Microsoft is one of the most influential technology companies in the world. It produces some of the most popular computer software, cloud computing services, video games, and hardware platforms for tablets, smartphones, and computers. The company is headquartered in Redmond, Washington, and has offices around the globe. Some of Microsoft’s most notable products include the Windows operating system, the Microsoft Office suite of productivity software and services, Bing search, the Edge web browser, and the Visual Studio IDE. It also publishes books through its Microsoft Press imprint and makes Xbox video game consoles, Surface tablet computers, and augmented reality (AR) hardware through the HoloLens brand. While the company doesn’t get the same amount of attention as tech giants like Google and Apple, it is still a powerful force to be reckoned with. It runs the world’s most popular cloud computing service, Azure, and maintains Windows 11 and the entire Office suite of software applications. It’s also building new hardware like the Surface Series X and making a big splash in the gaming industry with its Xbox lineup of consoles and various gaming subscription services. The company is the largest software vendor in the world, and its best-known product is the Windows operating system. Its other major software products are the Office suite of productivity apps, the Edge browser, and the Azure cloud platform. The company also publishes books through its Microsoft Press and makes video games through the Xbox Game Studios division. The company is a member of the Fortune 500 list of the largest United States corporations by revenue and is considered to be among the Big Five computer software companies, alongside Alphabet (parent company of Google), Amazon, Apple, and Facebook. Founded in 1975 by Bill Gates and Paul Allen, two Harvard University classmates, the company started out developing a compiler for BASIC, a popular mainframe computer programming language that was used on an early personal computer called the Altair 8800. After securing a contract with the Altair’s manufacturer, Micro Instrumentation and Telemetry Systems, to develop a BASIC interpreter for it, the pair founded their company and named it after its primary product lines — microcomputer and software. Since then, Microsoft has expanded to become one of the biggest technology companies in the world. Its flagship software products now include Word, Excel, Outlook, PowerPoint, Skype, and SharePoint. Its cloud offerings include Azure and OneDrive, while its mobile devices feature the Microsoft Edge and Bing browsers. Its video game lineup includes the Xbox series of consoles and the Surface Pro line of touchscreen laptops and tablets. The company has also established a reputation as an expert in the field of artificial intelligence, and its president has spoken out about the responsible use of the technology. It has also made significant investments in companies like OpenAI and GitHub, the source code repository. In addition to its own hardware and software, the company has partnerships with a number of other tech companies including Intel and AMD.

Google, the world’s most popular search engine, handles billions of searches each day. It is so dominant that it has entered the lexicon as a verb: to google is to search the Internet. Google’s stated mission is to “organize the world’s information and make it universally accessible and useful.” The company was founded by Larry Page and Sergey Brin in 1998 while they were Ph.D. students at Stanford University. They worked out of their college dorms to build a search engine they called Backrub, then later renamed it Google after a misspelling of the mathematical term googol (a number one followed by 100 zeroes). Early in its development, the company focused on developing software to index and organize Web pages. Using this, they could create the most relevant search results for users. In addition to the search engine, the company has expanded to offer more services such as email (Gmail), online document creation, maps and location-based services, video sharing, and hardware products. Google also provides a range of advertising technologies such as Google AdWords and Google Analytics. The core of Google’s technology is a system called PageRank, which ranks websites based on how often their content appears in searches and the relative importance of those keywords. This is determined by an algorithm that counts how many times the word or phrase appears in a web page, as well as how other web pages link to the target site. The result is a page ranking that can be adjusted in real-time, giving the search engine the ability to provide results that are both current and accurate. To handle the enormous volumes of data that Google collects, it has built 11 data centers around the world. These facilities house tens of thousands of computers, each of which is interlinked to the others. The heart of Google’s data collection infrastructure is three proprietary pieces of computer code: GFS, Bigtable and MapReduce. GFS stores the data in chunks across multiple machines; Bigtable is the database program that assembles higher-level data from the chunks; and MapReduce processes the data into final forms that can be displayed or used by other applications. Throughout its history, Google has launched and discontinued a multitude of different services. Some of these were short-lived experiments, while others were more long-term projects. Some of the more notable discontinued Google services include:

A thorough understanding of linux is crucial to your IT career, because this operating system powers everything from smartphones and tablets to supercomputers and gaming consoles. Its lightweight nature, modularity, and security features make it an ideal choice for devices that require a low-power, low-maintenance environment. The operating system’s open-source design, meanwhile, promotes collaboration and innovation. Its code is freely available to anyone who wants to use it, and contributions from thousands of individuals have resulted in a powerful, versatile system with nearly unlimited applications. Unlike proprietary systems like Microsoft Windows, which are based on license fees, linux is free to use. In addition, it’s easy to install and works on a wide range of hardware platforms, including computers, laptops, and mobile devices. Its stability and reliability are also key factors that make it an excellent platform for servers, where uptime is critical. It’s not uncommon for Linux servers to run for years without needing to be restarted, and it can handle a large number of simultaneous connections without losing performance. Because Linux is open source, users can customize their installations to best suit their needs. There are over 200 different versions of the operating system, and they’re referred to as distributions (or distros for short). DistroWatch maintains a master list of these variants, and each has its own take on desktop environments, package management systems, and philosophies. Some are geared toward newbies, others to hardcore developers, and still others are optimized for specific types of hardware. For example, many Linux distributions provide what is called a “Live” version, which allows you to try out the software on your computer or mobile device without changing the existing operating system. That way, you can get a feel for the system before you commit to it. You can even purchase a fully assembled PC with Linux pre-installed from manufacturers such as CurrentBuild Computer, which offers the Sense mini PC, Sense mini PC 2, Dream PC and Speed WS models. Once you’ve mastered the basics, it’s time to start exploring what makes linux so unique. In particular, learning to use the terminal is essential. This is a powerful tool that can be used to perform countless tasks, from navigating files and directories to performing advanced text manipulation and navigation with tools such as vim or emacs. The next step is to familiarize yourself with the huge selection of software that’s available for linux, whether it’s natively written for the OS or ported over from other platforms. From office suites to graphic design software, you’ll find something for every need, and the breadth of the collection is a testament to the versatility of the operating system.

The Internet is a network of networks that connects computers and devices worldwide. It is used for a wide range of activities, including sending and receiving information, entertainment, education, and business. The Internet is free and accessible to anyone with a device that can connect to it. It is governed by a set of protocols that dictate how data is sent and received over the network. The internet is a massive reservoir of information that makes it possible for people to learn nearly anything they want to in a short amount of time. This includes everything from academic research to cooking recipes, and all of it can be easily accessed on a computer or mobile device with a high-speed connection. This is in stark contrast to 50 years ago, when it would have been nearly impossible to find and obtain this much knowledge. In addition to offering a wealth of knowledge, the Internet also provides people with a platform to express themselves, showcase their talents and engage in discussions with others. Many online activities are free to use, while others require a subscription or payment to access certain content. People can listen to music, watch movies and TV shows, play games, participate in chat rooms, and communicate with friends and family via the Internet. In some cases, this communication can be done through a voice or video call. People can also shop for products and services through the Internet, and it is common to pay bills or check bank balances online. One of the most significant uses of the Internet is in healthcare. For example, telemedicine can help people with chronic conditions or who are disabled stay in their homes while being treated by doctors remotely. This technology is especially helpful for people with limited transportation options or who are unable to leave their homes due to health issues. The Internet is also useful for registering to vote and finding employment. It allows individuals to access jobs and apply for positions in a matter of seconds, while also helping them to keep up with the latest job trends. The Internet can also be a powerful tool for promoting awareness about health issues and social injustices. The internet also helps businesses to improve their productivity and team’s efficiency. It allows them to access tools that facilitate collaboration and allow employees to work from home or on the go. It also enables companies to market their products and services to a global audience. However, there are some negative impacts of the Internet that people should be aware of. For instance, it can be addictive and distracting for some people, especially teenagers. This can lead to them not being able to focus on their work or have a healthy social life outside of the Internet. It can also cause them to value their virtual life more than their real one, and they may become aggressive or depressed if they lose access to it.

Websites are collections of web pages that can be accessed by people anywhere in the world via the Internet. They can be used to share information, entertainment or services and are generally managed by a person or organization. The opening page of a website is usually called the home page. Websites are hosted on computers connected to the Internet, known as servers. Servers can format and send web pages to users worldwide as requested 24 hours a day, 7 days a week. Web pages are digital files written using HTML, a computer language that allows developers to plan out the contents of each web page. The code is then executed by the server to display the page. Web pages are also indexed and searched by search engines to provide people with information they are seeking online. When deciding what type of website to build, consider the goals and needs of your business or organisation. For example, do you want to promote a service, sell products or generate leads? This will influence the type of content you need on your site and how it is structured. If you want to attract customers, make sure that your website is visible on search engines, such as Google. This involves using keywords and optimising your website for speed. The most popular types of websites include blogs, e-commerce stores and static brochure sites. A blog is a regularly updated website that can be used for personal or professional purposes. It may contain a combination of text and visual elements, but it is important to keep in mind that the visual aspect is often less relevant than the information it contains. An e-commerce store is a website that allows people to buy products or services online. This is typically a good option for businesses that sell physical products or digital downloads, as it provides an easy way for customers to purchase and receive their goods. An e-commerce store should be easy to navigate and have clear call-to-actions. This will encourage customers to take the desired action, such as signing up for a newsletter or making a purchase. A brochure site is a simple website that comprises of few pages and can be used to share basic information about an organisation. They are typically viewed on desktop computers but can also be accessed on smartphones and tablets. Websites need to be updated and maintained to stay current and relevant. This includes adding new pages, fixing technical issues and keeping up with SEO techniques to improve search engine rankings. It is also a good idea to review your website on a regular basis and ask for feedback from visitors. This can help identify any issues that need to be addressed and allow you to improve your website to better meet the needs of your audience.
