Open Source projects have lots of benefits to them. This is often because of the wide range of additional talent which can contribute to the project to improve it compared to only allowing a specific team to contribute.

The transparency of the source code also gives users a higher sense of trust in the software as anybody can vet the code themselves to find bugs or security flaws and report them. And with so many more professionals looking at the source it is likely that they could be found a lot sooner.

"open source code now powers about 90% of the internet"

Open source licenses are licenses that allow free redistribution of software, access to source code and enable developers to derive their own work from an author's work.

There are numerous OSS licenses, some popular ones include:
- Apache License 2.0

- Mozilla Public License 2.0
- Common Development and Distribution License

There are two types of categories for licenses, copyleft and permissive. Copyleft licenses is a licence in which code derived from the original open source code inherits its license terms. Permissive licenses is a license which provides more freedom for reuse modification and distribution.
