INTRODUCTION
This is started on the 15 March 2011, at IIJT Team Lease. Before going into the details of the training that I did, I will be glad to give an introduction of the department
About Company
IIJT develops and supports high-fidelity evaluation server for predicting network performance.
IIJT has a reputation for top quality service in education,staffing,
Goals & Focus of Company
IIJT believe that for sustainable success of any organization, it is important to establish and nurture relationships with associates. It is the objective of the company to develop enduring relationships with our students.
Team Lease IIJT primary focus is addressing computing/networking needs, which include Windows 98/2000/XP, Windows Server 2000/2003, Mac OS 9, X and Linux installation, configuration, and troubleshooting, as well as Microsoft Office 2000, XP, 2003 and BackOffice application development. We also provide web-site development, Internet configuration, and cabling services.
BASICS
My project is to develop a wide area network. In WAN we can connect the different systems which are far from each other so that they can easily share their data and resources. To establish we first confirm that how many systems are to be used in that network and what type of operating system being used by the systems. So the all systems should work on same operating system like win XP, Linux etc.
By WAN we can also establish a reliable and secure network. So that the authorized system can only access the resources.
So here is a basic introduction before we should proceed to our project:-
What is network
Advantages of network
What is a network?
Network is an interconnection of computers and networking components such as Routers, Hubs, Switches etc. so that they can share resources as well as data with each other and also able to communicate with other.
Advantages of network in an organization
Add a single shared Internet connection and you no longer need multiple modems and Internet accounts.
.Resource sharing such as Printer and File sharing.
. With networking you will be able to communicate to a person seating at a distant location with the help of your computer on the network.
Switches
Switch is a networking device . It is used to connect two or more computers with a LAN . It is an intelligent device . It is a fully unicast and limited broadcast and internally based on star topology . It does not detect the collision domain.
A switch can reduce network traffic by directing message intended for a specific computer directly to that computer.
BENEFITS OF SWITCHED NETWORK
There are several ways that VLANs simplify network management:
• Network adds, moves, and changes are achieved by configuring a port into the appropriate VLAN.
• A group of users needing high security can be put into a VLAN so that no users outside of the VLAN can communicate with them.
• VLANs can enhance network security.
• VLANs increase the number of broadcast domains while decreasing their size.
