Virtual Memory
In computing, virtual memory is a memory management technique developed for multitasking kernels. This technique virtualizes a computer architecture's various forms of computer data storage, allowing a program to be designed as though there is only one kind of memory, "virtual" memory, which behaves like directly addressable read/write memory (RAM). TERM 17
OS- Monitor Security
DEFINITION 17 -software based firewalls software that lies between your computer and a network -access control security features that control who can access resources through operating system TERM 18
OS-user interace creation
DEFINITION 18 -each OS has different look, different--Biggest progelm in cross-platform development TERM 19
Why Does an OS Matter?
DEFINITION 19 They provide different features-memory management, GUI,security, communicationsApplication software is written foran OS-Choose applications, then choose OSOS were once proprietary-For ex., Sun's OS worked only on Sun- manufacted CPUs-Choice of OS dictates choice of hardware, but choices are broader now TERM 20
Writing Software
DEFINITION 20 Programming languages are artificial languages used to control behavior of computer provide standards, syntax, statements and instructions for writing computer software many diff. programming languages created and new languages every year professional programmers use integrated development environment (IDE) to write code
IDE
A software application that includes an editor (sort of progammer's word processor) debugger, and compiler, among other tools TERM 22

Object Code
DEFINITION 24 program in a form that computer can execute--11-sometimes called "machine code" or "binary" TERM 25
Source Code + object code
DEFINITION 25 Compilers and interpreters are types of software that translate source code into object code
