01-01 Networking Today - Terms Flashcards
any computer connected to a network that participates in network communication
host
computers with software that allows them to provide information to other many other devices on a network
servers
computers that have software for requesting and displaying the information provided by servers
clients
computers with software for requesting and displaying the information provided by servers
clients
a network in which member devices work as both clients and servers
peer-to-peer network
What are four advantages of peer-to-peer networks?
- Easy to set up
- Less complex
- Lower cost
- Used for simple tasks
What are four disadvantages of peer-to-peer networks?
- no centralized administration
- not as secure
- not scalable
- don’t perform as well
devices that are either the <i>source</i> or the <i>destination</i> of a transmitted message
end devices
devices that connect individual end devices to a network
intermediary devices
List three of the main functions of intermediary devices
- regenerate/retransmit communication signals
- maintain information about available pathways
- notify other devices about errors or comms failures
- direct data along alternate pathways when links fail
- classify and direct messages according to priority
- permit/deny the flow of data, based on security settings
physically connects an end device to a network
network interface card
a connector or outlet on a networking device where a medium connects to an end device or another networking device
physical port
a specialized port on a networking device the connects to a network
interface
a type of topology diagram that illustrates the physical locations of intermediary devices and cable illustrations
physical topology
a type of topology diagram that illustrates the devices, ports, and addressing scheme of a network; describes which end devices are plugged into which intermediary devices and the media being used
logical topology
a type of network capable of carrying multiple services, voice, data, and video, over one network
converged network
List four characteristics of network reliability
- fault tolerance
- scalability
- QoS
- security
a network that limits the number of devices affected by a failure is said to be <BLANK></BLANK>
fault-tolerant
this condition occurs when the demand for bandwidth exceeds the amount available
congestion
the primary mechanism for managing congestion and ensuring reliable delivery of content to all users
QoS
Identify the class of cloud:
“Intended for a single entity, such as a government. Can be set up using the organization’s private network, although this can be expensive to build and maintain. Can be managed by an outside entity with strict access security.”
private cloud
Identify the class of cloud:
“Applications and services within this cloud type are made available to the general population. Service may be free or pay-per-use. Uses the internet to provide services.”
public cloud
Identify the class of cloud:
“Made up of two or more clouds, where each part remains a distinct object, but the parts are connected using a single architecture. Individual users have degrees of access to various services based on user access rights.”
hybrid cloud
Identify the class of cloud:
“Created for exclusive use by specific entities or organizations. Functional needs are customized for a group of users. Used by multiple organizations that have similar needs and concerns.”
community cloud
