The article is primarily intended for people intending to design or implement a computer network. Various topics covered include network planning, implementation, and security considerations. Wireless networking and IP telephony topics have also been discussed.

Juniper Systems® and Cisco® Routers - A beginner's Guide
Network administration has become a main line of profession after the advent of internet and intranets. Though there are several manufacturers that produce network gear, Cisco and Juniper are two front line producers of networking equipment. Cisco equipment uses IOS whereas Juniper equipment uses Junos operating system. The article discusses and compares both the Operating Systems.

WiMAX: Wireless Broadband
WIMAX is used for accessing wireless broadband Internet over a wide geographical areas. Its counterpart Wi-Fi is limited to an operational radius of a few hundreds of feet whereas WIMAX can operate over several kilometers of radius. The article discusses specifications and advantages of using WIMAX, and compares it with WIFI.
