A frame begins with preamble and start frame delimiter, followed by an Ethernet header featuring source and destination MAC addresses.

* 802. 3 ( raw ) is used in legacy systems and involves IPX data starting immediately after 802. 3 frame header.

* 802. 2 ( Novell ) comprises 802. 3 frame header ( destination, source, length ) followed by LLC header ( 3 bytes-0xE0, 0xE0, 0x03 ) followed by IPX data.

* 802. 2 ( SNAP ) comprises 802. 3 frame header, LLC header ( 3 bytes-0xAA, 0xAA, 0x03 ), SNAP header ( 5 bytes-0x00, 0x00, 0x00, 0x81, 0x37 ) and IPX data.

* Ethernet II comprise an Ethernet II frame header ( Destination, Source, EtherType ) followed by IPX data.

IEEE 802. 3 is an exception ; Ethernet originally used Ethernet II framing, with a 2-octet type field containing an EtherType value, and no 802. 2 header, but the original IEEE 802. 3 specification used a framing wherein the 2-octet field following the 6-octet destination and source MAC addresses contained a frame length, with an 802. 2 LLC header following the length field.

* Priority Code Point, a three-bit priority field within an Ethernet frame header when using IEEE 802. 1q tagged frames.

For example, in Ethernet the maximum frame size 1526 bytes ( maximum 1500 byte payload + 8 byte preamble + 14 byte header + 4 Byte trailer ).

This sub-chunk is the file header and contains metadata about the video, such as its width, height and frame rate.

In packet-oriented data transmission, such as Ethernet, a packet frame usually consists of a header and a payload.

They both settled on essentially a 48-byte data frame with a 5-byte header.

A frame is " the unit of transmission in a link layer protocol, and consists of a link-layer header followed by a packet.

The data signaling rate actually observed on real networks is less than the theoretical maximum, due to the necessary header and trailer ( addressing and error-detection bits ) on every frame, the occasional " lost frame " due to noise, and time waiting after each sent frame for other devices on the network to finish transmitting.

** These frames all had the same type of " envelope " ( frame header and trailer ) which contained enough information for data packages from different types of terminal to be send along the same communications line, leaving the mainframe to deal with any differences in the formatting of the content or in the rules governing dialogs with different types of terminal.

This " color " is what is now known in the Ethernet frame as the 802. 1Q header, or the VLAN tag.

Cisco also implemented VLANs over FDDI by carrying VLAN information in an IEEE 802. 10 frame header, contrary to the purpose of the IEEE 802. 10 standard.

With ISL, an Ethernet frame is encapsulated with a header that transports VLAN IDs between switches and routers.

The fields in an ISL header identify the frame as belonging to a particular VLAN.

Down through the axis of the bridge there is a long diminishing vista like a visual echo of piers and arches, while the vaults fronting upstream and down frame the sunset and sunrise, the mountains and river pools.

Within this frame of reference policies appropriate to claims advanced in the name of the Jews depend upon which Jewish identity is involved, as well as upon the nature of the claim, the characteristics of the claimant, the justifications proposed, and the predispositions of the community decision makers who are called upon to act.

When decision makers act within this frame they determine whether a claim put forward in the name of religion is to be accepted by the larger community as appropriate to religion.

It is the consequence of the system of ideas that constitutes the frame of our international -- and in some degree our domestic -- policy.

The difference is that the masters took the bare frame of a plot and filled it with their own world ; ;

It was the kind of frame that is only put around the photograph of a dead person.

If you do use a cold frame be sure that its ventilation is adequate.

The design of a mechanical interlocking frame is much like a mechanical puzzle, but once understood, the principles can be applied to any track and signal arrangement.

The interlocking frame we built at the model railroader workshop and then installed on Paul Larson's railroad follows the Fig. 1 scheme and is shown beginning in Fig. 7, page 65, and in the photos.

Our instructions assume you are building this particular frame, which is for a junction.

As the work progresses the frame and moving parts become a sort of Chinese puzzle where several pieces must be removed before the part you are working on is accessible.

The transom frame is made first with the joints lapped, glued and fastened with one-inch, No. 12 Stronghold nails.

A stem jig is next cut to the proper shape and temporarily fastened to frame one.

It is recommended that panels be both glued as well as nailed to the frame.

Finish your plumbing before you frame it in ( most economical framing is a thin non-bearing partition on either side of the pipes ).

It also provides a frame within which the registration of vital events is gradually gaining force ( though one cannot expect to obtain reliable vital statistics in most parts of the Congo from this source in the near future ).

There is also the problem of the respondent's frame of reference.

The typical appearance of these various mechanisms is illustrated in Figs. 2, 3, and 4, which are single frame enlargements of high speed movies taken during the course of the knife removal process.

The minimum diameter of the pin frame in the collapsed state is 11 inches and the maximum diameter in the freely extended state ( unloaded ) is 14 inches.

If he is not told which of four or five readings was meant for him, he can more readily assess each item in a larger frame: `` Does that statement really sound as if it were for me, significant in my particular life??

Each frame comes between the light and the lens and is individually projected on the screen, at the rate, for silent movies, of 16 frames per second, and, for sound films, 24 frames per second.

The abacus ( plural abaci or abacuses ), also called a counting frame, is a calculating tool used primarily in parts of Asia for performing arithmetic processes.

Bricks are made in an open frame, by being a reasonable size, but any convenient size is acceptable.

The mixture is molded by the frame, and then the frame is removed quickly.
