Data loss is an avoidable situation in which we have lost our data from hard drive. So the first question which comes to our mind is in what ways we are going to loss our data. If we have lost our data then what are the ways from which we are going to recover from such losses and finally what are the necessary precautions to avoid such losses again. So let starts with the basic question.

How data loss occurs

Data loss generally occurs when we delete our data from hard drive and it has also been cleared from recycle bin. If we format our hard drive then in that case also we are going to loose our data. And there are many unavoidable conditions in which we loose our data either due to software malfunction, viruses, file system getting corrupt or even sabotage.

In what way we can recover our data.

When data is deleted from our system, actually it is not permanently deleted. Data still resides in the data area of the hard drive only the entries on File system get deleted. Hard drive is divided into two parts system area and data area. Data are stored in the data area of the hard drive and entries of these data are maintained in the system area. System area consists of Root, Master Boot Record (MBR), FAT 1 (File Allocation Table) & FAT 2. FAT contains the entries of the data stored in the data area. Whenever we delete something only the entries get deleted. So there is data recovery software available in the market which scans the hard drive, identify the hard drive and give us the option to undelete it. Thus data recovery software is helpful in recovering data from any such losses.

Way to avoid data loss?

Data loss can happen anytime and anywhere. Best way of preventing data loss is to keep regular backup. We can use CD or DVD for backing up the data or using external hard drive. We can take some necessary precaution for avoiding data loss. If we hear a sound from our hard drive then we should not use any utility software, we should backup our data immediately and shut down the computer system to avoid damage to the drive and its data. Thus data back is the best strategy to avoid data loss at the first hand.

Launched on October 2001 as portable music device, Apple Ipod today, come in a range of varied shapes and sizes with some of the most advanced features to offer. The group of some of the most choicest music gadgets found world wide come with variety of functionalities. Along with the portable HDD-based flagship model of an iPod classic, there are ones in the range of iPod touch. Today, if there are ones like video iPod nano, with ability to show videos, there are iPod shuffle; simpler yet powerful enough to perform.

While the range of current iPod classic models play files saved on to an internal hard drive, there are other models that run using removable flash memory. Thus resulting in small size and increased ease of portability. While connected to a computer, these portable gadgets get recognised as external data storage devices.

To facilitate better listening experience Apple offers iTunes software along with the bundle. iTune software aids in easy transfer of music files to the iPods. The software also comes with a program that creates music library on the computer from which the data is gathered. In addition to playing and transferring songs from computer to the portable device, iTune software can burn and rip music from a CD as well. The same software also aids in fast sending of photos, games, and videos to iPods.

While an iPod is designed to play mp3 files, the series of these digital audio players also supports AAC/M4A, Audible audiobook, protected AAC, AIFF, WAVand Apple Lossless audio file formats. Now watch your photo in any of JPEG, BMP, GIF, TIFF, or even in PNG image file formats.

Several newer versions of iPod can also play videos in MPEG-4 (H.264/MPEG-4 AVC) and QuickTime format. Now if you are in a fix over playing a music in Microsoft’s WMA audio format just add a converter nowadays packaged with Windows version of iTunes. To play MIDI files also, one can convert the same with the help of iTunes’ ‘advanced’ menu. Once after installing a customised firmware onto the iPod, files in any of the open-source audio formats like Ogg Vorbis and FLAC can be played too.

The advancement of electronics has made various tasks to be carried out more easily and comfortably. One of its examples can be seen in the form of Internet and computers that connect millions of people from all over the world. Moreover in the advent of satellite channels, people have become more aware of the happenings in other countries. All these have been among various advantages of the electronic world in the life of a man. In other words, electronic world has marked a turning point in people’s life. However, the electronic development has not been stagnated here. Only there is constant development taking place in the world of technology with the passage of time.

The electronic development refers to engineering a simple design of a machine. But this is carried out by keeping in mind the requirements of a consumer. There are various points that should be taken care of while making a new product. This includes that it should be eco-friendly, minimal cost, comply all requirements of a user, PCB designs and many other issues.

There are many latest techniques in the world of electronics that have been invented. VCRs have been replaced by DVD player and DVD recorder. Moreover, there is also a trend of electronic voting. This involves usage of an electronic voter machine to cast a vote. These recorded votes are further counted by electric means only. This saves both time and effort required to be put in by an individual. It even speeds up the whole process of voting. This is especially beneficial to handicapped people who can’t walk up to a voting booth. This electronic voting technology makes use of specialized voting kiosks, optical scan voting systems and punch cards for the purpose.

Another development in the field of electronics is the use of digital signals instead of analog signals for the transfer of data and also various other purposes. Mobile phones, computers, cameras and many other products use the same technique. This technique makes available more storage space, and even lessens the wear and tear in the stored information.

Digital cameras ensure a better picture quality, more storage and even editing and transferring of the photographs on a computer. Moreover, the entertainment world has electronics as its foundation. Whether it is a radio, television, broadcasting of movies, news on channels, digital cameras, all have been a contribution of the electronics world.
