# What field in a frame determines if errors occurred in the transmission and reception?

## What field in a frame determines if errors occurred in the transmission and reception?

The Frame Check Sequence (FCS) field is used to determine if errors occurred in the transmission and reception of the frame.

### What is the function of the CRC value that is found in the FCS field of a frame?

What is the function of the CRC value that is found in the FCS field of a frame? Explanation: The CRC value in the FCS field of the received frame is compared to the computed CRC value of that frame, in order to verify the integrity of the frame. If the two values do not match, then the frame is discarded.

#### What action will occur if a switch receives a frame and does have the source MAC address in the MAC table?

What action will occur if a switch receives a frame and does have the source MAC address in the MAC table? The switch refreshes the timer on that entry. Which two functions are performed at the MAC sublayer of the OSI data link layer? (Choose two.)

Which three fields are found in an 802.3 Ethernet frame?

Answers Explanation & Hints: The fields of an Ethernet frame are the preamble, destination and source address, length, data, and FCS.

What is FCS field in a frame?

The FCS field in a frame is used to detect any errors in the transmission and receipt of a frame. If the two values do not match, then the frame is discarded.

## Which part of an Ethernet frame detects errors in the frame?

frame check sequence (FCS)
The frame check sequence (FCS) field (4 bytes) is used to detect errors in a frame. It uses a cyclic redundancy check (CRC).

### Which switching method uses the CRC value in a frame?

Explanation:When the store-and-forward switching method is used, the switch receives the complete frame before forwarding it on to the destination. The cyclic redundancy check (CRC) part of the trailer is used to determine if the frame has been modified during transit.

#### What action will occur if a switch receives a frame and does not?

The switch does not forward the frame. The switch sends the frame to a connected router because the destination MAC address is not local.

What is the FCS field used for in an Ethernet frame?

A frame check sequence (FCS) is an error-detecting code added to a frame in a communication protocol. Frames are used to send payload data from a source to a destination.

What is FCS field?

The FCS field contains a number that is calculated by the source node based on the data in the frame. This number is added to the end of a frame that is sent. If the two numbers are different, an error is assumed and the frame is discarded. The FCS provides error detection only.

## What is the purpose of the field in a frame?

The FCS field in a frame is used to detect any errors in the transmission and receipt of a frame. This is done by comparing the CRC value within the frame against a computed CRC value of the frame. If the two values do not match, then the frame is discarded.

### What is the purpose of the FCS field in a frame?

The FCS field in a frame is used to detect any errors in the transmission and receipt of a frame. This is done by comparing the CRC value within the frame against a computed CRC value of the frame. If the two values do not match, then the frame is discarded. For more question and answers:

#### What are the header fields of an Ethernet frame?

They all include the flow control and logical connection fields. Ethernet frame header fields contain Layer 3 source and destination addresses.

How is crosstalk related to the magnetic field?

Explanation: Crosstalk is a type of noise, or interference that occurs when signal transmission on one wire interferes with another wire. When current flows through a wire a magnetic field is produced. The produced magnetic field will interface the signal carried in the adjacent wire.

What is carrier sense multiple access collision detection ( CSMA / CD )?

message encoding. Explanation: Carrier sense multiple access collision detection (CSMA/CD) is the access method used with Ethernet. The access method rule of communication dictates how a network device is able to place a signal on the carrier.
