● Computer six logical units: input unit, output unit, memory unit, arithmetic and logical unit, central processing unit, auxiliary storage unit ● Fortran is used for mathematical applications ● Cobol is mainly commercially available for accurate and efficient business applications ● The ADA programming language is funded by the US Department of Defense, which is based on Pascal. ● C system library consists of several parts: program development environment, language and C standard library ● C program usually takes six phases, ie edited, Pretreatment, compile, connection, loading, and execution ● C is the case sensitive. ● Object-oriented programming (OOP) uses software object to simulate the actual object. ● Objects have information hidden properties, ie, although objects can communicate with each other by defining interfaces, but objects typically do not know other objects, because the details are hidden in the object. ● Information hide is very important to good software projects.
