Glossary
appearance of the contents of the screen and the greater the
area on the screen (“screen real estate”). In principle, the
resolution of a graphics card depends on the amount of
graphics memory, the refresh rate and the color depth. The
higher the resolution, the lower the refresh rate and color
depth. Graphics cards with 2 MB of memory can only display
256 colors at 1280 x 1024 pixels, while 16.7 million colors
can be displayed at a resolution of 800 x 600.
Resources
The totality of all peripheral devices, memory and data that
can be accessed from a computer or over a network
connection.
Restart
Starting the computer again after it has crashed or has been
shut down manually. Also required when installing some
kinds of software or hardware.
Serial port
A port through which data is transmitted bit for bit. Serial
ports on the PC are based on the RS-232 standard. The serial
ports of a computer are also called COM ports, or
communication ports. These are normally used to connect a
mouse, a nullmodem cable and/or a modem to the computer.
Especially when connecting a modem, a COM port with a
special module should be used, UART with FIFO, to allow
higher transmission rates than with standard ports.
System file
Especially important files that are used by the operating
system to store important information and settings. In the case
of DOS, these are Config.sys, Autoexec.bat, Command.com,
IO.sys and MSDOS.sys, for example.
System resources
Under Windows, system resources refers to the user and GDI
subsystems. These are two memory areas that Windows needs
to manage running programs and graphical elements.
