Wireshark

 Wireshark is a free and open-source packet analyzer. 

It is used for network troubleshooting, analysis, software and communications protocol development, and education.

Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.


Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.



Wireshark is a data capturing program that "understands" the structure (encapsulation) of different networking protocols.

It can parse and display the fields, along with their meanings as specified by different networking protocols.

Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports.

Wireshark can color packets based on rules that match particular fields in packets, to help the user identify the types of traffic at a glance.

A default set of rules is provided; users can change existing rules for coloring packets, add new rules, or remove rules.

System.out.println In Java

System  is a class in the  java .lang package.  out  is a static member of the  System  class, and is an instance of  java .io.PrintStream .  println  is a method of  java .io.PrintStream . This method is overloaded to print message to output destination, which is typically a console or file. System is a class, that has a public static field out . So it's more like. public final class System { /** * The "standard" output stream. This stream is already * open and ready to accept output data. Typically this stream * corresponds to display output or another output destination * specified by the host environment or user. * <p> * For simple stand-alone Java applications, a typical way to write * a line of output data is: * <blockquote><pre> * System.out.println(data) * </pre></blockquote> * <p> * See the <code>println...

JSON (JavaScript Object Notation)

JSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Official website :- https://json.org/

Amazon DynamoDB : Fully managed proprietary NoSQL database service

 Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key–value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio. Dynamo had a multi-leader design requiring the client to resolve version conflicts and DynamoDB uses synchronous replication across multiple data centers for high durability and availability.  DynamoDB was announced by Amazon CTO Werner Vogels on January 18, 2012, and is presented as an evolution of Amazon SimpleDB. DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. If Auto Scaling is enabled, then the database will scale automatically. To prevent data loss, DynamoDB features a two-tier backup system of replication and long-term storage. Each partition features three nodes, each of which contains a copy of that partition's data. Each node also contains two data structures: a B tree used to locate items,...
