functions as a bridge, which can connect two (local area networks) LANs
together or segment a large one into two smaller ones.
Multilayer Switch A switch that uses a combination of switching and routing.
A multilayer switch (also called a Layer 3 switch) works by utilizing switching
tables and switching algorithms to determine how to send data through MAC
addressing from host-to-host or device-to-device.
Network Device Interface Specification (NDIS) The layer of Microsoft’s Windows
model that maps to the data link layer of the OSI model and the network
interface layer of the Defense Advanced Research Projects Agency (DARPA)
model.
Network Attached Storage (NAS) Devices that are dedicated to providing storage
of data on the network. NAS uses hard disks for storage, but instead of
being installed on a server, the storage device is accessed through its own
network address.
Network Adapter A device that allows computers to transmit and receive data

packets to the unauthorized device. This is also called spoofing.
Network Model Determines the levels of security that are available to the
network and the components needed to connect the computers together.
Network Monitor A tool that monitors traffic on the network and displays the
packets that have been transmitted across the network.
Network Operating Systems (NOS) Softwares such as Windows, NetWare, or
Linux that may be used for a server, which is a computer that provides services
to numerous computers, and/or installed on computers that are used
by individual users of the network.
Network Type Defines the size of the network and its scale within a geographical
area.
Open Systems Interconnection (OSI) Model A seven-layered framework used
as the model for distributed communications that was formed by the
International Organization for Standardization in 1977.
