What is Mobile Application? Mobile application refers to programs that run on mobile devices, such as Smartphones or tablet Computers. There are lots of application in market falling under different working conditions and lifestyle. In today's world there seems to be an App for everything. It could be a Nursery poem App for your kids, chatting with friends via social networking or checking up on breaking news. There’s an App out there to help you. Most of the Applications work alone, but some of cooperate with tools in other media. For example, If you are playing any game over a Smartphones, the score which you get is only your own score. There is no comparison with the outer world. But some of the games app sync data using the Internet and provide you rank on a particular score. Similarly, some of apps used to connect with the satellite and provide you a live TV facility on Smartphones. Types of Mobile

E-Commerce I:  Period of explosive growth in e-commerce beginning in 1995 & ending in 2000 Vision & Forces behind  E-commerce I:1995-2000 1.  Internet -> PC -> LAN 2.  Start of Bertrand market where price,cost,quality of information is equally distributed where infinite set of suppliers compete against one another.  Merchant have direct access to all relevant market information world wide 3.  Use of Shopping Bot: Program automatically searches entire web for best prices and delivery times. 4. Cost of searching customer fall -reducing wastage of advertisement. 5. Reducing information asymmetry 6. Dis-inter mediation: Disappearance of  market middle man [Distribution ,whole seller who are intermediates] "Displacement of market middle man who traditionally are intermediaries between producers and consumers by a new direct relationship between manufacturers and content originators with their customers. Essential Features 1.  Friction- Free

Electronic Markets An electornic market can be describewd as the use of information and communication technology to present a range of offerings available in a particular market segment. This helps the purchaser to compare prices abd other attributes such as discount ,quality and take actions. e.g.     Railway booking , bookmyshow etc.. Electronic Data Interchange :Electronic data interchange implies a standard system that can be used for coding trade transactions and communicating direclty from one computer to the other.  In such system there is no need of paper work such as bills/invocies and thus eliminates many human errors. The major sector where EDI is being used is Large super market chains E-Commerce Buying and selling goods online is the prime model of e-commerce. E-commerce can be applied to different phases of trade cycle.  This trade cycle will depend on  factors like 1. Nature of organisations (or individuals) who are involved in e-commerce

Program code in C for M/M/1 queuing model #include<stdio.h> #include<conio.h> void main() { int lam,mu,n,i; float l,lq,ls,wq,ws,rho,p[20]; clrscr(); printf("\nEnter value for lam="); scanf("%d",&lam); printf("\nEnter value for mu="); scanf("%d",&mu); printf("\nEnter value for n="); scanf("%d",&n); l=(float)lam/(lam-mu); ws=(float)(lam/mu); wq=(float)(ws-(1/mu)); lq=(float)(pow(mu,2)/((mu)*(mu-lam))); rho=(float)lam/mu; p[0]=(float)(1-(lam/mu)); for(i=1;i<n;i++) p[i]=(float)(p[0]*(pow(rho,i))); printf("\n\n\nThe calculated results are=\n"); printf("\n l=%f",l); printf("\n ws=%f",ws); printf("\n wq=%f",wq); printf("\n lq=%f",lq); printf("\n p=%f",p); printf("\nThe probablities are!!\n"); for(i=0;i<n;i++) printf("\np[%d]=\t%f",i,p[i]); getch(); } by A

Hi   All Its a very good simulator   for M/M/1. It brings t he power of Discrete Event Simulation and Web technologies for teaching and learning Queuing Theory and Queuing Networks.     Complex networks of M/M/1 queues can be modeled and simulated easily with this web-based simulator. The simulator runs a complete discrete event simulation to generate the statistics of queues and systems. http://www.simjs.com/queuing/

FEL is Future event list. A list of event notices for future events. The event notice must contain all the information necessary to execute the event (in particular the time it is scheduled to occur).  The event list is the main data structure in a  discrete-event simulator  so its important to code for FEL. #include<stdio.h> #include<conio.h> /*****************************FEL for a grocery shop!!**********************************/ //Defining structure for customer!! typedef struct { int cno,inter_arr,arr_time,ser_time,beg_time,wait_time,end_time,sys_time,idle_time; }cust; //Defining structure for FEL because we have entries for arrival,departure,end & their respective time!! typedef struct { char ename; int time; }event; //For lookup function for inter-arrival time!! int lookup_interarr(int i) { if(i>=0 && i<13) return 1; else if(i>=13 && i<25) return 2; else if(i>=25 &&
