A terminal emulator is computer software which emulates a dumb video terminal within some other display architecture.

Video editing is the process of editing motion video footage. In the new age of personal video, video editing is becoming a central function of the desktop, with the popularity of video editing software ever increasing.

A plotting tool is computer software which helps to analyze and visualize data, often of a scientific nature. Using this type of software, users can generate plots of functions, data and data fits. Software of this nature typically includes additional functionality, such as data analysis functions including curve fitting.

MySQL is a relational database management system. It provides a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL is the most popular open source database, and is the database component of the LAMP software stack. LAMP consists of the Apache web server, MySQL and PHP, the essential building blocks to run a general purpose web server. MySQL is used and championed by many large organizations including Google, Facebook, BBC, Intel, Sun, SAP, Dell, AMD, Novell, Veritas and many others.

Developers who want to accelerate game development benefit enormously from tools known as game engines. This type of software application helps games to be coded efficiently and easily without compromising on its quality. Game engines employ state-of-the-art technology to ensure that developers can concentrate on generating new scenery, models, and sounds, or to put an alternative spin on existing game material.

Game engines offer huge benefits to game developers. The main functionality they provide is the library of core functions used in a computer game. This often includes a realtime rendering engine for 2D or 3D graphics, physics engine with collision detection, a character animation system, scene graph, sound, artificial intelligence, threading, networking, input, streaming localization support, debugging tools, integration with languages, and the provision of performance monitoring and optimization tools.

For many individuals, computer gaming is nowadays an essential part of everyday life. This should not be seen as a negative. Whilst violent computer games have sometimes been identified as contributory factors in criminal activity, and undeniably they can be very addictive, it is important to recognise the real benefits that games offer besides simply providing a means of great entertainment.

A proverb that often springs to mind during the day is that all work and no play makes Jack a dull boy. Breaking up the monotony of the daily grind (also known as work) cannot be underestimated. Computer games are a great form of entertainment, less passive that watching the TV, just as challenging as completing the Times crossword, but much more fun.

If Linux is going to make significant strides in increasing market desktop share, it needs to be able to compete with Windows in all areas. The average computer user typically just wants a single operating system to use for their work, to surf the net, to keep in contact with family and friends, and to have some fun. Having to reboot between operating systems is frankly too inconvenient for many users, as well as being perceived as too difficult. Whilst you can run many Windows software from Linux (e.g. by using virtualisation software, or Wine), again this simply appears to add to the complexity of using the PC. Furthermore, whilst Wine does allow some of the hottest Windows games to run under Linux, it is inevitable there will always be some incompatibility issues.

Surveys suggest that up to 90% of home computer users do not back up their data. That is a pretty frightening statistic bearing in mind how valuable and precious users' files are. Computer users who do not backup their files are at risk of losing all of their personal and irreplaceable documents. The hard drive in a PC can malfunction at any time, sometimes without any warning at all. Alternatively, the computer's hard disk can be damaged by an accident, a fire, flood, power cut, or infected by a virus.

There is no denying the huge selection of open source games available for Linux. Playing through all of these games would entertain many gamers for years. Nevertheless, there is still a massive market for commercial games. If Linux is ever going to usurp the desktop market, it needs a regular source of native high quality games that rival commercial games available on Windows.

Why spend your hard earned money on proprietary software when open source software provides a similar (or better) amount of functionality? That's a very good question.

The amount of software that is available for Linux is truly mind-boggling with tens of thousands of applications available to download, including an impressive arsenal of open source games. However, it is fair to say that the amount of commercial games released for Linux continues to be in short supply in comparison with the number of titles released under Windows.

Many computer users have an insatiable appetite to deepen their understanding of computer operating systems and computer software. Linux users are no different in that respect. At the same time as developing a huge range of open source software, the Linux community fortunately has also written a vast range of documentation in the form of books, guides, tutorials, HOWTOs, man pages, and other help to aid the learning process. Some of this documentation is intended specifically for a newcomer to Linux, or those that are seeking to move away from a proprietary world and embrace freedom.

Astrology is a set of traditions, beliefs and systems which hold that there is a connection between the movement of heavenly bodies and events that take place on Earth such as human affairs, and personality. Astrologists use the position of the planets to try to predict future events, and to inform the psychological understanding of an individual's psyche.

High dynamic range imaging (HDR) is an important technology for photographers. It is a collection of techniques that allow a wider dynamic range of luminances between the lightest and darkest areas of an image.

File Transfer Protocol (FTP) is a popular and time-honored method of transferring files to and from a remote network site. FTP is built on a client-server architecture and uses separate control and data connections between the client and server applications. The FTP client connects to the FTP server, and enables the user to send and retrieves files from that server.

Medical Practice Management Software (MPMS) is a type of software that is designed to supervise and support the day-to-day operations of a medical practice. This category of software typically offers functionality such as data entry, scheduling appointments, billing, reporting, records management, the generation of reports, accounting, and capturing patient demographics.

Medical imaging is an essential, non-invasive, routine activity performed by radiographers and radiologic technologists. It is a discipline of the health profession which involves using technology to capture images of the human body.

In developed countries, healthcare workers represent a significant proportion of the working population. For example, in the United Kingdom, more than 1 million people work for the National Health Service, a publicly funded healthcare system. Medical software therefore has a huge market to tap. Whatever stage of a country's economic development, health care is one of the most important elements in society.
