Newly upgraded and with a new extended security section, this is the essential course for anyone who needs a solid understanding of TCP/IP networks. The course describes and explains the concepts and features of TCP/IP, providing a complete introduction to the TCP/IP protocols, services and applications. Assuming no existing TCP/IP knowledge, it covers all aspects of TCP/IP, the Internet and Intranets, including security issues. Common user and system applications are explained (including FTP, Telnet, WWW, DNS, NFS, and SNMP), in addition to a detailed examination of the major protocols, message formats and addressing methods.

Attendees will construct and configure a small routed network and also participate in network intrusion. These practical exercises reinforce the topics and skills taught during the course.

An understanding of networking principles and terminology is required.

TCP/IP Fundamentals Training Course in Finland

Finland is a country located in northern Europe. Helsinki is the capital and largest city of the country. The majority of the people are Finns but there is also a small Lapp population in Lapland, where the country is famous for the Northern Lights. Finland's national languages are Finnish and Swedish.

Known for its vast forests, lakes, and natural beauty, Finland is one of the world's largest producers of forest products, such as paper, pulp, and lumber. One of the world's largest sea fortresses Suomenlinna, Rovaniemi with the "White Nights", dogsled safaris and of course the Northern Lights are what makes Finland so popular for tourists. Finland is one of the best places in the world to see the Northern Lights and attracts millions of tourists during its seasons.

Finland is home to a thriving technology industry and is widely recognized as one of the world's leading technology hubs. Companies such as Nokia and Rovio (creator of the popular game Angry Birds) are based in Finland. Some of the key factors that have contributed to Finland's success in technology include; strong investment in research and development, a highly educated workforce and fundings.

Finland has a strong educational system, and is widely regarded as one of the world's most literate countries. In fact, Finland's literacy rate is one of the highest in the world, and its students consistently perform well in international tests of math and reading ability.

Also, as a pioneer in environmental sustainability, Finland is known for its efforts to reduce its carbon footprint and promote clean energy. This Nordic country is also famous for its unique and distinctive cultural heritage, including its traditional folk music and its elaborate traditional costumes.

Helsinki, Finland's capital city, is the country's business center. Helsinki is Finland's largest city, and it is home to many of the country's major corporations and organizations, including many of the country's leading technology firms. The city is also a commercial, trade, and financial center, as well as one of the busiest ports in the Nordic region.
