one bit at a time to another device. This method allows for

delays of any length between characters.

AUTOEXEC.BAT file

A special kind of batch file MS-DOS executes automatically

each time you turn on or reset the computer.

Backlighting

The internal fluorescent illumination of the computer’s LCD

screen. LCD screens that are not backlit are not legible without

an external source of light.

Backlight period

The length of time your LCD screen stays illuminated in the

absence of keyboard activity. To restore backlighting to your

screen after the backlight period has elapsed, press any key. To

change the backlight period, run the SETLCD program (see
Chapter 2).

Backup

A copy of a program, data file, or disk, kept in case the original

is damaged or lost.

Batch file

A text file containing one or more MS-DOS commands, each

stored on a separate line. You use batch files to automate

MS-DOS operations. When you type the name of the batch file

(with or without its .BAT extension), each command in the file

executes in sequence.
