosophical a life as anyone else. Another reason is the growing historization of Philosophy, the tendency to painstakingly research what others have thought about a problem, and then consider the result as an accomplished task of Philosophy.

"There are nowadays professors of philosophy, but not philosophers," Thoreau writes in Walden. And he adds: "To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, .... It is to solve some of the problems of life, not only theoretically, but practically." There would be not much sense in studying the thought of Socrates if one could not learn something important from it for one's own existence. Philosophy should make a difference in people's lives, and not exhaust itself in the contemplation of quaint puzzles or the satisfaction of an antiquarian curiosity. An application of Socratic ideas to situations of our own century is therefore an essential part of the present Introduction to Philosophy, an application that will actually highlight the very meaning of statements that would otherwise be nothing but cultural window dressing in an otherwise barren and uninspired life.

Where can you go to print photos off a floppy disk?

A computer tech store should be able to help load the pictures off of a floppy disc. After the pictures have been uploaded to the computer and reloaded on a CD the pictures can be print anywhere that prints pictures.

What is a destination disk?

When you do a data export, or create a table, move a table, move a file, ftp a file, etc., you need to specify in the command where the data will go. This is the "destination" disk. This disk will be a named object. My disks are called: $D001 $D002 So, my create table statement would include the disk specification in the statement: create table $D001.VOLUMENAME.TABLENAME field specs table attributes;

What is the index hole on a floppy disk?

The index hole is the computer's way of knowing where the starting point of the sector was on diskette by physically having a hole punched in the film disc within the plastic casing.

Why is it a good idea to write protect a floppy disk?

It is a good idea to write protect on a floppy disk because it is a back to make sure the disk doesn't get overwritten. A disk can also be write protected by pushing a small tab on top of the disk to reveal a hole.

Can you get data off of an unformatted A drive disk?

If it were never formatted, there should be no data on it.

Answer

as an update to the previous answer, there can in fact be data on an unformatted disk. I am currently seeing the same issue right now...files on an unformatted disk but am unable to recover...read on.

AnswerThe disk has to be formatted in order to place information on it. Different systems had their own formats, and they weren't always compatible. If you see files on the disk, you can copy them over to your hard drive and then try to run them. Look at the extension on the file to see what program would be able to open them up. Examples of extensions would be Word (.doc), Excel (.xls) and so on.

What does it mean to over write on a floppy disk?

If the same data is already in the floppy disk or any other disk, and you are again copying the same data, then it is called the overwriting ..

What is the function of a plastic flap of a floppy disk?

The purpose of the plastic (or metal) shutter on a floppy disk is to keep dirt off of the magnetic medium when it is not being read.

How do you make a floppy disk read only?

There is an easy way to change a floppy disk to read only. Just go into Explorer, right click on the floppy disk, and check the 'read only' box.

Explain the process for copying a file to a storage medium floppy disk USB storage medium or CD-R drive?

The process of copying a file to a storage medium is actually quite simple. I like to use window explorer. Once you find the file you want to copy right click the folder and then click copy. Then find the file under computer that has your USB (storage medium) right click it and then click paste. The file has been copied. Copying multiple files is very much the same, but when you need to hold the shift key down each time you select a file. Once you have chosen all you files and they are highlighted the steps are the same.

What are the disadvantages of a hard disk drive?

Since your question only requests the disadvantages, they are as follows: Consumes alot of power, the resistance of shocks is low, data error rates are frequent, weight ratios are large, the size is large, can be hard to recover data from, (SCSI) controller cards may be required, loud mechanical noise can be generated, heat can be generated, there are moving parts inside, the disk sectors will eventually stop working, and they can be broken if dropped (usually whilst operating). The speed of the Hard drive speed (MBS) can regulate the data transfer rate of the computer. If the jumper settings are not precise the hard drive may become fried. If you have a hard drive which is older you may find it hard to find the hardware drivers for it. Also if you have a hard drive which is older it may cause data to be corrupted on your computer and you may lose your data because of faulty transfer to/from the disk platters.
