The project topic is “network topology of university” . here we connect vthe different colleges each other for shareing the information from one place to another place.for comm unication purpose we use the software /hardware resources for proper comm.purpose. In this project we will provide thesecurity,so that any of data is not lost or corrupted during the communication process between the different college. We will use the server to store the data in common database. Authentication process in our projct will be provided so that no unauthorized personcan access the information from any end. All the employees and students are provided their ids and passwords to enter into the system.
A network is a system that transmits any combination of voice, video and/or data between users. A network can be defined by its geographical dimensions and by which the user’s PC access it.
When two or more networks are connect so that they are balk to communicate and share resources with each other. It is called a network. Networking is a practice of linking of two or more computing devices such asPCs, printers, faxes etc., with each other Connection between two devices is through physical media or logical media to share information, data and resources. Networks are made with there hardware and software Introduction ofFIREWALL As the limits of networking is increasing unfolded so the danger of information leaking in and leaking out increases. So a mechanism is required to keep good bits in and bad bits out. And for this we use FIREWALL. A firewall is a device of some kind that separates and protects our network - in most cases, from the Internet. It restricts traffic to only what is acceptable, and monitors that what is happening. Every firewall has at least two network interfaces, one for the network it is intended to protect, and one for the network it is exposed to. A firewall sits at the junction point or gateway between the two networks, usually a private network and a public network such as the Internet. It may be a hardware device or a software program running on a secure host computer. Hardware device means a physical devise connected at the gateway which checks every incoming or outgoing packet. Software program means that software is loaded in computer that determines as what to allow and what to reject
