Network-architecture is the types and characteristics of various network devices and components. These are routers, switches, and cables. These are routing protocols, the ISO network model, LAN and WAN network systems. These are small local network operations as well as global systems. Network architecture is dynamic, changing in design and scope. At one time, it was peer-to-peer; now it has VPN's, It was cat-5 Ethernet cable, now it is wireless. It was simple so anyone could be a network administrator; now network administrators are expected to carry multiple certifications from Microsoft, Comptia, and Cisco. The Brighthub Guide to network architecture will provide users with articles, how-to's, and introductions to many of these networking architecture elements.
