Besides, what is the function of the CRC value that is found in the FCS field of a frame quizlet?
To verify the integrity of the received frame.
Subsequently, question is, what are two reasons physical layer protocols use frame encoding techniques? (Choose two.)
- to reduce the number of collisions on the media.
- to distinguish data bits from control bits.
- to provide better media error correction.
- to identify where the frame starts and ends.
- to increase the media throughput. Explanation:
Also asked, what is the function of the CRC value?
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
What are two examples of hybrid topologies?
(Choose two.)
- partial mesh.
- extended star.
- hub and spoke.
- point-to-point.
- full mesh. Explanation: A hybrid topology is one that is a variation or a combination of other topologies. Both partial mesh and the extended star are examples of hybrid topologies.
When a switch receives a frame on a port and floods the frame What does it do with the frame?
When a switch receives a frame on a port and floods the frame, what does it do with the frame? Forwards it out to all other connected ports. You have two-eight port switches. On each switch, seven stations are connected to ports, and the two switches are connected with the eighth port.Which switching method uses the CRC value in a frame?
The cyclic redundancy check (CRC) part of the trailer is used to determine if the frame has been modified during transit. ?? In contrast, a cut-through switch forwards the frame once the destination Layer 2 address is read. Two types of cut-through switching methods are fast-forward and fragment-free.What is the definition of bandwidth Cisco?
Explanation: Bandwidth is the measure of the capacity of a network medium to carry data. It is the amount of data that can move between two points on the network over a specific period of time, typically one second.What are the contents of the data field in a frame?
Fields of a Data Link Layer Frame A data link layer frame has the following parts: Frame Header: It contains the source and the destination addresses of the frame and the control bytes. Payload field: It contains the message to be delivered. Trailer: It contains the error detection and error correction bits.What is the definition of bandwidth quizlet?
bandwidth. defined as the amount of data that can be transmitted in a fixed amount of time. For digital devices, the bandwidth is usually expressed in bits per second(bps) or bytes per second.Which types of UTP cables can be used to connect the devices?
An RJ-45 connector is used with UTP cabling. The two types of connections are straight-through and crossover. Straight-through cables are typically used to connect different devices, such as switch-to router connections.What three services are provided by the transport layer choose three?
What three services are provided by the transport layer? ( Choose three.)- flow control.
- encryption of data.
- path determination.
- connection establishment.
- error recovery.
- bit transmission.
- data representation.
Which type of connector does a network interface?
Different network interfaces are applicable to different network types. Currently, common interfaces are Ethernet RJ-45 connector, BNC connector of thin coaxial cable, coarse coaxial AUI interface, FDDI connector and ATM connector etc.What type of communication will send a message to all devices on a local area network?
What type of communication will send a message to all devices on a local area network? Explanation:Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication. Multicast is a one-to-many communication where the message is delivered to a specific group of hosts.What is the aim of an ARP spoofing attack?
Anatomy of an ARP spoofing attack Generally, the goal of the attack is to associate the attacker's host MAC address with the IP address of a target host, so that any traffic meant for the target host will be sent to the attacker's host.What is CRC and FCS?
The algorithm that is used to generate the FCS is a Cyclic Redundancy Check(CRC). The CRC algorithm is used by a number of technologies, and not restricted to networking. But FCS is specific to ethernet framing.What is the role of the Logical Link Control sublayer?
The Logical Link Control (LLC) sublayer provides the logic for the data link; thus it controls the synchronization, flow control, and error-checking functions of the data link layer.Which two functions are performed at the MAC sublayer of the OSI data link layer?
The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.What is indicated by the term throughput quizlet?
What is indicated by the term throughput? the measure of the bits transferred across the media over a given period of time. A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals.What is the purpose of the OSI physical layer?
What is the purpose of the OSI physical layer? The physical layer is responsible for transmitting the actual signals across the physical media as bits. Exchanging frames, controlling media access, and performing error detection are all functions of the data link layer.What are two potential network problems that can result from ARP operation choose two?
What are two potential network problems that can result from ARP operation? On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.What are two characteristics of a scalable network choose two?
What are two characteristics of a scalable network? Grows in size without impacting existing users. Why do multiple ISP's connect to an IXP or a NAP? To gain access to each other's networks.ncG1vNJzZmiemaOxorrYmqWsr5Wne6S7zGiuoZmkYra0edOhnGaepaOwtbXOp2Sonl2ptaZ5wquaZq6RocKmedOhmK1lmah6p7vUp5tmoZ5iwamxjJ%2BarGWWnrKtsIyonWaZXZu%2FornE
