Three Most Dangerous Computer Viruses

A computer virus is a program that affects various areas of the computer system, making it function abnormally .Computer viruses can cause great damage to a computer. They affect the performance of a computer and lead to loss of data. Here are three most harmful viruses:


Melissa was the 1st mass-mailing virus for the new age of e-mailing. The virus became popular in the1990s. Created by David L and based on a Microsoft Word macro, the virus was spread in an email attachment form by the name “list.doc.” Clicking the attachment allowed the virus to replicates itself and looks for the Microsoft Outlook address book. It then e-mailed itself to at least 50 names on the list.


ILOVEYOU was perhaps one of the most dangerous computer virus ever made. It was a standalone program that used to replicate itself. Initially, the virus traveled the internet via e-mail and succeeded in crashing thousands of computers all across the world.


Sasser was discovered in 2004 and its main target was the windows operating system. Unlike other viruses, it did not spread through email. Once it attacked a computer, the virus looked for other susceptible systems. It contacted such systems, instructing them to download the virus.


Justification for Mathematics Standards

For mathematics education to become substantially focused and coherent, mathematics standards are needed. These standards are basically meant to improve mathematics education. They provide clarity and specificity.

Instead of very wide statements without explanation, the standards ensure that learners grasp not just the conceptual key ideas but also the organizing principles. This is done by repeatedly referring to the organizing principles in the learning process. These principles include place value and laws of arithmetic. Through explanation and continuous reference to the principles, learners are able to understand mathematics.

The standards also ensure that there is a sequence of topics and performances. The sequence followed is based on research-based learning progressions that determine how the learner’s knowledge, skill, and understanding of mathematics develop over time. It is important that the sequence is maintained so that the learners can understand the concepts.

To test the understanding of learners, the teacher can ask them to justify why given statements are true or to explain why a given mathematics rule is applied in a given mathematics problem. The standards ensure the learners begin with simpler concepts in kindergarten. The concepts progressively get more detailed as the learner advance education.


Online Math Resources

Most of the students do not like math because they have the perception that it is one of those boring subjects. Technology has come into play, to help out such students. The internet provides a wide range of math resources that can be used to make the subject interesting. The following are some of the resources.

Yummy Math

This resource brings out the application of math in real life situations, making it interesting and understandable. It makes use of videos, images, and real-life challenges. It shows practical application of math in life.


This website has a large number of math games that are interesting. It has various types of math types and different levels. The games offered by the website include Maths Invaders, Mine Mayhem, among others.

PBS Learning Media

This resource enables individuals to view math from a different perspective, hence enabling them to understand it. It makes use of videos and interactive resources including Math Magic and Money. All this site needs is for one to create an account with them and be able to access their services fast and free.

d) provides both free and paid material that aids children understand math.

The free resources include a Fact navigator which enables children to memorize the multiplication tables. It also enables them tackle quizzes and takes part in a number of games aimed at making them understand math. The games include Math ModelsPirates II, and Monster Multiplication.


Importance of Computer Science in the Society

While growing up, most of us look forward to being of benefit to society by pursuing careers in fields such as medicine and law. Although computer science is deemed by most people as not being directly helpful to society, it is one of the best careers for people who really want to change the world.

Computer Science should be recognized as beneficial to the society, just like the other careers. It is of great importance to the society in the following ways:

It has improved communication up to an extent that the world is commonly referred to as a global village. People can now send emails through their phones, and video conference to people in other parts of the world.

It has aided modern education whereby people can learn, research and submit assignments online.

It has come up with solutions for various problems by coming up with various software and by even improving the solutions by making services like ‘Uber’ be easily accessible.

It has enabled secure protection for people and organizations through offering digital protection. It also offers protection to the people by digital verification of fingerprints.

The above examples are just a few examples that show the importance of computer science to the society. We can’t deny it — computer science can be applied extensively to transform the world.
