Ch 1: Network Concepts

About This Chapter

Check out this chapter on network concepts to enhance your knowledge of these computer science topics. Several of the lessons in this chapter can be used to assist you with completing school or homework projects about hardware, data processing, operating systems, and more.

Network Concepts - Chapter Summary

Systems of information are often linked together on networks, and this chapter has been designed to give you an overview of the full range of network concepts that individuals need to understand in order to use telecommunications systems more efficiently. In each lesson our instructors keep you focused on one network concept at a time. Depending on your knowledge of telecommunications systems, you may need to go through every lesson in this chapter, or you may only need to brush up on a few areas. These lessons have been designed for learners of all skill levels, so you can study at a pace that works for you. When you complete the chapter, you should be ready to:

  • Describe telecommunications system components
  • Identify the resources of information systems
  • Analyze the different functions of telecommunications hardware
  • Check out the types of network interface cards (NIC)
  • Define firmware, device drivers, and utility software
  • Compare distributed processing and computer networks
  • Examine the functions of a LAN card
  • Differentiate between extranet and intranet
  • Explain the components of the Internet packet
  • Assess open systems interconnection (OSI)
  • Summarize the OSI model and the application layer
  • Critique predicted trends in networking

Organizations rely upon intranets and extranets to share information, communicate with employees, suppliers and customers, and enable collaboration on projects. This lesson explains how intranets and extranets work. It introduces the topics of virtual private networks, tunneling and firewalls.

Internet Packet: Definition & Explanation

10. Internet Packet: Definition & Explanation

In this lesson, we'll define Internet packets and describe Internet packet construction. We'll also discuss the 14 fields comprising a typical data packet and how you can test for and correct packet loss problems, such as signal loss.

OSI Model: Using Open Systems Interconnection to Send and Receive Data

11. OSI Model: Using Open Systems Interconnection to Send and Receive Data

The Open System Interconnection (OSI) model describes how data is sent and received over a network. It consists of seven layers: the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. This lesson discusses how the OSI model works and the role of each layer for transmitting messages.

Application Layer of the OSI Model: Definition, Functions & Protocols
