Client
This refers to a computer that uses a shared network resource provided by a server.
An application interface developed to enable Windows application
programs to access hardware devices at a very high speed. Since
the operating speed of graphics, memory and sound cards must be
very fast to provide high quality video and sound for games, Direct
X enables faster control and interaction between applications and
hardware devices. By using Direct X, the multimedia performance
of Windows has been hugely improved.
Driver
DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory)
Software that interacts between the hardware and the operating
system. An operating system knows the hardware information
and controls the hardware. In general, a driver is supplied with the
corresponding hardware device.
D-sub (D-subminiature)
DRAM is a memory type whose cells consist of a capacitor and
transistor manufactured at a low price. SDRAM is a memory type
whose performance has been improved by synchronizing the clock
with the external CPU clock. DDR SDRAM is a memory type whose
performance has been improved by doubling the operating speed
of the SDRAM and is widely used nowadays. This computer uses
DDR SDRAM.
