Client-side scripting – Method

Client-side scripts are often embedded within an HTML document (hence known as an “embedded script”), but they may also be contained in a separate file, which is referenced by the document (or documents) that use it (hence known as an “external script”). Upon request, the necessary files are sent to the user’s computer by the [...]

Motorola ROKR E6 – Introduction

It was released in the China on November 14, 2006, and subsequently worldwide on December 4, 2006. The ROKR E6 is a direct descendant of the E680 and the MING, sharing the same Montavista Linux operating system, Intel XScale [...]

Disk cloning – Operating environment

A disk cloning program needs to be able to read even protected operating system files on the source disk, and must guarantee that the system is in a consistent state at the time of reading. It must also overwrite any operating system already present on the destination disk. To simplify these tasks, most disk cloning [...]

Device file – Implementation

By definition, device nodes correspond to resources that an operating-system kernel has already allocated. Unix identified those resources by a ”major number” and a ”minor number”, both stored as part of the structure of a node. The assignment of these numbers occurs uniquely in different operating systems and on different computer platforms. Generally, the major [...]

Microkernel – Introduction

microkernel is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system. These mechanisms include low-level address space management, thread management, and inter-process communication(I.P.C). As an operating system design approach, microkernels permit typical operating system services, such as device drivers, protocol stacks, file systems and user interface code, to [...]

File Allocation Table – Introduction

File Allocation Table (FAT) is a computer file system architecture now widely used on many computer systems and most memory cards, such as those used with digital cameras. FAT file systems are commonly found on floppy disks, flash memory cards, digital cameras, and many other portable devices because of their relative simplicity. Performance of FAT [...]

Concurrent Versions System – Features

CVS uses a client–server architecture: a server stores the current version(s) of a project and its history, and clients connect to the server in order to “check out” a complete copy of the project, work on this copy and then later “check in” their changes. Typically, the client and server connect over a LAN or [...]

FreeVMS – Introduction

The latest version is 0.3.15. It consists of a kernel (planned to be POSIX-compliant) and a DCL command-line interpreter. Adapted from [...]

Verdana – Legal restrictions and prevalence

Released in 1996, Verdana was bundled with subsequent versions of the Windows operating system, as well as their Office and Internet Explorer software on both Windows and Mac OS. In addition, it was long available for download from Microsoft’s web site allowing it to be used by any system supporting TrueType fonts. The downloadable file [...]

ProvideX – Introduction

ProvideX is a computer language and development environment derived from Business Basic (a business oriented derivative of BASIC) in the mid-1980s. ProvideX is available on several operating systems (Unix/Linux/Windows/Mac OS X) and includes not only the programming language but also file system, presentation layer interface, and other components. The language is primarily designed for use [...]

Control-C – Introduction

Control-C is a common computer command. It is generated by pressing the key while holding down the key on a computer keyboard. The equivalent key combinations on Mac OS computers is Command-C. In graphical user interface environments that use the control key to control the active program, control-C is often used to copy highlighted text [...]

Netpbm – Introduction

Netpbm is an open source package of graphics programs and a programming library, used mainly in the Unix world. It is a highly portable package, working under many Unix platforms, Windows, Mac OS X, VMS, Amiga OS and others and is included in all major open source Unix-like operating system distributions. Adapted from the Wikipedia [...]

History of the graphical user interface – The 80s: Early commercial developments

Apple Lisa and Macintosh (and later, the Apple IIgs) Beginning in 1979, started by Steve Jobs and led by Jef Raskin, the Lisa and Macintosh teams at Apple Computer (which included former members of the Xerox PARC group) continued to develop such ideas. The Macintosh, released in 1984, was the first commercially successful product to [...]
