Difference between non-persistent and p-persistent csma?
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.
Does latency occur when a signal traveling on one wire or cable infringes on the signal traveling over an adjacent wire or cable?
C. Crosstalk The answer is also False, from the Network + Guide to networks 5th edition.
What is the difference between routing and forwarding?
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.
What are the two types of interactions?
The two types of interactions are direct and indirect interactions. Direct interactions occur when individuals or entities engage with one another face-to-face or through immediate communication, such as conversations or physical actions. Indirect interactions involve influence or effects that occur through intermediary factors, such as social networks or environmental changes, where the connection is not immediately visible. Both types play crucial roles in shaping relationships and dynamics within various contexts.
What is packet loss in networking?
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.
Where do packet collisions never occur?
Packet collisions never occur in switched networks, particularly when using full-duplex Ethernet. In full-duplex mode, devices can send and receive data simultaneously on separate channels, eliminating the possibility of collisions. Additionally, in point-to-point connections, where there is a dedicated link between two devices, packet collisions also do not occur.
What happens when collision occur in anetwork?
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.
What time do most fatigue - related collisions occur?
most fatique related collisions occur between 3 and 5 am
What time do most fatigue-related collisions occur?
most fatique related collisions occur between 3 and 5 am
How many auto collisions occur?
a lot
Do collisions occur in full duplex?
A collision will never occur in full duplex.
What is the portion of a network in which collisions occur?
collision domain
Where do most fatal collisions occur?
In rural Areas
How million collisions occur each year?
3million
How many collisions occur when a vehicle hits a solid object?
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 over how many collisions occur?
Each year, there are about 100,000 collisions in the USA alone. Only less than half of these are fatal collisions.
Why does Many head-on collisions occur on two-lane roads when passing?
Many head-on collisions may occur on two lane roads while passing, when there is oncoming traffic.
