Quickly master Internet components and boost your potential for in-demand Internet expertise by learning from this introductory minicore in Lesson-ON Demand format. This introductory minicourse is a part of a comprehensive series on CompTIA certification. In this lesson you will learn the basic Internet elements, including IP addressing, ICMP, protocol, and domain names. You will also study a variety of common Web applications and protocols, as well as gain a thorough understanding of multimedia content management and file sharing technologies. You will also study the security threats to the Internet and learn about how to protect yourself and your computer from Internet threats.

The fourth lesson in the series teaches you about the clever internet suite of products and services that Microsoft has created. With this software, you can access the Microsoft Office Suite at a faster and more efficient rate than ever before. You can develop Word, Excel, Power Point and PowerPoint documents that are ready to print. If you have been using Word for years, you can take advantage of the new improved version to help you create and edit more effectively. Microsoft Word for Mac can also be used as a powerful web browser using the Internet Explorer browser.

The fifth lesson explores the four different internet components that make up the so-called NNSA backbone. The NNSA backbone consists of fifteen different high-level language domains, which are specified in the US-idium system. These include such familiar areas as IMCP, ICMP, TCP, POP/SMTP, and IP packets. The internet components NSPOT, NIOS, and BIND are responsible for the backbone of most email systems and NNTP is responsible for the time server.

A final lesson in the series explores the use of network byte order and NSPOT in the network layer of Microsoft Windows. Network byte order, or DNS, refers to the set of tables found at the very root of every Windows-based service. This set of tables contains every IP address and domain names that have been assigned to computers on the network. A word to the wise, however, is that while the DNS system is very important for your email servers, it is not nearly as essential as NSPOT for Microsoft Windows.

As an example, consider that many business emails are sent by network clients with no idea of the domain name or IP address of the recipient. When they receive these emails, the reply usually includes a link to the server containing the relevant DNS entries. However, if the internet component NSPOT were included, the replies would contain dotted decimal instead of dashes.

To prevent this situation, it is necessary to include an NSPOT field with each SMTP message. The NSPOT field consists of one or more dashes (period) plus the internet component DNS address. This IP address is then sent as a query to the DNS server. If the server cannot locate the relevant entry within the database, it will return a failure error. For a normal Outlook client, this translates to an “SMTP failure” while for a webmail server it translates to a “NEGLECT” response. The “NEGLECT” message should be seen as the last resort for a user who has attempted to connect to a non-responsive internet component.

If you are sending an email from your work computer, it may have been sent by a networked user who has been directed from their ISP. Some ISPs do provide their customers with the capability to create wildcard internet components. With these internet components, a user with an ISP can connect to internet resources anywhere in the world that they have an internet connection. This capability makes it easy for someone to connect to your network via a Wi-Fi hotspot or a public Wi-Fi network without having to configure their firewall to allow access to your network. If you want to protect your network from unauthorized access, you should consider using a wildcard internet component instead of a traditional internet application. You can still set up restrictions on some of your networked users, but with a wildcard component, any user can access your network and not be restricted based on their location.

Although there are some inherent differences between internet applications and internet components, many of the tasks a web browser does can also be performed by internet components. For instance, you can use an internet application like Google Chrome to perform a wide variety of web tasks such as viewing web pages and navigating through websites. A web browser can also perform image searches and text searches as well as search the internet for new web pages and content. Some of these tasks are automatically disabled when the internet application is started up and only enabled when the user logs onto the internet. This feature makes it possible for your employees to manage their work even while they are on the clock.
