Address (of a cell): unique location in main memory for each cell
Algorithm: step-by-step problem-solving process in which a solution is arrived at in a finite
amount of time
Assembler: program that translates a program written in assembly language into an equivalent
program in machine language
American Standard Code for Information Interchange (ASCII): most commonly used
encoding scheme used on personal computers; the ASCII data set uses seven bits to represent 128
characters, numbered from 0 to 127
Analog signals: continuous wave forms used to represent such things as sound
Application programs: software programs that perform a specific task
Arithmetic logic unit (ALU): hardware component of a computer that carries out all arithmetic
and logical operations
Binary (base 2): the number system that a computer uses
Binary code (binary number): sequence of 0s and 1s
Binary digit (bit): the digit 0 or 1
Build (Make): command that does the linking on C++ Builder; on CodeWarrior, use Make
Build (Rebuild): command that does the linking on Visual C++ and Visual Studio .NET
Byte: sequence of eight bits
Central processing unit (CPU): brain of the computer and the single most expensive piece of
hardware in a personal computer
Compiler: program that translates instructions written in a high-level language into machine code
Control unit (CU): hardware component of the computer that fetches and decodes instructions,
controls the flow of information in and out of main memory, and controls operations of the CPU’s
internal components
Decimal system (base 10): number system we use in daily life.
Digital signals: represent information with a sequence of 0s and 1s
High-level languages: programming languages that are similar to natural speaking languages
Input devices: devices that feed data and programs into computers
Instruction register (IR): holds the instruction that is currently being executed
Kilobyte (KB): 1024, or 210 bytes
Library: place where prewritten code resides
Linker: program that combines the object program with other programs in the library, and used in
the program to create the executable code
Loader: program that loads an executable program into main memory
Machine language: language of a computer; a sequence of 0s and 1s
Main memory: memory directly connected to the CPU
Memory cells: ordered sequence of cells in main memory
Mnemonic: instruction that is in an easy-to-remember form
Object program: machine language version of the high-level language program
Object-oriented design (OOD): programming methodology that identifies components called
objects, which form the basis of the solution to a problem
Object-oriented programming (OOP): programming language that implements object-oriented
design (OOD)
Operating system: monitors the overall activity of the computer and provides services
Preprocessor: program that processes statements in a C++ program that begin with the symbol #
Program counter (PC): points to the next instruction to be executed
Secondary storage: device that stores information permanently
Source code (source program): program written in a high-level language
Structured design (top-down design, stepwise refinement, modular programming): dividing
a problem into smaller subproblems
System programs: programs that control the computer
