M-law companding is a type of non-linear (logarithmic) quantizing, companding and encoding techniques for speech signals based on the m-law. This type of companding uses a m factor of 255 and is optimized to provide a good signal-to-quantizing noise ratio over a wide dynamic range.
A brand name and registered trademark for a line of computers from Apple Inc.
Media Access Control address. The physical address of a device connected to a network, expressed as a 48-bit hexadecimal number.
MAC address (Media Access Control address) is the address associated with every hardware device on the network. Every wireless 802.11 device has its own specific MAC address hard-coded into it. This unique identifier can be used to provide security for wireless networks. When a network uses a MAC table, only the 802.11 radios that have had their MAC addresses added to that network's MAC table are able to get onto the network.
MAC address, short for Media Access Control address, is a unique hardware address assigned to each network device. In the case of Ethernet, the hardware address is a 48-bit value. To guarantee global uniqueness, the upper 24 bits are controlled by the IEEE, which allocates them to individual device manufacturers.
MAC Layer, short for Media Access Control Layer, is one of two sublayers that make up the Data Link Layer of the OSI model. The MAC layer is responsible for moving data packets to and from one Network Interface Card (NIC) to another across a shared channel.
See a breakdown of the seven OSI layers in the Quick Reference section of Webopedia.
|Mac OS X|
Mac OS X is the tenth and the latest version of the Macintosh operating system, and is designed and developed by Apple Computer to run on their Macintosh line of personal computers. Mac OS X is built on Darwin, an open source Unix-like environment which is based on the BSD source tree, and the Mach microkernel.
|Mac OS: Macintosh Operating System|
Macintosh operating system (Mac OS). is a series of graphical user interface-based operating systems developed by Apple Computer for their Macintosh line of computer systems. It was first introduced in 1984 with the original Macintosh 128K. Earlier versions of the Mac OS were compatible only with Motorola 68000-based Macintoshes, while later versions were also compatible with the PowerPC (PPC) architecture. Most recently, Mac OS X has become compatible with Intel's PC CPU architecture.
Medium Access Control protocol. In a local area network, the protocol that determines which device has access to the transmission medium at a given time.
Medium Access Control sublayer. The lower sublayer of the data link layer, which uses the network's physical layer to provide services to the logical link control (LLC). The functions of the MAC sublayer vary according to the topology of the network.
A tool for developing application programs on the Macintosh, using object-oriented Pascal.
A benchmark from Ziff-Davis that measures the processor, floating point, disk, graphics, video, and CD-ROM performance of a MacOS, giving an idea of how well a particular system will run common Macintosh applications.
Macintosh files, unlike files from other computer platforms which hold data only, have a resource fork and a data fork. If Mac files are put on a non-Mac machine, the resource fork will be stripped off, rendering some files unusable. MacBinary encoding prevents loss of the resource fork when posting the file to a non-Mac platform, by attaching the resource and data forks together in a single data file. MacBinary files must be transferred using an 8-bit, binary mode. They often have .bin as a filename extension.
A Macintosh decompression program that can expand .zoo files.
The Mac version of the Compress program for DOS and UNIX. It creates files with the .Z suffix.
A drawing program for the Macintosh.
A version of gzip for Macintosh, made by SPDsoft. It compresses Mac files into gzip files; the Mac resource fork is lost unless a MacBinary translator is used first. The gunzip function decompresses .gz, .Z, .z, and .tgz files.
Readable by a computer; softcopy is machinable.
A device which performs a task and is operated mechanically, electrically, or electronically. In computer terminology, "machine" refers to the computer itself.
An address that is permanently assigned to a specific storage location in a computer, by the maker of the machine.
