What is Domain Name System (DNS) in Networking
Networking , Technology & Science / March 8, 2018

As a critical component of the Internet’s infrastructure, the Domain Name System (DNS) is the translation system that turns an Internet host name (domain name) into the unique series of numbers which constitute an Internet Protocol (IP) address for each specific domain name. The DNS plays a critical role in supporting the Internet infrastructure by providing a distributed and fairly robust mechanism that resolves Internet host names into IP addresses and IP addresses back into host names. The DNS is a critical application for the reliable and trustworthy operation of the Internet. Domain Name System (DNS) enables you to use hierarchical, friendly names to easily locate computers and other resources on an IP network. Overview of Domain Name System (DNS) To send a packet to a remote host over the internet, knowledge of the IP address of that specific host is necessary, similar to the working of the telephone network where a phone number is necessary to reach a specific person. However, remembering the IP addresses of all hosts somebody might want to communicate with is rather difficult. Furthermore one probably want to reach a certain remote application, e.g. a website, regardless of the physical machine this application is running…

What is Simple Object Access Protocol in Web Services
Technology & Science / February 27, 2018

Simple Object Access Protocol (SOAP) is the messaging protocol for web services. It is used to encode the information in the request and response messages. A SOAP message is operating system independent and it is a way for one program to communicate with other programs independently to the operating systems of the other programs. The SOAP messaging framework consists of four parts, the SOAP processing model, the SOAP extensibility model, the SOAP protocol binding framework, and the SOAP message construct. The processing model defines “the rules for processing a SOAP message”. Overview of Simple Object Access Protocol SOAP supports different styles of information exchanged. It supports a Remote Procedure Call (RPC) style, which allows a request- response processing. And it also supports message oriented information exchange. This is good if you like to exchange business documents or other types of documents where the sender may not expect to get a response immediately. SOAP also have the following features: Protocol independence Language independence Platform and operating system independence Simple and extensible SOAP is an XML-based protocol from the W3C for exchanging data over HTTP. It provides a simple, standards-based method for sending XML messages between applications. Web services use SOAP to send…
