What else can I help you with?
How much data can a typical frame contain?
1500 bytes
Which field of an Ethernet frame is used for error detection?
c) Check frame sequence. The FCS (4 bytes in length) field is used to detect errors in a frame
What is the minimum and maximum size of an Ethernet frame?
The minimum size of an Ethernet frame is 64 bytes. Even if the VLAN tag is 4 bytes, the Ethernet frame with VLAN tagging remains 64 bytes.
How many bytes is the data frame made by FCS and the header together?
14 bytes for the header and 4 bytes for the FCS (Frame Check Sequence) for a total of 18 bytes.
Ethernet frame required minimum of 64 bytes why?
ethernet frame required minimum of 64 bytes expalin why?
What is the size of an Ethernet frame carrying an APR packet?
An Ethernet frame typically has a maximum payload size of 1500 bytes, which includes the APR (Address Resolution Protocol) packet. The APR packet itself is relatively small, usually around 28 bytes, allowing the Ethernet frame to accommodate additional headers and trailers, such as the Ethernet header (14 bytes) and the Frame Check Sequence (4 bytes). Therefore, the total size of an Ethernet frame carrying an APR packet would be at least 64 bytes (minimum frame size) up to 1518 bytes (maximum frame size).
How many bytes on a blank CD?
A Music CD can hold up to 700Mbs, which equals to 700,000,000 bytes, aprox.
Why 64 bytes minimum in ieee 802.3?
FOR THE 802.3 FRAME CONTAINS Ethernet Header = 18 Bytes [Dst Mac(6) + Src Mac(6) + Length (2) +CRC(4)]Minimum Data Portion = 46 BytesMinimum Ethernet Frame Size = 64 Bytes Frames must be at least 64 bytes long, not including the preamble, so, if the data field is shorter than 46 bytes, it must be compensated by the Padfield. The reason for specifying a minimum length lies with the collision-detect mechanism. In CSMA/CD a station must never be allowed to believe it has transmitted a frame successfully if that frame has, in fact, experienced a collision. In the worst case it takes twice the maximum propagation delay across the network before a station can be sure that a transmission has been successful. If a station sends a really short frame, it may actually finish sending and release the Ether without realising that a collision has occurred. THATS WHY IT IS MINIMUM 64 BYTES
What is a block length?
In computing, a block length is the length, in bytes or characters, of a block of data.
What is the purpose of padding in an Ethernet frame?
ensuring that the data portion of the frame totals at least 46 bytes
What is the maximum number of bytes that is allowed in a standard IEEE 802.3 Ethernet frame?
Totally depends on the hardware and software and their MTU (Maximum Transmission Unit). Usually MTU is set to 1500 bytes.
What is the length of the instruction queue in 8086?
6 bytes
