The Internet is one of the greatest inventions in human history.However,this great invention has some problems.Everything you do online leaves a small track(痕迹).
Some people make use of the information you are providing for the Internet.How should you make your work online safer?There are a few steps.
Cover your tracks.Whenever you visit a website or a small file,a cookie(网络跟踪器) is marked in your browser(浏览器)
So what's the harm in the cookie?Well,bad people can use the information stored in your cookies to steal your passwords for some sites.So cut out all the cookies you have left as soon as you finish your work online.
Use the latest browsers.The main browsers,Chrome,Internet Explorer,and Safari are all built to be safe enough,but the people who create the browsers are not perfect and may make mistakes.It's common for a safety problem to come out with a browser.
Usually these problems are worked out very quickly,but it's important that you make sure your browser is up to date.In fact,new safety patches(安全补丁),but you need to make sure you have them.Turning on automatic updates(自 动升级) is the smartest choice.
Any technology has two sides.So we should be smart enough about them.
D To let your computer work faster and better.
