Adware and spyware, knowing the basics

People think that there is actually no difference between a spyware and an adware. Spyware is just a web term used to refer to an advertising supported software, which is otherwise known as adware. These are the pop-up ads that often come out whenever we open a website or download a shareware software. But according to some web experts, spyware is much much more.

Supporters of spyware and adware say that though it can be pretty annoying at times especially if you are really in a hurry, both do give consumers huge benefits. Because the product ads generate income for developers of shareware software, consumers can get them for free. Developers are in turn paid for their work. Of course, if you don't want to be bothered by the constant pop-ups, you can always pay the licensing fee or the regular fee for the software. If you want it for free, you just have to sacrifice through the spyware.

There is however another downside to it. Spyware, from the name given to it, is actually used as a tracking device in your computer system. These tracking devices will look into your surfing habits, your chatting logs and even the number of times you open your email. If designed or programmed the right way, it can discover just about everything else in your system. And because the program runs in the background, there is no way that a person can control the kind of information that he or she sends out.

These kinds of programs were actually originally used by parents or people in the business sector who wish to track down and put on record web activity. It is actually beneficial but not when people are not aware that they are being tracked down. This is often the case when people download software over the Internet. As mentioned before, it is used by companies to advertise their products and in turn help the developers of software keep their costs down so that they can afford to offer their programs for free.

Although privacy issues indeed come into play, there is nothing illegal about it. In fact, its use is prevalent all over the World Wide Web. There are however some areas that people who value their privacy will object to. Because of this, people are given the option to refuse the software.

There is really no way that one can avoid adware and spyware as these programs are packaged with the software that you will be downloading from the Internet. The most that you can do is to avoid downloading from the internet and to refuse any file downloads that you did not personally authorize. It is also good to only view websites that have a good reputation or those that have anti-spyware and adware programs installed in their pages.

A Simple E-mail Server

Given that you have an e-mail client on your machine, you are ready to send and receive e-mail. All that you need is an e-mail server for the client to connect to. Let's imagine what the simplest possible e-mail server would look like in order to get a basic understanding of the process. Then we will look at the real thing.



If you've read How Web Servers Work, then you know that machines on the Internet can run software applications that act as servers. There are Web servers, FTP servers, telnet servers and e-mail servers running on millions of machines on the Internet right now. These applications run all the time on the server machine and they listen to specific ports, waiting for people or programs to attach to the port. The simplest possible e-mail server would work something like this:

1. It would have a list of e-mail accounts, with one account for each person who can receive e-mail on the server. My account name might be mbrain, John Smith's might be jsmith, and so on.
2. It would have a text file for each account in the list. So, the server would have a text file in its directory named MBRAIN.TXT, another named JSMITH.TXT, and so on.
3. If someone wanted to send me a message, the person would compose a text message ("Marshall, Can we have lunch Monday? John") in an e-mail client, and indicate that the message should go to mbrain. When the person presses the Send button, the e-mail client would connect to the e-mail server and pass to the server the name of the recipient (mbrain), the name of the sender (jsmith) and the body of the message.
4. The server would format those pieces of information and append them to the bottom of the MBRAIN.TXT file. The entry in the file might look like this:

From: Radith

To: mbrain

Marshall,

Can we have dinner Monday?

John

There are several other pieces of information that the server might save into the file, like the time and date of receipt and a subject line; but overall, you can see that this is an extremely simple process.

Why the Need For Vitamin A

Vitamin A is an essential fat-soluble vitamin which promotes our eyesight and helps us see in the dark. It also aids in the differentiation of cells of the skin (lining the outside of the body) and mucous membranes (linings inside of the body). Vitamin A is important as it helps the body fight off infection and sustain the immune system, but it also supports growth and remodeling of bone.

If you body doesn't receive the needed vitamin A, then you could become vitamin A-deficient, which can lead to night blindness, bone problems, reduced immune system and health, anemia and unhealthy skin.

How much vitamin A is needed?
The Recommended Dietary Allowance (RDA) for vitamin A is measured in retinol equivalents (RE), retinol being the active form of vitamin A.

For men - 1000 micrograms of RE per day
For women - 800 micrograms of RE per day

Where to get Vitamin A from?
Most people would first reach for their vitamin supplements, but the best way to get your vitamins is from your diet.

Richest Sources of Vitamin A:

liver,
fish
liver oils,
milk,
milk products,
butter,
eggs.

Other Sources of Vitamin A:

A variety of dark green and deep orange fruits and vegetables -
carrots,
sweet potatoes,
pumpkin,
spinach,
butternut squash,
turnip greens,
bok choy,
mustard greens,
lettuce.

One thing to keep in mind - the absorption of vitamin A from the diet is improved when consumed along with some fat in the same meal.
