No, unless the ring is broken then collision can occur
Non-persistent is deferential, while 1-prisistent is selfish.In non-persistent CSMA if the medium is busy, there will be a random delay for retransmission. This reduces the probability of collisions, but wastes the capacity.In 1-persistent CSMA if the medium is busy, the channel will be sensed until it is idle, then it will transmit immediately. This means that collisions are almost guaranteed to occur.
C. Crosstalk The answer is also False, from the Network + Guide to networks 5th edition.
routing refers to deciding the route of the packet from one system (a computer) to another system (a computer). It involves many intermediate routers and routing table knowledge.forwarding is a rather simple process of passing a packet from one port/interface to another port /interface. It generally involves one of the routers and routers forwarding table informationThat's what they called call forwarding service in telecommunication.
A packet may be lost due to congestion: too many packets are sent, the queue gets full, and eventually the router or switch starts dropping packets. It may also occur due to different failures; including temporary cabling problems, problems in a switch or router, etc.; these in turn can cause temporary problems with the routing information (a "non-converged network"), causing the packets to travel in loops until the TTL runs out, or a router erroneously concluding that a certain address can't be reached. This latter problem might also be caused by a misconfigured router.
STP stand for Spaning Tree Protocol. It's used to avoid the L2 loop in the network. many factor are belong to STP. such as Root Switch, BPDU, Root Port, Forward port, blocking port.
In a network, collisions occur when two or more devices transmit data at the same time on the network, resulting in a data packet being corrupted. When a collision occurs, the devices involved must wait for a random amount of time before retransmitting their data to avoid another collision, which can impact network performance and throughput. Modern networks use techniques like collision detection and avoidance to minimize the occurrence of collisions.

There are 3 collisions that occur when a vehicle hits a solid object; the initial impact, the passenger impact on restraints or parts of the vehicle, passengers suffering internal collisions with organs
Each year, there are about 100,000 collisions in the USA alone. Only less than half of these are fatal collisions.
Many head-on collisions may occur on two lane roads while passing, when there is oncoming traffic.
