You ten must understand the various network topologies and the various types of networks such as local area networks (LANs) and wide area networks (WANs).Certification II Standard 1.0111 Introduction to NetworksNetworks consist of various components (hardware and software) that connect computers and applications that are either far or near each other. Networks allow users to easily access information, thereby increasing their productivity. This section describes some network components and the basic topology types that connect network components, including computers, together. Common resources shared over a network include data and applications, printers, network storage components (shared disk space), and backup storage components.
