| TYPES OF ARCHITECTURES | PEER TO PEER | CLIENT-SERVER |
| DIAGRAM |  |  |
| DEFINITION | A NETWORK MODEL IN WHICH ALL COMPUTERS CAN FUNCTION AS CLIENTS OR SERVERS AS NEEDED, AND THERE'S NO CENTRALIZED CONTROL OVER NETWORK RESOURCES | NETWORK IN WHICH ONE OR MORE COMPUTERS ACT AS A SERVER AND THE OTHER COMPUTERS(CLIENTS) ON THE NETWORK REQUEST SERVICES FROM THE SERVER |
| ADVANTAGES | -EASY TO INSTALL AND CONFIGURE FOR THE COMPUTERS IN THE NETWORK -WHEN A PEER FAILS IT WILL NOT AFFECT OTHER PEERS SO THE NETWORK IS RELIABLE | -CENTRALIZED. RESOURCES AND DATA SECURITY ARE CONTROLLED THROUGH THE SERVER -BETTER MANAGEMENT OF FILES |
| DISADVANTAGES | -LESS SECURITY -EVERY USERS IS TAKING CARE HIS/HER OWN MACHINE | -EXPENSE. REQUIRES INITIAL INVESTMENT IN DEDICATED SERVER -MAINTENANCE. LARGE NETWORKS WILL REQUIRE A STAFF TO ENSURE EFFICIENT OPERATION |
| CLIENT/SERVER | PEER TO PEER |
| SOFTWARE INSTALLATION IN THE SERVER ONLY | SOFTWARE INSTALLATION FOR ALL COMPUTERS |
| HIGHER CABLING COST | LESS CABLING COST |
| SECURITY CONTROL BY SERVER(CENTRALIZED) | SECURITY CONTROL BY THEIR OWN |
