Memory Stick
Getting the Most From Your Digital Camera Memory Card by Kevin Rockwell
Imagine taking your new digital camera on a vacation and then realizing that you can barely click 20-30 images at a go. So, what do you do to avoid such a situation? The answer to this question lies in the purchase of an extra memory card or two.
One of the important components of a digital camera is the memory card. Most digital cameras come with quite a low amount of memory and it is always better to include the cost of a memory card while purchasing a camera. There are several types of memory cards so you must check out the memory options available in the camera that you are planning to buy.
Also, remember that if the resolution of your camera is high, then you will also need a high capacity memory card. There is no predetermined number of images that you can store on a particular memory card. It depends on the kind of images, the file type of the images and the compression rate per photograph. Normally, a 128 or 256 megabyte card is adequate for the average photographer using a 3-5 mega pixel camera.
There are several types of memory cards available. Here is a list of the kinds of memory cards available in the market today:
·Compact Flash Memory Card: Compact Flash is a relatively cheap memory card. It is available in most shops and is compatible with a large number of digital cameras. It is very popular and is commonly used by camera lovers. These cards come with an in-built controller which results in high transfer speeds. However, in order to use this facility, you normally need to be using a digital SLR.
·Secure Digital & Multimedia Cards: Commonly known as the SD card, these cards are one of the smallest memory cards which are available today. These cards can be used in different types of equipment, i.e. digital cameras, phones, MP3 players and video cameras as well. However, the maximum memory capacity is only 512 MB. The difference between the SD card and the multimedia card is that, as the name suggests, the SD card comes with an additional write-protect switch for data security.
·Memory Stick: The memory stick is an invention by Sony. As a result, these cards can mostly be used only on Sony devices. Hence, if you have a Sony digital camera, a Toshiba laptop; then it is most likely that you will not be able to use your memory stick on both equipments. It is a very durable and rugged memory option. So, unless and until you are a Sony fan, the memory stick has limited use for you.
·Card Reader: Once you have purchased a memory card for yourself, you will also need a card reader in order to transfer your pictures onto your laptop or PC. The advantage of a card reader is that it can be directly attached to your computer through the USB port. Then you simply need to slot in the memory card into the reader, and you can transfer files easily. The card reader does not require any additional cables and neither does it use up the battery of your digital camera.
The bottom line with digital camera memory cards is that you need to always have more on hand than you need, prices are often very affordable, and you should choose your camera based on the version of memory card that it takes. Don’t buy into a camera system if you feel the memory card will not accommodate your photo taking needs.

Why Tape Backups Are Obsolete in Today's Schools
by Chris Schutte
Most schools use tape to backup their important data. Tape is a form of magnetic media in a linear form, similar to VHS tape. It is not very quick or inexpensive, and is not extremely reliable. In the past though, it was just about the only form of removable media that had the capacity to hold an entire network's data.
To keep things reliable tapes need to be alternated in a rotation and then replaced about once per year. This costs quite a bit of money just for the media, not to mention the extreme prices for the drives themselves.
Tape drives are also very slow, and constantly need to be tested and monitored to make sure that they are really backing up and that the backups actually work. I have seen many cases with servers going down and the tapes being corrupt.
Today, there are many different forms of removable media. If you have purchased a hard drive or a flash memory stick in the last few months you have probably noticed that the cost of these devices has dropped significantly.
I recommend using external hard drives for backup. A 200GB drive can be purchased for about $200.00. This is by far cheaper than tape. By using a rotation of multiple external hard drives you get a form of backup that is much faster than tape and can be taken off-site. The backups can be checked by just browsing the drive, similar to browsing your C: drive.
External hard drives work with most backup software, and some drives even come with their own. Switching from a tape based system to a drive based system normally requires very little modification to your current system.
In summary, external drives are faster, easier to verify, and much cheaper than tape. When it comes time to upgrade your schools data backup system do a comparison between tape and external hard drives. I think you will see that unless tape drive manufacturers makes some big changes they are quickly on their way to becoming obsolete in the school market.
