    There are a lot of terms used to describe
    computers. Most of these words imply the size, expected use or
    capability of the computer. While the term computer can apply to
    virtually any device that has a microprocessor in it, most people think
    of a computer as a device that receives input from the user through a
    mouse or keyboard, processes it in some fashion and displays the result
    on a screen.



    * PC - The personal computer
    (PC) defines a computer designed for general use by a single person.
    While a Mac is a PC, most people relate the term with systems that run
    the Windows operating system. PCs were first known as microcomputers
    because they were a complete computer but built on a smaller scale than
    the huge systems in use by most businesses.



    * Desktop - A PC that is not
    designed for portability. The expectation with desktop systems are that
    you will set the computer up in a permanent location. Most desktops
    offer more power, storage and versatility for less cost than their
    portable brethren.



    * Laptop - Also called
    notebookslaptops are portable computers that integrate the display,
    keyboard, a pointing device or trackball, processor, memory and hard
    drive all in a battery-operated package slightly larger than an average
    hardcover book.



    * Palmtop- More commonly known
    as Personal Digital Assistants (PDAs), palmtops are tightly integrated
    computers that often use flash memory instead of a hard drive for
    storage. These computers usually do not have keyboards but rely on
    touchscreen technology for user input. Palmtops are typically smaller
    than a paperback novel, very lightweight with a reasonable battery
    life. A slightly larger and heavier version of the palmtop is the
    handheld computer.



    * Workstation - A desktop
    computer that has a more powerful processor, additional memory and
    enhanced capabilities for performing a special group of task, such as
    3D Graphics or game development.



    * Server - A computer that has
    been optimized to provide services to other computers over a network.
    Servers usually have powerful processors, lots of memory and large hard
    drives.



    * Mainframe - In the early days
    of computing, mainframes were huge computers that could fill an entire
    room or even a whole floor! As the size of computers has diminished
    while the power has increased, the term mainframe has fallen out of use
    in favor of enterprise server. You'll still hear the term used,
    particularly in large companies to describe the huge machines
    processing millions of transactions every day.



    * Minicomputer - Another term
    rarely used anymore, minicomputers fall in between microcomputers (PCs)
    and mainframes (enterprise servers). Minicomputers are normally
    referred to as mid-range servers now.



    * Supercomputer - This type of
    computer usually costs hundreds of thousands or even millions of
    dollars. Although some supercomputers are single computer systems, most
    are comprised of multiple high performance computers working in
    parallel as a single system. The best known supercomputers are built by
    Cray Supercomputers.



    * Wearable - The latest trend
    in computing is wearable computers. Essentially, common computer
    applications (e-mail, database, multimedia, calendar/scheduler) are
    integrated into watches, cell phones, visors and even clothing!
