What type of media access control does Ethernet use?
Ethernet uses Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as its media access control method. In this system, devices listen to the network before transmitting data to ensure that the channel is clear. If two devices transmit simultaneously, a collision occurs, and both devices stop transmitting, wait a random period, and then attempt to resend their data. This approach helps to minimize data collisions and manage access to the shared communication medium.
Describe how carrier sense multiple access protocol improves throughput compared to purely random acess protocol?
CSMA tries to determine whether the network is already in use by another system before attempting to transmit (multiple access). It is a contention based technique; devices contend with each other to use the network. So if a device is already transmitting the other device will wait.If devices were to randomly attempt to transmit without listening first there would be more collisions between devices, which would lead to lower throughput of data through the network.
What is the CSMA process used for?
Carrier Sense Multiple Access (CSMA) is a network protocol used to efficiently share a transmission medium among multiple nodes. It helps devices avoid collisions on the network by checking if the channel is busy before transmitting data, reducing the likelihood of data packets interfering with each other.
Why is there data collision in bus network?
Data collision in a bus network occurs when multiple devices attempt to transmit data simultaneously over the same communication channel. Since the bus network shares a single communication line, overlapping signals can interfere with each other, leading to corrupted data. This situation is typically managed by using protocols like Carrier Sense Multiple Access with Collision Detection (CSMA/CD), which helps devices sense the channel's status before transmitting. If a collision is detected, the devices will wait for a random time before attempting to retransmit, minimizing future collisions.
How the Ethernet multiple access rules govern which network node gets precedence with regard to media access?
Ethernet multiple access rules, primarily defined by the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol, govern media access by requiring nodes to listen to the network before transmitting. If the medium is clear, a node can send its data; if two nodes transmit simultaneously, a collision occurs, and both nodes stop transmitting. They then wait a random backoff period before attempting to retransmit, ensuring fair access and reducing the likelihood of repeated collisions. This process allows for efficient use of the network while minimizing delays.
What are the three methods of controlling collisions on a network?
The three methods of controlling collisions on a network are Carrier Sense Multiple Access with Collision Detection (CSMA/CD), which listens for traffic before transmitting; Token Ring, where a token circulates on the network and only the device holding it can transmit; and Time Division Multiple Access (TDMA), which allocates specific time slots for each device to transmit data, preventing collisions altogether. Each method helps manage how devices share the network bandwidth to minimize data loss and maintain efficient communication.
What are the basic operating principles behind csma?
Carrier Sense Multiple Access (CSMA) is a network protocol that helps manage access to a shared communication medium. Its basic operating principles involve "listening" to the channel before transmitting data (carrier sensing) to ensure it is clear. If the channel is busy, the transmitting device waits until it becomes free. Once the channel is clear, the device sends its data, aiming to minimize collisions and improve network efficiency.
What type of switching has a connection established between two network nodes before they begin transmitting data?

What Is An IP Password?
An IP password typically refers to a security measure used to protect access to devices or networks that utilize Internet Protocol (IP) addresses, such as routers, servers, or other network equipment. This password is required to authenticate users before granting them access to the device's configuration settings or network resources. It helps prevent unauthorized access and ensures the integrity and security of the network. Properly managing IP passwords is crucial for maintaining network security.
Does Ethernet uses CSMA CA?
No, Ethernet does not use Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). Instead, Ethernet employs Carrier Sense Multiple Access with Collision Detection (CSMA/CD). In CSMA/CD, devices listen to the network before transmitting and can detect collisions that occur, allowing them to retransmit after a random delay. CSMA/CA is primarily used in wireless networks, such as Wi-Fi, to help prevent collisions from occurring in the first place.
What is tokens as in token ring networks?
The token is a special 3 byte sequence that indicates the state of the ring; it may mark the ring as in-use, or free (anyone can use it), or health status. Any client needs to have access to the token before transmitting or receiving on the ring network.
