Introduction to Computer Science Flashcards
This is where programs and data are kept on a long-term basis. Common storage devices are the hard disk and optical disks.
Secondary Memory
Consists of several byres in memory that tell the processor to perform one machine operation.
Machine Instruction
Enables users to interact with application programs and operating system by using windows, buttons, menus, icons, mouse, and keyboard.
User Interface
Each tiny electronic operation that a processor core can perform
Machine Operation
Programs used by people to get their work done.
Application Programs
This is where programs and data are kept when the processor is actively using them. Sometimes called “RAM” or Random Access Memory. Random means that memory cells can be accessed in any order
Main Memory
- Noting permanent is kept in main memory.
- Smaller, but faster than secondary memory.
Consists of instructions for the processor
Programs
* There are two categories of programs: Application and Systems
What are some examples of systems programs?
Operating & network systems, programming language software, web site server, data backup
Coordinates the operation of the other hardware & software components. Always present when a computer is running. Manages the main storage and disks. Responsible for: starting application programs, starting them, & managing the resources that they need.
Operating System
Programs that keep the hardware and software running together smoothly.
Software Programs
Can be any information that a program needs
Data
Computer SOFTWARE consists of what two types of items?
Programs and data
A collection of machine instructions in main memory
Machine Language Program or executable program
A superset of the JRE. It includes development tools like: Java compiler, Javadoc, & debugger
Java Development Kit or (JDK)
What are some examples of application programs?
Word processors, spreadsheets, data base systems, graphics programs, web browsers
