Computers and the Internet Type: Training https://www.khanacademy.org/computing/computers-and-internet Khan Academy is a non-profit organisation that produces multimedia lessons covering mathematics, science, economics, life skills, languages, and many other subjects. It also offers courses from partner sites. The lessons on Khan Academy are aimed at both students and adults. For students, the content is classified based on the US education system. Khan Academy was founded in the early 2000s by Sal Khan. He started tutoring his cousin in math. Eventually, Khan made the lessons available on YouTube. The Computers and the Internet module consists of five units, each broken down into short modules. Those who take the course earn master points.   Snap! Type: Programming https://snap.berkeley.edu/ Snap! is a graphical programming language for both children and adults. Snap! uses coloured jigsaw-like constructs to build a program.

AWS DirectConnect enables organisations to establish dedicated and private network connections between their data centre and AWS Availability Zones. This service provides a secure, reliable, and high-bandwidth connection, creating a direct, Point-To-Point (PTP) link between the organisation and AWS. Without DirectConnect, data would have to be transmitted over the public internet. This adds an added risk that organisations may want to avoid. Without AWS DirectConnect: The organisation would have had to expose its data centres via public IP addresses because connectivity to AWS would take place over the internet. On the public internet there may be nodes that operate the harvest-now, decrypt-in-the-future surveillance strategy that relies on the acquisition and long-term storage of currently unreadable encrypted data awaiting possible breakthroughs in decryption technology that would render it readable in the future. When using the public internet, the maximum possible perfo

Any organisation that uses software must deal with the topic of software obsolescence. Irrespective of whether end users interact directly with it or if it is embedded within a device, the day will come when the software is outdated and no longer supported. Software obsolescence happens because of technological, functional, regulatory, and security factors, or a combination of them. Organisations mature and evolve through mergers, acquisitions, organic growth, and changes in company direction. Each one of these adds systems that will someday become obsolete. Ignoring software obsolescence has consequences, namely: Security risks: Outdated software is more likely to have known security vulnerabilities that can be exploited by attackers. Compliance risks: Organisations that use outdated software may be in violation of government regulations. Performance issues: Outdated software may not run as efficiently as newer software and may not be compatible with newer hardware. Compatibilit

The journey In the 1950s and 1960s, computer systems came bundled with source code that had to be compiled. Because of the high acquisition and operation costs of computers, only universities and large companies could afford them. These same entities had the resources to find and fix bugs in the code and add functionality to meet their needs. Rather than keep these changes close to their chests, a sense of community emerged wherein the source code with code adjustments was shared with others. The idea lies in the sharing of knowledge. As the number of users and the contributions increased, it became necessary to catalogue and coordinate these contributions, and repositories were created. These repositories allowed users to search for code that added new functionality or corrected a bug. The community would iteratively take the code and compile it on their systems. If they improved the code, they would upload these improvements to the repositories, benefiting others. Placing code in t
