A programmer and Founder of Girfa IT Services, working from 2009.At Starting computer teaching was my full-time job but after 10 years of teaching I chose to programming as a full-time job and teaching become part-time. In real life, I am very lazy and I made it my coding style I always try to make a reusable component that’s my USP for programming which saves my time and extra working both.

Passing Array to Java Script Function

You can an array to JavaScript function as an argument. In side of function you can handle this argument in any other programming language. Take a look on following example :

<html>

<head>

<title>Array to Java Script Function : Girfa</title>

function ardemo(ar)

{

for(i=0;i<ar.length;i++)

document.write("[" +ar[i] + "] ");

}

</script>

A9-R4: DATA COMMUNICATION AND NETWORK TECHNOLOGIES

Objective of the Course

This course will allow students to develop background knowledge as well as core expertise in data communication and networking (DCN) technologies, which is one of the fastest growing industries in today’s world. It forms an integral part of the modern Information and Communications Technology (ICT) in any organizations. Starting from intranet/extranet in small offices to the World Wide Web, principles of DCN play an important role in designing any modern telecom infrastructure.

A major ramification of the fantastic growth of telecommunications and networking is a dramatic increase in the number of professions, where an understanding of DCN is essential for success. Today, students wanting to understand the concepts and mechanisms underlying DCN infrastructures come from a variety of academic and professional backgrounds. Hence, to be useful, a course on DCN infrastructures must be accessible to students without technical backgrounds while still providing technical material comprehensive enough to challenge more experienced readers. This course is designed with this new mix of students in mind.
