GPS (Global Positioning System)

You might have heard this word many times . . . But do you know what actually it is?

Also known as NAVSTAR provides you the information about your position where you are on the earth. The whole system is depended on satellites, which continuously sends the radio signals to a device that can receive these signals. To use this system you must attain the GPS receiver such as MapyIndia or any other device which is suitable for it. 

Satellites are spaced on geosynchronous orbit in such a way that it moves around the earth nearly 12,000 miles twice a day.  You might be thinking how it works? . . . The mechanism abaft it is, that all the satellites are managed by monitoring system which is situated on the earth, and it continuously uploads the data to the satellites, to provide the services to the users. Each satellite has an internal clock that executes at every tick event and sends the stipulated data to the user's device. The same type of internal clock is also available on user's device which doesn't sends any data to the satellite, but receives and matches the coded signal sent by satellite. If the signal matches then the computed data is displayed on the screen.

The working principle of the system is dependent on naive mathematics. When three satellites out of 28 intercepts, the point generated is the location of the user.

I request you to quest more on this topic and you can tell me if you find any confusion . . . Thank you

Characteristics of a Good Programming Language

Till now there are many high level languages which are very popular, and there are others, which could not become so popular in-spite of being very powerful. There might be many reasons for the success of a language, but one obvious reason is the characteristics of the language. Several characteristics believed to be important with respect to making a programming language good are briefly discussed below. Simplicity A good programming language must be simple and easy to learn and use. For example, BASIC is liked by many programmers only because of its simplicity. Thus, a good programming language should provide a programmer with a clear, simple and unified set of concepts which can be easily grasped. It is also easy to develop and implement a compiler or an interpreter for a programming language that is simple. However, the power needed for the language should not be sacrificed for simplicity. The overall simplicity of a programming language strongly affects the readability of the pr...

Angular 4 and Firebase Authentication: Setup

If you have come to this article, it means you are keen to learn new technology and that too Firebase. I love Firebase because it provides all basic but important features of any web application. Take for example, authentication, which is cumbersome and risky if not implemented with utmost care. And when we have the integration of Angular and Firebase, it becomes a lot easier for a developer to build such crucial modules in less time with minimal efforts. In this article we will create a simple Angular application using Firebase. I am going ahead with the understanding that you know the benefits of Firebase and have little knowledge about it. There are plenty of posts out on the web if you are behind. Step 1: Install Angular CLI (if not installed). npm install -g angular-cli Step 2: Create new Angular 4 project. By default now angular CLI will create Angular 4 project so you need not fret. ng new firebase-authentication Step 3: Check whether the ne...

Switch-case, simple calculator . . .

11.      Write a program to perform some mathematic functions with the help of “switch-case” statement. #include<stdio.h> #include<conio.h> void main() { int a,b,ans; char c; clrscr(); printf("\ Enter a and b:"); scanf("%d%d",&a,&b); printf("\n Enter operator:"); fflush(stdin); scanf("%c",&c); switch(c) { case'+':ans=a+b;       break; case'-':ans=a-b;       break; case'*':ans=a*b;       break; case'/':ans=a/b;       break; } printf("\n ans %d",ans); getch(); } 12.      Print the Fibonacci series #include<stdio.h> #include<conio.h> void main() { int a=1,b=1,s=3,c,ch; clrscr(); printf("how many steps="); scanf("%d",&ch); printf("%5d%5d",a,b); for(s=3;s<=ch;s++) {       c=a+b;       printf("%5d",c);       a=b;    ...
