Macintosh : Computer Hardware Buyers’ Glossary

Apple produces a competing line of computers to the PCs called the Macintosh.

The Mac computer was named after the popular McIntosh variety of apple tree. However, presumably for legal reasons, Apple deliberately misspelled the name as Macintosh. If you correct the spelling to McIntosh (the tree and also a stereo component maker) or Mackintosh (the toffee maker), Mac users will treat you as if you had defecated on the floor, ditto if you abbreviate its name to MAC instead of Mac.

The original Macs used the Motorola 68000 series of CPUs. Then Apple switched to using the IBM (International Business Machines) PowerPC RISC (Reduced Instruction Set Computer) CPU (Central Processing Unit). All the currently manufactured Macintoshes now use Intel CPU s, the same as used in Windows and Linux/Ubuntu machines.

Advantages

• Macs are better designed to be easy to use.
• Everything is designed to work properly together. In the PC (Personal Computer) world everything is created by people who have never met or even talked to each other.
• Virus writers tend to focus on the more numerous PCs (Personal Computers). Viruses are not a problem with the Mac. Spam, of course, is, just as with the PC.

Disadvantages

• The market for Mac software is about 1/10th the size of the PC software market, so you won’t have as many choices of vendor for any particular application, and there are fewer niche utilities.
• Apple tightly controls Mac hardware. This means you will pay considerably more for it than for the equivalent PC hardware. For example, where I live, an iMac with 20-inch monitor, 2.4 GHz Dual core CPU, 2 gig RAM (Random Access Memory), 320 gig hard disk will set you back A roughly corresponding 3 GHz Dual Core PC will set you back about only A Mac Pro with 4 cores, 2.8 GHz, 8 gig RAM, 320 gig disk and 24-inch monitor will set you back . A comparable 4-core 3.16 GHz PC costs Last revised/verified: 2008-08-22
• There is not as much niche add-on hardware available.

Keyboard Layout

The Macintosh keyboard is slightly different from a PC keyboard.
