This document discusses software development and a software development process. It begins by defining software as a collection of computer programs and data that provide instructions for what a computer should do. It then describes different types of software like systems software and application software. The document outlines the typical stages of a software development process including specification, design, coding, testing, and evolution. It provides examples of system failures caused by software bugs. The remainder of the document discusses the contents of a textbook on C programming, outlining chapters that will cover topics like the programming environment, basic building blocks, loops, decisions, functions, arrays, strings, pointers, files and larger programs. It concludes with information on tests, labs, and the paper format for the course

1. Software Development

2. Objectives
 Software development process
 Course revision and paper plan
 Discussion

3. Software
Computer software, or just software, is a collection of
computer programs and related data that provide the
instructions for telling a computer what to do and how to
do it.

4. instructions for telling a computer what to do and how to do
it.
 Types of software:
 Systems software, e.g., device drivers, operating systems, utilities
 Programming software e.g., compiler, linker, text editor
 Application software e.g., web browser, online banking application

5. Software Layered Structure

7. Software Development Process
 A structured set of activities required to develop a
software system
 Specification;
 Design/Coding/Implementation;
 Validation/Testing/Verification; Evolution.
 A software process model is an abstract representation
of a process. It presents a description of a process from
some particular perspective.

13. System Specifications

14. Systems Failures (Bug Reporting)
 “The US banking system collapsed because a bug was found in the banking
protocol (Network World, 1991).”
 “The bug in Intel's Pentium II floating-point division unit in the early nineties
caused a loss of about 475 million US dollars to replace faulty processors, and
severely damaged Intel's reputation as a reliable chip manufacturer (Baier et.
al., 2008).”
 “The software error in baggage handling system postponed the opening of
Denver's airport for 9 months, at a loss of 1.1 million US dollars per day (Baier
et. al., 2008).”
 “A software flaw in the control part of the radiation therapy machineTherac-
25", caused the death of six cancer patients between 1985 and 1987 as they
were exposed to an overdose of radiation (Baier et. al., 2008).”
