The main goal of any hacker is to get some personal information or to use PC resources to send spam and viruses. I guess you have already got some viruses on your PC and, of course, any of us reinstalled Windows at least once because system efficiency became very slow. That is the result of viruses.So, how hackers deliver viruses to your PC?You always know how, but never follow simple rules:1) Do not visit URLs that you receive through IM or Email messages (even from friends, colleagues and family members). Make sure that they have sent you that first.2) Do not surf the sites with illegal content (adult sites, warez sites, etc.). It is much safer to order a paid product to escape problems with your Personal Information identity in future.3) Never download unknown files from the Internet because they can contain a for your antivirus software virus. It will not scan it and your PC will be infected.Recently, US specialists (CRN group and some others) found out that hackers can use VoIP services to hide Dos-attacks. Thousands of infected PCs transfer tons of traffic to a particular server very fast. The aim is to reboot it or to turn if off.The technology of VoIP services cannot be blocked by firewall of ISP that is why this is a high effective method for nowadays. Usually hackers use IM protocols for such purposes.Millions of people receive ICQ spam daily. This is the most widespread method that spammers use to deliver ads. But hackers use this technology too, so you should be very careful as it can contain a virus. While spammers just send advertisement messages, hackers in their turn send friendly texts to hook the attention of the user.Today, there are no any effective techniques to fight ICQ spam for full. You just may use different spam filters that are usually not effective at all. So, the best way to protect yourself from viruses and identity theft is to keep an eye open for the content in your messages. Check it twice before replying.So, where are hackers like to hide? In ICQ messages, in Skype and Vonage. They love all new technologies that are not secured in a proper way.All in all, hackers hack only those who are not prepared for their visit. So, be armed at all points and surf the Internet easily and freely.
Classroom technology can enhance the way they learn and influence how they understand and retain material learned. There are many forms of technology available that teachers can integrate into the classroom. An example of how teachers can use technology to their advantage when teaching is to create websites because it is now very easy to do so. Teachers have many websites available to host them and they include class notes online, school and teacher, educator pages and teacher website among others. These websites make it easy for teachers to start using websites as a form of classroom technology. However, teachers can also create websites by using the Microsoft Office Front-Page software program if they do not need hosting or want to control their own websites.Having a class website is an effective tool for teaching because students like visiting websites belonging to their teachers. Such a website can carry many functions for teachers. For example, it can list the assignments given to the students and make it possible for them to download it, teachers can display work created by students and communicate with parents. The students can also add content to such a website and teachers can have the option of opening it to other internet users.Another form of classroom technology that teachers can use effectively in the classroom is a web log or blog in short. The web log allows students to put in short information online regularly. A teacher can have a blog where students can read information that may be tips on homework, advice or any other information. Students can also put in their own entries into blogs that other students can respond creating a form of journal. Information passed on here will relate to the specific subjects taught by the teacher.The other form of classroom technology that teachers can effectively use is pod casting. Podcast work like radio shows where many people pass information. The information passed in the class will relate to lectures and the teacher may add music and pictures depending on the topic of discussion. The equipment required for pod casts is a microphone that one connects to a computer and software that allows for pod casting. The software is available for download. Students can podcast discussions or create podcast to share researched information. Pod casting also allows the students to interview people who may be more knowledgeable in the specific subject or topic that the teacher is teaching.Another type of classroom technology that teachers can incorporate into lessons is e-books. These are books available for download online and teachers can create e-books that the students can use. The steps to follow are to research information, put it on Microsoft Word and make additions that make it interesting and then upload it to Lulu. The students will then be able to access it. The use of such technology in the classroom will not only make the lessons interesting, but will also enhance the understanding of material covered in class.
