Реферат: Apple Vs The World A Comparison Of
Linux is an operating system that is not like any other. Linux is an operating system that was derived from a more advanced business operating system called UNIX. A man named Linus Torvalds, a Finish student who was doing personal research on operating systems, created Linux and something that is called Open Source code distribution. Open Source means that the source code or code used in a software-coding program to create Linux is readily available and legal for you to add on to and submit. Another oddity of Linux is that it does not have just one manufacturer. Numerous companies including Red Hat, Mandrake, Suse, Corel Linux, Slackware, and Storm have distributed Linux. According to www.Linux.com there are just fewer than twenty different releases of Linux by just as many companies.
Linux has a very similar look to Windows but is more advanced with a system command window and a desktop that is fully customizable with many different looks. Unfortunately, Linux does not have the support of software developers just yet. The lack of software is one of the main reasons Linux hasn?t exploded onto the OS market. Linux is capable of many different functions including being used in place of a Windows NT server with the appropriate software, used as a high end computer programming tool, and/or can be scaled up to handle heavy computing loads of many scientific and engineering programs.
The last operating system that will be discussed is the Apple operating system known as OS. OS has the same type of source code of that of Linux; Apple has made the OS source code available through Open Source code distribution. OS is similar to that of its PC cousin?s operating systems by having a similar user interface as that of Windows and Linux, but with some noticeable differences. OS has a similar programs tray like that of windows only it is more colorful and bright. OS is said to be very user friendly and does not belittle even the most advanced users. OS was created to be a user a strong operating system that can second as a graphical design and editing tool.
OS is constructed in a building block type manor. The base of the building block is the core of the operating system, which is called Darwin. Apple decided to call it Darwin because they describe Darwin as being the next evolution in operation systems. Darwin?s main function is to run the computer and manage the memory and programs efficiently. The next step up from Darwin is the graphical standards for Mac; Quartz, two dimensional rendering software, OpenGL , an industry standard in three dimensional solid or line modeling, and QuickTime, Apple?s own digital video rendering software. The next step up in the tower is Classic, Carbon and Cocoa. To put it quite simply, Classic is for the original Mac users who are not ready to move on, Carbon is a simpler but more crash resistant environment than that of Classic, and Cocoa is a high end computer programming interface for those interested in writing programs.
Comparison
The lines of operating system superiority are very blurry. Each operating system has it?s own distinct advantages and disadvantages. OS for example is a beautifully crafted system that does not support a great deal of popular software and hardware. Linux is the same way, but runs on a PC and does support the hardware. Windows on the other hand tends to crash quite a bit while running most anything without hardware or software conflictions. OS does, however, have a very advanced memory allocation system, something Windows has not fully mastered, although Linux has. Windows and Linux, on the other hand, supports 3D hardware support in advanced gaming and CAD called Direct3D, OS does not. Linux is constantly being updated and changed because of its Open Source code distribution, something Apple is trying, but Microsoft is still skeptical to do.
Affordability and Cost
When purchasing a computer, the first thing the consumer usually looks for is a brand name. For reference, Dell Computer Corporation provided all prices and products for the PCs. Apple, of course, provided all their own product prices and options. Because Apple has two models for there computers, we started with the smaller, low-end fanless, computer called the G4 Cube. Going to the Apple site I built a G4 Cube with these components.
? 450MHz G4 Processor
? 20 Gigabyte Hard Drive
? RAGE 128 Pro card ? 16MB SDRAM (video card)
? DVD-ROM
? 128MB SDRAM (RAM)
? 56k Modem
? Ethernet card
? 17? Monitor (extra)
? 3yr Warranty (extra)
The price of the little eight-inch G4 Cube is $2697.00.
A comparable Dell computer, the Dell Dimension L was created as a comparison.
? 566MHz Pentium Celeron Processor
? 20 Gigabyte Hard Drive
? Intel AGP Graphics card
? 12x DVD-ROM
? 128MB SDRAM
? 56k Modem
? Ethernet card
? 15?monitor (standard)
? 3yr Warranty
The price of the Dell Dimension L was only $1498.00.
