  Understanding HTML The internet has become a vital part of our lives. By   use of the internet, we can share data and information across the world instantly. It is worldwide network of computers. A computer on the internet that shares available data and information is called server . A computer on the internet that accesses data and information from the server is called client . A server stores files and information in the form of websites. These websites consists of millions of webpages. A webpage is a page that carries text, graphics, video, audio and links to other web pages. These webpages are written in HyperText Markup Language (HTML). What is HTML? HyperText MarkUp Language (HTML) is a computer language used to create webpages. Tim Berners-Lee and his team developed this language at CERN, an European Scientific Organization based in Geneva, Switzerland. HTML describes the content, format and layout in which a web page should be displayed over the World Wide ...

The Requirements for internet connection Computer System A computer with a good CPU speed is the prime requirement to access the Internet. This can be a normal desktop, or a laptop. This computer will act as the client or the workstation. Today's websites are a mix of text, sound and images so the contents of the websites might be heavy. Hence, more the speed of the CPU better will be the performance of Internet access. The computer should have at least 1 GB of RAM. The higher the size of the RAM, the better is the speed of your computer. The computer should have at least 1 GB of free hard disk space. But this must not be a problem because most of today's computers come with at least 500 GB hard disk space. Besides the above, a sound system with a microphone, speakers and devices like a printer, scanner, etc. are desirable but not compulsory. Modem A modem is a device that converts the analog signals to digital signals and the digital signals to analog signals. It h...

Difference between Internet and Intranet? Internet refers to a global network that connects a large number of computers, by using routers. All computers on the internet communicate with one another using the Transmission Control Protocol/Internet Protocol (TCP/IP). Intranet is similar to internet but they differ in size and ownership. Intranet is also a computer network (especially LAN) which is privately owned by a particular individual or an organization. Intranet uses TCP/IP for sending and receiving information but it is accessible to organization members only.

What is Internet? Internet refers to a global network that connects a large number of computers, by using routers. All computers on the internet communicate with one another using the Transmission Control Protocol/Internet Protocol (TCP/IP). Evolution of Internet The foundation of the internet was given in the year 1969 when the US Department of Defence sponsored a project to connect itself with the different universities to share information with their colleagues in other U.S. cities. The project was named ARPANET (Advanced Research Projects Network) .The main motive behind this project was to develop a secure network that survives and works even after nuclear attack. By 1971 there were 30 universities participating in ARPANET. Computers in ARPANET use certain rules to communicate with each other. These set of rules are termed as Protocols. The protocol used by ARPANET was NCP (National Control Protocol). By the time NCP was out of use and TCP/IP came into the world of net...
