Short for HyperText Transfer Protocol, the underlying protocol  used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers  should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.The other main standard that controls how the World Wide Web works is HTML, which covers...

Abbreviated as BIND, Berkeley Internet Name Domain  is the most common implementation of the DNS protocol on the Internet. It's freely available under the BSD License. BIND DNS servers are believed to be providing about 80 percent of all DNS services. BIND was developed by the University of California at Berkeley. The most current release is BIND 9.4.2, and from Version 9 onwards it supports DNS SEC, TSIG, IPv6 and other DNS protocol enhancements.

Short for Domain Name System (or Service  or Server), an Internet service that translates domain names  into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.The DNS system is, in fact, its own network. If... Read full post

SSH Secure Shell provides users with a secure, encrypted mechanism to log into systems and transfer files; it can be viewed as a secure replacement for FTP.  Developed by SSH Communications Security Ltd., Secure Shell is a program to log into another computer over a network, to execute commands in a remote  machine, and to move files from one machine to another. It provides strong authentication  and secure communications over insecure channels. It is a replacement for rlogin,... Read full post

SNMP is the Simple Network Management Protocol.The SNMP protocol is used by network management systems to communicate with network elements.For this to work, the network element must be equipped with an SNMP agent. Most professional-grade network hardware comes with an SNMP agent built in. These agents must be enabled and configured to communicate with the network management system.Operating systems, such as Unix and Windows, can also be configured with SNMP agents.Simple Network...

Network File System (NFS) is a network file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer  to access files over a network in a manner similar to how local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The Network File System is an open standard defined in RFCs, allowing anyone to implement the protocol.
The NFS protocol is designed to be independent... Read full post

Based on feedback of Fabricefrom Squale, Please find a difference between Sonar and Squale
In a nutshell, we could say that Sonar is good at gathering code metrics and displaying them in various visualisations, mainly targeting technical people, while Squale is good at aggregating those metrics into high level factors to address top-level managers.In facts, Squale and Sonar both: Similarties- analyse code for different languages- get metrics from code and store them into a database- display...
