Network architecture is the way network are designed to communicate.
TYPES OF ARCHITECTURE
 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 cetralized control over network resources.
 a network in which one or more computers act as a server, and other computers (clients) on the network request services from the server.
ADVANTAGES
 1) Less startup cost to setup the network architecture-no need for a server
2) Easy to install and configure for the computers in the network
3) When a peer fails it will not not affect other peers to the network is reliable
 1) Cetralized- resources and data security are controlled through the server.
2) Scalability- adding or removing resources in the network can be easily done by configuring the server,
3) Better management of files- all files are stored in the server.
3) Accessibility- server can accesses remotely and across multiple platforms Windows, Linus, and Mac OS.
DISADVANTAGES
 1) Decentralized- no central repository for files and application
2) Less security- does not provide the security available on a client/server network.
3) Every user is taking care is his/her own machine
 1) Expense- requires initial investment in dedicated server.
2) Maintainance- large networks will require a staff to ensure efficient operation.
3) Dependence- when server goes down, opersations will cease across the network.
