By contrast, system software controls and coordinates computer operations. G eneral-purpose applications are software used by many people to accomplish frequently performed tasks. Application software designed for the general consumer is written to improve productivity and/or to present data in more meaningful ways. Examples of popular general-purpose applications: word processors, spreadsheets, databases, e-mail, Internet browsers, programs that produce a payroll report, etc. The four types of general-purpose applications are personal productivity programs, multimedia and graphics software, Internet programs, and home/educational software.

2 A. Personal Productivity Programs Personal productivity programs help individuals do their work more effectively and efficiently. Productivity programs such as word processors, spreadsheets, and databases are all horizontal applications. Their value to us is that they perform their functions regardless of the subject matter. Other productivity software are presentation graphics programs and personal information managers. B. Multimedia and Graphics Software The term multimedia refers to any application that involves two or more media, such as audio, graphics, or video. Multimedia and graphics software includes professional desktop publishing programs (such as QuarkXPress), image-editing programs (such as Photoshop), and three-dimensional rendering programs (such as computer-aided design [CAD] programs). To reduce the size of multimedia files, most software uses compression/decompression algorithms called codecs. Compression —reducing the file size of multimedia software; Lossless—file will be restored with no flaws; Lossy—eliminates information that is not perceived; Decompression —restoring the file to full size. Paint Programs Paint programs can save your files as: Graphics Interchange Format (GIF)—lossless, simple images, solid color; Joint Photographic Experts Group (JPEG)— lossy, photographs; Portable Network Graphics (PNG)—lossless; Windows Bitmap (BMP)— optional compression.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
