Nested Structure

Nested Structure C Language

As you know though structure we can process data record by record that is why structure is called user defined data type. In some specific case you nested structure where a structure is inside of a structure. For example when process a student record with their dob. Take a look on following example.
#include<stdio.h>
#include<conio.h>
#include<string.h>
typedef struct s
{
    int roll;
    char name[10];
    struct d
    {
         int dd,mm,yy;
    }dob;
}student;

Static Variable

Static Variable

A static variable initialize by 0 instead of garbage at the time of declaration. Static variable retain its value in memory till the program is running.

On the other hand auto variable lost its data when function scope pass out . But static variable retain its value whenever  scope get over.

You can trace that how many times a function is being called.

void test()
{
    static int k; /* k will retain its value when function scope goes down */
    printf("\nThis function being called %d times ",++k);
}

Read Only Memory

ROM

ROM is read only Non-Volatile memory written data into it while manufacturing. Data of Rom never get change in its entire life.

Example : BIOS,Firware,Console

PROM

PROM is Non-Volatime memory manufactured blank, a user writes program into it. Ones data written in PROM it never get change. PROM is permanent it retain its data when goes off. you need a special device called a PROM programmer or PROM burner. The process of programming a PROM is sometimes called burning the PROM.

Example : mobile phones, Radio Frequency Identification cards (RFIDs), High Definition Media Interfaces (HDMI), and video game controllers

Switch Case in Python

Python does not support switch case direct but you can implement it by using else-if as in following manner

print "Enter day of the week  number>> "
a=int(raw_input())

if(a==1):

elif(a==2):
    print("Tue")
elif(a==3):
    print("Wed")
elif(a==4):
    print("Thu")
elif(a==5):

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>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Array to Java Script Function : Girfa</title>
<script language="javascript">
     function ardemo(ar)
     {
          
           for(i=0;i<ar.length;i++)
                document.write("[" +ar[i] + "] ");
          
          
     }

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.
