Configurations & Network Topogy Flashcards
Process of setting up the policies, controls and data
flows that allow devices and systems to communicate
across a computing network.
Network configuration
It comprises all the physical and virtual hardware and software components in a network and the protocols that dictate how data moves between them
Network configuration
What are the type of network configuration?
Scale & topology
The geographical range of a network’s components and devices
Scale
The physical and logical arrangement of nodes and connections in a network.
Topology
Have a small range—typically under 30 feet—and are meant for peripheral devices used by an individual.
Personal area network (PAN)
Private computer networks that allow specific users to have unrestricted access to the same system connection at a central location, typically within one mile and often inside one building.
Local area network (LANs)
network-aware operating systems on user devices can share
resources and devices (printers and scanners, for example).
LANs
can be linked to local area networks (LANs) and other higher-level network types that use a single device as a gateway (connecting a Bluetooth controller to a gaming console, for instance).
PANs
configurations allow users to move freely around a coverage area without the hassle of transporting or staying connected to ethernet wires.
Wireless local area networks (WLANs)
fixed broadband access that uses radio waves instead of cables
Fixed wireless
portable wireless also called?
Mobile hotspots
enables data transmission by using infrared beams instead of wires
Infrared wireless
provides an encrypted connection that hides data packets while users are connected to a public network (such as the internet)
Virtual private area network (VPN)
tunnel between connected devices, encapsulating and encrypting data as it traverses the network to keep sensitive information (such as IP addresses, browsing history, privileged correspondence and logistics) from being revealed online.
VPNs
known as medium-sized networks—cover more area than LANs but are less extensive than wide area networks
Metropolitan area networks (MANs)
Typically, they comprise multiple LANs linked together by using point-to-point high-capacity backbone technology, which serves as a primary connection pathway between network devices.
MANs
can cover several buildings or entire cities, as is the case with DSL and cable TV networks, which use common local and regional resources to connect devices on the network.
MANs
What is DSL?
Digital subscriber line
can be either point-to-point (where devices send data to each other over a private connection) or packet-switched networks (where data is broken into short messages, or “packets” and sent piecemeal) over shared circuits (can take various paths).
WANs
companies address these priorities. It’s primary objective is to
facilitate large data transfers between different storage devices and between storage devices and the computer network.
Storage area network (SANs)
the geometric representation of the relationship of the links and the linking devices (Nodes) in a Network
Topology
refers to the specific configuration and structure of the connections between the Links and the Nodes. Two or more devices connect to a Link and two or more Links form a _____
Topology
each device is connected to every
other device on the network through a dedicated
point-to-point link.
Mesh Topology
