WEB DESIGN Web programming language Hyper Text Markup Language—HTML is a system used to convert a plain-text document into one optimized for viewing as a web page, integrating colors, graphics, fonts, and links.

SOFTWARE TRENDS Although the creation or acquisition of software is usually intended to solve or help address problems, licensing, owning, using, and maintaining software brings with it other problems that need to be addressed too. Software has a life cycle and often becomes outdated after a period of time. Microsoft Windows is an example of software having a life cycle. Once Microsoft offers a newer version of Windows, they only offer support for the previous version for a limited period of time. software licenses is a concern for modern organizations because licenses usually have expiration dates or limited downloads and the free software is more limited in capability. A software defect is known as a bug.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
