Linux is a Unix-like operating system. Just like Windows, Mac OS, and IOS, Linux is an operating system used by millions across the globe. Android itself is powered by the Linux operating system. Linux manages all the hardware resources that are associated with your computer. The software is famous because of the protection it grants from viruses, malware, and crashes. The Linux operating system is entirely free and is an open-source software meaning it can be altered by those equipped with the knowledge to code.

Java is a widely-known programming language that was invented in 1995 and is owned by Oracle. It is a server-side language that was created to let app developers "write once, run anywhere". It is easy and simple to learn and use and is powerful, fast, and secure. This object-oriented programming language lets the code be reused that automatically lowers the development cost. Java is specially used for android apps, web and application servers, games, database connections, etc. This programming language is closely related to C++ making it easier for the users to switch between the two.

Technical support or tech support are the services provided by any hardware or software company to users. They help in solving the technical difficulties the customers face with their products or services. Moreover, the tech support employees maintain, manage, and repair the IT faults. They are also responsible for resolving the network problems, installing and configuring hardware and software.

Software development is the mechanism by which programmers create computer programs. The Software Development Life Cycle (SDLC) is a framework for developing applications that follow technological needs and consumer requirements. It consists of many stages. The SDLC establishes an international standard that software developers can use to enhance and create their programs. It provides a well-defined framework for software developers to pursue in the production, maintenance, and design of premium quality software. The aim of the software development process is to create high-quality software on time and within budget.

Definition of Done (DoD) is a set of deliverables that are needed to devise software. These deliverables are valuable to the system and can be exemplified by writing code, coding comments, unit testing, integration testing, design documents, release notes, and so on.

Domain Name Systems, or DNS for short, is the internet's system for converting readable language, i.e., google.com, to machine language, i.e, 192.168. For a simple analogy, some call it the phonebook of the internet. Any website has its own IP address, for example, 192.168.160. Understandably this is hard to remember. So what a DNS does is link the domain name, google.com, with its IP address, 192.168.160.

A Virtual Private Network, VPN encrypts a device's internet access, activity, and identity through a secure server, making data theft and third-party traceability more difficult, and increasing the privacy and security of public and private networks, the internet, and Wi-Fi hotspots. The VPN is designed to protect one's system and network from being compromised.
