Three Dimensions to Protect your Computer


This article will talk about how to protect your computer from three dimension, Strengthen the denfense, Against from Attacks, and Keep Checking Three Dimensions to Protect your Computer



First - Strengthen the defense of your computer
- Install Firewalls
"Firewall" is an isolation technology to separate the internal network and the Internet. The firewall carries out some filtering when two networks communicate. It lets the data/person that you "agree" to enter your network, and also block the data/person you "do not agree" from your network. It can prevent they changes, copy, or destroys your material. To ensure the firewall get into work, you must keep it update.
- Install Anti-virus software
The key on computer virus is not "Kill" is "Prevent". You should install the Anti-virus software and start the real-time monitoring process and keep the software and the virus definition file updated. To guard against the newest virus, you should set the update process in a daily mode. Also, in every week, you should scan the computer completely for the virus.
- Guard against Spyware
Spyware is a program that is installed without the user authorization. It can get the information and send to a third party. Spyware can attached in software, executable image and break into the user computer. They are used to track the computer usage information, record the keyboard hits, or take a screen capture. To get rid from spyware, you can
- raise the security level of your browser
- install software to guard against from spyware
- verify with the official website about the software plan to install

Second - Against from attacks
- Refuse unknown software, emails and attachments
Don't download unknown software. Save all downloaded softwares into one single directory and scan it before install. Don't open any unknown email and its attachments. Many viruses are spread through by using email. Don't open unknown emails, especially those with interesting headline.
- Don't go to hacker and pornographic website
Many virus and spyware are come from these websites. If you browse this website and your computer is not secure enough, you can imagine what will happen next.
- Avoid share folders
Share folder is risky and outsider can surf around your folder freely. When you want to share folder, remember to set a password. If you are no need to share the folder any more, remove the sharing immediately. It is extremely danger to share the whole drive. If someone removes the system file, your machine may be down and cannot start up again.

Last - Keep Checking/Update
- Set different and complicate password
In Internet, there are thousand needs to use password, like e-banking, login account, email. Try to use different password for different operation, this can limit the loss if one of the passwords is broken into by someone. Avoid using meaningful password, like birthday, telephone number. You should use password with letter and number. One more thing is do not choose "Save Password" option.
- Beware of defraud
The number of defraud case in Internet is keep increasing. Build up a fake bank website, send out an email to ask for password. Before take any action, try to verify it is real or not. You can phone to bank hotline to ask, go to the bank to contact directly.
- Backup
Backup is the last step to guard against the attacks. If your computer is hacked, the operating system and softwares can be reinstalled. But the data can only be restored if you frequently make a backup.

What is Light ?

Light is a mixture of electrical and magnetic energy that travels faster than
anything else in the universe. It takes less than one lent of a second for light to
travel from New York to London. Light is made up of tiny particles of energy
called photons. The light moves along in very small waves that travel forward in straight lines, called rays. Light can travel through air and transparent substances, but can also travel through empty space. this is how sunlight reaches the earth. Light is similar to other forms of electromagnetic energy which have different wavelengths.


Radio Waves
These have the longest wavelength. They are used for satellite communication and to carry TV and radio signals.


Visible light
Appears white or colourless, but is made up of colours, each with a different wavelength.




Microwaves
Very short radio waves used in microwaves overs. They are also used in radar.




Electromagnetic spectrum
This show different kinds of electromagnetic energy arranged in order of their wavelength. Wavelength is the distance between two consecutive waves.






Infrared Rays
Invisible rays. but we can feel the heat from them. They can be used to detect cancer and arthritis, or to take photographs in the dark.




Ultraviolet Rays
These cause us to tan and help the skin to produce vitamin D. Large amounts are dangerous and may cause skin cancer, although most ultaviolet light from the sun is absorbed by the ozone layer.





X-Rays
Called "X" by their discoverer because he was unsure of their nature. they pass through flesh, but are absorbed by bones and teeth, causing them to show up on X-Ray film. Small doses are safe, but large amounts are harmful to living tissue.




Gamma Rays
These have the shortest wavelength. They are given off by naturally radioactive materials, such as uranium, and are part of the fallout after a nuclear explosion. They can travel through lead and cement, and damage living tissue.

7 "Secret" Keys To AdSense

by: Richard Keir
Copyright 2005 Richard Keir

There's a lot of buzz around about how you can make a quick and easy fortune using this AdSense course or that tool or this book.

And they show you their incomes from AdSense to
o (though not necessarily THIS month). Now, is it just me or is something a little odd in all this?

Say, I'm making $5000 - no make that $15,276 a month from AdSense on my sites. And now I'm going to sell all my secrets on how to do that for $67 or $97 or whatever.

So what happened, did I get all bored with my filthy riches and decide to become a philanthropist and sell stuff that makes me 15K a month for a pittance? Or is it something else?

Am I saying it's impossible? Certainly not. I know people who make that more.

But a little reality. Those people don't have 5 or 6 or 50 sites. They have maybe 500 or 3000 or more. Few sites make 20 or more a day. Very few. Average income is probably less than a dollar a day. So with 500 sites at a dollar a day, you've got your 15K a month.

Now the domain names cost you maybe $3500 to $4500. Then you need hosting and somehow you've got to build the sites and get traffic to them. There are excellent tools but the ones that will let you do this kind of thing in a reasonably short time are also very (very) expensive.

And you are continually dealing with sites that don't get indexed or get de-indexed or even get banned. Traffic today, gone tomorrow. Plus, if you're not real careful with those tools you may get an unpleasant letter from Google about a DMC
A copyright infringement which could cost you your AdSense account.

You can make money, you can build an empire. But it isn't easy or quick no matter what you hear. And it really isn't a business. It's not a long run proposition, it's not stable. You need to keep creating more sites as older ones fail - or you need to be smart and use those AdSense revenues to build an enduring business.

You put up with this down to here, so here are the real 7 "secret" keys to AdSense.

1. The best performing AdSense type is the large rectangle. This has been tested over and over.

2. The best colors are blue for the link - surfers know that blue means click me. And darkish almost black and grey for the text and url. No borders. The same background as your page. Will it merge into your content? No, that's bogus. There are maybe 4 surfers in this galaxy who can't tell a Google ad when they see one. They are not going to believe it's part of the text. Wake up, OK?


3. Another format which is being reported to more or less work is the full wide banner type layout with text ads and images directly above the links. Try it and see if it works for you. Maybe it's a fad.

4. Keywords and related content are critical if you want targeted ads. If you want high paying clicks you need to target the costly keywords AN
D have content that supports the keywords.

5. You need traffic interested in the ads. Which means your traffic generation techniques have to be targeted not scattershot. You might hear that 1% or 1.5% clickthrough rate is OK and 3% is good. Nonsense. Really successful people get CTRs that are often well above 30%. Even with modest efforts you should be getting an average 6 to 15% CTR (per ad impression, not pages).

6. You have to track what you're doing and you have to test variations in ad layout, placement, color and related content to optimize your income. N
o one can tell you how to do it except the traffic coming to your site. If you don't test and track, you're flying blind.

7. You need to keep building new sites.

You are now a member of the AdSense Illuminati. Quite possibly you already knew all that. So why are you looking for something else? Really. T
his is all you need to start doing it.

Probably any course or book can help you if that's what it takes to get you moving and doing. Ultimately, no one can really show you exactly how to do it. You're going to have to learn the ropes and put in the time.


Like everything in life - the greatest traffic generator, the ultimate course or the super MLM opportunity, if it sounds too good to be true, then it is. There's no magic bullet, no ultimate secret to buy. There's no easy, painless, work free, certain road to riches (except, maybe, inheriting it and that can be very hard on the heirs).

Whatever you do on the net, do it wide awake and with your brain actually functioning. The final un-numbered key is that a technique, a shortcut, an idea that will make what you do easier, faster, or more profitable - one single tiny thing - is worth more than any book or course costs. One useable idea and you've gotten a great deal. If you learned something you didn't know or had forgotten, then it's worth much more than you paid. There may not be any magic solution out there, but there are useful concepts, techniques and ideas. You just have to see them for what they are, and then get busy and really use them.
