What are the 5 parts of Ethernet frame?
Ethernet header contains five fields; Preamble, SFD, Destination, Source, and Type.
What are Ethernet frame fields?
In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields.
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 are the parts of an Ethernet frame Mcq answer?
This set of Computer Networks Multiple Choice Questions & Answers (MCQs) focuses on “Ethernet”. Explanation: The Ethernet frame has a header that contains the source and destination MAC address. Each MAC address is of 48 bits.
Which component is part of an Ethernet frame?
In general, an Ethernet frame consists of 3 parts. They are Ethernet header (Preamble, SFD, Destination, Source and Type), Encapsulated data (Data and Pad), and Ethernet trailer (FCS).
What are the parts of Ethernet frame Mcq?
What are Ethernet standard 802.3 and frame formats?
Ethernet (IEEE 802.3) Frame Format –
- PREAMBLE – Ethernet frame starts with 7-Bytes Preamble.
- Start of frame delimiter (SFD) – This is a 1-Byte field which is always set to 10101011.
- Destination Address – This is 6-Byte field which contains the MAC address of machine for which data is destined.
How many addresses does an 802.3 frame have?
802.3 frames have only a source address (SA) and destination address (DA) in the layer 2 header. 802.11 frames have up to four address fields in the MAC header. 802.11 frames typically use only three of the MAC address fields (4 in WDS environment).
What is the 2 byte type field used for in an Ethernet frame Mcq?
Length – Length is a 2-Byte field, which indicates the length of entire Ethernet frame.
Where is the start frame delimiter found in an Ethernet frame?
preamble
A preamble and start frame delimiter are part of the packet at the physical layer. The first two fields of each frame are destinations and source addresses.
What is the Ethernet frame fields, computer networking?
An Ethernet frame is a way of arranging sections of data for transfer over a computer network. The frame is the one of the key elements of the Ethernet system, one of the most popular types of local network. It is made up of three elements: a pair of addresses, the data itself, and an error checking field.
What does the FCS field in an Ethernet frame do?
What is the function of the FCS field in an Ethernet frame? Preamble and start frame delimiter. An Ethernet frame inside an Ethernet packet, with SFD marking the end of the packet preamble and indicating the beginning of the frame. Header. Payload. Frame check sequence.
What does the format for Ethernet frames specify?
Ethernet (IEEE 802.3) Frame Format – PREAMBLE – Ethernet frame starts with 7-Bytes Preamble. Start of frame delimiter (SFD) – This is a 1-Byte field which is always set to 10101011. Destination Address – This is 6-Byte field which contains the MAC address of machine for which data is destined. Source Address – This is a 6-Byte field which contains the MAC address of source machine.
How are Ethernet frame sizes defined?
The frame size of a standard Ethernet frame (defined by RFC 894) is the sum of the Ethernet header (14 bytes), the payload (IP packet, usually 1,500 bytes), and the Frame Check Sequence (FCS) field (4 bytes). The MTU size specifies the maximum number of bytes of data (the payload) that can be encapsulated in an Ethernet frame.
