Repeaters

Repeaters are also called Re-generator.

Repeaters is only hardware device.

Repeaters re-generate the original bit pattern.

 Figure: Repeaters in Computer Network

The purpose of repeater is to extend the LAN segment beyond its physical limits.

Open System Interconnection (OSI) Model

The OSI stand for "Open System Interconnection".

It was first introduced in the late 1970s by the ISO (International Standard Organization).

An OSI is a set of protocol that allow any two different system to communicate regardless of their underlying architecture.

The OSI model is not a protocol; it is a model for understanding and designing a network architecture that is flexible, robust, and inter-operable.

It consists of seven separate but related layers, each of which defines a part of the process of moving information across network.

These seven layers of OSI model can be divided into two categories:

Gateway

Q. What is Gateway?

A gateway is hardware & software devices

Gateway is used to interconnect LAN & WAN.

 Figure: Gateway in Networking

Gateway makes communication possible between different architecture & environment.

Gateway perform protocol and date onversion.

A gateway operate at the "Transport Layer" and above.

Routers

Question: What is routers?

A router is a special purpose computer, that allows to connect to multiple computer networks.

Routers are both hardware & software devices.

 Figure: Routers in computer networking

Router can connect network segments, and filters and isolate traffic.

Bridge

A bridge segment or divide a network to isolate traffic related problem.

A bridge sends the data frames only to the concerned segment.

Bridges are used to connect dis-similar network like ethernet system to Token Ring-System. Thus bridge used to join network using CSMA/CD access and token passing access.

 Figure: Bridge in Networking

Bridge are both hardware and software devices.

Hub

Hubs are also called "Multi port repeaters" or "concentrators".

Hub is hardware devices.

 Figure: Hubs in computer networking

Hub is similar to repeaters, except that it broadcast data received by any port to tall other parts on the hub.

Random Number Pyramid

Q. Write a C program to print the any entered number, digit pyramid,

For example:

if entered number is : 87954
then output must be as:

87954
7954
954
54
4

Ans.

/*c program for random digit pyramid*/
#include<stdio.h>
int main()
{
int n[50],i,j=0,k,r,c,len;
printf("Enter total length of number : ");
scanf("%d", &len);
printf("\nNote: Entered digit MUST be single.\n\n");
for(i=0; i<len; i++)

4

Ans.

/*c program for diamond pattern*/
#include<stdio.h>
