CONNECTING TO INTERNET

              To connect to the Internet, you need three main things:

              1.  A Device: This could be a computer, laptop, or mobile phone.
              2.  A Connection  Device: This is usually a modem or  a router, which  helps your  device connect  to the
                 Internet.

              3.  An Internet Service Provider (ISP): This is a company that provides the service that lets you access
                 the  Internet.  They  offer  Internet  connectivity  through  different  methods like  phone  lines or  wireless
                 networks.
              Examples of ISPs include companies like, Airtel, BSNL, Jio, etc. These companies provide the Internet service

              that allows you to go Online and use websites, send emails, and more.
              Types of Connections

                 Wired Connections: These occur when a computer connects to the Internet using a physical wire, such as
                 an Ethernet cable. This cable is used to connect the computer to the modem, which in turn connects to the
                 ISP through a phone line.

                Wireless Connections: Computers can connect to the Internet wirelessly using technologies like Wi-Fi. For
                 example, laptops require a wireless Internet card to connect to a modem without using cables.
              Bandwidth

              Bandwidth refers to the capacity of a network to transmit data within a specific timeframe. To illustrate,
              imagine a pipe: the wider it is, the more water it can carry. Similarly, a network’s bandwidth determines the
              amount of data it can handle. For digital devices, bandwidth is typically measured in bits per second (bps),
              while analog devices use cycles per second, or Hertz (Hz). Data transfer speeds, including Internet speeds, are
              commonly expressed in terms of bits per second.

              1 Kbps = 1,000 bits per second,
              1 Mbps = 1,000 Kilobits per second,
              1 Gbps = 1,000 Megabits per second.

              Internet Browser

              To access information on various websites, you need an Internet browser. An Internet browser is a software
              application on your computer or laptop that allows you to visit and navigate different websites. Examples
              include Google Chrome, Mozilla Firefox, and Internet Explorer.



               SESSION             8   Communication and Networking—Internet Browsing

              Imagine a large system where millions of computers are interconnected, sharing information and resources
              seamlessly. This  interconnected system, called the Internet, acts like a global highway  for data,  allowing
              devices to exchange messages, access files, and collaborate in real time. The Internet forms the foundation
              for many technologies and tools we use every day, including email, social media, and online games. One of its
              most impactful creations, however, is the World Wide Web—a system that revolutionised the way we access
              and share information. Let’s explore how this incredible innovation works.
