Module 1 Flashcards
A vocabulary and set of grammatical rules (syntax) for instructing a computer to perform specific
tasks.
Programming Language
reads the whole source code and translates it into a complete machine code program
to perform the required tasks which is output as a new file.

The first-generation languages, or 1GL
are also low-level languages that generally consist of
assembly languages

Java
originally called OAK
Java
a high-level, interpreted, interactive and object-oriented scripting language.
Python
designed
to be highly readable.
Python
processed at runtime by the interpreter.
Python is Interpreted
You can actually sit at a Python prompt and interact with the interpreter
directly to write your programs.
Python is Interactive −
supports Object-Oriented style or technique of programming
that encapsulates code within objects.
Python is Object-Oriented
a great language for the beginner-level programmers
and supports the development of a wide range of applications from simple text processing to WWW
browsers to games.
Python is a Beginner’s Language
who developed python?
Guido van rossum
Python has support for an interactive mode
Interactive Mode
You can add low-level modules to the Python interpreter.
Extendable
fairly easy-to-maintain
Easy-to-maintain
more clearly defined and visible to the eyes.
Easy-to-read
has few keywords, simple structure, and a clearly defined syntax
Easy-to-learn
provides interfaces to all major commercial databases.
Databases
supports GUI applications that can be created and ported to many system
calls, libraries and windows systems, such as Windows MFC, Macintosh, and the X Window system of
Unix.
GUI Programming
provides a better structure and support for large programs than shell scripting.
Scalable
describes a process for planning, creating, testing, and
deploying an information system.
Systems Development Life Cycle
Computer professionals that are in charge of creating applications often have the job title of?
System Analyst
describes fundamental properties of the program’s source code and executable
code, including reliability, robustness, usability, portability, maintainability, efficiency, and readability.
Program quality
how often the results of a program are correct
Reliability
how well a program anticipates problems due to errors (not bugs).
Robustness
the ergonomics of a program
Usability
can be compiled/interpreted and run.
Portability
can be modified by its present or future developers in
order to make improvements or customizations, fix bugs and security holes, or adapt it to new
environments.
Maintainability
measure of system resources a program consumes
Efficiency/performance
ease with which a human reader can comprehend the purpose, control flow, and
operation of source code.
Readability
one method of designing or planning a program.
Pseudocode
display a message asking the user to enter the first age get the
first age from the keyboard display a message asking the user to
enter the second age get the second age from the keyboard.
Input
calculate the answer by adding the two ages together and dividing
by two.
Process
display the answer on the screen pause so the user can see the
answer.
Output
a software application that provides
comprehensive facilities to computer programmers for software development.
integrated development environment (IDE)
used to verify that the inputs, processing, and outputs are working correctly.
Test data
An information system or collection of programs that handles a major task.
Applications
Using test data to check the coded program in a specific language (like C++).
Code checking
The measure of system resources a program consumes.
Efficiency
The phase of a Systems Development Life Cycle where the programmers would be
assigned to write specific programs. life cycle Systems Development Life Cycle: Planning – Analysis –
Design – Implementation – Maintenance
Implementation
IPO
Inputs – Processing – Outputs
The ease with which a program can be modified by its present or future developers.
Maintainability
Using test data to check the design model (usually done in pseudocode)
Model checking
The range of computer hardware and operating system platforms on which the source code of
a program can be compiled/interpreted and run.

a specific language. These steps when properly documented will make the completed program easier for
other programmers to maintain in the future.

means false; thus,
pseudocode means false code.
PSEUDO
is fake
