Free and open source software presentation
Transcript of Free and open source software presentation
Any questions? One of the main problems with free and open source software is that they are not straightforward to use or install. Possible training will need to be undertaken before a user can understand how to use certain software, which can mean additional costs are incurred. Another problem is that there is no comprehensive support or maintenance and this varies from one piece of software to another. There is also no guarantee of updates to the free and open source software, as this is reliant on developers contributing to new ideas, code and functionality. Various legal issues associated with free and open source software such as infringements of Intellectual Property rights and copyright issues. A brief history 1950's & 60's 1970's and 80's 1990 and 2000's 2000's and beyond Almost all software was produced by computer science academics and researchers working in collaboration. As such, it was generally distributed under the principles of openness and was not seen as a commodity in itself. In the early 1970s the first distributions of UNIX (operating system) were available at no cost to the government and academic researchers, but these versions did not come with permissions to redistribute or distribute modified versions.
Also a variety of computer vendors and software companies began charging for software licenses and imposing legal restrictions on new software through copy right, trademarks etc. The Linux kernel, started by Linus Torvalds, was released as freely modifiable source code in 1991. Linux remains free software and many businesses offer customized Linux-based products, or distributions, with commercial support.
In the mid to late 90s, when many website-based companies were starting up, free software became a popular choice, especially for web servers (Apache) 1970 2000 + 1950 1990 In 2005, Android was launched; which is the first Linux based operating system designed primarily for touchscreen mobile devices such as smartphones and tablets. Android has a large community of developers writing applications ("apps") that extend the functionality of the devices.
Android had a worldwide smartphone market share of 75% during the third quarter of 2012, with 500 million devices activated in total. ..Beyond Increase in familiarity of open source and free software and more use from both public and private sectors.
