CISCO2 – Routing Protocols and Concepts

These flashcards cover key concepts and definitions from the lecture on routing protocols and networking basics.

Normal latency

The time it takes for frames to travel across the network medium and through network devices.

Latency

The delay experienced by a frame or packet traveling from the source station to the final destination.

Layer 2 devices

Devices that are more intelligent than Layer 1 devices, such as bridges and switches.

Bridge

A Layer 2 device used to divide or segment a network.

Switch

A Layer 2 device also referred to as a multi-port bridge, creating virtual circuits between devices.

Router

A Layer 3 device used to direct traffic between different networks.

Ethernet

A networking technology that uses CSMA/CD and can support fast transmission rates.

BNC

A type of coaxial cable connector used in networking.

NIC

Network Interface Card

PING

A network diagnostic tool used to test connectivity between devices.

LAN

Local Area Network, a network that covers a small geographic area.

WAN

Wide Area Network, a telecommunications network that extends over a large geographic area.

UTP

Unshielded Twisted Pair, a type of cabling used in networking.

DTE

Data Terminal Equipment, the end device that receives or generates data.

DCE

Data Circuit-terminating Equipment, the device that facilitates a connection between DTE devices.

User exec mode

A limited access mode in which basic commands can be executed on a router.

Privileged exec mode

A higher access mode that allows for more advanced commands and configurations.

Memory components of a router

Includes ROM, RAM, and NVRAM, which retain contents when power is absent.
