Explanation:
Big data refers to huge collections of data that are difficult to process, analyze, and manage using conventional data tools. It is a core component of the 3rd platform, which also includes cloud computing, mobile devices, and social networking. The five Vs of big data are high volume, high velocity, diversified variety, unknown veracity, and low-density value. Although SQL and relational databases can be used for big datasets, a collection of alternative tools referred to as NoSQL has become popular. These tools work well when databases scale out (horizontally) and when databases are broken into subsets called shards. Modern database tools also handle dynamic scaling as devices are added when additional capacity is required. NoSQL tools are sometimes said to create schema-less databases, but they usually have some type of structure, though it may be more flexible than the relational model. A key-value data model provides each data element with a key. A column-oriented data model makes it easy to access data stored in similar fields, rather than in individual records. Two very popular NoSQL tools include Hadoop, which is a big data file system, and MapReduce which sends processing logic to the data, rather than bringing the data to the computer that performs the processing.
The statement that encapsulation is the process of “packaging” information prior to transmitting it from one location to another is true.
This method augments the data with successive layers of control information before transmission across a network. Each OSI (Open System Interconnection) layer is part of the encapsulation by adding a header to the data packet in the transmission network.
Answer:
setTimeout is a native JavaScript function (although it can be used with a library such as jQuery, as we'll see later on), which calls a function or executes a code snippet after a specified delay (in milliseconds).

Answer:
Online or Web Proxy
Explanation:
Web or online proxy allows you to hide your Internet Protocol (IP) address from the website you are trying to visit or access. It is like a shield between the website you are accessing and you. They can be seen as a middleman between you and the site you are visiting and as such, the site sees that a specific IP address is accessing its server but the address is not yours as all requests between your computer and the web server are first passed through the proxy server.
