Active Directory : How Objects Are Stored and Identified
Data stored in Active Directory is presented to the user in a hierarchical fashion. There are two types of objects: containers and non-containers. The most common type of container in Active Directory is an OU (Organizational Unit). Non-container objects are also known as leaf nodes. More ...
IPv4 Address Classes
Originally, IP network numbers were defined with rigid boundaries and grouped into address classes. Even though address classes was created to facilitate efficient use of the IPv4 address space, because of its rigidity it has been abandoned for more flexible classless addressing. More ...
Shortest Path Bridging (SPB) Protocol
Shortest Path Bridging (SPB) protocol is a computer networking technology intended to simplify the creation and configuration of networks, while enabling multipath routing. It is the replacement for the older spanning tree protocols. More ...
Network Operating Systems
The purpose of a network is to permit users share resources located on other computers and to share peripheral devices such as printers. A network operating system (NOS) is specialized systems software designed to provide networking functionality. More ...
IP Addressing and Subnetting
Today, many different kinds of devices can communicate on a network. A network device might be a computer, a router, a printer, or any number of unusual devices. Every device on a network that uses the Internet protocol (IP) needs a unique IP address. More ...
