Introduction to Computing Flashcards
(50 cards)
Links computers for shared resources through the internet.
Computer Networking
The smallest type of network with a limited span interconnects compatible personal devices.
Personal Area Network (PAN)
This is used to interconnect and share computer resources in an establishment such as a corporate building, house, or several buildings in a limited area.
Local Area Network (LAN)
An enterprise network covering multiple buildings in a campus environment, including universities and large organizations.
Campus Area Network (CAN)
This covers multiple city buildings, traffic lights, and parking meters, connecting wirelessly.
Metropolitan Area Network (MAN)
A much larger network covering vast areas, such as cities, provinces, and countries.
Wide Area Network (WAN)
It is a diagram displaying the structure of network devices and services to serve the clients’ connectivity needs.
Network Architecture
Brings users and devices together, such as linking employees in a corporate building.
Access Networks
Links multiple servers with data and applications and make them easily accessible to users.
Networks for data centers
Connects users to programs and services, such as hospita employees connecting to health applications.
Wide-area networks (WANs)
An open standard for every communication system to allow interlinking of different types of networks.
Open Systems Interconnection Model (OSI)
Gives electrical and mechanical connections to the network.
Physical layer
Handles error recovery, flow control, and sequencing of terminals that are either sending or receiving.
Data link layer
Acts as the network controller that receives outgoing messages and combines messages and segments into packets with a header detailing routing information.
Network layer
Liable for end-to-end delivery between devices.
Transport layer
Provides the control functions required to start, manage, and end connections to satisfy user requests.
Session layer
Accepts and structures the messages for an application by converting the message from one code to another.
Presentation layer
It interacts with application programs with communication components such as a web browser and email.
Application layer
Uses cabling and connectors to initiate network connections.
Wired Network
Uses radio signals to initiate network connections.
Wireless Network
Connects devices within a local area network.
LAN Ethernet Cable
Interconnects networking devices but risks the broadcast of data it receives to all devices connected to it.
Hub
Initiates a direct connection from the sender to the destination bypassing the data traffic to ensure data privacy.
Switch
Uses a cable connection to create a broadband network connection from a home network to the internet service provider.
Cable Modem
