Part I Cloze (0.5x20=10%)

Directions: In this part you are asked to choose the best word(s) for each blank in the passage. Write your answers on the ANSWER SHEET.

Comedian George Carlin has a routine in which he talks about how humans seem to spend their lives accumulating “stuff”. Once they’ve gathered enough stuff, they have to find places to store all of it. If Carlin were to update that routine today, he could make the same 1 about computer information. It seems that everyone with a computer spends a lot of time acquiring data and then trying to find a way to 2 it.

For some computer owners, finding enough storage space to hold all the data they’ve acquired is a real challenge. Some people invest in larger hard drives. Others prefer 3 storage devices like thumb drives or compact discs. Desperate computer owners might delete entire folders worth of old files in order to make space for new information. 4 some are choosing to rely on a growing trend: cloud storage.

While cloud storage sounds like it has something to do with weather 5 and storm systems, it really refers to saving data 6 an off-site storage system maintained by a third party. 7 storing information to your computer’s hard drive or other local storage device, you save it to a remote database. The Internet provides the connection between your computer and the database.

On the surface, cloud storage has several advantages 8 traditional data storage. For example, if you store your data on a cloud storage system, you’ll be able to get to that data from any location that has Internet access. You 9 need to carry around a 10 storage device or use the same computer to save and 11 your information. With the right storage system, you could even allow other people to access the data, turning a personal project into a 12 effort.

So cloud storage is convenient and offers more 13 , but how does it work?

There are hundreds of different cloud storage systems. Some have a very specific 14 , such as storing Web e-mail messages or digital pictures. Others are 15 to store all forms of digital data.Some cloud storage systems are small operations, while others are so large that the physical equipment can fill 16 an entire warehouse. The facilities that 17 loud storage systems are called data centers.

At its most basic level, a cloud storage system needs just one data server 18 to the Internet. A client, e. g. a computer user subscribing to a cloud storage service sends copies of files over the Internet to the data server, which then records the information. When the client wishes to retrieve the information, he or she accesses the data server through a Web-based interface. The server then either sends the files back to the client or allows the client to access and manipulate the files on the server itself.

Cloud storage systems generally rely on hundreds of data servers. Because computers 19 require maintenance or repair, it’s important to store the same information on multiple machines. This is called redundancy. Without redundancy, a cloud storage system couldn’t 20 clients that they could access their information at any given time. Most systems store the same data on servers that use different power supplies. That way, clients can access their data even if one power supply fails.
