Floppy Disk Drive(FDD) vs Cloud Services (Ndrive and Webhard)
A floppy disk drive, also called a diskette or sometimes FDD, is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles (https://en.wikipedia.org/wiki/Floppy_disk). In 1952, It was invented by Yoshiro Nakamatsu, who is Japanese inventor, and this was commercialized by IBM in 1970’s (http://skhynix.tistory.com/835). At that time, this idea itself that we could store computer data outside a computer was really innovative even though the storage volume was relatively small, for example 5’25’’ FDD having 1.2MB. This invention made people share a lot contents such as useful software, computer games and so on. FDD was loved by many people but many drawbacks started appearing. They were the risk of loss and error, inconvenience of delivery, relatively expensive and many users also wanted more and more data capacity as software technology was getting improved. Consequently, this innovative invention had disappeared in the mist of history in 2011.
Nowadays, many people use Cloud Services, which means services made available to users on demand via the Internet from a cloud computing provider's servers as opposed to being provided from a company's own on-premises servers (http://www.webopedia.com/TERM/C/cloud_services.html). The most famous Cloud Services in South Korea is “Ndrive (http://ndrive.naver.com/index.nhn#view=login)” and “Webhard (https://www.webhard.net/).” The former is free up to 30GB for non-commercial users and the latter basically provides for commercial users with fee, even though there are a lot of free coupons. Many Koreans can store and share their data easily. They can access all of their backed-up stuff at any place, at any time, just if they can use mobile devices and there is little risk of theft, fire, unlike FDD. For example, many Korean young people often upload their photographs in “Ndrive” right after they take pictures with their smartphones and many Korean businessmen use “Webhard” in order to share their official information and data for real time collaboration. The only drawback of this Cloud Services, as I think, is security such as hacking. So some people use a removable hard drive, USB, or their own hard drive without connecting any external network, for the purpose of protecting their important data.
What is difference between internet and web?
The Internet, which is an abbreviation of internetwork, is a way of transporting content by linking your computer to other computers around the world. The Web is software that lets people use that content or contribute their own (http://www.computerhistory.org/revolution/networking/19/314). So I think that the internet means just massive network or server itself, while the web enables people to access huge amount of information. The internet itself has no hosting computer, unlike web site. In my opinion, it can be said that if the internet is a road network, the web is a car.
