letter quality printer: See daisy wheel printer.
line feed: Act of advancing to the next line.
line number: A number that tells the computer the order in which to carry out the instructions
in a BASIC program.
LISP: A programming language.
LIST: An Applesoft BASIC command that lets you see the program in memory.
load: To put data or programs into the computer from a disk.
Logo: A computer language that encourages learning through discovery. Easy and fun to learn,
but powerful enough for serious application programming.
machine language: The language of ones and zeros that is the only language the computer
understands. All other languages, like BASIC, have to be translated into this binary code
before the computer can understand them.
main circuit board: A large circuit board that holds RAM, ROM, the microprocessor,
custom-integrated circuits, and other components that make the computer a computer.
main memory: See random access memory.
mainframe computer: A computer with far greater processing power and memory capacity than a
personal computer, but harder to pay for and carry from room to room.
mass storage device: A device, like the Apple ProFile, that can store the equivalent of dozens
of floppy disks.
memory: Integrated circuits (chips) that store instructions for the microprocessor (the brain)
of the computer. There are two kinds of memory: temporary memory (called RAM), and permanent
memory (called ROM). The contents of random-access memory disappears when you turn off the
power; the contents of read-only memory do not.
menu: A list of choices.
microprocessor: The brain of the computer. The Apple IIe has a 65C02, eight-bit
microprocessor.
modem: Short for MOdulator/DEModulator. A device that links your computer to other computers
and information services over telephone lines.
Modula-2: A programming language.
monitor: It looks like a TV, but it doesn't have channels. It displays instructions from the
program to you and shows what you've typed into memory.
monochrome monitor: A black and white, amber and black, or green and black monitor.
mouse: A pointing device that makes it easy to draw pictures, select from lists, and move
things around the screen.
mouse button: The button on top of the mouse. You press it to select from menus or when you
want to move items around on the screen.
