Python- Chapter 1

Central Processing Unit
the heart of any computer. Runs the software that we write; also called "CPU" or "the processor"
to translate a program written in a high-level language into a low-level language all at once, in preparation for later execution
high-level language
a programming language like Python that is designed to be easy for humans to read and write
interactive mode
a way of using Python interpreters by typing commands and expressions at the prompt
to execute a program in a high-level language by translating it one line at a time
low-level language
a programming language that is designed to be easy for a computer to execute; also called "machine code" or "assembly language"
machine code
the lowest-level language for software, which is the language that is directly executed by the central processing unit (CPU)
to examine a program and analyze the syntactic structure
a property of a program that can run on more than one kind of computer
print statement
an instruction that causes the Python interpreter to display a value on the screen
problem solving
the process of formulating a problem, finding a solution, and expressing the solution
a set of instructions that specifies a computation
when a program displays a message and pauses for the user to type some input to the program
secondary memory
stores programs and data and retains its information even when the power is turned off. Generally slower than main memory. EX: USB
the meaning of a program
semantic error
an error in a program that makes it do something other than what the programmer intended
source code
a program in a high-level language
