what is an internet service provider ?
Your Internet Service Provider (ISP) is the company you pay a fee to for access to the internet. No matter the kind of internet access (cable, DSL, dial-up), an ISP provides you or your business a piece of a larger pipe to the internet. All internet connected devices run each request through their ISP in order to access servers to download web pages and files, and those servers themselves can only provide you those files through their own ISP. Examples of some ISPs include AT&T, Comcast, Verizon, Cox, NetZero, among many, many others. They may be wired directly to a home or business or beamed wirelessly via satellite or other technology. What Does an ISP Do? We all have some sort of device in our home or business that connects us to the internet. It's through that device that your phone, laptop, desktop computer, and other internet capable devices reach the rest of the world - and it's all done through various ISPs. Let's look at an exampl
Different between dial-up connection and broadband connection
Dial-up A dial-up connection allows users to connect to the internet via their telephone line using a standard 56k modem. The computer literally dials a telephone number provided by the Internet Service Provider and connects to the server's modem and therefore the Internet. Dial-up has a transfer rate of 56 Kilobits of data per second under ideal conditions. Broadband (or High-Speed Internet) The distinctive chatter of a dial-up is rapidly becoming a sound of the past as broadband sweeps the global network. In fact, only 3 percent Internet users still use dial up. It's no mystery why when you consider the enormous benefits: Save Time: Broadband operates from 10 to 20 times faster than a dial-up connection, enabling the speedy transfer of large amounts of data. For instance, downloading a song takes a few seconds versus perhaps 10 minutes with dial-up; e-mailing digital photos is almost instantaneous. Save Money: If you now dedicate a second phone line
DO YOU KNOW ABOUT INTRANET? Intranet Intranet is defined as private network of computers within an organization with its own server and firewall. Moreover we can define Intranet as: Intranet is system in which multiple PCs are networked to be connected to each other. PCs in intranet are not available to the world outside of the intranet. Usually each company or organization has their own Intranet network and members/employees of that company can access the computers in their intranet. Every computer in internet is identified by a unique IP address. Each computer in Intranet is also identified by a IP Address, which is unique among the computers in that Intranet.
Overview Of Internet
Internet Internet is defined as an Information super Highway, to access information over the web. However, It can be defined in many ways as follows: Internet is a world-wide global system of interconnected computer networks. Internet uses the standard Internet Protocol (TCP/IP). Every computer in internet is identified by a unique IP address. IP Address is a unique set of numbers (such as 110.22.33.114) which identifies a computer location. A special computer DNS (Domain Name Server) is used to give name to the IP Address so that user can locate a computer by a name. For example, a DNS server will resolve a name http://www.tutorialspoint.com to a particular IP address to uniquely identify the computer on which this website is hosted. Internet is accessible to every user all over the world.
