SEMANTIC ANALYSIS

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

They are the main concepts covered by drdobbs.com.

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

Topics
C/C++ Users Journal Confidence: 88% Arrow up

C/C++ Users Journal was a computer magazine published by CMP Media LLC in the United States.

The magazine concentrated on the C++ programming language and was one of the last printed magazines to cover the topic.

HTML5 Confidence: 88% Arrow up

HTML5 is a markup language used for structuring and presenting content on the World Wide Web.

It is the fifth and current version of the HTML standard.

Java (programming language) Confidence: 86% Arrow up

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.

Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.

The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

Byte Confidence: 79% Arrow up

The byte is a unit of digital information that most commonly consists of eight bits.

Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.

Software development Confidence: 77% Arrow up

Software development is the process of computer programming, documenting, testing, and bug fixing involved in creating and maintaining applications and frameworks resulting in a software product.

Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process.

Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.
