Computer Network Analysis And Design Case Study Of Sari Mulia University CBT Lab

Abstract

Computer networks have become a vital element in the digital era, and their topology is the key to the effectiveness of all systems. This research identifies the network topology used by Sari Mulia University, especially in the CBT room. The method used was a semi-structured interview with the resource person: Mr. Fajar (university network administrator). The research results show that Sari Mulia University uses the Star Murning topology. The reason is that the Star Murning topology is easy to implement and scalable, but it has the weakness that if the main cable breaks then the entire network is disrupted. The way to overcome this is by repairing the location of the damage or replacing it with a new cable. The central server is connected to one switch, then distributed to routers throughout the campus. In the lab room. CBT has 2 routers, 6 switches, 110 PC units and end users. This research proves that pure star topology supports network effectiveness and reliability. However, pure star topology also has disadvantages. Therefore, this research suggests using a hybrid topology/combination of star and bus. Hybrid topology is not disturbed if a network is disconnected and is easy to implement. The disadvantages are the high cost and potential slowness of the network system.
