The Internet and the World Wide Web

I’m sure you’ve heard the phrase The Internet, but you may not know much about it or how it relates to your life. The Internet refers to a large collection of computers and other devices connected to each other through wires and wireless connections. These devices are linked together by standards like TCP/IP (Transmission Control Protocol/Internet Protocol), which define how information gets sent from one device to another, and they use services like Domain Name System (DNS) to direct users to the right location on the network.

How did it all start?
The precursor to today’s internet—the ARPANET—was designed as a distributed communications network. It was funded by grants from various government agencies, including NASA and DARPA (the U.S. Defense Department’s research agency). The idea behind ARPANET was to give military personnel access to all sorts of data—in any field they needed it in, regardless of where they were located at any given time. That’s why ARPANET was able to use a number of different protocols: It could send data through telephone lines, radio links, microwave networks, satellites… wherever an available connection could be found. This made ARPANET incredibly flexible—and also incredibly slow. In fact, sending a single message over ARPANET would take anywhere from 20 minutes to several hours. But that didn’t matter much, because few people used it anyway; in its first four years of operation, only about 40 nodes joined up with ARPANET. As you can imagine, sending messages back and forth between 40 computers is hardly useful for doing anything useful or interesting… so what good is an internet if there’s no one using it? That’s where computers come into play! Even though there weren’t many people using ARPANET yet, computer scientists had been working on something called packet switching for quite some time before then.

The importance of internet
The internet is a vast, global system of computer networks that can be accessed through any number of devices such as computers, mobile phones or tablets. It is made up of over 200 smaller systems such as web sites, mail servers and news services linked together by over 100 million km (62 million miles) of optical fibre cables running through earth orbit satellites. Almost 3 billion people use it every day. Every day more than 20 exabytes (20 billion gigabytes) of information are transferred through its various systems – enough to fill roughly 1m DVDs! The internet has changed forever how we work, socialize and shop. It has revolutionized business and politics, education and entertainment. Without it our lives would be very different indeed. We could not carry out many tasks without it; yet at times we take it for granted. In some countries most people have never used a telephone or even seen one before they start using the internet; however they soon become familiar with emailing friends, accessing government services online and using their mobiles to pay bills in shops etc… All of these changes have happened in just over 20 years since Al Gore invented his ‘information superhighway’.

This photograph shows three men using laptops at an outdoor café somewhere in France. Two of them are wearing earphones and so cannot hear each other speak, which means they might actually be working separately on different projects rather than discussing ideas directly. One man uses his laptop while holding it close to his chest rather than placing it on a table so he may well feel self-conscious about what he is doing.

The Future of Internet Marketing
While many traditional forms of marketing are struggling, internet marketing is a gold mine right now. It’s estimated that digital advertising will overtake TV ad spending by 2019. Of course, it helps if you know how to navigate your way through internet marketing in 2017. With all of these new changes it can be difficult to figure out what works best for your business and how to utilize them effectively. So here are a few tips on internet marketing that you can use in 2017: * Website * Build an awesome website with content relevant to your audience (that means NO widgets!) Make sure your site has SEO capabilities so that Google can find it when people look for keywords related to your products or services. The more traffic your site gets, the more money you make! * Email Marketing * Email marketing is still one of the most effective ways to get your name out there. And while some businesses have ditched email newsletters altogether, they’re missing out on potential customers who want to hear from them regularly. If you do decide to include an email newsletter as part of your digital marketing strategy, make sure it’s professional and easy for subscribers to unsubscribe from if they no longer want to receive emails from you. Don’t spam! * Social Media Marketing * You don’t need a degree in social media management—just stay consistent! Posting at least once per day on Facebook, Twitter, Instagram and LinkedIn should give you enough exposure that people start taking notice of what you’re doing online.

The growth of internet
The internet is a worldwide system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic technologies. The Internet carries an extensive range of information resources and services, such as email, websites, online videos and recreational content. When used with a web browser (or via specialized client software), it is possible to access almost all information on Earth. Applications have been created that allow users to doodle virtual landscapes or build detailed three-dimensional models that can be viewed from any angle. Search engines provide rapid access to information on virtually every subject. Online communication tools include instant messaging, audio and video conferencing, social networking, forums for discussions in various areas of interest, web feeds, blogs and microblogs. Many applications support open standards for exchanging data using XML files or JSON messages over HTTP connections; others support proprietary formats closed by patent protection mechanisms.[1] While most modern browsers support common standards,[2] they also enable extensions that can radically change how a user interacts with a website.
