In this article, we will look at the meaning, types and functionality of scanners along with a brief look at some of the most reputed names in the world of scanning devices.
Before having a look at the types of scanners, let us first understand what a scanner is. A scanner is a computer peripheral that analyzes printed text, images, objects an even handwriting for the purpose of converting it into a digital form. This obviously means a reduction in the amount of paperwork and protection against paper frauds. Moreover, the digital images created by a scanner can be shared between any number of users with complete ease and perfection.
Now that we have a look at the meaning of a scanner, let us now move to the different types of scanners in the present day market. The scanners are of different types such as drum, film, flatbed, hand scanners and modern day digital scanners. The usage of each of these scanners is solely dependent upon the type of usage, resources at hand and the quality of scanning results.
How does a scanning device (scanner) works?
The object or document to be scanned is placed on the scanner's glass plate followed by the closure of the cover. A reference point for ascertaining the document size is created by the uniform background of the scanner. The CCFL or xenon scanner lamp then illuminates the document to be scanned. The scan head comprises of the lens, filter, CCD array and mirrors. It is moved at a slow pace across the document with the help of a belt attached by a steep motor.
The head is then attached to a stabilizer bar, which ensures the absence of any wobbles/deviations while completing a single and complete document scan. The document image is then reflected by an angled mirror to another and the last mirror then reflects the document image on to the scanner lens that focuses the image via the filter on the CCD array. After this, the software of scanner assembles the corresponding images into a single scanned image.
Some of the leading names in the world of scanning devices are Hewlett Packard (HP), Canon and Samsung. HP has been a pioneer in the world of scanning technologies and has introduced several affordable, high-end and performance-oriented scanning devices for the benefit of the home as well as official users.
The HP Scanjet G3010, HP Scanjet 2400 digital flatbed scanner, HP L1950A photo scanner and HP Scanjet 4890 photo scanner are some of the most highly acclaimed products from the reputed house of Hewlett Packard.
Now you must be able to find a good photo scanner for yourself. If you are looking for the best quality scanning devices at an affordable price without compromising on the overall quality, then the HP scanner is the name for you.

AdSense: Make Money Online Without Selling
I think the title of this article gives the best definition that can be found for the AdSense program of Google.
Through its AdSense program Google let you earn without the need for you to sell anything at all to anyone anywhere.
Many persons, including who is writing this article right now, are making money and receiving checks from Google month after month.
And there are many internet entrepreneurs that are generating higher incomes from participating in the AdSense program than from the direct sales of their own products or services.
All right, you are thinking that I told you something that simply has no meaning as earning money without selling. How can it work?
The answer is simple, you are paid per click and not per sale.
The AdSense program of Google is a service that let you, and anyone else that provides some kind of content online, to become a publisher for the Pay Per Click advertising program they run.
You can see it as a triangle, where three different subjects are involved:
- Advertisers
- Google
- Publishers
The advertisers join Google PPC service (named AdWords) in order to promote their services or products to the huge audience that this giant search engine has each day.
They bid on specific keywords that are relevant to the services or products they sell and have their ads displayed on Google when searches are made for the chosen keywords. They pay to Google for every visit to their sites that comes from this promotion, so they pay for each click.
Google then opened another service called AdSense that is an addition to AdWords. It is a service for online publishers, and let you display on your web pages ads of the AdWords advertisers targeted to the keywords of your web pages. It is all done automatically when you add the simple code that AdSense gives you once you are approved for their service.
Once a visitor of your sites clicks on one link of the AdSense ads that your site displays the AdWords advertiser is charged by Google for the click, or visitor that is delivered to his site, and you are credited by Google a share of that money in your AdSense account.
So you are paid for selling nothing at all, but just for the click that the AdSense ad received in one of your web pages.
Of course the Google AdWords advertisers are very interested in selling the products and services they promote paying for every visitor sent to their site, and I sincerely hope that the clicks that increase my AdSense income benefit the advertisers that pay me through Google, but this anyway is not my concern or something I have to worry when I create my sites and add the AdSense code to them.
I am more interested in creating web pages that are interesting for my visitors and provide them useful content. I worry to provide them with explanations and links of good resources if I don't have directly the opportunity to offer them a product or a service, and the ads displayed by Google are an addition that can be interesting and useful for them and can increase my income.
I think it seems all very simple from the above explanations. One thing that is very important to know is that the Google AdWords program is extremely crowded and there are really a lot of keywords and key phrases with big competition and very high bids. This means that advertisers pay a lot of money for every single click for those keywords.
Of course also AdSense publishers can earn a lot of money if they have sites related to those keywords that receive many visitors and many clicks to the Google ads.
