Network Basics Flashcards
What’s the purpose of networks?
The purpose of networks is to make connections between machines (sending data from one place to another)
What are examples of network?
Examples of network are:
smart watch and smart phone
tablet and Wi-Fi access point and internet
desktop and hub and switch and router and internet
(all of them are converged networks)
in olden days -
telephone network - (only making phone calls)
computer networks - (only transferring data over a digital network)
What kind of network traffic can you expect to see within converged networks?
Network traffic you can expect to see within converged networks are:
file sharing video chatting (skype) surfing the web social media streaming videos e-mails instant messages phone calls
a lot of different things and a new types of traffic happening all the time as well because new things are being designed and added to our networks
What comprises our networks?
Networks are comprised of:
client server wireless access point hub switch router WAN Link Media
What is client?
Client is a device used by an end-user to access network (any device that connects to the network)
What is server?
Server is a device that provides resources to the rest of the network (different servers provides different functions i.e. a web server, an email server, a file server, a chat server, a print server)
What is a hub?
A hub is an older technology that connects network devices together (using hubs can lead to increased network errors)
What is WAP?
Wireless access point (WAP) is a device that allows wireless devices to connect into a wired network
What is a switch?
A switch is a device that connects network devices together (like a next generation hub)
What is a router?
A router is a device that connects two different networks together and forwards traffic to and from a network
What is media?
Media connects two devices or a device to a switch port
What is WAN Link?
Wide Area Network (WAN) physically connects two geographically dispersed networks
What is client server model?
Client server model uses a dedicated server to provide access to files, scanners, printers, and other resources
What are benefits of client server model?
Benefits of client server model are:
Centralized administration
Easier management
Better scalability
What are drawbacks of client server model?
Drawbacks of client server model are:
Higher cost
Requires specialized OS
Requires dedicated resources
What is Peer-to-Peer Model?
In Peer-To-Peer Model peers share resources (files/printers) directly with others
What are benefits of Peer-To-Peer Model?
Benefits of Peer-To-Peer Model are:
Lower cost
No dedicated resources
No specialized OS
What are drawbacks of P2P Model?
Drawbacks of Peer-To-Peer Model are:
Decentralised management
Inefficient for large networks
Poor scalability
What is PAN?
Personal Area Network (PAN) is the smallest type of wired or wireless network that covers the least amount of area (i.e. Bluetooth, USB)
What is LAN?
Local Area Network (LAN) connects components within a limited distance
What is the number of Ethernet?
The number of Ethernet is (IEEE 802.3)
What is the number of Wi-Fi?
The number of Wi-Fi is (IEEE 802.11)
What is CAN ?
Campus Area Network (CAN) connects LANs that are building-centric across a university, industrial park, or business park
What is MAN?
Metropolitan Area Network (MAN) connects scattered locations across a city or metro area
