For some time in the early 1990s, the Mac was a primary client on the rapidly expanding Internet.

For instance, Tomás Mac Curtain, the Mayor of Cork, was assassinated in March 1920 by local RIC men and the massacre of 13 civilians at Croke Park on Bloody Sunday was also carried out by the RIC although a small detachment of Auxiliaries were also present.

For instance, the County Longford IRA under Seán Mac Eoin carried out a number of well planned ambushes and successfully defended the village of Ballinalee against Black and Tan reprisals in a three-hour gun battle.

For example, a CD-ROM may contain an alternative file system descriptor in this area, as it is often used by Hybrid CDs to offer Mac OS-specific content.

For most users, the most noticeable changes are: the disk space that the operating system frees up after a clean install compared to Mac OS X 10. 5 Leopard, a more responsive Finder rewritten in Cocoa, faster Time Machine backups, more reliable and user friendly disk ejects, a more powerful version of the Preview application, as well as a faster Safari web browser.

For backwards compatibility Apple added the " Blue Box " to the Macintosh, allowing existing Mac applications to be run in a self-contained cooperative multitasking environment.

For those who desire stronger Mac OS / CLIÉ integration, the product Missing Sync made by the company Mark / Space is also available.

For example, Mac OS X uses a feature called Exposé which allows the user to temporarily see all windows belonging to a particular application.

For much of the decade, System 7, Mac OS 8, and Mac OS 9 would be in consumer Macintoshes and its clones.

For Mac OS X, the Mac GPG project provides a number of Aqua front-ends for OS integration of encryption and key management as well as GnuPG installations via Installer packages.

For hardware accelerated 3D and 2D acceleration on Linux, Mac OS X and DOS, AllegroGL and OpenLayer are available.

For non-PostScript ( raster ) printers, the final raster image was produced by the computer and sent to the printer, which meant dot-matrix printers on the Mac platform exclusively used raster (" graphics ") printing mode.

For near-letter-quality output, the Mac would simply double the resolution used by the printer, to 144 dpi, and use a screen font twice the point size desired.

For example, one could install Linux, BSD, Mac OS X, Microsoft Windows or other operating systems on different partitions of the same hard disk and have a choice of booting into any compatible operating system at power-up.

For example, consider the references to the use of a Dobro guitar on songs like " The Ballad of Curtis Loew " by Lynyrd Skynyrd, " Valium Waltz " by the Old 97's, " When Papa Played the Dobro " by Johnny Cash on the Ride This Train album, or " Gold Dust Woman ", a song by Fleetwood Mac from the album Rumours which features a a Dobro.

For example, a cross-platform application may run on Microsoft Windows on the x86 architecture, Linux on the x86 architecture and Mac OS X on either the PowerPC or x86 based Apple Macintosh systems.

For mobile applications, browser plugins are used for Windows and Mac based devices, and Android has built-in support for Java.

For example, Mozilla Firefox, an open-source web browser, is available on Microsoft Windows, Mac OS X ( both PowerPC and x86 through something Apple calls a Universal binary ), and Linux on multiple computer architectures.

For example, applications developed for Mac OS X and GNOME are supposed to place the most important button on the right-hand side of a window or dialog, whereas Microsoft Windows and KDE have the opposite convention.

For programmers, the fourth Inside Macintosh volume detailed how to use HFS and the rest of the Mac Plus's new system software.

For the role of Dr. Emilio Lizardo, the studio wanted to cast an unknown actor but Mac Rauch had written the role with John Lithgow in mind.

For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it.

For example, POSIX and OS abstraction layers provide commonalities that reduce porting costs.

For the first time, OS / 2 was able to run more than one DOS application at a time.

For example, many bank installations, especially Automated Teller Machines, run OS / 2 with a customized user interface ; French SNCF national railways used OS / 2 1. x in thousands of ticket selling machines.

For example, the comp. os. ms-windows Usenet hierarchy has a group reserved solely for advocacy — the Guide to the Windows newsgroups exhorts Usenet posters not to " get involved in arguments about Windows vs. OS / 2 vs. Macintosh vs. NeXTSTEP except in the comp. os. ms-windows. advocacy group.

For example, some early Palm OS PDAs came only with Palm Desktop, while later Palm PDAs — such as the Treo 650 — have the ability to sync to Palm Desktop or Microsoft Outlook.

For many operating systems, Python is a standard component ; it ships with most Linux distributions, FreeBSD, NetBSD, OpenBSD and with OS X and can be used from the terminal.

For this reason it can be problematic when an interrupt handler calls an OS function while the application is in the act of also doing so.

For instance, IBM OS / 390, now z / OS, qualifies as a " Unix " despite having no code in common.

For example, Solaris Zones supports multiple guest OSes running under the same OS ( such as Solaris 10 ).

For example, IBM's z / OS has 3 modes ( virtual-virtual, virtual-real and virtual-fixed ).

# For monatomic ions, the OS is the same as the charge of the ion.

For example, S < sup > 2 -</ sup > has an OS of-2, whereas Li < sup >+</ sup > has an OS of + 1.

For example, on-line recognition, such as that used for gestures in the Penpoint OS or the Tablet PC can tell whether a horizontal mark was drawn right-to-left, or left-to-right.

For example, the term is used to describe systems such as verlan and louchébem, which retain French syntax and apply transformations only to individual words ( and often only to a certain subset of words, such as nouns, or semantic content words ).

For example, autopilot systems that are prolific today were started to help bomber planes fly steadily enough to hit precision targets from high altitudes.

For a time, the combined company retained the Burroughs processors as the A and V systems lines.

For example, an information systems specialist will view computing somewhat differently from a software engineer.

For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

For instance, NASA has extremely rigorous software testing procedures for many operating systems and communication functions.

For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems.

For example, kinship and leadership function both as symbolic systems and as social institutions.

For very large systems, the relative total energies can be compared using molecular mechanics.

For π-electron systems, this was the Hückel method proposed by Erich Hückel, and for all valence electron systems, the extended Hückel method proposed by Roald Hoffmann.

For example, the conservation of energy follows from the time-invariance of physical systems, and the fact that physical systems behave the same regardless of how they are oriented in space gives rise to the conservation of angular momentum.

For some distributed parameter systems the vectors may be infinite-dimensional ( typically functions ).

For simplicity, the following descriptions focus on continuous-time and discrete-time linear systems.

For example, there is a hard disk, from which most operating systems run and on which most store their files.

For instance, on newer MS Windows computers, the older FAT-type file systems of MS-DOS and old versions of Windows are supported, in addition to the NTFS file system that is the normal file system for recent versions of Windows.

For continuous, frequent or prolonged intravenous chemotherapy administration, various systems may be surgically inserted into the vasculature to maintain access.

For example, Burris has reviewed sociological publications and used the theories of Weber and Bourdieu to describe academic caste systems.

For this reason it is not hard to port games between these systems.

For embedded systems, the highest performance levels are often not needed or desired due to the power consumption requirements.

For a while hybrid cable / electric systems operated, for example in Chicago where electric cars had to be pulled by grip cars through the loop area, due to the lack of trolley wires there.

For microscopic, atomic-level systems like a molecule, angular momentum can only have specific discrete values given by
