SEMANTIC ANALYSIS

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by leanlibrary.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Library (computing) Confidence: 74% Arrow up

In computer science, a library is a collection of non-volatile resources used by computer programs, often to develop software.

These may include configuration data, documentation, help data, message templates, pre-written code and subroutines, classes, values or type specifications.

In IBM's OS/360 and its successors they are referred to as partitioned data sets.

Plug-in (computing) Confidence: 73% Arrow up

In computing, a plug-in (or plugin, add-in, addin, add-on, addon, or extension) is a software component that adds a specific feature to an existing computer program.

When a program supports plug-ins, it enables customization.

The common examples are the plug-ins used in web browsers to add new features such as search-engines, virus scanners, or the ability to use a new file type such as a new video format.

Well-known browser plug-ins include the Adobe Flash Player, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution on a local Java virtual machine.

Information hiding Confidence: 70% Arrow up

In computer science, information hiding is the principle of segregation, of the design decisions in a computer program that are most likely to change, thus protecting other parts of the program from extensive modification if the design decision is changed.

The protection involves providing a stable interface which protects the remainder of the program from the implementation (the details that are most likely to change).

System resource Confidence: 69% Arrow up

In computing, a system resource, or simply resource, is any physical or virtual component of limited availability within a computer system.

Every device connected to a computer system is a resource.

Every internal system component is a resource.

Virtual system resources include files (concretely file handles), network connections (concretely network sockets), and memory areas.

Managing resources is referred to as resource management, and includes both preventing resource leaks (releasing a resource when a process has finished using it) and dealing with resource contention (when multiple processes wish to access a limited resource).

Software project management Confidence: 65% Arrow
