Internet is a network of networks in which various computers connect with each other throughout the world. The connection to other computers is possible with the help of the Internet Service Provider (ISP). Each Internet user depends on a dial-up connection to connect to the Internet. This has many disadvantages like very poor speed etc. To solve the problem, Internet data can be transferred through Cable networks wired to the user’s computer. Different types of connections used are Public Switched Telephone Networks (PSTN) connection, Integrated Services Digital Network (ISDN) connection and Internet via Cable networks. Various advantages are high availability, high bandwidth to low cost, high speed data access, always on connectivity etc.
Communication between computers is a major part of the PC computing Industry. Thanks to the World Wide Web (www), no computer user is an Island. Whether using a dialup modem or broad band technology, virtually all PCs can be connected to other computers, enabling them to share files, send and receiving email, and access the Internet.
With the explosive growth of the internet, modem and network technologies were joined because both could use the same client software and protocols. Today, the most popular suite of networking protocols –TCP/IP – is used on both Local Area Network (LANs) and the internet. When you dial into an Internet Service Protocol (ISP), you are actually connecting to a network using a modem instead of a network interface card, and when you use most broadband services, your path to the internet typically starts with a network interface card, built in network card, built in network port, network – to – USB adapter, or even a wireless connection.
Thanks to the combination of huge multi megabyte downloads needed to update software and support hardware, dynamics websites with music and full – motion videos and increased demand for online services, even the fastest dial up modem (such as mtn fastlink,
