7.Introduction
In early 1980s, C++ developed by Bjarne Stroustrup
C is a structured language while C++ is Object oriented
Object Oriented Programming (OOP) technique enable programmer to write quality code

8.What Is a Computer?
Computer
Performs computations and makes logical decisions
Millions or billions of times faster than human beings
Computer programs
Sets of instructions for which computer processes data
Hardware
Physical devices of computer system
Software
Programs that run on computers

9.Computer Organization
Six logical units of computer system
Input unit
Mouse, keyboard
Output unit
Printer, monitor, audio speakers
Memory unit
Retains input and processed information
Arithmetic and logic unit (ALU)
Performs calculations
Central processing unit (CPU)
Supervises operation of other devices
Secondary storage unit
Hard drives, floppy drives

10.Early Operating Systems
Batch processing
One job (task) at a time
Operating systems
Developed to make computers more convenient to use
Made transitions between jobs easier
More throughput
Multiprogramming
“Simultaneous” jobs
Timesharing operating systems

11.Personal, Distributed and Client/Server Computing
Personal computing
Computers for personal use
Distributed computing
Networked computers
Computing performed among several computers
Client/server computing
Servers offer common store of programs and data
Clients access programs and data from server

12.The Internet and the World  Wide Web
Internet
Developed more than four decades ago with DOD funding
Originally for connecting few main computer systems
Now accessible by over a billion computers
World Wide Web (WWW)
Allows for locating/viewing multimedia-based documents

13.Machine Languages, Assembly Languages and High-Level Languages
Machine language
“Natural language” of computer component
Machine dependent
Assembly language
English-like abbreviations represent computer operations
Translator programs (assemblers) convert to machine language
High-level language
Allows for writing more “English-like” instructions
Contains commonly used mathematical operations
Compiler converts to machine language
Interpreter
Execute high-level language programs without compilation

14.History of C and C++
C++ evolved from C, which evolved from BCPL and B
C
Developed at Bell Labs
Popularized as the language of the UNIX operating system
C++
Deveoped by Bjarne Stroustrup
Provides object-oriented programming capabilities
Hybrid language
Objects
Reusable software components that model real-world items
Attributes and behaviors

15.Object Oriented Programming
Classes
Data Members
Member Functions
Member Access specifiers
Objects
