Introduction to TCP/IP
TCP/IP model development:
The late-60s The Defense Advance Research Projects
Agency (DARPA) originally developed Transmission
Control Protocol/Internet Protocol (TCP/IP) to
interconnect various defense department computer
The Internet, an International Wide Area Network,
uses TCP/IP to connect networks across the world.
The primary duties of the transport layer, Layer 4 of the OSI model, are to transport and regulate the flow of information from the source to the destination, reliably and accurately. End-to-end control and reliability are provided by sliding windows, sequencing numbers, and acknowledgments
To understand reliability and flow control, think of someone who studies a foreign language for one year and then they visit the country where that language is used.
Tầng 1: Tầng vật lý (Physical Layer)
Tầng vật lý định nghĩa tất cả các đặc tả về điện và vật lý cho các thiết bị. Trong đó bao gồm bố trí của các chân cắm (pin), các hiệu điện thế, và các đặc tả về cáp nối (cable). Các thiết bị tầng vật lý bao gồm Hub, bộ lặp (repeater), thiết bị tiếp hợp mạng (network adapter) và thiết bị tiếp hợp kênh máy chủ (Host Bus Adapter)- (HBA dùng trong mạng lưu trữ (Storage Area Network)).
The U.S. Department of Defense (DoD) created the TCP/IP reference model because it wanted a network that could survive any conditions.
The TCP/IP model has since become the standard on which the Internet is based. In 1992 the standardization of a new generation of IP, often called IPng, was supported by the Internet Engineering Task Force (IETF). IPng is now known as IPv6.
Chapter 4 introduction to TCP/IP protocols. Objectives in this chapter: Identify and explain the functions of the core TCP/IP protocols; explain how the TCP/IP protocols correlate to layers of the OSI model, discuss addressing schemes for TCP/IP in IPv4 and IPv6 protocols,... Inviting you to refer.
The two dominant networking models are the Open Systems Interconnection (OSI) and the Internet model (TCP/IP).The first is a theoretical framework; the second is the actual model used in today's data communications. In Chapter 2, we first discuss the OSI model to give a general background. We then concentrate on the Internet model, which is the foundation for the rest of the lecture.
Chapter summary: DHCP assigns IP addresses by using automatic, manual, or dynamic allocation; DNS resolves host and domain names into IP addresses; WINS resolves NetBIOS names into IP addresses; ping tests whether one computer running TCP/IP can communicate with another computer on the network;...and other contents.
Learning objectives of this chapter include: Understand the architecture of the OSI model, understand the layers of the OSI model and their functions, understand the architecture of the TCP/IP Protocol Suite, differentiate between the OSI model and the TCP/IP Suite, differentiate between the three types of Internet addresses.
Chapter 2 - The OSI model and the TCP/IP protocol suite. Upon completion you will be able to: Understand the architecture of the OSI model, understand the layers of the OSI model and their functions, understand the architecture of the TCP/IP Protocol Suite, differentiate between the OSI model and the TCP/IP Suite, differentiate between the three types of Internet addresses.

f you are like the rest of the networking community, you probably have
many certifications. Certification is one of the best things you can do for
your career in the computer or networking field. It proves that you know
what you’re talking about when it comes to the area in which you are
In this book, you’ll find out what the Network+ exam is all about. Each
chapter covers a part of the exam. At the end of each chapter, there are
review questions to help you prepare for the exam....
This lab will help to develop a better understanding of the seven layers of the OSI model. Specifically
as they relate to the most popular functioning networking model in existence, the TCP/IP model. The
Internet is based on TCP/IP. TCP/IP has become the standard language of networking. However,
the seven layers of the OSI model are the ones most commonly used to describe and compare
networking software and hardware from various vendors. It is very important to know both models
and be able to relate or map the layers of one to the other.
Application Layer Functionality and Protocols. In this chapter, you will learn to:
Describe how the functions of the three upper OSI model layers provide network services to end user applications.
Describe how the TCP/IP Application Layer protocols provide the services specified by the upper layers of the OSI model.
Define how people use the Application Layer to communicate across the information network.
Describe the function of well-known TCP/IP applications, such as the World Wide Web and email, and their related services (HTTP, DNS, SMB, DHCP, SMTP/POP, and Telnet)....
This chapter is an introduction to the application layer. In the next eight chapters we introduce common client-server applications used in the Internet. In this chapter, we give a general picture of how a client-server program is designed and give some simple codes of their implementation. The area of network programming is a very vast and complicated one; it cannot be covered in one chapter. We need to give a bird’s-eye view of this discipline to make the contents of the next eight chapters easier to understand.
Chapter 3 - Network connections. Chapter summary: Use the Network And Dial-Up Connections window to manually install and configure the basic Windows 2000 networking components; use the Local Area Connection Properties dialog box of a network interface adapter to install, remove, and configure the TCP/IP networking components for that specific network interface adapter; use the Internet Protocol (TCP/IP) Properties dialog box to configure basic and advanced TCP/IP properties.
Chapter 8 - TCP/IP fundamentals. Chapter summary: The TCP/IP protocols were developed to support systems that use any computing platform or operating system; the TCP/IP protocol stack consists of four layers: link, internet, transport, and application; IP uses the ARP protocol to resolve IP addresses into the hardware addresses needed for data-link layer protocol communications;...and other contents.
Chapter 9 - TCP/IP routing. Chapter summary: DHCP assigns IP addresses by using automatic, manual, or dynamic allocation; DNS resolves host and domain names into IP addresses; WINS resolves NetBIOS names into IP addresses; ping tests whether one computer running TCP/IP can communicate with another computer on the network;...and other contents.
Describe the structure of a network, including the devices and media that are necessary for successful communications. Explain the function of protocols in network communications. Explain the advantages of using a layered model to describe network functionality. Describe the role of each layer in two recognized network models: The TCP/IP model and the OSI model. Describe the importance of addressing and naming schemes in network communications.
Data Communications and Networking, 3/e provides a comprehensive and current introduction to networking technologies. The book is accessible to students from all backgrounds and uses hundreds of figures to visually represent concepts. The new edition has been completely updated to reflect the constantly changing world of network technologies. Enhanced coverage of bluetooth, wireless, satellites, as well as four new chapters on security have been added. The third edition has transitioned from using the 7-layer OSI model to the 5-layer Internet Model.
