- 1NOSnetwork operating system
- 2segmentsubdivisions of a network nodes on a common portion connection.
easier for managing purposes - 3back bonetransmission of
data
small segments connect to the backbone - 4serialdaisy chaining
a series of router and switches in a chain that connect to the host - 5Distributeda series of hubs with a central device that is connected to other switches.
easily scaleable - 6Collapsible backboneone central hub /router is connected to individual switches
- 7parallelsimilar to the collapse back bone server however it has two routers and double cabling
bad: adds double wiring slowing down the transmission of data - 8DHCPHost Computer Protocol: computer ip can attach by static or using dhcp to automatically receive an ip address
- 9LansLocal area network: self contained network(room or a building etc.)
- 10WanWide Area Network(multiple locations) its comprised of LAN segments with long range equipment ex(siast)
- 11ICSIndustrial Controll sysytem
- 12SCADSupervisory Control And Data Acquisitions
- 13DCSdistributed Control System
- 14PLC'SProgrammable logical Controllers
- 157-Application of the osi modelenables applications on the networks nodes
prtocols: HTTP, FTP, SMTP, IMAP
PROXIES AND FREWALLS WORK AT THIS LAYER - 166- Presentation layerTransfers application layer data int o an intermediate form that both client nad server can process.
functions: character sets, multimedia formats, MIME, ENCRYPTION
PROXIES AND FREWALLS WORK AT THIS LAYER - 175- Session layerestablishes and controlls data communication between applications operating on two different
protocol: TCP AND UPD port numbers exist at this later
PROXIES AND FiREWALLS WORK AT THIS LAYER - 184-Transport Layerperforms the establishment, maintenance and tearsdown of the connection.
TCP AND UPD protocols exist at this layer
packet filtering, routers multilayer switches and FiREWALLS WORK AT THIS LAYER - 193-Network LayerAdds logical addressing(network addressing) and chooses the best route. IP, ICMP, IGMP exist at this layer.
router, multilayer switches, and firewalls work at this layer - 202- Data Link LayerStructures the data into a format appropriate for the transmission medium. adds physical address(like MAC) adresses or frame relay DLCI
WAN, LAN protocols exist
ethernet, token ring, frame relay, PPP, HDLC, wireless access protocols, ATM and X.25.
switches and bridges work at this layer - 211- Physical Layertransmits bits from one device to another and regualates the transmission stream over a medium.
all electrical and mechanic aspect of data transmission exists at this layer
cabling, connectors, antennas, transeivers, baseband, broadband, signaling types, etc. - 22IEEE stabdardThe Institute of Electrical and Electronics Engineers
standards in a broad range of: power and energy, biomedical and health care, information technology and robotics, - 23poEIEEE 802.3af
transfers electrical poer over a cat 5 or higher
up to 15.4W - 24poE+IEEE 802.3at
BACKWARDS COMPATIBLE W802.3af
25.5W
