How Do Computer Hackers “Get Inside” a Computer? Abstract: It is very difficult if you want to simply explain how computer hackers “get inside” a computer. In this text, we will provide lots of details and analyze the way hackers use to invade into the computer. Generally speaking, there’re three patterns of getting inside the computer, which refer to gaining access to the stored contents of a computer system, gaining access to the processing capabilities of system, or capturing information being communicated between systems. As for the method, concisely, we can describe it as exploiting vulnerabilities, which includes known vulnerabilities, exist as the result of needed capabilities, and the unknown vulnerabilities, the result of poor engineering or arise from unexpected consequence of the needed capabilities. On the other hand, the unauthorized user must determine the specification of the target system, and then they can exploit the configuration’s known vulnerabilities. Of course, from the hackers’ method, we can also be enlightened how to limit and manage the vulnerabilities of your system in order to assure the security of the computer.Keywords: computer, unauthorized user, vulnerabilities, security.。

Mechanical energy is the energy that an object has because of its motion or position. For example, when you kick a soccer ball, the energy from your leg is transferred to the ball, causing it to move. It's like magic, but it's actually science!Next up is thermal energy. Thermal energy is the energy that comes from heat. When you cook food on the stove, the heat is transferred from the stove to the food, making it hot and yummy. Without thermal energy, we wouldn't be able to cook our favorite meals or stay warm in the winter.Now, let's talk about electrical energy. Electrical energy is the energy that comes from the flow of electrons. It powers ourphones, computers, and lights. Can you imagine a world without electricity? It would be so boring and dark!Last but not least, we have chemical energy. Chemical energy is the energy stored in the bonds between atoms and molecules. When you eat food, your body breaks down the chemical bonds to release energy, which gives you the energy to run and play.So, there you have it! Different types of energy that make our world go round. Remember, energy is all around us and it's up to us to use it wisely. Thanks for listening, and I hope you learned something new today!篇8Unit 3 Lesson 1: Living ThingsHey there! Today we are going to learn all about living things. Living things are everywhere around us. Plants, animals, and even you and me are all living things!Plants are living things that make their own food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to make their own food. Plants also help us breathe by releasing oxygen into the air.Animals are another type of living thing. They need to eat food to survive. Some animals eat plants, some animals eat other animals, and some eat both! Animals also move around and grow, just like us.Humans are also living things. We need to eat, drink, breathe, and sleep to stay healthy. We have different organs in our bodies that help us do these things. Our heart pumps blood, our lungs help us breathe, and our brain helps us think and learn.There are so many different living things in the world, big and small. Some live on land, some live in the water, and some even fly in the sky! Living things come in all shapes, sizes, and colors.So, next time you see a plant, an animal, or even yourself in the mirror, remember that we are all living things. Let's take care of each other and the environment around us. Happy learning!篇9Unit 3 SharingHello everyone! Today, we are going to learn about sharing.

Text1 How do computer hackers “get inside”a computerAbstract：Computer vulnerabilities are often utilized by hackers or crackers. The security of each computer is challenging. This paper firstly redefines the term “hacker”, “cracker” and “getting inside” the computers and describes the procedure in detail. The term “unauthorized user” (UU) will be a better choice for defining the insider group. The known and unknown vulnerabilities will be taken advantage of by UUs ranging from poor password protection to leaving a computer turned on and physically accessible to visitors in the office. The first step of employing technical exploits will be the determination of the specifications of the target system. There are two ways of attacking including being through capabilities inherent in hypertext transfer protocol (http) and being preprogrammed against specific vulnerabilities and launched without any specific target. The variability of hacking action including the weak system and the strong system warns the users to choose the right way to protect the computer and do not authorize the computer to others easily. Lastly, the solution of avoiding vulnerabilities has been given, including updating patches, making complex passwords, getting information only from the reliable websites or services, updatinganti-virus software and backing up the data to protect the computer not being hacked.摘要：计算机漏洞经常被黑客破解使用。

Abstract:This article introduces what is global warming firstly, moreover there is a dispute lies in whether or not the global warming caused by human or results from the natural turnabout. There is a series figure point out that during the past 70 years, the earth has been hotter than at any other time in the last millennium which only spend few decades. The rising temperature trend can not be explained simply , it’s a consequence of 2 centuries of pollution .What’s more, due to the inherent inertia of this trend,we cannot immediately stop but only slow down. In fact, carbon dioxide levels in the atmosphere are rising for a long time,moderating temperature swings and extremes, but our pollution is now strongly enhancing this greenhouse effect. However because the climate machine is complex, the sunspot cycle also play a role in it as well as volcanic eruptions. Attempting to pin down the true variation in global temperatures over the past thousand years is difficult because there still are evidences which can deny it.But of course , this was not the intention of the experiment at all . Indeed , it is only in recent decades that the pollution effect of human activities on the global environment has been thought of in these terms. Even if both temperatures and sea levels would continue to rise for centuries to come, we are going to face the changes to our environment. And our children and their descendants are going to find the earth a very different place.Key words: global warming , dispute , pollution, greenhouse gases, challenge.首先本文介绍了什么是全球变暖,并且对于人类引起的全球变暖是否是自然转变的结果存在争议。

The text attempts to point out various advantages of cloud computing .At the beginning,the author defines cloud computing as a pay-per-use model which quickly enables people to obtain access to reliable resources according to their demands.This process involves the least consumers’ management.No matter what kind of cloud is,there are 3 common features---being quickly allocated,having real-time backup and catering to requirements of clients.Then the text presents 3 varieties of cloud services:SaaS,which gains the largest popularity among cloud services;PaaS,which supplies clients for diverse goals with a platform;IaaS,which provides infrastructure on demand.Furthermore,the author describes benefits of cloud computing under green computing,which is regarded as energy efficient in using computing resources.Making full use of cloud computing can further facilitate green computing.Since cloud computing can be utilized to re-provisioning of resources,you needn’t purchase the infrastructure when expanding.Hence,you not only save expenses but protect environment as well since more electricity should be used to cool off computer resources as you buy more infrastructure.Cloud computing also makes telecommuting possible to your employees,which indicates large savings and promote greatly to environmentally friendly green computing.In short,the author comes to a conclusion on the basis of the above discussion,including 4 main advantages of cloud computing--remote accessibility,easy expansion,security and environmentally friendly.。
