Title: An overview of the Mac CPU

By: Jay Moncliff

There has been a heated debate in the world of operating systems ever since two versions which are highly effective have been launched. This debate has been going on for ages. The two entities which make up this debate are Windows operated PC and Macintosh or Mac CPU operated systems. Apple computers have used the Mac CPU and its users have been satisfied with the performance of the computer using this operating system and the same can be said for Window enabled PCs as well. Both the systems have their pros and cons but in the long run Mac CPU does seem to hold an edge over its major competitor.

The basic difference in a Mac CPU is that it runs on Mac OS. It is the trademark symbol of GUI based OS made by Apple Inc. The Macintosh is said to have popularized the concept of GUI (graphical user interface). Apple did not really use an in-depth OS in Macintosh initial years. It did so to make the user-friendly machine and to make id different from other competitive operating systems like MS-DOS as they were seen as unknowable and technically daring. Much of these earlier software were placed in ROM. Updates were free and without any charge by the dealers of Apple mainly on a floppy disk. The increase in disk capacity gradually decreased the requirement for repair of advanced GUI in ROM. Ultimately Apple discovered cloning and saw them as distinct revenue producing products starting with their earlier System 7 as well as 7.5 versions and finally came up Mac OS 7.6 in the year 1997.

The first of the versions of Mac OS were friendly alongwith Motorola 68000 Macintoshes. But the introduction of computers with the PowerPC, the need to upgrade the OS to support such kind of architecture was done. The newer lot of Mac CPU uses more advanced operating systems like Mac OS X. The Mac Operating System X has incorporated Unix style of memory management as well as added the pre-emptive tasking to the platform of Mac. It is adopted on Mach kernel as well as BSD of UNIX. These have been jelled in NeXTSTEP which is a task based operating system. It has been developed by the NeXT founded by Steve Job. The addition of a new memory management allows running of a number of programs simultaneously. This has almost eliminated the chances of crashing of a program into another. It is the second Macintosh OS to include command line. However, new features place more demands on the system resources. The Mac OS X merely officially supports PowerPC G3 as well as some other newer processors. There are even more requirements now like the need of in-built USB and FireWire which is essential for modern day computing. After the incorporation of all of this, the users still find that G3 is a bit slower working on this.

All in all, the Mac CPU operated offer a user friendly and fast computing experience with the least of security crashes. This is a reason why most Mac users do not settle for anything else.
