week 3 -secondary storage

when we built our PC, one of the most important thing we concerned is memory because it is the place to storing our data and it is also the bridge to the CPU. Now we already know we have different types of memory include ROM, POM, EPROM. Also ,we have three different storage way.Today I want to talk about some apply about the secondry storage.

secondary storage is not directly accessible to the CPU and is belong to the non -volatile memory that means they are premanent storage devices. The most usual secondery storge devices are hard disks, floppy disk, cd-rom.They are all good devices of back up the information.  Although sometimes we have backed up the data we can not make sure the system will never affected by the viruses. Then I think maybe the offline storage is the most safe way to back up the significant data on our PC.

off-line storage is a secondary storage and it can storage the data not under the control of the processing unit. Then we can unitilize this point to storage our data safely. But for a company it is critical that they have enough computer organzied memory so if they always depend on the off-line storage it will not working well in the end. so it is better  built a  company documents storage web site which uses the technology of cloud at the same time. Then they will never worry about the data can be loss.

week 2--- security privacy of the social media

It is easily found that in this society the most dangerous place is not a true place but a social media like face book or MSN. A lot of people utilize this space to cheat on others by stole their privacy’s at this time antivirus program becomes the most important software of PC. Although the antivirus program does helped us to prevent a lot of malevolence program sometimes we can found the file we do not want to be delete is disappear too.

If I have a company the first thing I want to make sure is our documents and the information of customer is safe. From my perspective, I think the software we used should enhance the ability to recognize which is the real thing could deletes. In order to prevent our equality was broken by the lawbreaker; just enhance the quality of software is not enough.

We should improve our judgments to the advertisement show up on the internet; nobody can cheat you if you do not want anything from them. If more people have cognition to make the internet a safe place there will have less crime rate because the lawbreaker would not get any profit from the cheat.

week 1- social media

    It is a information era, everyone use different social networks to make like more interesting. Just like facebook and twitter they make people's relationship become closer. But sometimes we just feel we are living in a virtual world since  maybe we are friends on the net but in the real world we do not even know what is the people  like. In this way we can explain why the thing like internet  defraud always happened. Let social network have more tightness relationship is a final goal of this era. Education and Business is two of the most siginificant field of the world now. why not utilize  the space of Internet to make this two field developed better?

 Now we already have the websites that the customer can use a account to submit the document and share it with other people, we have to admit it is a excellent product of the internate.  However, it still have some disadvantages, for example, if  I want to search a activity idea about how to hold a singing competition ,when the browse finished the search you can find the result shows a lot of activity idea is good but not suitable because different local habit. So why not classify them in broad catalog like location, business, study,  interested. After that we can bulid each topic a space, so everyone can join the space they ineresting. Like under the catelog of '' SAT exam" we firstly choose where is the location we are  then we can continue to go some more details point like "reading part". So the no matter where are you from you can always find the materials you are looking for.
 
In this way the people in different  place can know what other people think about the particular issue or assignment . Besides, they can also view the people in different part of the world have which kind of opinion .I think it is also a good way to learn different culture. For example, if we are all fans about movie" Front of the class" but the difference is I am from China and someone is from The  United States and we both need to write a paper about this movie, because we are from different place so we may have different opinion. Through this way we can know exactly what is different culture's have, so it is a good space for culture communication.
