Cytochrome c is also released from mitochondria due to formation of a channel, the mitochondrial apoptosis-induced channel ( MAC ), in the outer mitochondrial membrane, and serves a regulatory function as it precedes morphological change associated with apoptosis.

MAC, also called " Mitochondrial Outer Membrane Permeabilization Pore " is regulated by various proteins, such as those encoded by the mammalian Bcl-2 family of anti-apoptopic genes, the homologs of the ced-9 gene found in C. elegans.

This is achieved by designating one or more " server " or " provider " nodes, either by MAC address or switch port.

This feature, which is not supported by all DHCP servers, is variously called Static DHCP Assignment by DD-WRT, fixed-address by the dhcpd documentation, Address Reservation by Netgear, DHCP reservation or Static DHCP by Cisco and Linksys, and IP reservation or MAC / IP binding by various other router manufacturers.

This message contains the client's MAC address, the IP address that the server is offering, the subnet mask, the lease duration, and the IP address of the DHCP server making the offer.

As with other IEEE 802 LANs, each Ethernet station is given a 48-bit MAC address.

< span id =" switch_vulnerabilities "> Despite this, switched Ethernet should still be regarded as an insecure network technology, because it is easy to subvert switched Ethernet systems by means such as ARP spoofing and MAC flooding .</ span >

IEEE 802. 3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer's media access control ( MAC ) of wired Ethernet.

* Hosts have a 48-bit node address which by default is set to the network interface card's MAC address.

As the node address is usually identical to the MAC address of the network adapter, the Address Resolution Protocol is not needed.

Beneath the LLC sublayer is the Media Access Control ( MAC ) sublayer, which is dependent on the particular medium being used ( Ethernet, token ring, FDDI, 802. 11, etc.

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.

Interfaces can have addresses based on the MAC address of the machine ( the EUI-64 format ), but this is not a requirement.

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.

SHA-1 HMAC Generation. In cryptography, a hash-based message authentication code ( HMAC ) is a specific construction for calculating a message authentication code ( MAC ) involving a cryptographic hash function in combination with a secret cryptographic key.

Layer 2 switching is hardware based, which means switches use application-specific integrated circuit ( ASICs ) to build and maintain filter tables ( also known as MAC address tables ).

The MAC may be linked to the PHY by a 4 bit 25 MHz synchronous parallel interface known as a Media Independent Interface ( MII ) or a 2 bit 50 MHz variant Reduced Media Independent Interface ( RMII ).

A channel-access scheme is also based on a multiple access protocol and control mechanism, also known as media access control ( MAC ).

The channel access control mechanisms provided by the MAC layer are also known as a multiple access protocol.

The Malkin Athletic Center, known as the " MAC ," serves both as the university's primary recreation facility and as home to the varsity men's and women's volleyball, men's and women's fencing, and wrestling teams.

The hardware unit that performs the operation is known as a multiplier – accumulator ( MAC, or MAC unit ); the operation itself is also often called a MAC or a MAC operation.

When another host's IP address is known, and its MAC address is needed, a broadcast packet is sent out on the local network.

A MAC algorithm, sometimes called a keyed ( cryptographic ) hash function, accepts as input a secret key and an arbitrary-length message to be authenticated, and outputs a MAC ( sometimes known as a tag ).

In MAC addressing ( layer 2 on the OSI model ), the broadcast address is the MAC address FF: FF: FF: FF: FF: FF, otherwise known as the " all F " address.

" MAC Madness ", as it is known, has become a strong draw for the arena.

Subsequently, E & D's engineers proposed a system of analogue television encoding known as MAC ( Multiplexed Analogue Component ) to provide a standard for the forthcoming satellite television broadcasts that was more robust than an extension of the existing PAL system used for terrestrial broadcasts.

The MAC is responsible for the planning, development, and implementation of policies between the Free Area of the Republic of China, commonly known as Taiwan, and the People's Republic of China, which governs mainland China, Hong Kong, and Macau.

These areas are managed and maintained by an Area team and a contractor, known as a Managing Agent ( MA ) or Managing Agent Contractor ( MAC ).

836 returned aboard the Woolworth-class carrier HMS Biter to be re-formed to provide personnel and aircraft for the MAC ships, 836 was later based at Maydown, known as HMS Shrike, in Northern Ireland, not far from Lough Foyle, and commanded by Lieutenant-Commander Ransford Slater.

The office's hosts will send packets addressed to IPs within this range directly, by resolving the destination IP address into a MAC address through an ARP sequence ( if not already known through the host's ARP cache ) and then enveloping the IP packet into a layer 2 ( MAC ) packet addressed to the destination host.

In the 1960s two movements were established in protest against the drowning of the Tryweryn valley and the 1969 investiture of Charles, Prince of Wales: Mudiad Amddiffyn Cymru (' Movement for the Defence of Wales ', also known as MAC ) and the Free Wales Army ( also known as FWA, in Welsh ' Byddin Rhyddid Cymru ').

On occasion, the bank made headlines for quiet innovations, such as when during the late 1960s it led all the nation's banks in ending the practice of " redlining " poorer neighborhoods so that personal and small business loans could not be extended to residents of poorer city district, or when, during the middle 1970s, the bank helped universalize ATM banking by building one of the nation's first and largest network of banking machines, known by their acronym, " MAC ", for Money Access Center.

If it is a broadcast frame, or the MAC address is not known to the PE, it floods the frame to all PEs in the mesh.

* Requires destination computer MAC address ( also may require a SecureOn password )

* ANSI X3. 139-1987, Media Access Control ( MAC ) — also ISO 9314-2

Therefore, not only the measure but also the position of MAC is often important.

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.

As well as serving as docking stations for UNSC ships, MAC stations such as Cairo Station also possess a massive coilgun, which serve to ward off assaulting enemy fleets via long-range bombardments.

This can be done using the MAC ( Machine Access Control ) addresses from Bluetooth devices, or using the RFID serial numbers from Electronic Toll Collection ( ETC ) transponders ( also called " toll tags ").

Mac Process ( formally MAC Equipment ) is also a large employer in the area, manufacturing bulk material handling and air filtration equipment.

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.

The control can also detect the presence of a receiver, which allows direct communication and MAC synchronization.

Multics, which was also developed by Project MAC, was started in the 1960s as a successor to CTSS, for future use in multiple-access computing.

ITS, the Incompatible Timesharing System ( named in comparison with the Compatible Time-Sharing System also in use at MIT ), was an early, revolutionary, and influential time-sharing operating system from MIT ; it was developed principally by the Artificial Intelligence Laboratory at MIT, with some help from Project MAC.

The MAC also offers personal trainers and specialty classes.

The MAC is also home to volleyball, fencing, and wrestling.

The offices of several of the school's varsity coaches are also in the MAC.

Four " Specialty MAC Jurisdictions " were also created to handle durable medical equipment and home health / hospice claims:

The C-5 Galaxy strategic airlifter, also inherited from MAC, is being modernized and upgraded into the C-5M Super Galaxy model.

The monitors also usually measure nitrous oxide and oxygen percentages and could give a MAC level.
