URL, also known as a web address is short for uniform resource locator. In other words, The first part of the address is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes. Basically, in order to browse for a website, you need to add in the URL in order to view it. A URL is a formatted text string used by Web browsers, email clients and other software to identify a network resource on the Internet. The URL is categorized into 4 sections. They are URL protocol which means a network protocol to access a resource, URL host which means a computer other network device, URL location which defines as a path to one specific network resource on the host and absolute VS. Relative URL which the former term relates full URL featuring all 3 substrings while the latter describes about certain cases when within Web pages, URLs can contain only the one location element.
HTML.
HTML, short for hyper text mark up language is a markup language which consists of markup tags from which is utilizes to describe web pages. HTML tags interprets the keywords surrounded by angle brackets like <HTML> .Regularly, it comes in pairs. They allow all the cool stuff like images and tables and stuff, just by telling your browser what to render on the page. Different tags will perform different functions. The tags themselves don’t appear when you view your page through a browser, but their effects do. For example: <b> and </b> the first tag in a pair is the start tag, the second tag is the end tag. <b>These words will be bold</b>, and these will not. In addition to this,HTML documents, also known as web pages, describe web pages and contain HTML tags. The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicitly presentational HTML markup.
Javascript.
JavaScript is the most popular scripting language on the internet, and works in all major browsers, such as Internet Explorer, Firefox, Chrome, Opera, and Safari. JavaScript, also known as ECMAScript, is a prototype-based, object-oriented scripting language that is dynamic, weakly typed and has first-class functions. It is also considered a functional programming language like Scheme and OCaml because it has closures and supports higher-order functions. The purposes of a javascript are that JavaScripts gives HTML designers a programming tool, JavaScript can put dynamic text into an HTML page, JavaScript can react to events, JavaScript can read and write HTML elements, JavaScript can be used to validate data, JavaScript can be used to detect the visitor's browser and JavaScript can be used to create cookies.morover, javascript can be use without purchasing a license and is usually embedded directly into HTML pages. Did you know that Java and JavaScript are two completely different languages in both concept and design? Java (developed by Sun Microsystems) is a powerful and much more complex programming language - in the same category as C and C++.
Applets.
An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser's Java Virtual Machine (JVM). In other words, In computing, an applet is any small application that performs one specific task that runs within the scope of a larger program, often as a plug-in.[1][2] An applet typically also refers to Java applets, i.e., programs written in the Java programming language that are included in a web page. Every version of the Java Software Development Kit (aka JDK) includes a set of demo Applets which includes source code.some of which are :
Some applets perform as a stand alone application whereby it is Provided that an applet is hosted by an operating system, it can function as any other normal software application but is small in size and performs only a small set of tasks. Examples of applications often classified as applets are all of the accessories bundled in Microsoft Windows (such as Windows Notepad or Microsoft Paint).
Blogs.
A blog is a personal diary. A daily pulpit. A collaborative space. A political soapbox. A breaking-news outlet. A collection of links. Your own private thoughts. Memos to the world.Your blog is whatever you want it to be. There are millions of them, in all shapes and sizes, and there are no real rules.In simple terms, a blog is a website, where you write stuff on an ongoing basis. New stuff shows up at the top, so your visitors can read what's new. Then they comment on it or link to it or email you. Or not.Since Blogger was launched in 1999, blogs have reshaped the web, impacted politics, shaken up journalism, and enabled millions of people to have a voice and connect with others.moreover, a blog is organized in reverse-chronological order, from most recent entry to least recent, a blog is normally public -- the whole world can see it.In addition to that,The entries in a blog usually come from a single author and are usually stream-of-consciousness. There is no particular order to them. For example, if I see a good link, I can throw it in my blog. The tools that most bloggers use make it incredibly easy to add entries to a blog any time they feel like it.In this article, you will have a chance to enter the world of blogging. You will even learn how to create your own blog and publish it to the world.
Wikis.
The first wikis appeared in the mid-1990s. WikiWikiWeb was the first wiki. Ward Cunningham started developing WikiWikiWeb in Portland, Oregon, in 1994, and installed it on the Internet domain c2.com. A wiki is a Web page that can be viewed and modified by anybody with a Web browser and access to the Internet. This means that any visitor to the wiki can change its content if they desire. While the potential for mischief exists, wikis can be surprisingly robust, open-ended, collaborative group site. Examples include community websites, corporate intranets, knowledge management systems, and note services. Or in other words, Wiki promotes meaningful topic associations between different pages by making page link creation almost intuitively easy and showing whether an intended target page exists or not.apart from that, the purposes of wikis are that some permit control over different functions (levels of access). For example editing rights may permit changing, adding or removing material. Others may permit access without enforcing access control. Other rules can be imposed for organizing content.
FTP.
FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network. You can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, or access online software archives. Keep in mind, however, that many FTP sites are heavily used and require several attempts before connecting.in other terms, this defines the standard protocol used to transferfiles across the internet, or a similar network, between computer systems used for TCP based network, such as the internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server.[1] FTP users may authenticate themselves using a clear-text sign-in protocol but can connect anonymously if the server is configured to allow it.
Plug-ins.
Plug-ins are software modules that add to the functionality of an application. Many applications use plug-ins, including Photoshop, and web browsers such as Firefox and Internet Explorer.Plug-ins can have many different functions. Web browsers typically use plug-ins to expand the range of formats they can display (e.g., Acrobat documents, QuickTime or Adobe Flash content). When the web browser encounters a format it doesn't support, it looks for a plug-in that does. A plug-in can launch its own viewer, appear within a browser window, appear in an embedded frame (within a window that may also contain HTML), or run in the background. How you install a plug-in depends on both the parent application and the plug-in itself. In many cases, the directory or folder where you place your plug-in(s) may have an installer.
Filter.
It is a program that accepts a certain type of data as input, transforms it in some manner, and then outputs the transformed data. For example, a program that sorts names is a filter because it accepts the names in unsorted order, sorts them, and then outputs the sorted names.
In addition to this, a pattern through which data is passed. Only data that matches the pattern is allowed to pass through the filter.
Moreover, in paint programs and image editors, a filter is an effect that can be applied to a bit map. Some filters mimic conventional photographic filters, but many transform images in unusual ways. A pointillism filter, for example, can make a digitized photograph look like a pointillist painting.
This is an example:
Anyone wishing they could filter out stuff that goes to their Google reader than take a look at this free service I come across:
http://www.feedrinse.com/ (http://abcde.co.uk/links/index.php#F)
It allows you to apply filters to all your feeds.
Just export your feeds and import them into feed rinse then export them out of feed rinse, replace your existing feeds with the feed rinse ones and you're done .

Internet security.
Internet security is a branch of computer security specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing. Some of the known anti virus programmes as it is related to internet security are Norton , kaspersky,McAfee, titanium and many more.Different methods have been used to protect the transfer of data, including encryption.
Nowadays, there are different types of network security, which includes Network layer security that have been developed for securing communications on the Internet
And IPsec Protocol which is designed to protect communication in a secure manner using TCP/IP.Moreover, This protocol is designed to protect communication in a secure manner using TCP/Ineternet protocol. It is a set of security extensions developed by IETF, and it provides security and authentication at the IP layer by using cryptography
.
