Basics of the Internet
The Internet in its earlier decades was simple and easy to use. But as years go by, it becomes more complex and very fast. After using the Net for more than four years, I got inspired to review its basics because I seem to have forgotten it! Let's get back to Internet basics and basic components.
The most predominant component of the Internet model is the Internet Protocol (IP) which provides addressing systems (IP addresses) for computers on the Internet. It enables internetworking and essentially establishes the Internet itself. But one of the cause of Internet connection problems is the exhaustion of IPv4 (IP version 4) because of the explosive growth of the Internet. Now we would not be in the basics anymore if we continue so …
How the InterNet Works for Us
1. Browser -we surf or search for the site we want
2. Your ISP -the Net connects to your ISP and IP address then to the following:
3. NAP (Network Access Protection) Server
5. ISP of Searched URL
6. You're now connected to your searched URL or site
Connecting to the Internet
Broadband – Most users prefer this connection because it's the fastest and most stable. But you can only use this on a fixed location.
WiFi or Wireless – As opposed to broadband, you can use this connection where ever you are, ergo wireless.
Programs and Applications
Before you can do something with your computer, you must have programs and applications. When you buy a new computer, there are already installed programs that would let you add more.
Browsers are the doors to the Net. Our connection to the Internet is useless without them. In order for us to browse or 'surf' the Internet and connect to other websites, we need to use browsers. Examples of Browsers:
The main reason for connecting to the Net is networking which is sharing of resources and information among computers and devices connected to the network. By networking, users can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephony, video telephone calls, and videoconferencing.
Social Networking is mainly done for leisure. By using programs and applications, people can join a social network and exchange messages and pictures. The most popular social network sites are Facebook and Twitter. Serious working people see social networks as time wasters.
Internet Safety and Security
Many new computer users do not realize that maintaining their gadgets is not a simple task and fails to maintain the safety and security of their computers, either unintentionally or by recklessness, until one day, their computer 'crashes' and find out that their gadget would not work anymore.
Tasks for maintenance and safety:
Updating Operating System
Updating Antivirus, Antimalware, Antispyware
Using link scanners that check if the site we plan to visit is safe
Deleting suspicious 'flash cookies'
Doing all these tasks regularly
Shutting off and unplugging your PC
Most expert technologists advise shutting off and unplugging your PC if it would be left unattended for hours. I agree with that. If you leave your PC in sleep or hybernate mode, malicious programs may be able to operate in the background and your PC's battery life would be shorter.
(And I'm not sure yet if these tasks are complete!)
We can update any of these automatically but sometimes for some reason, it stops working. So another task is checking for updates.
Things that could happen if we ignore safety:
Malfunction of your computer
Malware, spyware, or virus infection which could stop or ruin our computers
Identity theft which could lead to stolen bank accounts -This is the most dangerous and most popular among computer criminals
Hijacking of your personal weblogs, email account, or sites
I hope I have convinced us all that Internet security is a must. Some techies believe that we have to be paranoid about our internet safety to be really safe.
