Examples of Cheating ^ Turning in someone else's work, in whole or in part, as your own(with or without his/her knowledge) ^ Turning in a completely duplicated assignment is a flagrantoffense ^ Allowing another student to turn in your work as his/her own ^ Several people writing one assignment and turning in multiplecopies, all represented (implicitly or explicitly) as individualwork

Examples of Not Cheating ^ Turning in work done alone or with the help of the course's TAs. ^ Submitting one assignment for a group of students if groupwork is explicitly permitted (or required) ^ Getting or giving help about using the computers ^ Getting or giving help about solving minor syntax errors^ Penalties for cheating can be an 'F' in the course or worse.

Computer Organization  Six logical units in every computer: ^ Input unit^ ^ Obtains information from input devices (keyboard, mouse) ^ Output unit^ ^ Outputs information (to screen, to printer, to control other devices) ^ Memory unit^ ^ Rapid access, low capacity, stores input information ^ Arithmetic and logic unit (ALU)^ ^ Performs arithmetic calculations and logic decisions ^ Central processing unit (CPU)^ ^ Supervises and coordinates the other sections of the computer ^ Secondary storage unit^ ^ Cheap, long-term, high-capacity storage, stores inactive programs

A Bit of History  Which was the first programmable computer?  Charles Babbage’s^ Analytical Engine

(early 1800’s)

^ First programmer? ^ Ada Augusta, Countess of Lovelace; Charles’s colleagueand daughter of Lord Byron

Evolution of Operating Systems^ ^ Batch processing^ ^ Do only one job or task at a time^ ^ Operating systems^ ^ Manage transitions between jobs^ ^ Increased throughput^ ^ Amount of work computers process^ ^ Multiprogramming^ ^ Many jobs or tasks sharing a computer’s resources^ ^ Timesharing^ ^ Perform a small portion of one user’s job then move on toservice the next user

Personal ComputingDistributed ComputingClient/Server Computing^ ^ Personal computers^ ^ Economical enough for individual^ ^ Distributed computing^ ^ Organizations computing is distributed over networks^ ^ Client/server computing^ ^ Sharing of information, across computer networks,between file servers and clients (personal computers)

Some High-Level Languages  Java used to ^ Create web pages with dynamic and interactive content ^ Develop large-scale enterprise applications ^ Enhance the functionality of web servers ^ Provide applications for consumer devices (such as cell phones, pagers andpersonal digital assistants)  FORTRAN ^ Used in scientific and engineering applications  COBOL ^ Used to manipulate large amounts of data  Pascal ^ Used to teach structured programming  C/C++ ^ Middle-level language ^ Provides facilities for both high level as well as low level programming

History of C and C++  C++ evolved from C ^ C evolved from two other programming languages, BCPL and B  ANSI C ^ Established worldwide standards for C programming  C invented by Dennis Ritchie of AT&T Bell Labs in the 1970s  C++ by Bjarne Stroustrup of the same labs in the early 1980s  C++ “spruces up” C ^ Provides capabilities for object-oriented programming^ ^ Objects are reusable software components that model things in the real world^ ^ Object-oriented programs are easy to understand, correct and modify  C is a subset of C++
