1. Exploring the Functions of Networking Flashcards
Define Internet
A global network that interconnects many networks
What is the World Wide Web
A service that relies on connections provided by the internet for its function.
Define LAN
Local Area Network
Define WAN
Wide Area Network
Define SOHO
Small Office, Home Office
Define WLC
Wireless LAN Controllers
What does a WLC do?
Centralizes the management of wireless deployments.
What are Endpoints?
End-User devices such as PCs Laptops, Tablets, etc.
What are Intermediary Devices?
Devices that interconnect Endpoints or interconnect networks. i.e. switches, routers, APs, firewalls, etc.
Define APs
Access Points. They allow wireless devices to connect to a wired network.
Define IPS
Intrusion Protection System - A system that performs a deep analysis of network traffic while searching for signs of suspicious or malicious behavior.
Define WLAN
Wireless Local Area Network.
General term for the physical elements that connect network devices.
Media
Term for the arrangement of a network’s elements
Topology
A measurement of the data rate of a given link in the network. Measured in bits per second. (Two Terms)
Bitrate and/or Bandwidth
Term for how much time a network is accessible and operational
Availability
Term for the ability of a network to operate without failures for a specified time period
Reliability
Formula for the Availability of a Network
Availability = uptime / (uptime + downtime)
[Expressed as a Percentage]
Formula for the Reliability of a Network
Reliability = time in service / number of failures
[Expressed in a unit of time like 55 minutes]
Define Scalability
How easily a network can accommodate more users and data transmission requirements
Define Security
How well the network is defended from potential threats.
Define QoS
Quality of Service
Define Quality of Service
Includes tools, mechanisms, and architectures, which allow you to control how and when applications use network resources.
Define Virtualization
A software solution that emulates network services and functions.
Define Bus Topology
A topology in which every node is connected to a common transmission medium.
Define Ring Topology
A topology in which nodes are cabled in succession, and the last device is connected to the first one to form a circle.
Define Star Topology
A topology in which there is a central device to which all other network devices connect via point-to-point links.
Define Mesh Topology
A topology in which a device can be connected to more than one other device.
What is the Logical Topology of a Network?
The path which data travels from one point in the network to another.
