What is a Ring Topology Network? - RESOLUTION RESULT VERIFIED ANSWERS--A
network setup where devices are connected in a circular or ring-like fashion, with each device
connecting to exactly two others.
Downsides:
-If one device or cable fails, the entire network can be disrupted.
-Data needs to pass through multiple nodes to reach its destination making it slower than star
networks.
-Not suited for large networks.
What is a Star Topology Network? - RESOLUTION RESULT VERIFIED ANSWERS--A
network setup where each device connects to a central hub or switch. The central hub acts as a
conduit for all data transmission. The resulting structure resembles a star with a hub at the
center.
-EX. A home Wi-Fi network where all devices connect to a central wireless router.
-Easy troubleshooting and only the hub is affected when a device fails instead of the entire
network.
, What is a Bus Topology Network? - RESOLUTION RESULT VERIFIED ANSWERS--A
network setup where all devices are connected to a single cable known as a "bus" or
"backbone". Data is transmitted along this cable and is received by all connected devices,
although only the intended recipient will process it.
Downsides:
-When the main cable is damaged the entire network will go down.
-Potential for exposing sensitive information due to the broadcast to all devices. -Data
collision if multiple devices try to send data simultaneously
What does WAN stand for? - RESOLUTION RESULT VERIFIED ANSWERS-wide area
network, made up of LANs connected over long distances
What does MAN Stand for? - RESOLUTION RESULT VERIFIED ANSWERS-Metropolitan
Area Network. Communications network covering a city or a suburb. Many cellphone systems
are MANs.
What does the latency of a network do? - RESOLUTION RESULT VERIFIED ANSWERS-
Measures the delay before data begins to transfer after an instruction for its transfer is given.
-Ex. Lagging in an online game. Actions take time to register on the server and will be reflected
on your screen.
What is a High-level network application protocol? - RESOLUTION RESULT VERIFIED
ANSWERS-Defines rules for how applications communicate with each other over a network.
Ex.
-HTTP (Hypertext Transfer Protocol)
