MAC Computers


Macintosh, commonly known as Mac, is a brand name which covers several lines of personal computers designed, developed, and marketed by Apple Inc. Named after the McIntosh variety of apple, the original Macintosh was released on January 24, 1984. It used a graphical user interface (GUI) and mouse instead of the then-standard command line interface. The current range of Macs varies from Apple's entry level Mac mini desktop, to a mid-range server, the Xserve. Mac systems are mainly targeted at the home, education, and creative professional markets. Production of the Mac is based upon a vertical integration model in that Apple facilitates all aspects of its hardware and creates its own operating system that is pre-installed on all Macs. This is in contrast to most IBM compatible PCs, where one vendor provides the operating system and multiple vendors create the hardware. In both cases, the hardware can run other operating systems; modern Macs, like other PCs, are capable of running operating systems such as Linux, FreeBSD, Windows, etc.
Original Macintosh computers used the Motorola 68k family of microprocessors, but later models switched to Motorola and IBM's PowerPC range of CPUs in 1994. Apple began a transition from the PowerPC line to Intel's x86 architecture in 2006, which for the first time allowed Macs to run native operating system binaries for the x86 architecture. Current Macs use the Intel Core 2 and Intel Xeon 5100 series microprocessors. All current Mac models come pre-installed with a native version of the latest Mac OS X, which is currently at version 10.4.10 and is commonly referred to by its code name of "Tiger". Apple has announced that Mac OS X v10.5, codenamed "Leopard", is set to be released in October of 2007.

PC Computers!!!


A personal computer (PC) is a computer whose price, size, and capabilities make it useful for individuals. We may never know who coined the phrase with the intent of a small affordable computing device but John W. Mauchly described such a device in a November 3, 1962 New York Times article entitled "Pocket Computer may replace Shopping List". Six years later a manufacturer took a risk at referring to their product this way when Hewlett Packard advertised their "Powerful Computing Genie" as "The New Hewlett Packard 9100A personal computer"[1]. This advertisement was too extreme for the target audience and replaced with a much drier ad for the HP 9100A programmable calculator. [2] [3] [4] During the next 7 years the phrase had gained usage so when //Byte// magazine, published its first edition it referred to its readers as being in the "personal computing field"[5] while Creative Computing defined the personal computer as a "non-(time)shared system containing sufficient processing power and storage capabilities to satisfy the needs of an individual user." [6] Two years later when the 1977 Trinity of preassembled small computers hit the markets, the Apple II[7] and the PET 2001[8] were advertised as 'personal computers' while the TRS-80 was a microcomputer used for household tasks including "personal financial management". By 1979 over half a million microcomputers were sold and the youth of the day had a new concept of the personal computer. [9]
Personal computers can be categorized by size and portability:
