Keyboard – This is a component that comes in direct contact for you with your PC. The
mechanism of keyboard converts a key cap’ s movement into a signal sent to the
computer. The most common key mechanism are “ capacitate ” and “ hard contact ”.
Capacitate keyboard has a spring that causes the plastic and the metal plunger to move
nearer to two pads that have large plates (plated in tin, nickel, and copper). These pads
are connected to the keyboard’ s printed circuit board. Hard contact keyboard causes
the key cap to collapse a foam rubber dome that presses against a sheet of plastic on
the bottom of which is metallic area connected to the rest of the keyboard’ s
circuit board.
LDCM (LANDesk Client Manager) – With the help of LDCM, PCs that are either stand-
alone or on a network can not escape the control of a system administrator. Alerts will
be sent to the user if an abnormal condition is encountered in a PC. It allows the
administrator to give each PC a thorough check-up. Additionally, this feature is
available to multiple OS’ s on the market today. LDCM Key Features

Mouse – The keyboard is a barrier to learn how to use a computer. Xerox Corporation
first developed the concept of a pointing device, something a computer user could move
with his or her hand, causing a corresponding move on screen. Because of its size and
tail like cable, the device was named for the mouse. Apple Computer made the mouse
a standard feature of its Macintosh computers, and with the popularity of Windows, a
mouse is becoming standard equipment on all PCs, as well. The “ Trackball ” have
survived more awkward methods of navigating with the keyboard. “ Digitizing tablets ”
are popular with architects and engineers who must translate precise movements of a
pen into lines on the screen. “ Touch screens “, on which you press either your finger
and a special light pen to control the software, are too tiring to use for any length of time.
MMX
– CPU’ s with MMX
technology are optimized to run multimedia application,
and therefore, offer faster multimedia playback than standard CPUs. However, when
manufacturers introduce any new hardware technology, the software makers need to
catch up. At this time of compilation, most applications can’ t yet take advantage of
MMX
capabilities.
