HTML stands for Hypertext Markup Language. Hypertext refers to the text with Links. These links may point to sections of the same web page or any other web page within or outside the website. HTML Definition HTML is a language used to create and format web pages. HTML is used to define the structure and format of a web page. HTML will place and format the contents like text, pictures, audio or video data in your web pages. Moreover,you can use Links to connect the related web pages in the form of a website.  Who Invented HTML? HTML was developed by Tim Berners Lee in 1989. TAGS and Elements HTML uses commands called TAGS to create and format different elements and contents of a web page. HTML tags are enclosed within angle brackets <>. For example <b> tag is used to format some text as bold text. Normally, tags work in pairs as shown in the example below. <b> This is bold text. </b> The output of the above HTML command or tag will be as show next in

Topic: Advantages and Disadvantages of Mesh Topology Mesh Topology In a mesh topology, every device on the network is physically connected to every other device on the network. Therefore, data can be sent on several possible paths from source computer to destination computer. Mesh topology is more reliable with better performance. Mesh Network Topology is mostly used in wide area networks where reliability is important. Advantages of Mesh Network Topology 1. Since, there are many links to transfer data, Mesh topology gets rid of the traffic problem . Data may be transferred through different links. 2. If one link becomes unusable, it does not disturb the whole system . Other links can be used for communication. 3. Since each node has physical connection with other nodes, therefore, one node can transfer data to many nodes at the same time. Disadvantages of Mesh Network Topology 1. It is very expensive due to implementation of multiple links for each no

Tree Topology Actually, a Tree topology is the combination of two topologies: bus topology   and star topology . A tree topology combines the characteristics of bus and star topologies. It consists of groups of computer connected as star topology. These groups are then connected to a central communication medium (bus cable). Advantages and Disadvantages of Tree Network Topology Advantages of Tree Network Topology 1. Many software and hardware vendors support tree topology . 2. It provides point-to-point wiring for individual groups. Disadvantages of Tree Network Topology 1. If the main backbone line breaks, the entire tree network goes down . 2. A tree network is more difficult to configure and maintain. 3. If any hub fails, related segment will be removed from the network.
