Do You Feel Used by Computers?

Written by Lee Walder

Continued from page 1

At worst,repparttar used computers, as sold on to you, have minor blemishes, scratches, dents or wear. This is always just cosmetic and does not affect eitherrepparttar 138480 performance or value ofrepparttar 138481 computers in any way. What you receive is a fully-working computer,repparttar 138482 same working condition as new, but at a price well below that of new. You can often pick up recent high-specification models second-hand and save hundreds of pounds. Of course there are lots of bargains to be had whatever model or type you decide to purchase but note you will sometimes find it difficult to get anything as stock can go very quickly some weeks.

2. Unused Computers

The other main categories of computers arerepparttar 138483 overstock, surplus, liquidated, superceded, discontinued, open box or end-of-line stock. These are all basicallyrepparttar 138484 same in that they are all UNUSED computers. So these are not what you would really classify as second-hand, ie they have not personally been owned and used by any business, college, individual etc. They will often be in their original packaging.

The reasons why these computers come on torepparttar 138485 market are because:

- a manufacturer has brought out new models and wants to get rid ofrepparttar 138486 'old' superceded stock in his warehouse

- a store wants to raise some urgently needed cash and sell his unsold stock

- a factory or store becomes bankrupt andrepparttar 138487 computer stock is sold

In most of these cases,repparttar 138488 stock gets sold to specialist dealers who buy in bulk and who then sell it on torepparttar 138489 public, businesses etc. They then either provide a new warranty themselves forrepparttar 138490 equipment, or ensure there is a full warranty fromrepparttar 138491 original manufacturer. You'll often find Toshiba, HP, Compaq and other brand name computers offered with a 12-month warranty fromrepparttar 138492 original manufacturer. Note that sometimes suppliers refer to open box as meaning refurbished - they will usually state inrepparttar 138493 description what they mean.

So that's it. Two main categories of computers, quite different from each other but both offering great deals on branded equipment. Either way you will save money and still get a peace-of-mind guarantee on your computer purchase.

One last point. Make sure you check what you are getting for your money. Sometimesrepparttar 138494 computer may come without Windows installed or without a monitor. Don't assume - check. This will ensure you are happy with your savings AND your purchase.

BIG Squid RFID uses an integrated microchip and antenna that reads information. The combination ofrepparttar chip and antenna is called an RFID tag. There are two types of tags, and therefore two types of systems, active and passive. In passive systems, which arerepparttar 138431 most common, an RFID reader transmits an energy field that "wakes up"repparttar 138432 tag and providesrepparttar 138433 power forrepparttar 138434 tag to operate. In active systems, a battery inrepparttar 138435 tag is used to boostrepparttar 138436 effective operating range ofrepparttar 138437 tag and to offer additional features over passive tags, such as temperature sensing. The radio waves that are sent back and forth between tag and transmitter containrepparttar 138438 data inrepparttar 138439 tag, and this data is then converted byrepparttar 138440 reader and transferred into a computer system.

Companies are focusing on passive UHF tags, which costs less than 50 cents today in volumes of 1 million tags or more. Their read range isn't as far -- typically less than 20 feet vs. 100 feet or more for active tags -- but they are far less expensive than active tags and can be disposed of withrepparttar 138441 product packaging.

The Key Components to an RFID System are a number of components including tags of different sizes cateringrepparttar 138442 different industrial needs, RFID readers and system software.

An RFID reader, usually connected to a Personal Computer, servesrepparttar 138443 same purpose as a barcode scanner. It can also be battery-powered to allow mobile transactions with RFID tags. The RFID reader handlesrepparttar 138444 communication betweenrepparttar 138445 Information System andrepparttar 138446 RFID tag.

The BIGSquid RFID Software collects, permutes and storesrepparttar 138447 data collected fromrepparttar 138448 tag in a back end like MySQL, SQL Server etc. This is usually similar to any other data collection software.
