<<BIND 7%
BIND (Berkeley Internet Name Domain) is the most commonly used DNS server on the Internet, especially on Unix-like systems, where it is a de facto standard. The resolver library included in the BIND distribution provides translations between domain names (used by humans) and Internet addresses (used by machines). This process is called DNS resolution and is linked with applications requiring name service.
<<DNS 31%
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 198.168.0.154. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. The BIND DNS server is a very popular and free DNS server. When setting up a new web site one needs to register a DNS name at a DNS registry. One site can have serveral DNS names, also called server aliases.
<<Perl 7%
Perl is a dynamic programming language created by Larry Wall and first released in 1987. Structurally, Perl is based on the brace-delimited block style of AWK and C, and was widely adopted for its strengths in string processing, and lack of the arbitrary limitations of many scripting languages at the time. Perl has been used since the early days of the Web to write CGI scripts. It is known as one of "the three Ps" (along with Python and PHP), the most popular dynamic languages for writing Web applications (which now also include Ruby). It is also an integral component of the popular LAMP solution stack for web development. Large projects written in Perl include Slash, Bugzilla, TWiki and Movable Type.
<<SLA, Service Level Agreement 31%
Service Level Agreement (SLA) is that part of a service of a dedicated hosting contract where the level of service is formally defined. It records the common understanding about services, priorities, responsibilities, guarantee and possible penalties in the case of violation.Service level agreements rely upon numerous service performance metrics to enable performance measurements.
<<TCP/IP 7%
The Internet protocol suite is the set of communications protocols that implements the protocol stack on which the Internet and many commercial networks run. It is part of the TCP/IP protocol suite, which is named after two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were also the first two networking protocols defined. The Internet protocol suite — like many protocol suites — can be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted. The original TCP/IP reference model consists of 4 layers, but has evolved into a 5-layer model. More details here : http://en.wikipedia.org/wiki/TCP/IP_model .
