Computer Viruses, Trojan Horse and Worms

Computer viruses can easily spread from one computer to another by attaching itself to programs and files. Do you know what greatly contributes to the spread of virus into you computer and to other computers? It is the action done by the user.

Viruses come in executable files. Meaning, it will not really affect your computer unless you run or open the malicious program. Oftentimes, because the user is not aware of malicious files and programs, they initiate it and this causes the activation within the computer.

There are a lot of anti-virus programs you can choose from which will enable you to protect your computer. Yet, it is still important to be aware about viruses because this will ensure that you can really avoid those malicious programs and files.

It is not enough to just know what a virus is. More importantly, you have to be aware of the other common threats that usually affect computers. Among the most common viruses are worms and Trojan horse. What exactly are these?

Worm is an algorithm which can cause damage your computer. The difference of worm among other computer threats is that is capable of spreading through your computer even without running or opening the program. It spreads from one computer to another through various methods of file transfer. What makes it worse is the fact that worms are often capable of replicating itself within your system.

On the other hand, Trojan horse is also another destructive program which can be quite tricky. Worms are capable of appearing in disguise. People who receive Trojan horse are often fooled into opening the file because it appears like a useful software or a program file from a reliable source. Trojan horse can do alterations to your computer like changing the desktop settings or adding unnecessary icons. In other cases, it causes more serious damage like deleting files in the hard drive.

If you think these two are already serious threats to your computer, there’s something else that is much worse. That is, if virus, worm and Trojan horse were put together in one seriously destructive threat which is also called as the Blended Threat. Blended threats are more sophisticated and more complicated to create. At the same time, it also has a more detrimental effect. It can spread through the entire computer and even to networks which damages the files and programs and can even sacrifice the safety of confidential information within the system. Even worse, blended threats do not need to be activated by the user before it could attack your system, destroying the computer, the network and programs.

Keep yourself aware of these things and it will strengthen your defense against the viruses that may destroy your computer.

How Do Viruses And Worms Affect Your Computer

Also, unlike viruses that most commonly infect an individual computer, the worms usually attack a computer network. A computer network functions by using a collection of servers and routers. This is what the internet is comprised of. A server is like a PC but has more speed and storage and a router is a server with specialized functions, it directs traffic through the network.
PC Security – Worm Viruses, Deadliest of All

A virus attacks the unit used to run programs on the computer called the central processing unit or CPU for short. It does this by running programs and being constantly busy, so that none of the functions you select can be opened. Similarly, this is how a worm functions on a network. The routers rely on memory and processing time (similar to the CPU functions). These are attacked and as a result the network drastically slows down.

Worms carry payloads which are comprised of other types of malware, backdoor installations or spyware. Spyware is a monitoring program that can keep an eye on activities on your computer and backdoor programs set up hidden access points used by hackers to steal your information or send spam.

My Doom sent out at the beginning of 2004, was the fastest spreading worm to date. The worm came in the form of an email with the message “andy; I’m just doing my job, nothing personal, sorry.”

Although the culprit was never found, its intended victim is thought to have been a software company called Santa Cruz Operation or SCO for short.

When a person opened this email, the worm was programmed to overwhelm SCO’s website with traffic. The worm spread through the internet and caused a massive slow down.

For the individual computer, the worm’s payload is more serious because it allows ports to be opened on the computer where hackers have access to steal or delete information. In addition, a payload may come with a program to attack your antivirus software and disable it.

De worming

Using firewalls will help protect your computer. Firewalls reduce traffic and hide your computer. In this state, you are less likely to be attacked by worms spread over the network.

Be careful not to open suspicious emails and if you don’t know the person or get and unexpected email don’t open it. If you find your computer is slow and reboots by itself or the internet is sluggish, you may have been infected. Try running antivirus software to check it out. If that doesn’t work, try to manually removing the virus. Information as to how this is done can be found on the internet.

Benefits Of Computer-assisted Instruction

Computer-based instruction and educational activities have been a part of high school level curricula for some time, but the primary grades have adopted these techniques a little slower. However, the adoption of technological learning activities will increase sharply over the next few years. Experts disagree on the single most important driving factor, but there are clearly a number of distinct advantages to computer-based learning activities over more traditional educational activities. Here are five of the most important.

The pace of instruction concerns everyone involved in the development of educational activities. Parents often worry about their child being either left behind or held back by the performance of the other students in the classroom. Teachers using traditional learning activities have trouble progressing some of the students in a classroom if not all are ready. Computer-based educational activities assist here by allowing each student to learn at his or her own pace. One student can move onto more demanding educational activities before the rest of the class without disrupting anyone else’s learning. Simultaneously, another student can repeat certain learning activities as often as advisable.

Computer-based instruction can also enhance the relevance and quality of educational activities. This will often register as a prime concern for parents and students. Collaborating with an appropriate site for learning activities will provide the school district or classroom teacher with a wealth of choices. With educational activities organized by grade level and covering a vast array of subject material, a valuable partnering site will empower the instructor with the ability to choose learning activities to target the students’ needs best. Further, if the site includes authoring tools, the teacher or parent may create new educational activities to address any under-served curricular areas. Additionally, a user community, if offered, may enable the sharing of learning activities far more easily than before. Providing instruction on the computer then helps foster increased relevance for the lessons involved.

To compete in today’s society, students need to achieve a much higher level of comfort and ease with technological tools. Today’s primary age students will find computers and technology dominating their workplaces to a greater degree than their parents or perhaps even their older siblings. Another advantage of learning activities on computers for our children then is that it teaches on multiple levels. Our students not only master the curriculum materials embedded in the learning activities, but also become more adept at using computers, which is also of value to them.

Finally, computer-based instruction can help lower the cost of our kids’ educational activities. Instead of buying multiple copies of a textbook for each subject matter area, schools can invest in computers and software to attend to all students. Many sites for learning activities can be accessed for a modest monthly fee. This one fee can then address an entire classroom’s needs across many curriculum areas at once, and therefore provide an economical way to provide educational activities. For these reasons, classrooms will feature computer-based instruction going forward.

Comparing Television to a Computer Monitor

When it comes to the appearance, a television (TV) looks exactly the same with that of the computer monitor. Maybe the difference will only be in the design and size but overall, similarities are certainly obvious. To give you a complete overview on the similarities and/or differences of these two devices, here are the top 5 major comparisons:

First, computer monitors such as Dell U2410 tend to have higher resolutions compared to most television sets. This means the picture element or other known as pixels is designed and measured perfectly to provide a high quality output. Computer monitors like Dell Ultrasharp U2410 are made using the modern method which means it follows the newest technology trend. Aside from this, computer monitors provide limited input options and comparing it to a TV set, it has a lot of input connectors which are placed sometimes in front, others on the side.

Another cool difference between TV and computer monitor is that the latter one do not have a tuner. All types of TV sets for whatever brand or model it may be, do have a tuner. What a computer monitor can only provide is the adjustment menu buttons. The Dell U2410 monitor is a good sample of an all-new computer monitor with adjustment menu buttons.

Another major difference between these two devices is that the television set were designed to have built-in speakers, while computer monitors do not. The function of television speakers is to release the sound when something is played on the television screen to give more life to the video.

Last but not the least, the fifth comparison between a computer monitor and television set is that computer monitors tend to be much smaller compared to most modern TV sets. Of course, it wouldnt be so comfortable if you have a very wide computer screen to work on right in front of you. This is the main reason why most computer monitors like Dell U2410 Ultrasharp is just wide enough to meet what our eyes can bear. However, there are some computer nowadays which are built to work as a computer monitor and as a TV set at the same time.

So if you think you need to have a monitor that you can work on and has a nice resolution, its best for you to have a computer monitor. But if youre looking for a much wider screen for video and movie viewing purposes, then the latest television set is the best choice.
