What else can I help you with?
The data portion of an ethernet frame may contain bytes of information?
46 to 1500
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 added when extra filler data is needed in a packet?
In Computer networking, you have data that is transmitted through packets. In which is what we call an Ethernet frame. That Ethernet frame broken up into several pieces. They are:The PreambleRecipient's MACSender MACTypeData (Your information)Pad (FILLER)FCSThe reason why we have the "Pad" is because your standard minimum for an Ethernet frame size is 64 bytes. However, it doesn't all have to be your actual data. For example, if you were to send data that was not 64 bytes. Your NIC (Network Interface Card) will automatically add extra data which is what we can the "Pad" portion. This adds data so that we are back up to the minimum value of 64 bytes within an Ethernet frame.
The largest possible data field in an Ethernet frame is?
The largest possible data field in an Ethernet frame, known as the Maximum Transmission Unit (MTU), is typically 1500 bytes for standard Ethernet frames. This includes the payload or data portion, while the total frame size can reach up to 1518 bytes when including headers and trailers. In some specialized Ethernet variants, such as Jumbo Frames, the MTU can be increased to 9000 bytes or more, but this is not universally supported across all networks.
A device receives an Ethernet frame and recognizes the MAC address as its own. What does the device do to the message to get to the encapsulated data?
Removes the Ethernet header and trailer
What protocols are in the Ethernet frame?
The ethernet frame carries the IP (Internet Protocol) The Ethernet frame is made up of the following: 7 BYTE PREAMBLE 1 Byte "Start OF Frame" delimiter 6 byte destination address 6 byte source address 2 byte length or type 46 - 1500 bytes variable 802.2 or ethernet header and data 4 byte Frame Check sequence
What is contained in the data portion of a windows ping frame?
alphabet
Within ethernet frame types what signals to the receiving node that data is incoming and indicates when the data flow is about to begin?
preamble
What is Ethernet header?
An Ethernet header is a portion of data that precedes the payload in an Ethernet frame, containing essential information for data transmission over a network. It typically includes the source and destination MAC addresses, the EtherType field to indicate the protocol used in the payload, and other control information. The header enables devices on a local area network (LAN) to identify and process the incoming frames correctly. In standard Ethernet frames, the header is usually 14 bytes long.
What is the purpose of the 7-byte preamble and 1-byte start-of-frame delimiter on an Ethernet frame?
The purpose is the preamble signals to the receiving node that data is incoming and indicates when the data flow is about to begin. The SFD (start-of-frame delimiter) identifies where the data field begans.
How much data can a typical frame contain?
1500 bytes
What is the fuction of the FCS field in an Ethernet frame?
The FCS (Frame Check Sequence) Component of an ethernet frame permits the end recipient to check for, and correct, errors in the packet. It is a checksum that is checked against the packet for data integrity, to put it simply. When the number does not check out properly, the frame is thrown out and a replacement packet is requested.
