'''
Introduction'''
Mac is the dedicated system for Apple Computer. It is the imaging operating system based on UNIX core. Generally it cannot be installed on the normal PC.

Besides, almost all the computer virus is aimed at Windows. As the framework of MAC is different from Windows, it is hardly attacked by virus. MAC OSX has very unique operating system, which has visual icon and man-machine conversation function. Apple Inc can produce computer according to its own technical standard and develop corresponding system, you can see the powerful technology of it. Apple Inc is just like the combination of IBM and Microsoft with both talents of software and hardware.

'''Hardware'''
Apple Inc not only produses its own operating system, it also produces corresponding hardwares, including:

'''Power PC Chip'''
The power PC chip of Mac is RISC chip. Most of PC are using CISC chip.

'''Operating system'''
Operating system of Mac is Mac OS X. It is based on UNIX core system which has improved the stability and performance of system.

'''Appearance''' 　　
The appearance of Mac is transparent so it looks very simple but graceful. The design of iMac G3 is really a creation. It combines the host with display in one, and with the colorful appearance Mac has become very popular all over the world.

'''CPU'''
The exclusive CPU includes Power PC G3, Power PC G4 and Power PC G5. They are developed by IBM, Motorola, and other firms for Mac. Especially Power PC G4, it can make 128-bit operation.
'''
Main Board'''
There are two kinds of main board of Mac. They are the low-end and the high-end. They both have three 64-bit 33MHz PCI slots, two external IEEE 1394 400 Mbps FireWire ports, a built-in 10/100 Base-T network card, a 56K Moderm, and 4 DIMM internal storage slots.

'''RAM, Hard Disc and other units'''
The RAM and hardware of Mac are similar to PC. The RAM is SDRAM of PC133. The hardware is IBM ATA66 and ATA100.

'''Graphics card'''
The two competitors, ATI and NVIDIA, have raged the battle from Desktop to Notebook, and now to Mac. But the leading role of ATI has been replaced by NVIDIA in the Notebook and Mac.

Display
Mac also uses CRT and LCD. IMac series (after iMac G3 all the iMac products use LCD) use CRT, and the kinescope is the Mitsubishi DiamondTron. LCD is mainly used in Power Mac G4 and G5 series.

'''Sound'''
Mac has the buil-in Odyssey sound system developed by Apple Inc and Harman Kardon.

'''CD Driver'''
Mac uses DVD instead of common CD-ROM.

'''Mouse'''
The Apple Pro Mouse of Mac is very pretty with its glass shell.
