Python Chp. 1 Flashcards
True/False:
Computer science is the study of computers.
False
Computer science is the study of what can be computed.
True/False:
The CPU is the “brain” of the computer.
True
The CPU performs simple arithmetic and logical operations.
True/False:
Secondary memory is also called RAM.
False
The RAM is considered main memory and a HDD or SSD is considered secondary memory.
True/False:
All information that a computer is currently working on is stored in main memory.
True
True/False:
The syntax of a language is its meaning and semantics is its form.
False
The syntax of a language is its form and the semantics is its meaning.
True/False:
A function definition is a sequence of statements that defines a new command.
True
True/False:
A programming environment refers to a place where programmers work.
False
A programming environment is a program designed to help programmers write programs. It usually includes auto-indenting, auto-completion, color syntax highlighting, and interactive development features.
True/False:
A variable is used to give a name to a value so it can be referred to in other places.
True
True/False:
A loop is used to skip over a section of a program.
False
A loop is used to repeat a section of a program.
True/False:
A chaotic function can’t be computed by a computer.
False
A chaotic function can be computed, however the results won’t provide any meaningful pattern.
A mathematical model is called chaotic if very small changes in the input lead to large changes in the result, making them seem random or unpredictable.

a) parentheticals
b) parameters
c) arguments
d) both b and c are correct
d) both b and c are correct
