History shows that in 1982 a man called Rich Skrenta made the first virus and put it “in the wild”. This means that the virus infected systems other than the one where it was created and tested. Today experts tell us that we are loosing the war against the viruses. Mikko Hypponen who is believed to be with much influence in Internet says: “This is not just a battle between manufacturers of security software and some internet criminals. It is a war between good and evil”.

Microsoft describes the virus as a small program designed to interfere with the computer system and usually take control over it. One of its main functions is to spread around the net to other users and for this it usually uses the e-mail software or instant message tools.

The damage that a virus could make is usually permanent. It can erase data, it can change it on a way that is no longer useable or it can delete your whole hard drive. Some viruses of course don’t target the data. They spy on your activity and warn their creators about it. In fact we can’t predict what the next virus could do. It is a program like all your software. It can do anything.

When talking about viruses most inexperienced users imagine horrible things because the very word virus terrifies them. Others take it very lightly saying: “What is the worse that can happen? I’ll just reinstall some software…” But where these frivolous thoughts end and begin the real problem?

To be infected could be a crime by itself. Imagine yourself working on a big corporation that in every moment dependents on the Internet and on every computer system in it. If your system is infected the infrastructure of the corporation is at stake because you are part of this infrastructure.

If we check the news we will see things like ReverseClick.A is a Trojan that disables some of your primary programs like task manger and registry editor, it swaps you mouse buttons and do a lot of things that you won’t like. XPCSpy can hide itself using some advanced technologies know as rootkits, Piggi.B conceal itself in the well known browser Internet Explorer and every time the user runs it the system is “updated” again with the virus code. The list of news goes on and every day new viruses appears to threaten our systems.

“When this will end?” you may ask but no ending is foreseen. The only protection against viruses today is the anti-virus.

Anti-virus is software that works on different modes. In real time mode it checks all system activity and looks for malicious codes that are executed in the system. In scanning mode it can checks all files for the core code of different viruses or parts of them. Usually good anti-virus software can prevent most infections before they are able to do damage. It is very important for the protection software to be updated on regular bases because it uses different virus definitions that you need to have. In a bad day anti-virus companies receives more then 40000 possible virus codes and they work very hard on making a definition and a way to disinfect the system. This is why an update is always required and a good way to do that is to set your auto update option on.

There is no way to be sure if your system is clean and you are safe to work. That’s why many people choose to have some experienced people working for them to prevent data stealing or deletion. One good virus removal company is Rescue Techusa .

What is the probability that at least one of the computers selected is defective?
Question 2: (with the same information)
What is the probability that exactly one of the computers will be defective?

= 1 – P( none are defective ) = 1 – (78/105)= 27/105= 9/35

Many of us sit at computers for long hours at home and at work. We get used to less than adequate equipment and often think that our aches and pains are normal. Not the serious kind of pain that comes with carpal tunnel and can’t be ignored, just a stiff neck more often than not, a chronically tired lower back and maybe a little eyestrain, for example.

We get used to the kind of chair we sit in and the height of the computer we live with hour after hour…day after day. We usually don’t even think about the brightness setting.

Ergonomically designed chairs quite often come with healthy price tags yet it’s a simple kindness to your self to check them out on the web and find a place where you can go try them out. Go to several different places and talk to their salespeople.

Some authorities say your monitor should be around two feet from your body. Where is yours? Have you ever given it any thought? Have you ever asked someone to help you measure to see if your eyes, when focused dead ahead, are one inch below the top of your PC, as recommended?

How about your lighting? Are you putting up with fluorescent tubes just because they’re “there”? Is there anything that can be done about that?

People who wear bifocal and trifocal glasses often have a lot to cram into a small field of vision. It may be wise to get a pair of mid-range glasses to keep by your computer to give you a broader view of your screen without having to hold your neck in a single position for protracted periods of time.

Whether you work at home or in an office that is provided by another person, you have the right to look closely at the long-term Health and comfort issues connected with your job. Check out available seminars on the subject and see what you can find out that may pay off both now and later on. Retirement may seem like a long way off and maybe it is, but you will want to be able to play when the time comes.

What do experts recommend regarding how long you should sit at a time and how you should stretch and exercise when you get up and move around? There is information out there that relates to the specifics of your particular situation.

The point is, don’t “just sit there” and wish years from now that you had been more pro-active. Now is the time to check it out and do something about it.

i would think that there should be a market for an operating system that has less function, and uses fewer cpu cycles.
unfortunately, such a system may well not be profitable.
a) because people will simply copy it and not pay, or
b) because people will not find the lack of much of the current function acceptable.

Only a few years ago, the PDA concept was introduced for the first time. The first Palm Pilot’s his the market and millions of people were hoped right away. The combination of a personal electronic organizes along with a powerful computer was a great solution for many people who were looking to get more done without sitting down with their lap-top or desk-top computers.

Later on, the wireless PDA’s were introduced, causing even more stir, and the PDA’s became even more sophisticated, allowing their users to surf the web wirelessly, download and send e-mail’s and the like.

But then – the wind shifted.

It had became apparent the PDA’s could not replace the notebook computers, that were getting thinner, lighter and cheaper, while offering the users the same abilities of a regular PC, but in a mobile fashion. A PDA, as good as it can be, can’t replace a PC.
So at this time, the PDA industry was standing at a crossroad. It had to make the right choice in order to survive.
And what we got as an answer to he notebook computer was the PDA, also known as the smart phone. This was a smart move, as it addressed people’s needs. Let’s take a look at a few reasons to own and use a smart phone:

1.You already use a cell phone, and you probably own a PDA (or intent to buy one). So why not combine the two? You get two in one – more value for your dollars.
2.You’ll probably save hundreds of dollar in future years, when you will want to upgrade your PDA phone. You will only need to upgrade one device instead of two (PDA and a cell phone separately)
3.Save time – Owning two tools that have so many over lapping function is time consuming. For example, It’s much easier to maintain just one email account and addresses instead of one of them at your cell phone and one at your PDA.
4.Many cell phones are limited in their memory capacity and their overall ability to handle various tasks. The PDA’s however, were created for these missions. The PDA phone therefore is a phone with a huge capacity for handling almost anything. This just makes your life a lot easier.
5.Integration – The biggest reason for merging these two vital tools is to enjoy the benefits of integration. You’ll be able to organize your calendar, talk to your clients, download emails, surf the web, and listen to an mp3 music file all at the same place without needing to switch appliances.

The PDA phone is a very logical choice for everyone who is trying to get more out of his day and save time and money. It really makes no sense to be carrying both a PDA and a cell phone around when you can have both in one.

You are looking into very advanced interfaces to do such a thing, and routers that can do that. are not regular all homes routers.

Another way, cheaper and free. is get utorrent.

www.utorrent.com

It lets you set how much "internet" or bandwidth you want the program to use.

Even for uploads.

So you can set it to maybe 100 kpbs for download, and 20 for upload. Doesn’t affect anything but what u just told it to.

Good luck
