These all computers are connected in STAR Topology: In star topology each computer is connected to the central processor which is called as HUB. Hub act a conduilt to send messages. computers (HOST)are connected to the hub through transmission wires. when one computer sends the message to the other computer this message will firstly go to the hub and the hub store this messag and send it to its address computer connected computer make the graph shape therefore the topology named as the star network topology.

Hub:- hub is central processor ,.There are Four floors and each floor has one hub to connect the computers o network this is simple process to connect the computer with the hub through wires this is local area network computers are connected through ethernet cables.

Network Administrator, is a person or a computer which manage the all servers data and monitors the performance speed of each and every computer if any issues occure then its administrator's job to resolve the issue or to make the system working on the network and it is also responsible for the vailability of the system and services.

Design:- (a)

B:- The network is sever based network because network security and storage are managed centrally by four servers.
