The background on top of which all windows appear; the working environment displayed on Mac computers.
Industry:Software; Computer
A filter that alters IP traffic each time it enters the protocol stack. By its very nature, an IP filter can only filter in-band communication.
Industry:Software; Computer
Interprocess communication. A set of programming interfaces that enables a process to communicate data or information to another process. Mechanisms for IPC exist in the various layers of the system, from Mach messaging in the kernel to distributed notifications and Apple events in the application environments. Each IPC mechanism has its own advantages and limitations, so it is not unusual for a program to use multiple IPC mechanisms. Other IPC mechanisms include pipes, named pipes, signals, message queueing, semaphores, shared memory, sockets, the Clipboard, and application services.
Industry:Software; Computer
An Apple developer center that provides all the resources needed to develop iPhone applications. Access to this developer center requires an ADC membership. See also user focus.
Industry:Software; Computer
A program that allows you to develop iPhone applications, test them on devices, and distribute them to your customers through the App Store.
Industry:Software; Computer
To translate a range of memory in one address space (physical or virtual) to a range in another address space. The virtual-memory manager accomplishes this by adjusting its VM tables for the kernel and user processes.
Industry:Software; Computer
Interrupt priority level. A means of basic synchronization on uniprocessor systems in traditional BSD systems, set using thesplmacro. Interrupts with lower priority than the current IPL are not acted upon until the IPL is lowered. In many parts of the kernel, changing the IPL in Mac OS X is not useful as a means of synchronization. New use ofsplmacros is discouraged. See also spl macro.
Industry:Software; Computer
A way to ensure the integrity of a message or other data using public key cryptography. To create a digital signature, the signer generates a message digest of the data and then uses a private key to encrypt the digest. The signature includes the encrypted digest and identifies the signer. Anyone wanting to verify the signature uses the signer’s digital certificate, which contains the public key needed to decrypt the digest and specifies the algorithm used to create the digest.
