What is dropbox its working with benefits

Are you fed of storing your important documents and files in memory cards, pendrive or any other additional storage materials. If so then today I will be showing you guys about a very useful and reliable source of storing files and documents and also helps to share it with our friends circles, families and relatives. Now lets directly discuss about that service.
      Dropbox is a good and reliable service that helps in the storage of files and folders and share it with the relatives and friends. The storage is also available as in the form of cloud storage. The dropbox service is provided by American dropbox, inc. It was first time founded by Drew Houston and Alas ferdowsi who were the  former student of MIT. It was launched in the year 2007. Since then it has been providing its hosting service around the world. At first it was launched on a small service slowly and gradually it became bigger and began to expand.
       Basically it works on the principle as first it creates a folder in the synthesized dropbox hosting site and then it connects that server for the folder to all the computers who sign up to their hosting site. In the basic package the users can store up to 2 GB of data and in the premium basis they are given up to 1 tera byte of storage. It offers its service in all operating systems including windows, android, Mac, iOS and many others. According to a census of 2016 it has more than 500 million users who are using this service. Due to the open facility and some debugs it has faced many errors during the initial stage in addition of security preaching and leakage of the privacy. By now all the problem has been fixed and it is now it is one of the important hosting services in the world.
       It is very easy to use its services simply one have to go to its official website and sign up with the email id and name. After then a folder is need to be create and in that folder all the basic things are need to be uploaded and finally a basic or premium package is need to be selected according to our choice and we can easily upload and download any files by simply log in. It is one of the most valuated start up company in all over USA with an estimated valuation of 10 billion dollar.
        Hence this are the benefits and the working principles of the dropbox.

Ferro liquid clock and the working behind it

Ferro liquid watch better known to be ferrolic watch is a boon of science and technology. It is a scientific clock available in the different forms and it is at its top of a beautiful creation of art by the design of science. A thin layer of ferro liquid is placed behind a glass panel and behind that liquid are the numerous magnets that make the liquid to take digital numbers form. It looks very advanced but the principle of it is very simple. Before entering this lets first discuss about the ferro fluid.
          This ferro fluid was first time introduced by Steve papell who was then NASA researcher. This is the fluid of the rocket fuel and he first time noticed that the fluid was easily drawn out in the presence of magnetic field. Since then it get this name of ferro fluid. This ferro fluid is made up of very tiny ferro magnetic and ferric magnetic substances that are of the nano scale and that are present in the water as the freely suspended residue. It is a very big clumps available in the first but after that different filtration is undergone to make it a very small nano size particle. All the intermolecular force of attraction between the molecules of the magnet to attract opposite charge cannot overcome vander wall force of attraction as a result they need another magnetic field for the free moment of the molecules.
     In other sense the ferro liquid used in the clock us always perpetual since it is operated by the magnetic field to the ferro liquid. On behalf of this thing today this clock is gaining more and more popularity by the time. Since it is a good fusion of science and art thus it is very attractive and eye-catching. This clock needs no any other source of energy to move but simply a magnetic field. It can be damaged if it is brought near to a high magnetic field source.
      Due to this high popularity and a unique concept the price of this watch is slight high. It is available in $8500 around the USA, Russia, and many other countries. The clock tick tock of the digital number changes its form in each seconds. It has very less disadvantages due to this it is gaining popularity very much. The liquid is expensive due to this reason the clock is also expensive. This is the working of the ferrolic clock and the special liquid behind its construction.
