Laboratory 1 Flashcards
A system software within cisco routers
Cisco Internetworking Operating system
This system provides management responsibilities on transmitting data, which means the flows control of request and acknowledgement and security and protocols configurations .
Cisco Internetworking Operating System
User can interact to configure something by means of two interfaces
IOS (Internetworking Operating System)
The two interfaces in IOS?
GUI and CLI
Serves as a guidline for manufacturers to work when connecting.
OSI (open systems interconnection) Reference Model
All resources used for interaction and application belongs in
Application layer
Compresses data, Translates Data, Encrypts Data for security purposes
Presentation
Controls the dialogues (connections) between computers. It establishes, manages and terminates the connections between the local and remote application.
Session
Transmits data using transmission method
Transport layer
It manages device addressing, tracks the location of devices on a network, and determines the best way to move data, which means that the network layer must transport traffic between devices that aren’t locally attached.
Network layer
network devices that forward data packets between computer networks
Routers
Used to transport user data through the internetwork
Data Packets
used to update neighboring routers about the networks connected to all routers within the internetwork
Route Update Packets
The exit point a data packet will take when destined for a specific network.
Interface
is the distance to the remote network Different routing protocol use different ways of computing this distance
Metric
