    [​IMG]Internet architecture


    Even though the Internet is still a young technology, it's hard to imagine life without it now. Every year, engineers create more devices to integrate with the Internet. This network of networks crisscrosses the globe and even extends into space. But what makes it work?

    To understand the Internet, it helps to look at it as a system with two main components. The first of those components is hardware. That includes everything from the cables that carry terabits of information every second to the computer sitting in front of you.

    Other types of hardware that support the Internet include routers, servers, cell phone towers, satellites, radios, smartphones and other devices. All these devices together create the network of networks. The Internet is a malleable system -- it changes in little ways as elements join and leave networks around the world. Some of those elements may stay fairly static and make

    up the backbone of the Internet. Others are more peripheral.
    These elements are connections. Some are end points -- the computer, smartphone or other device you're using to read this may count as one. We call those end points clients. Machines that store the information we seek on the Internet are

    servers
    . Other elements are nodes which serve as a connecting point along a route of traffic. And then there are the transmission lines which can be physical, as in the case of cables and fiber optics, or they can be useless signals from satellites, cell phone or 4G towers, or radios.

    All of this hardware wouldn't create a network without the second component of the Internet: the protocols.Protocols are sets of rules that machines follow to complete tasks. Without a common set of protocols that all machines connected to the

    Internet must follow, communication between devices couldn't happen. The various machines would be unable to understand one another or even send information in a meaningful way. The protocols provide both the method and a common language for machines to use to transmit data.
    We'll take a closer look at protocols and how information travels across the Internet on the next page

    Step3:By Clicking Devive Manager Tab u will get list of items that are connected and can be connected to your PC then go for portsetting

    [​IMG]

    step4:double click the PORT(COM&LPT) then u will get list of devices

    Step5:double click the Communication port(COM1),Communication port(COM2)..etc

    Step6:After double click communication port(COM1) goto port settings tab

    [​IMG]

    Step7:In port setting tab There is bits per second and default value is 9600

    Step 8:Change the default value to 128000

    [​IMG]

    Step9:And also change the Flow Control from none to Hardware

    [​IMG]Step10:press ok and exit the device manager and restart the pc sp that the changes could be applied


    By doing these steps your internet Connect speed will automatically increases...Thanks for visiting us...have a nice day...
