Fundamentals Of Communication And Networking Flashcards
Wifi and it’s purpose
A wireless local area network that is based on international standards
Used to enable devices to connect to a network wirelessly
Components required for wireless networking
Wireless network adapter
Wireless access point
How does disabling the SSID increase security of a network
SSID of the network cannot be seen when trying to connect so only trusted users who knows the SSID of the network can connect
How does MAC address white list increase security of a wireless network
MAC is a unique code that can identify a particular device on a network
Whitelisting means that only certain trusted people on a network can access it
CSMA/CD protocol
To detect collisions and and only starts transmission when the channel is free before a station starts transmission. Ethernet is not required.
Purpose of SSID
allows user to connect to the desired network when multiple independent network operate in the same area
Peer to peer
Doesn’t need a central server and easier to set up
Less secure and speed of one machine can affect other machines in a network
Physical star topology
How nodes are physically laid out
Logical star topology
How data flows through a network
How can a network physically wired in a star topology behave logically as a bus network
By using a bus protocol and appropriate physical switching
Client server networking
Faster access speed and more secure
Client is dependant on the server
Baud rate
Number of signal changes in the medium in a second
Bandwidth
Range of frequencies that can be transmitted across a network connection
Protocol
Set of rules
Bit rate
Number of bits transferred between devices in one second
