Network Admin Handbook

Basics, Subnets, IP Addressing, Hardware and Security Considerations

A network is a lot like a community. Both a network and a community are made up of hosts. In a community, we’re talking about homes and other buildings; in a network, it’s PCs, servers, and other devices. The roads that deliver traffic between these hosts in the network world are generally Ethernet, although they may include other types of cables. Each community host has an address. In a network, each host has an IP address. Traffic intersections are handled by switches and routers.

This example can be carried on and expanded upon, but the point is clear. A properly functional network, just like a community, should be designed properly. A network is only as effective as each of its parts. If just one of these items isn’t fully functional, a bottleneck is created and the entire network is negatively affected.

With that challenge in mind, this e-book provides an overview of how to design an efficient and effective network. Read for tips on network hardware selection, setup, security, and more.
