This is the first part of using the internet: beginners’ guide. This guide is devoted to teaching beginners, and junior secondary school students on how to use the internet. It is tailored along-side the curriculum provided for Junior Secondary school students in Nigeria. It begins with definition of basic terms, then delve into how to create emails, etc.
Internet: The Internet is a global system of interconnected computer networks of private, public, academic, business and government networks. It uses the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide.
World Wide Web (www): This is a highly organized system of retrieving documents through the internet. According to the World Wide Web Consortium, it can be defined as is an information system of interlinked hypertext documents that are accessed via the Internet. The documents accessed through the www are formatted in a markup language called HTML (HyperText Markup Language) which supports links to other documents. www has the capacity to deliver different documents ranging from texts, graphics, audio, to video. The hypertext documents make it easy for one to jump from one document to another simply by clicking on hypertext links.
Electronic Mail (E-mail): Email is a system of exchanging digital messages from one person (sender) to another (recipient) through the internet. Digital messages can be composed, processed, stored and managed using web-based emails such as Yahoo, Gmail, etc or specialized email applications such as Microsoft Outlook, Mozilla Thunderbird, etc.
Email address: Before a digital message can be sent, the sender and recipient need to own email accounts from where their addresses would be used to send and deliver the message respectively. An email address is, therefore, an email account or email box identifier to which digital messages are sent and received.
Website: A website can be defined as related web pages with information of the owner, hosted in a web domain. These pages are documents created using HTML (HyperText Markup Language) or XHTML (Extensible HyperText Markup Language) format and are delivered as text, audio, image or video to the public via the internet using www. Companies, institutions, government agencies, businesses, etc own websites which can be browsed on the internet using web browsers. To browse a website, one should be familiar with the website address otherwise called URL (Universal Resource Locator).
A web browser or simply browser is a software application used to browse the World Wide Web. Different web browsers have evolved since 1991, beginning with www (Nexus), however, the most popular browsers since 2010 include: Mozilla Firefox, Safari, Internet Explorer, Opera, and Google Chrome. These browsers can be downloaded from the internet free of charge.
When using the internet in any part of the world, a web browser is required. To identify these browsers in a computer system, look out for the following icons on the desktop:
An email address must have a prefix (usually the name of the owner or organization that owns the email) and a suffix (usually the name of the email processor e.g. Yahoo, Gmail, Hotmail, one box, etc). The prefix and suffix are linked together using @. All the components of an email are written together without spaces.
An email address can be identified with the following examples: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, etc.
A website address or Uniform Resource Locator (URL) is a reference to online resources. It is an address that finds or locates resources saved in a web page. It is usually written in this format: http://www.yahoo.com, however, one can omit the HTTP:// when entering the URL in the address bar. Some examples of websites are www.yahoomail.com, www.google.com, www.waecdirect.org, www.jamb.org.ng, http://www.jamb.org.ng/Unifiedtme4/, www.mouau.edu.ng, etc.
You can simply open free webmail using any of Yahoo mail, Gmail, or Hotmail. To create an email account, follow the following steps:
- Type the URL of the free webmail you want to use in the address bar of your favorite web browser, e.g. www.gmail.com, www.hotmail.com, etc. We are working with yahoo mail so we type www.yahoomail.com. Then, press Enter.
- Wait for some time, depending on your internet connection speed; the page shown below will open. (Note: The page may vary, depending on the advert on display. What’s important is the YAHOO! pane).
- In the above window, in the YAHOO! pane, click on Create Account or on Don’t have an account? Sign up. The page below will open.
- Fill in all the necessary information in the form above, starting with your first name, last name, username (the name you want for your email account, e.g. chidex2015; (do not add @yahoo.com)), password (a secret key which only you should know. This key must be eight characters including uppercase, lowercase, and number, e.g. Agam2016), mobile number (Click the drop-down arrow and choose Nigeria from the box, then enter your mobile number leaving the first 0), birthday and sex.
- Click Create account.
- In the next window that appears, confirm your phone number and click send. A code will be sent to your phone for confirmation. Confirm the code and you’re good to go.
- Click on Submit code. Your account has been created.
The following are the benefits of using the internet.
- Information Exchange: With the internet, it is faster and easier to communicate. Both formal and informal communication had been easier and faster through various internet communication applications such as email, Whatsup, 2go, Skype, Google Voice, Instant messaging, etc.
- E- learning : The internet has popularized the acquisition of education online. Hence, geographical location, time and distance is no longer a barrier to attaining heights in education. One can be in Nigeria and study at the University of Liverpool at the comfort of his home or office. Also, multinational companies and large organizations can train and organize conferences for their staff through online platforms.
- E-Business: Online buying and selling, banking and different marketing activities have been made popular through the internet. One can place an order for goods or perform a banking transaction from his/her home or office without going to the business location.
- E-Library: Education and research have taken a new dimension through the use of e-library, made possible by the internet. Anyone wishing to conduct any form of research or looking for information on any field of study can log on to an e-library service. This is relatively cheaper and easier to use. Users will always avoid physical confrontation and congestion.
- E-Entertainment: The entertainment industry has grown larger and access to entertainment media has also grown through the use of the internet. Through the internet, several entertainment industries have been able to market their products and increase their popularity. The internet has also made finding the latest updates about celebrities and exploring lifestyles become a day-to-day activity.
- Social Networking: Family and friends, colleagues and different people all over the world can stay connected, keep in touch and share ideas through the use of various social networking platforms made available through the internet.
In spite of the numerous benefits of using the internet, the internet has been abused by many. Some of the abuses include:
- Fraud and theft of personal information: The use of the internet limits our privacy and make our personal data vulnerable to theft. Most times we supply our personal information during online banking, social networking, etc; these private data may sometimes be intercepted by fraudsters and hackers. These fraudsters can access our sensitive information through unsecured connections by planting phishing software.
- Pornography: Pornography and age-inappropriate content are one of the major abuse of the Internet. There are thousands of pornographic sites on the Internet that can be detrimental to children and teenagers. Lack of control over the distribution and unrestricted access to pornographic material is damaging to teens and children, however, parents can lock these harmful sites as well as monitor the sites viewed by their children.
- Malware attacks: The internet usually leaves our computer open to malware attack. Virus, worm and Trojan horse can easily attack and harm our computers and important files through the internet. Virus programs are unobtrusive and may get activated by clicking a seemingly harmless link or email. In addition to attacking our files, malware attacks may end up crashing our system.
- Spamming: Spam emails are unwanted e-mails which serve no purpose to the receiver but serve a purpose to the sender. These emails clog our mailboxes and make it difficult for us to access our emails. Though email service providers have security systems that attempt to guard against spamming, most times, spam emails find their way into our mailbox.
The term “internet environment” in this section refers to the browsing window. That is, the environment an internet user interacts with when he/she is browsing the internet. Students should be acquainted with the icons, buttons, links, and menus on a web page which will enable them to use the internet without difficulties. A web page is a page that is displayed when a website address (URL), typed in a web browser’s address bar opens. We have different web browsers, as identified in the previous section, however, for illustration purposes, we shall use the internet explorer.
Internet Explorer is a browser that is shipped with the Microsoft Windows operating system. Thus, it is readily available in every system that has Windows operating system installed in it. When you open the internet explorer, a typical window, as shown below is displayed.
We shall concentrate on identifying some of the icons on this window.
When an internet user opens a web page or browser, he/she can easily understand the uses of the icons and buttons on the internet environment by simply pointing at each icon or button and reading the displayed information. For example, consider the following web page: http://www.waecdirect.org/
This is WAEC result checking webpage. It is very simple to use and self-explanatory. Simply enter your examination number, card serial number and pin in the spaces provided; then choose the year and type of exam and click submit. Your result is displayed (if all information is correctly entered). You can also click on the hyperlinks: click here to visit our corporate website, FAQ, Scratchcard Outlets, Alternative Channels to display each of the web pages. For example, clicking on click here to visit our corporate website displays the following web page:
The above webpage has the following menus with their submenus: Home, About us, WAEC Profile, Council Members, Examinations, FAQ, Result, Contact us and News. When you click on any of the menus or their submenu, the selected webpage will be displayed.
