Tech Conniption

Most of the important data are stored in electronic versions because they are secured and require minimum efforts to retrieve. Not only office, the computers have taken a center stage at home also. The data are stored in the local machines, hard drives or into an external drives like CD, flash drives or other external drives. It is this place, where PC support plays an important role in today’s life.

The PC support or Business it support play an integral role in any business’s IT infrastructure. There is a large number of companies which provide Business IT support solutions for your organization which includes PC support and Network support.

Data, or information stored on your computer, can either be held on fixed disk drives inside the computer or on removable media such as CD’s that can be inserted and removed. Removable media can be used to transfer files between computers or to backup the data already existing on fixed disk drives. There are three types of removable media: Magnetic, Optical and Flash.

Magnetic Storage

Magnetic Storage: Hard disks, floppy disks and digital audiotape are examples of Magnetic storage. They operate through a read/write head, which creates and reads magnetic impressions on the disk.

The downside…

• The magnetic impression only lasts for around five years
• The capacity of most removable magnetic disks is too low for many types of files

Optical storage

Optical Storage holds information in digital form that is written and read by a laser. All CD and DVD devices are examples of this.

The upside…

• Increased capacity: one Optical disc can store the same amount of data as over 500 diskettes
• Durability: they last up to seven times as long as Magnetic forms of storage

Flash Memory (Solid-State Removable Storage)

Solid-state memory (or Flash memory) is a high-performance plug-and-play storage device that contains no moving parts. It is found in digital cameras, video game consoles and digital audio players. You can use it in the form of USB Flash Drives to transfer or backup data. Flash memory is small, light and fast.

Backup

Backup is the copying of files onto portable media so that if your computer crashes, data won’t be lost in oblivion. Backup is usually routine in large businesses but is often neglected by individual users. Some suggest backing up data files and duplicating your hard drive weekly. It takes around 45 minutes to backup a 500-megabyte hard disk.

There are two options- Local or Internet backup. The following is a list of Local backup options. Most of these also double as devices used to transfer data between computers.
• Diskettes
• Zip Drives
• CD’s
• DVD’s
• Flash Drive

Internet Backup

Another backup option is sending your files to an Internet site for safekeeping. If your computer crashes you can simply download them from the site. Here are a few examples of such sites:

Backup Defender- www.backupdefender.co.nz
My Backup- www.mybackup.co.nz

N.B. The author does not recommend or endorse any of the above service providers.

Diskettes and Zip Drives

Diskette

A Diskette is a 3.5-inch removable magnetic disk. The older version, the floppy disk, is 5.25 inches square and flexible. Copying to a diskette is quick and economical.

Ideal for…

• Those who use their PC for personal finance – the diskette enables you to retrieve checkbook balances etc.
• Projects that need to be continuously backed up such as a film script, as it is a cheap alternative.

Not so good for…

• Some newer computer and laptop models that do not have a diskette or floppy drive installed.
• Large amounts of data as diskettes don’t have a great storage capacity

Zip Drives

A Zip drive is a small, square shaped magnetic disk that is ideal for backing up your PC. The 100-megabyte size holds the equivalent of 70 floppy diskettes. They also come in a 250-megabyte size

Ideal for…

• Duplicating your entire disc drive
• Archiving
• Storing graphic images or other large files
• Transferring large files
• Keeping certain data separate from files on your hard disk

The downside…

• They seem to be a fleeting technology – most computers do not have a Zip Disc drive installed and opinion varies on how long they will be around for.

Compact Disks

There are different standards of CD’s that have different capabilities. Just to confuse us they are recognized by seemingly similar acronyms; CD-R, CD-RW, CD+RW, DDCD and E-CD.

CD-R

CD-R (Compact Disc – Recordable) is a CD that can be recorded to only once. It usually holds 74 minutes of audio or 650 MB of data, although newer versions hold up to 80 minutes of audio (700 MB of data). If your PC has CD burning software and a compatible CD-R or CD-RW drive, the CD-R can be used in the same way as a diskette. However unlike a diskette it cannot be deleted or overwritten. Look out for CD-Rs that have an additional protective layer which make them less susceptible to damage caused through scratching.
Ideal for…

• Making music CD’s
• Storing photos
• Storing permanent data

Not so good for…

• Transferring files as they can only be used once

CD-RW/CD+RW

A CD-RW (Compact Disc Rewritable) and CD+RW can be recorded onto as many times as desired. Data can be overwritten and erased. Other than this, the CD-RW is identical to the CD-R. If it wasn’t for their finite durability CD-RW’s and CD+RW’s could be reused endlessly.

Ideal for…

• Transferring files
• Holding temporary data

Not so good for…

• Holding important permanent files-in case they are accidentally deleted

Double Density CD (DDCD)
This disc has a much greater storage capacity than an average CD-R or CD-RW.

Ideal for…
• Backing up
• Storing archival data

Enhanced CD
Enhanced CD (E-CD) is an audio CD with CD-ROM data added. CD-ROM data is added in the space not taken by audio. Recording artists can use this to include videos, lyrics, interviews or promo material. The E-CD can be played on a CD player but to view additional material you need access to a multimedia-capable device, such as a CD-i player, DVD-ROM, or CD-ROM drive.

Bridge Disks
A CD-Bridge disc holds extra information on a CD-ROM XA track. The disc can be played on either a CD-i player attached to a television, or a CD-ROM XA drive attached to a computer. Software such as Photo or a Karaoke CD player can provide lots of fun with the Bridge Disk.

DVD (Digital Versatile Disk): More than movies

Although DVD’s have become more associated with video, they can also hold audio and computer data; hence their name Digital Versatile Disk. Like the CD, a DVD is a 120-mm by 1.2mm thick disk. However the DVD has more tracks than a CD so holds far more data. CD’s have an unvarying storage capacity of 750MB, whereas DVD’s store up to 17GB.

A range of acronyms is also used to distinguish between the different types and capabilities of DVD’s available. These include DVD-ROM, DVD-R, DVD-RW, DVD+RW and DVD-Audio.
DVD-ROM

DVD-ROM (Digital Versatile Disc – Read Only Memory) is similar to a movie DVD, but is designed for computers. The DVD-ROM stores data in the same way that the CD-ROM does and is used in the DVD-ROM drive of your PC.

The upside…

• Larger storage space – hold more data than a CD
• Can be filled with nearly everything; video, music or computer specific data
• A base speed of 1.32 megabytes/sec

The downside…

• Many older computers do not have a DVD-Rom drive installed
• Can be recorded on only once

DVD-Audio

DVD-Audio (DVD-A) is designed for audio data and high-quality music. Its storage capacity is seven times that of a CD and provides at least twice the sound quality. Like the Enhanced CD, DVD-A can contain other data, providing the listener with extra information such as lyrics or images. DVD-A is predicted by many to replace the standard audio CD in the music industry.

DVD-R

Like the CD-R, the DVD-R (Digital Versatile Disc-Recordable) can be recorded on once.

The upside…

• A DVD-R can contain an assortment of information; video, text, audio and computer data

• A DVD-R can be played on your normal DVD video player but remember, if you have additional data not of the same format e.g. video and audio together, you will need a DVD-ROM or Multimedia player of some kind

• A DVD-R is read at the same speed as commercially made DVD’s

DVD-RW and DVD+RW
Similar to the CD-RW, a DVD-RW or DVD+RW (Digital Versatile Disc – Rewritable) can be recorded on, rewritten and erased multiple times. Other than this they are identical to the DVD-R.
DVD minus and plus are just different versions with the same functionality.

The Future of CD/DVD Storage

The majority of the technology industry predicts that soon DVD’s, with their larger storage capacity and faster access time, will replace CD’s. DVD-ROM drives are likely to be sold with new computer systems in the way that CD-ROM drives once were. However we are always on the cusp of newer technologies, such as the HD-ROM.

HD-ROM (High Density-Read Only Memory)

HD-ROM uses a more precise particle beam to write data. This enables information to be written on more durable materials such as metal so storage is virtually permanent. HD-ROM has hundreds of times the storage capacity of the CD-ROM.

Flash Drives

A Flash drive is a small portable memory stick that holds anywhere from 1Mb to 1GB of data. It is surprisingly lightweight and is often worn around the neck or carried as a funky key chain. They are compatible with any PC that has USB port and with Mac OS 9 and OS X, Windows 2000 and XP or Linux 2.4.17.

The upside…

• Durable – more so than CD’s or DVD’s
• No need for batteries or a separate power source
• Convenient – your computer should recognize the additional drive as soon as you insert it into the USB port
• Ideal for backup
• Larger storage capacity then many other portable devices
• More portable than ZIP drives, CD’s and Diskettes
• Quick transfer rate (approx. 1Mb/sec)
• Edit, rewrite, delete as many times as desired
• Help desk personnel can use Flash Drives as a portable toolkit that includes system updates and recovery tools.

The downside…

• More expensive than other portable devices
• Viruses – The portability and compatibility of the Flash Drive increases the chance of spreading viruses. In many cases viruses carried by a Flash Drive will not be detected as most antivirus software is reactive and only recognizes known viruses
• Theft – a Flash Drive can make it easier for data to be stolen from an unlocked PC
• Little Security – the size and weight of the Flash drive makes it very easy to misplace. Most have little or no security features and data is accessed easily. Some Flash Drives do have built in security; either a password or in some cases a finger print system – but this comes at a price.

As we continue to evolve into the world of e-mail that is part of our everyday life, sometimes little problems arise that bother the user. Previously we talked about returned messages and lost connections, both which can be aggravating, and supplied solutions. But there are a few more problems that can affect an e-mail user causing frustration and we will address these here, and again provide reasonable solutions to over come them.

Problem 1 – You Cannot Send a Message

Even when there is not a connection problem, you may attempt to send email, but find that it continues to remain in your outbox.

Solution

Typically this is a software problem, the result of otherwise unapparent damage or corruption to one or more e-mail messages. To address this problem, first copy any unsent messages as text. Then save them on the computer’s hard drive or a back-up storage medium. After all messages have been saved, highlight all the messages in your outbox and click on “delete” or “clear”. When clearing your outbox, start over. Just copy unsent messages from the text files, pass them into new e-mail messages and resend.

Problem 2 – The E-mail is Missing an Attachment or the Attachment Won’t Open

An especially handy feature of e-mail is the ability to send and receive attachments. Transmitting documents, photos or other such information can save time and money compared to the U.S. Mail or express delivery services. At the same time, attachments can be real headaches. A common frustration is to receive an e-mail message that refers to an attachment, but then find nothing is there.

Solutions

Often the best solution is to request that the sender try once again, since it is not unusual for the writer to refer to an attachment, but then forget to attach it. Even if this is not the case, your request might prompt the sender to re-think the attachment’s format before transmitting again. If the problem continues, consider asking the sender to paste the contents inside an e-mail message and try again. This may disrupt formatting, but can be an effective way to circumvent attachment problems.

If you see a message that the attachment has been deleted, it may be that your anti-virus software has detected a virus, and you’re better off without it anyway. But if you find that all attachments are indiscriminately being deleted, check your mail properties. If a box is checked that blocks all attachments, remove the check mark so that you can receive attachments. If you then receive a message from an unknown person, or if the message or attachment seems suspicious, delete the message without opening the attachment.

A related problem is to see that an attachment has been transmitted, but find that you are unable to open it. The causes (and thus the solutions) vary. In some cases, the problem is that the software used by the sender does not match that of the recipient. As with a missing attachment, a simple fix is to ask the sender to copy and paste the contents of the attachment within a follow up mail message. Even if formatting is disrupted, you can still get the gist of the information. You can also use your own copying and pasting process to reformat the contents, if that is important.

Another strategy is to save the document to your hard drive, and then open the software program that was used initially to create it. Once this program is in use, your computer may be able to recognize what had been the attachment, and open it. If you do not have the appropriate software loaded on your computer, you may be able to download it from the Internet; just follow the on screen prompts to proceed.

Problem 3 – You Have too Much Incoming Mail or Cannot Download What You Have

If you are receiving large volumes of e-mail, you may be vulnerable to several difficulties.

Solutions

Many Internet service providers place limits on the amount of storage provided to each user (although some have recently increased storage limits). If a pre-set limit is reached (perhaps because you’ve gone too long without downloading your e-mail, or have been inundated by SPAM or virus induced flood of messages), additional messages will be bounced back to those who sent them.

Of course the direct approach is to download your mail and then weed it out, but a smarter move may be to access your e-mail account via Web mail. That way you can see a listing of all messages and quickly delete any that do not appear to be of interest. The end result is the same, but this step can save a great deal of downloading time if you’re using a dial up modem. It also adds an extra measure of virus protection even if you have a broadband connection. Since you’re deleting messages from your ISP’s server before they ever have a chance to infect your computer, it’s like killing mosquitoes before they bite you – instead of afterwards.

If you do not have a Web mail account, it’s easy to get one. Simply go to a provider such as Yahoo (www.yahoo.com) or Lycos (www.lycos.com) and register. You can also use a site such as mail2web (www.mail2web.com) or webmail4free.com without even registering. Go to the site and enter you e-mail address and password. You will see a listing of all incoming mail, which you can read and then retain for downloading, or delete, as you choose.

A similar challenge may be caused by unusually large message. Again, this problem is more common with dial-up modems, where hefty messages may take an annoyingly long time to download. In the worst cases, you may find yourself unable to receive other messages, because the connection with the server where your messages are stored is severed when a time limit has been reached.

Use of Web mail can also do the trick here. Just log on to the third-party site, peruse the list of messages in your inbox, and choose the one that is the largest (most Web mail programs automatically list the size of each message). If the message seems of potential interest, open and read it, and then delete it. Or if it is obviously spam or something in which you have no interest, you can delete the message without even bothering to read it. Once you have removed the offending message, your other incoming mail will no longer be blocked.

If you do not have Web mail, an option is to contact your Internet Service Provider and ask for help. Once a customer service representative deletes the offending message from the ISP’s server, you can then download all remaining messages.

Also keep in mind that retaining too much e-mail can be an organizational problem, if not a technical one. Take time to delete e-mail that does not need to be saved for future reference. Allowing too many messages to accumulate wastes storage space and makes it more difficult to find important messages when you need to refer to them. For messages that merit retention, create a series of folders so that they can be readily located, and so that your inbox will not become too full.
