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

are two memory areas that Windows needs to manage running programs and
graphical elements.
Task

and to force them to quit if need be. The Task Manager is accessed by pressing

Taskbar
Part of the Windows user interface from which the most important program
functions can be activated and where buttons can be found for all active
applications.
Temporary files
Files that are needed for a short time to save data until the user or system is done
processing it. Temporary files are usually deleted automatically as soon as the
corresponding action or process is ended properly.
Temporary paging file
A paging file that is only created by Windows when needed. This file has a
different size depending on the current needs of the system and is usually stored
at a different location each time it is created (see permanent paging file).
