B.4 Problems when accessing the Internet or remote network

!Cant’s access the Internet or remote network There are four possibilities to causes this problem

1.The connection between the computer and the Modem

2.The connection between the Modem and your NSP

3.The connection between your NSP and your ISP

4.The connection between your ISP and the Internet

To isolate the problem, you can verify IP connectivity with following steps by running a ping <IP address> command. For example, ping 192.168.254.254.

1.Ping the IP address of your PC. If you get a response back, proceed to next step directly. If you don’t get a response back, check that:

-The network adapter card is installed.

-The TCP/IP protocol is installed.

-The TCP/IP protocol is bound to the network adapter.

2.Ping the IP address of your Modem. If you get a response back, proceed to next step directly. If you don’t get a response back, the problem lies between your PC and your Modem:

-Check the cables.

-Check the hub.

-Make sure that your PC and your Modem belong to the same IP sub network.

-Observe the TX and RX LEDs to see if data traffic flow appears to be normal

3.Ping the DNS server.

!If the Modem is configured to bridging mode

-Be sure to reboot the Modem if you have made any changes with configuration.

-All IP addresses must be in the same IP sub network.

!If the Modem is configured to routing mode

Heritage specifications

IBM, or International Business Machines Corporation, is a global leader in technology and consulting, with a heritage that spans over a century. Established in 1911, IBM initially emerged from a merger of four companies, and it has since evolved into one of the most influential players in the tech industry.

One of the main features of IBM’s legacy is its commitment to innovation. The company has a long history of technological breakthroughs, including the development of the first programmable computer, the IBM 701, in the early 1950s. IBM has also been at the forefront of many pivotal technologies, including mainframe computers, which became central to large-scale enterprise computing. The System/360, introduced in 1964, revolutionized the industry by offering a compatible range of computers that could run the same software, a concept that helped define the standardization of computer systems.

IBM’s contributions to artificial intelligence, particularly through its Watson platform, are another hallmark of its heritage. Watson gained international fame for its success on the quiz show Jeopardy! in 2011, showcasing advanced natural language processing capabilities and machine learning techniques. This technology has since found applications in various fields, from healthcare to finance, significantly transforming data analysis.

Another key characteristic of IBM is its focus on research and development. With an impressive portfolio of patents, IBM consistently ranks among the top patent holders annually. Their research endeavors have led to significant advancements in quantum computing, with initiatives like the IBM Quantum Experience making quantum technologies accessible to developers and researchers.

Sustainability is also a priority for IBM, with programs aimed at promoting environmental responsibility. The company has committed to achieving net-zero greenhouse gas emissions by 2030, reflecting the growing importance of sustainability in technology practices.

In summary, IBM's heritage is characterized by a strong legacy of innovation, technological leadership, and a commitment to addressing contemporary challenges in business and society. From pioneering mainframe systems to leading the charge in AI and quantum computing, IBM continues to shape the future of technology while maintaining a visionary outlook towards a sustainable and inclusive digital world.
