In "Connecting to the Net" we learned about the different types of internet connections, bluetooth and wi-fi, various web browers and how to manage web browser settings. The different types of internet connections are: cable, DSL, FIOS, and some people still use their telephone line to get on-line. After you are on-line, there are many different browsers to choose from. For example you can download, Firefox, Internet Explorer (I.E), Safari, etc. Your web browser allows you to navigate through the internet, view web pages in HTML format, listen to audio and watch videos, E-mail and FTP, and downloading and uploading files.
In the "Internet and Web Security" lesson, I learned how to define a web threat, protect myself against web threats (cookies, malicious software, computer infestations, spyware, and internet phishing), and how to protect myself when it comes to online shopping. Your browser should always have the highest level of security set because spyware can hide inside programs and steal all your information, which allows hackers to steal your information and use it at their will. You should always have up to date virus software, firewall, and spyware software to help protect you against viruses, Trojan horses, spam, spyware, and hackers.
In the lesson "Internet Transmission", I learned TCP/IP Protocol, how to dissect a url, and list a Domain name and IP address. TCP or Transmission Control Protocol is responsible for breaking up and resembling data into packets and rerouting them to their destination. The IP address is a 32-bit addresses consisting of 4 numbers seperated by periods, used to uniquely identify a device on a network; the last numbers identifies the hosts.
My overall participation in the discussion, was lacking. I am having a hard time remembering what discussion is due when. I did do a little better this module, and I hope to improve greatly on the next module.
- Inter-Domain Routing (CIDR): allows the network administrators to expand the number of network nodes assigned to an IP address.
- Shared Registration System(SRS): is the registration system that allows private companies to handle registration of domain names.
- Location-based services (LBS): are wireless services offered to customers based on their physical location.
- Biometrics: involves using devices to measure biological data to identify a user.
