only have 1/2 of an inch of 'untwisted' wire at the end; otherwise it will be 'out of spec'. At this

point, you obviously have ALOT more than 1/2 of an inch of un-twisted wire.

3. You have 2 end jacks, which must be installed on your cable. If you are using a pre-made

cable, with one of the ends whacked off, you only have one end to install - the crossed over end.

Below are two diagrams, which show how you need to arrange the cables for each type of cableend.

The codes are commonly depicted with RJ-45 jacks as follows (the view is from the front of thejacks)

Diagram shows you how to prepare Cross wired connection

Purpose of Crossover Cable-

Crossover cables are very similar to straight-through cables, except that they have pairs of wires

that crisscross. This allows for two devices to communicate at the same time. Unlike straightthrough cables, we use crossover cables to connect like devices.

Crossover cables are typically used in the following situations:

Use a crossover cable when:

1. Connecting a computer to a router

2. Connecting a computer to a computer

3. Connecting a router to a router

4. Connecting a switch to a switch

5. Connecting a hub to a hub

Diagram shows you how to prepare straight through wired connection

Purpose of Straight through Cable-

Straight-through cables get their name from how they are made. Out of the 8 pins that exist on

both ends of an Ethernet cable, each pin connects to the same pin on the opposite side.

A straight-through cable is typically used in the following situations:

Use a straight-through cable when:

1. Connecting a router to a hub

2. Connecting a computer to a switch

3. Connecting a LAN port to a switch, hub, or computer

Experiment2

Aim: Write a program to implement bit stuffing & Destuffing

Resources: Turbo C, C++.

Theory:

Bit Stuffing and DestuffingInclude ,, files both in transmitter & receiver

programs.

During the transmission, attach a flag pattern (01111110) at the start & end ofdata unit.

If transmitter sees five consecutive ones in data, it stuffs zero bit in data.

At the receiving end, whenever in data it finds five consecutive ones and the next

bit are zero then the receiver will de stuff that zero bit.e.g. If the Pattern to be transmitted is 00011110111110000, then at the transmitter side

will be 000111101111100000 because as 5 consecutive 1s are detected, one 0 should be stuffed and at the receiver side again as it will detect 0 after 5 consecutive 1s , it will

destuff it.

Code:

#include

#include

#include

void main()

{

char a[20],b[20];

char flag[8]="01111110",e='0';

int i,j=0;

Experiment 3

Aim: Write a program to implement character stuffing & Destuffing


Theory:

Character Stuffing and DestuffingInclude ,, files both in transmitter & receiver

programs.

This is type of Framing Method.During the transmission attach a ASCII Code pattern DLE STX at the start &

DLE ETX end of data Unit.

If transmitter sees DLE stuff another DLE text in data.

At the receiving end, whenever the data it finds five consecutive DLE thenreceiver will destuff One DLE.

Code:

#include

void main()

{

int i,j=0;

char str[100],str2[100],flag,esc;

clrscr();

printf("\n Enter the data string: ");

Experiment4

Aim: Write a program to implement CRC.


Theory:

It does error checking via polynomial division. In general, a bit stringbn-1bn-2bn-3b2b1b0

As

bn-1Xn-1 + bn-2 Xn-2 + bn-3 Xn-3 + b2 X2 + b1 X1 + b0Ex: -

10010101110

As

X10 + X7 + X5 + X3 + X2 + X1All computations are done in modulo 2

Algorithm:-

1. Given a bit string, append 0S to the end of it (the number of 0s is the same as the degree ofthe generator polynomial) let B(x) be the polynomial corresponding to B.

2. Divide B(x) by some agreed on polynomial G(x) (generator polynomial) and determine

the remainder R(x). This division is to be done using Modulo 2 Division.3. Define T(x) = B(x)R(x)

(T(x)/G(x) => remainder 0)

4. Transmit T, the bit string corresponding to T(x).

5. Let T represent the bit stream the receiver gets and T(x) the associated polynomial. Thereceiver divides T1(x) by G(x). If there is a 0 remainder, the receiver concludes T = T

and no error occurred otherwise, the receiver concludes an error occurred and requires aretransmission.

Code:

#include

#include

#include

void main()

{ char st1[10],st2[15],div[5],q[15],i_ans[5],i_op[5],cw[15];

int l,i,n,m;

clrscr();

printf("\nEnter the string: ");

scanf("%s",st1);

strcpy(div,"10101");

strcpy(st2,st1);

strcat(st2,"000000");

printf("\nDivisor is: %s",div);

printf("\nDividendo is: %s\n",st2);

l=strlen(st2);

Experiment5

Aim: Implementation of parity checker.


Theory:

Parity checking refers to the use ofparitybitsto check thatdatahas been transmitted

accurately. Parity checking is the most basic form oferror detectionin communications.

Two transmitting devicesare communicating witheven parity.As the transmitting device sends

data, it counts the number of set bits in each group of seven bits. If the number of set bits is even,

it sets the parity bit to 0; if the number of set bits is odd, it sets the parity bit to 1.

Every byte has an even number of set bits. On the receiving side, the device checks each byte to

make sure that it has an even number of set bits. If it finds an odd number of set bits, the receiver

knows there was an error during transmission.

Code:

#include

#include

#include

void main()

{ int i=0,j=0;

char msg1[9],msg2[9];

clrscr();

printf("Enter any 9-bits:");

scanf("%s",&msg1);

for(i=0;i

printf("\n Odd Parity");

j=0;

printf("\n \nEnter any 9-bits:");

scanf("%s",&msg2);

for(i=0;i


20/53



Experiment6

Aim: Write a program to implement Hamming code.


Theory:

Hamming code is a set of error-correction code s that can be used to detect and correctbiterrors

that can occur when computer data is moved or stored.

Hamming code is technique developed by R.W. Hamming for error correction. This method

corrects the error by finding the state at which the error has occurred.

Code:

#include

#include

#include

void main()

{

clrscr();

int x1,x2,x3,i,x[4],y[7];

printf("Enter 4-bit data: ");

for(i=0;i


21/53



y[1]=x2%2;

y[3]=x3%2;

printf("\n \n Generated Hamming Code (even parity): ");

for(i=0;i


22/53



Experiment7

Aim: Write a program to find Hamming distance


Theory:

Ininformation theory,the Hamming distance between twostringsof equal length is the number

of positions at which the corresponding symbols are different.

In another way, it measures the minimum number of substitutions required to change one string

into the other, or the minimum number of errors that could have transformed one string into the

other.

Code:

#include

#include

void main()

{

clrscr();

int i,j=0,a[5],b[5];printf("Enter 5-bit data1: ");

for(i=0;i


23/53



printf("Hamming distance: %d",j);

getch();}

Output:

Conclusions:

Experiment8

Aim: Write a C program for IPV4, Implementation of decimal to binary, Implementation of

binary to decimal.


Theory:

Internet Protocol version 4 (IPv4)is the fourth version in the development of theInternet

Protocol (IP)Internet,and routes most traffic on the Internet. However, a successor protocol,

IPv6,has been defined and is in various stages of production deployment. IPv4 is described in

IETFpublicationRFC 791 (September 1981), replacing an earlier definition (RFC 760,January

1980).

IPv4 is a connectionless protocol for use onpacket-switched networks. It operates on abest

effort delivery model; in that it does not guarantee delivery, nor does it assure proper sequencing

or avoidance of duplicate delivery.

Code:

(a) Implementation of IPV-4

Experiment12

Aim: To configure FTP server on windows server.

Resources: Windows 2003 Server, Windows XP Professional Client

Theory:

File Transfer Protocol (FTP) is a standardnetwork protocol used to transfer files from onehostto another host over aTCP-based network, such as theInternet.

FTP is built on aclient-server architecture and uses separate control and data connectionsbetween the client and the server.[1] FTP users may authenticate themselves using aclear-text

sign-in protocol, normally in the form of a username and password, but can connect

anonymously if the server is configured to allow it. For secure transmission that hides (encrypts)

the username and password, and encrypts the content, FTP is oftensecured withSSL/TLS("FTPS")

Procedure:

SETUP IIS Server and host website

IIS (Internet Information Services) is an easy-to-use web server from Microsoft. IIS is not

installed on Windows XP Professional by default. It is however installed when you upgrade fromWindows NT or Windows 2000 to Windows XP Pro. If not installed IIS can be installed as

follows:

1- Start-> control panel-> Add/Remove program->Add/Remove windows component

2- When the Windows Components Wizard appears, click Next. From here select IIS.

The IIS is configured using the IIS snap-in, previously called the Internet Services Manager. Thiscan be accessed in one of three ways:

Method 1:1- From the Start menu, select Settings and then Control Panel2- Open Administrative Tools3- Open Internet Information Services

Method 2:1- Right click on My Computer on your desktop

2- Select Manage to open the Computer Management console
