ANSWERS |ALREADY GRADED A+
What is a Ring Topology Network? - ANSWER--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? - ANSWER--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? - ANSWER--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? - ANSWER-wide area network, made up of LANs connected over
long distances
What does MAN Stand for? - ANSWER-Metropolitan Area Network. Communications network
covering a
city or a suburb. Many cellphone systems are MANs.
What does the latency of a network do? - ANSWER-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? - ANSWER-Defines rules for how
applications communicate with each other over a network.
Ex.
-HTTP (Hypertext Transfer Protocol)
-FTP (File Transfer Protocol)
-Telnet -used for remote terminal connections
-SSH (Secure Shell)
-NFS (network File system)
-DNS (Domain name system)
-SMTP (Simple Mail Transfer Protocol)
