Standards and Wireless Notebook
All modern laptops are Wi-Fi, allowing access to the Internet from anywhere in the world. But while using your laptop Wireless should be aware of Wi-Fi standards, hotspots, and how to effectively use this technology to make optimum use of your laptop.
802.11g Wi-Fi is the latest standard, your notebook follows when you are online. The Wi-Fi alphabet spaghetti is made up of protocols such as 802.11, 802.15, 802.16 and 802.20. However, for notebook users 802.11 would be sufficient for an added '`,` b `, or` g'.
There are protocols as `e`, `h`, `i`, and `n` that are waiting in the wings to make its entry. However, as of now, 802.11g is the only protocol that you have to think with respect to wireless connectivity. The latest Wi-Fi standard is the 802.11g and offers connection speeds up to 54 Mbps in 2.4 GHz radio bands, which is five times more than the previous 802.11b standard. It is more stable, more secure, and backward compatible.
Almost all laptops that are manufactured today are standard 802.11g Wi-Fi. This rule is also designed to replace the older Wired Equivalent Privacy WEP or by specifying the Wi-Fi Protected Access or WPA. The WPA will function as a temporary solution until the new standard, the standard 802.11 network security is implemented with a new algorithm called Temporal Key Integrity Protocol, which will be much safer and reliable.
However, to apply the new standard, 802.11g is to follow. There are only two problems with This portable Wi-Fi standard, which first, because it is a new rule, can not perform as promised, and secondly, the latest technology quickly emerging, which may be obsolete by new standards before they take the time to benefit.
A few tips for a safe experience for Wi-Fi:
1 - You must raise the level of the laptop configuration. Raise the security settings of software applications like Microsoft Outlook and Internet Explorer. Update frequently to ensure the latest protection against hackers and viruses. You must have the encryption feature provided to ensure safer navigation Wi-Fi.
2 - Along with the software, you should also consider upgrading to better hardware. Hackers have always found very easy 802.11a to hack 802.11b. However, 802.11g is harder to crack and should consider upgrading your hardware to a "g" card. An 802.11g is backward compatible with standard IEEE 802.11b, 802.11g can therefore take advantage of the wide adoption of IEEE 802.11b international notebook PDA products. A personal firewall, such as ZoneAlarm or BlackICE can significantly add to the security level of your laptop.
3 - Whenever you're using your laptop in a Wi-Fi hotspot, make it a point not to send the data. While browsing do not enter your credit card number, expiration date, passwords, bank account numbers, data, so sensitive are gold mines for hackers, and you pass your bank account before he could finish saying, "I have been a victim of online identity theft! '
4 - Consider not staying online while working. If the risks outweigh the benefits, then it would be better to stay offline at least until the new 802.11i standard is not implemented. Still, security can be breached, albeit with difficulty. If you do not need to deploy Wi-Fi their work, then stay off. If you need the Wi-Fi just to send and receive files, then stay connected for only that period. Rest time, stay offline.
Precautions taken in a public access point Wi-Fi:
Whenever you are in public domain, it is necessary take precautions, because it is free to all. The access points Wi-Fi are available to any person and each and everyone can connect. Besides online thefts, There is also the risk of theft offline.
While in a public hotspot, do not be so engrossed with his laptop, not to notice those around you. There are people who are in the business of stealing notebooks, from public hotspots. And they do not operate as individuals but as a gang.
On the other hand, while connected to a public hotspot, follow simple rules like encrypting files before transferring or emailing them, sure it is connected to a legitimate access point and file sharing is turned off. The basic precautions like password protecting your notebook, update the system regularly, and use anti-virus software must be strictly followed. For online security, consider using a firewall staff, a virtual private network (VPN) and web-based email with secure http (https).
Having a good Wi-Fi experience directly translates into satisfaction Internet experience. These recommendations are being implemented, you are guaranteed to have a good time online with your notebook.

I have a male friend who says that we are close .. i trust him but he does not know much about my life .. Be some things about your life, but not all! we see every day, and have a positive friendship .. I wanted to have a more than "just friendship" but I did prefer .. So anyway, the other day I wanted to check out his notebook, it left my hand can not see anything in it .. if he says we are close, then why did he do that? I understand that privacy, but is there some other meaning?
Maybe he is really love you and has written poems about you or drawings to you in the notebook and you do not want to see it because you don "t choose what kind of relationship with Him
