Network Topologie

QuestionAnswer
A WHAT? is a visual representation of a computer or telecommunications network. It shows the components that make up a network and how they interact, including routers, devices, hubs, firewalls, etc. network diagram
What? l network diagrams describes the way information flows through a network and shows subnets (including VLAN IDs, masks, and addresses) and routing protocols. Logical
WHAT? of a network refers to the way the network is connected and how it communicates. Topology
WHAT? topology refers to the physical interconnection of network devices. Physical
This physical topology is distinguished for having all of the nodes connected by a central medium which has exactly two endpoints. Bus
This physical topology consists of a central hub or switch, through which all of the data passes, along with all of the peripheral nodes connected to that central node Star
In this physical topology, the nodes are only connected to the nodes they interact with most. Partial Mesh
This physical topology is comprised of groups of star-configured workstations, called segments, connected to a linear bus /backbone Bus
This topology is bound to network protocols Logical
WHAT? t is the best known example of a logical bus topology and is associated with physical bus, star, and tree topologies. Ethernet
Explain what the CSMA/CD protocol is and how it works CS= Carrier Sense MA = Multiple Access CD = Collision Detection All computers on the network check the cable for traffic before attempting to transmit a frame of data. Data is sent only if the station doesn't "sense" any data being sent by other devices.
IP addresses and subnets are laid out in WHAT? diagrams. Logical
A WHAT? network diagram shows the actual physical arrangement of the components that make up the network, including cables and hardware. physical
Cabling types and distance, connectors and physical ports are found on a WHAT? network diagram. physical
WHAT? diagrams are a network representation of a system and are the cornerstone for structured systems analysis and design Data flow
Which data flow diagram symbol represents sources or destinations outside the specified system boundary? External entities
. Which data flow diagram symbol represents data repositories for data that is not moving? Data stores
Which data flow diagram symbol represents movement of data in the system? Data Flows
Which data flow diagram symbol represents transforms of incoming data flow(s) to outgoing data flow(s)? Processes
What is the function of data flow diagrams? Illustrate data sources, destinations, flows, stores, and transformations.
The process of representing different detail levels on a data flow diagram is called WHAT? or WHAT Leveling or Partitioning
