In IEEE 802. 3x-1997, the IEEE Ethernet standard was changed to explicitly allow the use of the 16-bit field after the MAC addresses to be used as a length field or a type field.

It was the machine that made time-sharing common ; it looms large in hacker folklore because of its adoption in the 1970s by many university computing facilities and research labs, the most notable of which were MIT's AI Lab and Project MAC, Stanford's SAIL, Computer Center Corporation ( CCC ), and Carnegie Mellon University.

It originated at MIT's Project MAC ( from which it derived its prefix ) in the late 1960s and was based on Lisp 1. 5.

MACLISP was named for Project MAC, and is unrelated to Apple's Macintosh (" Mac ") computer, which it predates by many years.

* MAC times, file system metadata which record when an object was last " modified " ( contents ), " accessed " ( read ), and " changed " ( permissions )

: I think that the most fun I had programming was a summer job at Project MAC at MIT in the summer of 1966, where I worked on a program that created a job tape for the brand new GE 645 in the earliest days of Multics.

The earliest work directed toward standardizing an approach toward provision of mandatory and discretionary access controls ( MAC and DAC ) within a UNIX ( more precisely, POSIX ) computing environment can be attributed to the National Security Agency's Trusted UNIX ( TRUSIX ) Working Group, which met from 1987 to 1991 and published one Rainbow Book (# 020A ) and produced a formal model and associated evaluation evidence prototype (# 020B ) that was ultimately unpublished.

In the following years, the Israel-Egypt MAC remained inactive, though UNTSO was occasionally called to investigate incidents involving often bedouins in the Negev.

The MAC also condemned this act by Israel and called upon the Israeli authorities to take the strongest measures to prevent a recurrence of such a breach of the GAA and to refrain in the future from bringing to Jerusalem any equipment that was in excess of that allowed for under the terms of the GAA.

Prior to the development of RBAC, the Bell-LaPadula model ( BLP ) model was synonymous with MAC and file system permissions were synonymous with DAC.

An emergency meeting of the Mixed Armistice Commission ( MAC ) was held in the afternoon of 15 October and a resolution condemning the regular Israel army for its attack on Qibya, as a breach of article III, paragraph 2, 62 / of the Israel-Jordan General Armistice Agreement was adopted by a majority vote.

The Louisville Cardinals were a MAC affiliate for field hockey for a number of years when Louisville was a member of the Metro Conference and Conference USA, winning two MAC tourney titles in 2003 and 2004.

The airline was founded on 24 May 1958 as Martin's Air Charter ( MAC ), by Martin Schröder and John Block, with one aircraft, a de Havilland Dove and five employees.

RuPaul was signed to a modeling contract for MAC Cosmetics, making him the first drag queen supermodel.

On August 7, 1935, Escobar defeated Peter Santol, who was considered Canada's best bantaweight and held the Canadian Boxing Federation & Montreal Athletic Commission ( MAC ) world titles, by unanimous decision in 12 rounds.

Due to this, Santol sent a letter to the NYSAC noting that the fight was of eliminatory nature, even though it was recognized as a titular contest by the NBA and MAC.

* Al Fisher ( born 1986 ), basketball player for Kent State University ; was named 2008 MAC PLayer of the Year.

ACC was created when SAC, TAC, and the Military Airlift Command ( MAC ) merged to form two commands, ACC and the Air Mobility Command ( AMC ).

In January 2007, Welch was selected as the newest face of MAC Cosmetics Beauty Icon series.

* The Compatible Time-Sharing System ( CTSS ), one of the first time-sharing operating systems, was developed at MIT's Project MAC using a 7094 with an extra bank of memory, among other modifications.

Ma was deputy secretary-general of the KMT from 1984 to 1988, also serving for a period as deputy of the Mainland Affairs Council ( MAC ), a cabinet-level body in charge of cross-straits relations.

Conceptually, the original ( version 1 ) generation scheme for UUIDs was to concatenate the UUID version with the MAC address of the computer that is generating the UUID, and with the number of 100-nanosecond intervals since the adoption of the Gregorian calendar in the West.

The Israel-Lebanon MAC met regularly and had developed a routine for handling incidents that occurred.

TOMOYO Linux introduced the " learning " mode, in which the accesses occurred in the kernel are automatically analyzed and stored to generate MAC policy: this mode can be used as first step of policy writing, making it easy to customize later.

MAC times are pieces of file system metadata which record when certain events pertaining to a computer file occurred most recently.

Even when an address is not based on the MAC address though, the interface's address is ( contrary to IPv4 ) usually global instead of local, which makes it much easier to identify a single user through the IP address.

Now, when another node wired into the Ethernet wants to talk to the dial-up node, it will ask on the network for the MAC address of 192. 168. 0. 254 and find the access server's MAC address.

The Reverse Address Resolution Protocol ( RARP ) is an obsolete computer networking protocol used by a host computer to request its Internet Protocol ( IPv4 ) address from an administrative host, when it has available its Link Layer or hardware address, such as a MAC address.

* Multiplexing protocols transmitted over the MAC layer ( when transmitting ) and decoding them ( when receiving ).

For example, while HDLC specifies both MAC functions ( framing of packets ) and LLC functions ( protocol multiplexing, flow control, detection, and error control through a retransmission of dropped packets when indicated ), some protocols such as Cisco HDLC can use HDLC-like packet framing and their own LLC protocol.

As NTL had not supported the use of routers, or Xbox on the minority Set Top Box based Broadband Internet service, users had to use a clone MAC address feature to connect to the Internet when using an STB.

Throughout these periods of World War II when air interdiction was practiced and developed, Tedder was always at the forefront as Air Commander-in-Chief of RAF Middle East Command, Mediterranean Air Command ( MAC ), Mediterranean Allied Air Forces, and as Gen. Dwight D. Eisenhower's Deputy Supreme Allied Commander for planning the air operations of the Normandy campaign.

Thus, when an IP packet reaches its destination ( sub ) network, the destination IP address ( a layer 3 or network layer concept ) is resolved with the Address Resolution Protocol for IPv4, or by Neighbor Discovery Protocol ( IPv6 ) into the MAC address ( a layer 2 concept ) of the destination host.

Ironically the past-deadline encryption system in the DMAC silicon chip technology was one primary reason for BSB having to merge with Sky and hence the Far Eastern TV manufacturers had largely unfettered access to the market when MAC was dropped in favour of PAL.

Network interface cards have a DLC address that identifies each card ; for instance, Ethernet and other types of cards have a 48-bit MAC address built into the cards ' firmware when they are manufactured.

For example, when a network switch receives a data frame from one of its ports, it updates an internal table with the frame's source MAC address and the port it was received on.

This clip permits the MAU and MAC to be directly attached to one another even when their size and shape would preclude the use of thumbscrews.

In non-promiscuous mode, when a NIC receives a frame, it normally drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast frame.

On July 1, 1977, the base once again changed hands as the 1606th Air Base Wing was created when Military Airlift Command ( MAC ) took over responsibility for operating Kirtland AFB from Air Force Systems Command.

This address is used by only one physical router at a time, and it will reply with this MAC address when an ARP request is sent for the virtual router's IP address.

These three competing awards began merging three years later when the NSCAA and MAC agreed to cooperate on naming a combined collegiate player of the year.

It generates a log of observed pairing of IP addresses with MAC addresses along with a timestamp when the pairing appeared on the network.

On October 1, 1986, the 189 ARG saw yet another mission change when it was redesignated as the 189th Tactical Airlift Group ( 189 TAG ) and converted to the C-130 aircraft, with transfer of operational claimancy to MAC.
