3. Introduction
HRH Prince Mohammad bin Fahd bin Abdul-Aziz took the initiative in 2002 to help establish a University in the Eastern Province with unique characteristics and distinctive mission/vision statements.
The PMU management awarded the system design project (Academic/Administrative) to one of the top international educational consultants, Texas International Education Consortium (TIEC).
It offers Study in the Field of Engineering and Business and Law.

4. A University with such aims and vast fields of study requires a heavy and reliable networking both within the campus and campus to outside community. There are tons of data that are relayed every minute from faculty to students, administration to faculty, students to faculty and administration etc.

5. Problem Statement Problem Statement Regarding Business
Over Secure System
An over secure system is computer system protected through the use of special hardware and software, policies, and practices against data corruption, destruction, interception, loss, or unauthorized access.
The bad implication of over secured system is affecting all university workers specially instructors.

6. Problem Statement Regarding Network
Lack of internet network availability
The importance of internet network is that it has made information available in a quick and easy manner, publicly accessible and within easy reach.
Lack of network availability prevent workers from receiving urgent s immediately.

7. Network Classification
Connection methods
Wireless LAN – A wireless network is technology that allows two or more computers, to communicate and send data by uses electromagnetic waves, such as radio signal frequency.

8. Wired technologies
Twisted pair – Twisted pair cable Connecting devices to the server and is divided into types :
Shielded Twisted Pair (STP) is batter thane UTP
Unshielded Twisted Pair (UTP) the most commonly used in local networks.

9. Optical fiber - It can be used as a medium for telecommunication and networking because it is flexible and can be bundled as cables. . It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables.

10. Scale
Local area network (LAN) –
Our Organization uses LANs tend to be designed for internal use by an organization's internal systems and employees in individual physical locations. Local area networks (LANS) - is allowing the interconnection and intercommunication of a group of computers, primarily for the sharing of resources and exchange of information.

11. Network architecture
Peer-to-peer
The university uses distributed hash table indexing, such as in the Chord system. In Unstructured peer-to-peer networks they do not provide any algorithm for organization or optimization of network connections.
A peer-to-peer network allows two or more PCs to pool their resources together.
Individual resources like disk drives, CD-ROM drives, and even printers are transformed into shared, collective resources that are accessible from every PC. 
Because peer-to-peer PCs have their own hard disk drives that are accessible by all computers, each PC acts as both a client (information requestor) and a server (information provider).

12. Network topology
Bus network - Bus topology uses a common backbone to connect all the network devices in a network in a linear shape. A single cable functions as the shared communication medium for all the devices attached with this cable with an interface connector. .

13. Star network - In the computer networking world the most commonly used type in LAN is the star topology. Star topologies can be implemented in home, offices or even in a building. All the computers in the star topologies are connected to central devices like hubs, switches or routers

14. Types of Network Based on Physical Scope:
Local Area Network:
Our organization uses LANs which are tend to be designed for internal use by an organization's internal systems and employees in individual physical locations.
Local area networks (LAN) – is defined as allowing the interconnection and communication of a group of computers, in order to share resources and exchange information.

15. 2. Campus Area Network:
Our organization also uses Campus Area Network (CAN). Which is a computer network that connects a few local area networks (LANs) and this kind of network is mostly used in large universities or local business offices and buildings.
A campus area network is considered larger than a local area network but smaller than a metropolitan area network (MAN) or wide area network (WAN).
