  • OSI Transport Layer. In this chapter, we examine the role of the Transport layer. The Transport layer also encompasses these functions: Enables multiple applications to communicate over the network at the same time on a single device. Ensures that, if required, all the data is received reliably and in order by the correct application. Employs error handling mechanisms. Learning Objectives–Upon completion of this chapter, you will be able to: Explain the need for the Transport layer.

  • Chapter 6 - Network layer protocols. Chapter summary: Network layer protocols are responsible for end-to-end communications across the network; IP is a connectionless protocol that encapsulates transport layer data into datagrams; IPX is a proprietary standard that performs routing, addressing, and protocol identification; NetBIOS Extended User Interface (NetBEUI) is used by small Windows networks for LAN networking; AppleTalk provides basic networking to small networks.

  • Để cho các máy khác nhau địa chỉ đường mạng liên lạc được với nhau, ta phải dùng thiết bị định tuyến, là thiết bị được kết nối ở tầng thứ 3 trong mô hình OSI (Network Layer), như Router hoặc Switch L3. Do không có thiết bị như Router hay Switch L3 (Router cứng), ta dùng Server với 2 NIC và dùng dịch vụ Routing and Remote Access (RRAS) để thay thế chức năng Router (Router mềm).

  • This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.
