|
|
|
What is object code?
|
The translated machine language instructions that the compiler stores in an object file.
|
|
|
What is a compiler?
|
A program that translates source code instruction into machine language instruction and stores those instructions as object code into object file.
|
|
|
What is syntax?
|
Rules that must be followed when constructing a program. It dictates how key words and operators may be used, and where punctuation symbols must appear.
|
|
|
What is does an interpreter do?
|
It translates ONE source statement at a time into executable statements. Each statement is executed immediately after translation. Good for finding errors.

What is an algorithm?
|

|
What is a higher level language?
|
A language, like C++, that has English-like commands, arabic numbers, is machine independent, is less efficient than machine language, and uses symbolic locations.
|
|
|
What is a preprocessor and what does it do?
|
It is a program that reads source code, looking for lines beginning with the # symbol. These lines have commands that cause the preprocessor to to modify the source code in some way. It basically sets up source code for the compiler.

What is RAM?
|
(Random Access Memory) It is the computer's main memory. It holds the sequences of of instructions in the programs that are running and the data those programs are using. It is for temporary storage.

|
What is a high-level language?
|
A programming language that is closer to the level of human-readability, like C++. Mostly words.
|
|
|
What is a low-level language?
|
A programming language that is closer to machine language.
|
|
|
What is pseudocode?
|
A cross between human language and a programming language used by programmers to think through and plan the steps of a program they will create.
|
|
|
What is machine language?
|
It is language, made up of binary numbers, that can be understood by a CPU.
|
|
|
What is a loader program?
|
Loader program is an operating system utility that performs the functions of a linker program and then immediately schedules the resulting executable program for action in the form of a memory image, without necessarily saving the program as an executable file. Loader programs are useful for prototyping, testing, and one-off applications.

|
What is a utility program?
|
Utility program, or utility, is a type of computer programs that support using the computer, an application or a development environment. Utility programs include file management, searching for files, comparing file contents as well as performing diagnostic routines.
