CD-ROM
Compact disc read only memory. This is a form of digital data storage which is read optically with a laser rather than a magnetic head. A typical
CMOS RAM
Complementary metal oxide semiconductor random access memory. This is a technology for manufacturing random access memory which requires very low levels of power to operate.
COMM Port
Abbreviation for communication port. This is your serial interface connection.
Command
An instruction which you give your operating system. Example: run a particular application or format a floppy disk.
Configuration
The combination of hardware and software that makes up your system and how it is allocated for use.
CRT

Data
The information a system stores and processes.
DC
Direct current. A voltage or current that does not fluctuate periodically with time.
Default Value
A pre programmed value to be used if you fail to set your own.
DIMM
Disk
A spinning platter of magnetic data storage media. If the platter is very stiff it is a hard drive, if it is highly flexible it is a floppy disk, if it is a floppy disk in a hard housing with a shutter it is commonly called a diskette.
